Best Working SSD / Storage Adapters for Raspberry Pi 4 / 400

Storage Adapter Guide
Storage Adapter Guide

To this day it can still be treacherous to buy a storage adapter for your Raspberry Pi 4. There are many that will not work properly and perform very poorly.

I’ve covered which adapters work and don’t work in my Native USB Booting Guide as well as my old “workaround” SD + SSD method guide and over the years people have submitted hundreds of comments about which adapters do and don’t work.

From everything we’ve learned together in the comments and adapters I personally own/use I wanted to compile this information into a new “Best Storage Adapters for Raspberry Pi 4” list. Let’s get started!

How to choose a Pi SSD storage solution

There are a few different considerations and tradeoffs you need to weigh when you’re choosing a storage adapter/enclosure as well as the drive itself. The main considerations are:

  • Specific project requirements
  • Power
  • Performance
  • Budget

The easiest place to start is with your specific project requirements. Is this Pi going to be somewhere where you are okay with having an extra adapter/enclosure and SSD laying around? If you’re going to be using the Pi in something like a drone/vehicle then you may want to go with a USB thumbdrive style ultracompact SSD that plugs directly into a USB port and has no wires or adapters/enclosures. There are also lots of cases available specifically for the Pi that add an additional storage slot (such as M.2 SATA, the older m-SATA style, etc.) to the Pi that may work better with a tightly integrated build.

How much power is going to be available? Is your Pi going to be running off a battery where you want to use as little energy as possible? Do you have AC outlets around? Are you willing to add a powered USB hub to your setup? If your Pi is going to be sitting in a corner in the basement / a closet / some place like that then you can plan to have a powered USB hub and plentiful reliable power around. The lowest power options are going to be 2.5″ SATA drives WITHOUT an enclosure (using just an adapter instead with the drive laying in the open). I have never over years of usage used a powered USB hub with a 2.5″ SATA adapter but many enclosures won’t even boot without one.

What level of performance do you require? If your Pi is going to be running a server or hosting a database then you need a drive that has high random I/O performance as well as large throughput. Performance has a cost though both in power and budget. The highest performance NVMe drives are the most expensive and the NVMe enclosures are the most power hungry class of storage adapters and almost universally require a powered USB hub to be integrated into your setup but we’ll cover this more later in the “Power Requirements” section.

And finally what type of budget do you have? If you are looking to save money you may be wanting to reuse an old SSD or get one used for very cheap. NVMe is the most expensive and 2.5″ SATA / mSATA SSDs are the cheaper options. Places like eBay can be a great source of very cheap drives as well.

The bottom line is choose the type of solution that meets your project’s needs and your budget!

Top Performing Drives


This is the top performing (and most expensive) drive class! They require more power than other types of drives and the NVMe enclosures often bump the requirements up to potentially requiring a powered USB hub to boot (especially with an enclosure). See the “Power Requirements” section below for more information.

Samsung 970 EVO Plus NVMe SSD

The Samsung 970 EVO Plus is a fantastic drive and has fallen in price substantially. It’s widely available around the world. The smaller capacities (such as the 250GB version) of this drive are perfect for the Pi! This is the top performance option without going into the “Pro” series of the lineup which are much more expensive.


Silicon Power A80 NVMe SSD

The Silicon Power A80 is a cheaper alternative to the Samsung lineup while still performing extremely well. The A80’s average score is 8316 compared to the Samsung’s 8955 so they are definitely within striking distance and excellent drives.


KingSpec 3D NAND M.2 NVMe SSD

The KingSpec 3D NAND M.2 NVMe drive is another very affordable choice that is widely available. It performs well and works great with the Pi!



M.2 SATA does not have the transfer rates that M.2 NVMe does but they are quite a bit cheaper and still a fantastic choice for the Pi.

Kingston A400M M.2 SATA SSD

The Kingston A400M is a cheap and reliable M.2 SATA SSD that has over 170 benchmarks on It’s extremely cheap and may even be cheaper than the recommended 2.5″ SATA drives in some countries!


Western Digital Green M.2 SATA SSD

The Western Digital Green M.2 SATA drive is the #26th most popular storage device overall on so it definitely works well and is very affordable. This is another great budget option that can often come in at a lower cost (depending on availability, country and other market factors) than 2.5″ SATA SSDs often do while having a much lower profile!


2.5″ SATA

2.5″ SATA drives are limited by the transfer speed of the SATA interface like the M.2 SATA drives. On the Raspberry Pi this is not as important as on desktop. This is usually the cheapest option and performance is still fantastic!

Kingston A400 2.5″ SATA SSD

The Kingston A400 has been a great drive to use with the Pi for years. It’s reliable, widely available around the world, has low power requirements and performs very well. It’s also very affordable. This drive has been benchmarked over 1000 times at and is the #1 most popular SSD among the Pi community!


Crucial BX500 2.5″ SATA SSD

The Crucial BX500 is another great choice for a drive to use with the Pi. It’s the 2nd most popular SSD benchmarked with over 840 benchmarks submitted. Low power requirements and widely available!


Western Digital Green 2.5″ SATA SSD

The Western Digital Green 2.5″ SATA SSD is another option to investigate. Depending on your country and other market factors this may come in as the best deal. It’s a solid performer and commonly shows up on the storage benchmark.



Portable SSDs are ones that are designed to be used through USB and aren’t meant to be installed internally. The nice thing about these is they do not require a storage adapter. They are also extremely fast. The ones recommended here will beat 2.5″ SATA drives on the performance benchmarks since internally they are usually M.2 SSDs inside a fancy outer shell. They’re usually more expensive than internal drives but not quite as expensive as the top performing internal NVMe drives. Tends to be cleaner than a adapter/enclosure setup but not as clean as the ultracompact setup.

Samsung T5 Portable SSD

The Samsung T5 Portable is one of the most popular USB SSDs for the Raspberry Pi with over 350 unique benchmarks. It’s also one of the fastest with an average score of over 8300 points! No storage adapter required for this one, it is a USB based drive and will plug right in.


SanDisk Extreme Portable SSD

The SanDisk Extreme Portable is a very small portable SSD that can easily be put on a keychain or a loop with the built in notch. It’s also very fast with an average score of over 8,000. The drive has been tested over 147 times making it one of the more popular ones to use with the Raspberry Pi.


Ultra Compact

The cleanest possible setup option. The drive will only plug into your USB port and stay there taking up no extra footprint and adding no extra cables. These recommendations are both actually faster than 2.5″ SATA drives (internally they are M.2 NVMe drives and they perform at that level). You pay a premium for this option vs. something like a 2.5″ SATA setup but lower capacities are much more affordable.

Orico GV100 NVMe SSD

The Orico GV100 is a portable NVMe usb-stick style drive. It’s extremely fast due to actually being a true NVMe drive in a very compact form. This is an excellent choice if you are building a setup that has very limited space or having a dangling adapter/enclosure would be problematic.


SanDisk Extreme Pro SSD

The SanDisk Extreme Pro USB SSD is a true solid state drive. This is different than a typical “flash drive” which uses extremely cheap memory and has very low random I/O performance/throughput compared to a real solid state drive. I’ve used both the USB 3.1 and USB 3.2 variants with the Pi successfully and they benchmark very well!


Recommended Adapters / Enclosures

M.2 NVMe

ICY BOX M.2 NVMe Enclosure

The ICY BOX is basically a giant heatsink that you mount a high performance M.2 NVMe drive inside of. This enclosure is really fast but requires a powered USB hub. Not even the 3.5A adapter can reliably power it! The enclosure works well and will physically feel warm to the touch as it is pulling the heat off your NVMe drive!


ASUS ROG Strix M.2 NVMe Enclosure

If you really want to take things over the top the ASUS Rog Strix M.2 NVMe enclosure uses the latest USB 3.2 Gen2 specification, is RGB capable and works with the Pi! Unsurprisingly, adding the extra lighting does take extra power! A powered USB hub is also required for this enclosure. More widely available than the ICY BOX but tends to be on the expensive side.



UGREEN M+B Key M.2 Enclosure

The UGREEN M+B enclosure is a great enclosure for the Pi for M.2 SATA 2280 NGFF drives. It supports both B-key and M-key drives. Does not support newer NVMe drives. As with other types of enclosures it requires more power than other options!


Argon ONE Pi 4 M.2 Case

The Argon ONE M.2 is a M.2 SATA Pi 4 case / storage solution. With the case and M.2 SATA expansion board you can completely enclosure your Pi 4 and have a built in M.2 slot! The M.2 SATA board is sometimes sold separately from the case itself and can be used as well. Does not support NVMe, this is for SATA M.2 drives only!


2.5″ SATA

StarTech 2.5″ SATA to USB 3.0/3.1 Adapter

Both the USB 3.0 and USB 3.1 variants of the StarTech 2.5″ SATA adapter work well with the Pi 4. I’ve used the 3.0 variant with my Pi 4 since launch and it has always worked well. I later bought the 3.1 variant and had the same positive experience. These two adapter variants are my go to adapters for all my Pi related projects that need a fast and easy 2.5″ SATA SSD!



mSATA adapters are getting less common but they are still incredibly useful. Lots of old laptops that came with SSDs have this older style from before the M.2 style slot existed and took over. Often these drives are still very fast and are available for very cheap since they use an obsolete connector that no longer comes on new motherboards. The VL716 isn’t a brand but is instead the name of the chipset that lots of these adapters use. This chipset works great with the Pi!

VL716 mSATA Enclosure

The VL716 mSATA enclosure lets you connect micro SATA drives to the Pi. These drives are an older type of SSD (usually seen in laptops) predating the M.2 slot but are still widely available and perform extremely well!


Power Requirements

Most types of adapters can be powered by the Pi itself. One notable exception is NVMe enclosures. Throughout the years we have had hundreds of comments from people who had no trouble powering 2.5″ SATA enclosures but couldn’t get a NVMe one to work at all without a powered USB hub.

Very large older 3.5″ SATA drives are known to require more power than the Pi can provide as well as some types of very high performance models that were designed to burn more power to get extra performance gains.

For solid state storage older models of solid state drives (SSDs) are also known to draw more power than their newer counterparts. If you have a drive that you think may fall into this category then definitely be on the lookout for power related issues and extra cautious about your power setup. High end “extreme” performance models also tend to draw more power (Samsung 970 NVMe drives* are some of the fastest in the world but also pretty power hungry for the Pi).

Insufficient Power Symptoms

Symptoms of a lack of power to the drive can include the system only booting sometimes (or not at all) or working for a while and then locking up. Just because the drive boots does not mean it is getting enough power.

Some commenters on previous articles have described this as working fine until there was a sudden spike in CPU usage while they tried to do several things at once (high CPU, accessing storage, activating various hardware all at once) and then they would get a lockup/crash.

This is because the Pi is teetering on the edge of not having enough power and that spike caused it to drop enough where the drive actually lost power (likely only for tiny fractions of a second). This is enough instability to easily cause a crash and worse if it happened to be in the middle of writing something important! Usually nothing will happen other than you’ll have to restart the Pi but because of the risk of data loss and eventually corrupting files. That being said, if you’re particularly unlucky you will have to fsck the drive or potentially even reimage it if fsck is unable to repair the damage!

The best answer is to test for stability. Do this by stressing out the Pi and make sure you are doing activities that stress the CPU and storage at the same time like browsing the web, etc. and if you can do that for a few hours/days without a lockup/crash then you have a stable power setup!

Powered USB Hub Solution

For NVMe enclosures and power hungry drives I personally use this Sabrent powered USB hub and have been recommending it here on the blog for a long time:

Sabrent Powered USB 3.0 Hub

The Sabrent powered USB hub delivers a whopping 2.5A of dedicated power for your USB attached devices. This is almost as much as the Pi adapter itself is rated for (3.0A). It will easily power the most thirsty of setups such as NVMe enclosures.


Note: Make sure Amazon doesn’t try to take you to the non-powered version and that it’s the one with the AC adapter that plugs in to provide extra power

If this hub isn’t an option for you and you don’t have one already you can try with it then look in the reviews for people saying that it is working with Raspberry Pi. Some powered USB hubs will not play nice with the Pi so before buying one definitely check reviews and do some careful research about what to expect with the Raspberry Pi!

Oversized Power Adapter Solution

This solution will work for setups that are right on the border of having enough and not having enough power. An example would be if you can get a stable boot but are getting occasional lockups/freezes when the power dips just below the threshold it needs.

If you are using a powerful NVMe drive/enclosure combo like the ICY BOX with a high performance Samsung NVMe drive even with the extra 500 mA it will still not even boot. I have had these oversized adapters and they are great but for a very powerful drive/adapter combination you are going to need more than 500 mA.

It’s a lot less extra wires and one less AC plug though if you are right on the border and just need a little bit more. It will depend on your individual drive/adapter combo whether it’s enough or you will have to go full powered USB hub!

CanaKit 3.5A Power Adapter

The CanaKit 3.5A adapter has an extra half an amp (500 mA) of capacity to give some breathing room to your accessories. This is bigger than the official Pi power supply which provides 3.0A.


In previous articles readers have told me that this specific adapter can be hard to find outside of North America. I tried to link to as many regions as I could find it in but there should be something equivalent in your region (it just likely won’t be specifically designed for the Pi but will be a more generic USB-C charger).

Look for a USB-C power supply rated to supply around 3.5A. 3.0A or lower won’t do much good as that is almost certainly what you already are using. You can use a higher one (at your own risk). The largest one I’ve ever used is my Dell laptop’s 30W USB-C power adapter. It’s probably not a good idea to go too much bigger than this or to even use one this big over the long term (I didn’t, just for occasional testing and as a emergency backup) but USB-C does have some specification improvements related to power management that seem to provide some flexibility here.

Power Limits

The Pi can only pass through a limited amount of extra power. On the Pi 4 this is up to 1.2A of extra power for peripherals (combined) on top of the board’s 3.0A power rating. This is much more than the Pi 2 and some other previous models could do which was only around 0.5A. This also means that getting a power adapter bigger than about 4.2A of rated current is pointless because the Pi won’t allow any more power to flow through to the board to the peripherals through USB anyway even if it’s available.

I’m oversimplifying a little bit to illustrate the point but if you want the full technical details they are available here in the Raspberry Pi USB documentation. The important takeaway is that going much above 3.5-4.0A or so will not actually provide any more power to the Pi because of these limits. If you’ve hit this ceiling and it still isn’t enough you need to go powered USB hub.

I’ve also used ones that charge cell phones to power Pis before and these ones are the most likely to fall into a range close to what the Pi uses. Most of the ones I had around the house for phones were 2.5A (just barely not enough) or 3.0A so it was enough for a backup spare but not enough to provide extra power. Nevertheless, it’s definitely worth it to check what you already have around and see if there are USB-C chargers around to test with!

Note that a powered USB hub essentially bypasses these limits because the power for your peripherals such as your USB storage will come from the AC adapter connection to the powered USB hub instead of the Pi having to provide that power.

Powered USB Hub Troubleshooting

Most hubs including the Sabrent one above can feed back power into the Pi which can cause it to not boot when the power is connected. The reason for this is that the Pi is detecting power and is trying to power on using that source but the current provided isn’t enough for the Pi to actually boot.

The solution to this is to remove the USB hub’s connection from your Pi momentarily and then connect the power. Plug your USB hub back in quickly after reconnecting the Pi’s power (if you have native USB booting set up) and unless you really fumble with reconnecting it you will have it plugged in well before it tries to boot from the SSD!

If this trick doesn’t work then unfortunately you may have a powered USB hub that is not going to work with the Pi. It’s worth checking to see if there are any firmware updates available for your USB hub before you give up on it as some readers have let me know in the comments of previous articles that they were able to get some hubs working after a firmware upgrade!

Verify Drive Performance

You can make sure everything is running correctly (and as fast as it should be) by running my quick storage benchmark. You can run the benchmark with the following one-liner:

sudo curl | sudo bash

This will give you a score you can compare to the other Raspberry Pi Storage Benchmark results and make sure that you are getting an equivalent speed to your peers with the same device!

  1. James,
    Many thanks for this write up. Made me realize how far along the Pi has come ! The steps are easy to follow. Happy user of RPi4 (4 GB) with Ubuntu Mate 20.10 with Kingston Sata SSD and USB MSATA enclosure (Adwits). The setup does not require external USB power, but might try that out. The aluminium enclosure does heat up a bit … 35 deg Celsius ambient temperature for multiple months here in India does make cooling an interesting project

    1. Hey Amar,

      No problem and thanks for the kind words! The mSATA enclosure is a great setup. I still use these drives a lot in both the USB stick factor and enclosures!

      They do get super hot and that is a concern. It’s good that you have an aluminum enclosure that can basically act as a heatsink and pull that heat off the drive. I have cooked these before in the USB form factor ones that are just open air and don’t have anywhere for the heat to go but the open air. You may even want to put a thermal pad to make contact with the aluminum enclosure if it isn’t (one of those pads like comes with SSDs or motherboards sometimes would work, usually a white putty type feeling pad).

      Glad everything is working and best of luck!

      1. Thanks for the suggestions!
        Indeed, I now have thermal pads inside and heat sink on the outside. The aluminum casing still gets hot, but lesser than before. Will have to measure over a period of time to determine its usefulness.
        Best wishes,

  2. For ICY BOX it’s highlighted that: “This enclosure is really fast but requires a powered USB hub”. Could you share a link to any USB-C to double USB-A (power, data) cable that can be used to power the enclosure?

    1. Hey Max,

      In that paragraph I meant the Sabrent powered USB hub which has it’s own AC adapter. I have seen cables like you’re talking about before though for other types of devices but not for USB SSD/HDD enclosures. The issue is it would still be drawing on the same power source (the Pi) so you need a separate power source (the Sabrent powered USB hub) to provide power to the drive so that it isn’t drawing power from the Pi. Hopefully that helps!

  3. Hi James,
    I wanted to update my prior comments and could not find them. Anyway, I did some more testing with my RPI 4 4G with Home Assistant and tried the 32 bit OS boot with SD and SSD for everything else. This failed after 7 hours. There is an issue with the HA OS on versions above 5.4 for many people. I just saw a couple of people load Debian and Home Assistant on top instead of the HAOS and they have no issues. I believe this confirms there is a HAOS issue?

    Anyway, a couple of questions:
    Are messages sent out when you take the time to respond?
    How would I find older comments that I left on your blog?

    1. Hey Bill,

      Great questions! You can find your own thread by typing “Bill Schatzow” (only one thing came up when I searched it and it was the post where your comment was) in the Google box in the top right of the site or it is located here:

      The messages you guys post on here as comments go up instantly if you post on the same IP and with the same name as you have used before (so the anti-spam filter recognizes you as a real person). If your IP/name you post as changed since your last post or there is a link to another web site included in there it is held for moderation (the links especially since almost every spammer posts a link to somewhere shilling something). Once you’ve had any comment approved on that IP address/name you posted as you are permanently whitelisted automatically by the filter and everything goes up instantly after that!

      That is how I keep the blog from being full of spam like a lot of other sites that look like this style (a WordPress site). The Akismet anti-spam plugin does a fantastic job keeping it clean! If you have a dynamic IP it’s a little annoying but I have left it “dumb” on purpose to protect everyone’s privacy and avoid requiring logins/passwords / using tracking “cookies” / anything invasive like that.

      Loading HA on Debian instead of using the full-blown HAOS sounds really promising, I’d be curious how that works for you if you give it a try!
