Raspberry Pi is putting the ending touches on its M.2 HAT boards for the Raspberry Pi 5. Whereas we anticipate the official boards, the neighborhood is already laborious at work setting up their very personal variations. The first was Pineberry Pi’s Hat Drives and they also set the muse for others to adjust to.
UK Raspberry Pi retailer Pimoroni was already working by itself mannequin and it has lastly landed on our desk. The $13 NVMe Base is a surprising slice of PCB. Simple monochromatic silkscreen belies how useful this little board could be. The inclusion of a personalized flat flex connector, with its private silkscreen to cease mis-connection is a nice contact from Pimoroni.
Nevertheless, is that this the right NVMe board in your Raspberry Pi? Should we determine up a Pineberry Pi board in its place, or anticipate the official Raspberry Pi board? To seek out out that we have now to place the board by way of its paces.
Pimoroni NVMe Base Specs

| M.2 Help | NVMe 2230, 2242, 226 and 2280 |
| Vitality | By the use of FPC |
| Dimensions | 85 x 56 mm |
| Value | $13.50 ($13) |
NVMe Base Design

Straight off the bat, that’s one different conventional Pimoroni design. A clear and straightforward silk show display tells us which NVMe drive sizes we are going to use, and confirms the place we must always at all times be a part of the drive and the ribbon cable between the Pi 5 and the NVMe Base.
There are M2.5 holes which match the HAT footprint of the Raspberry Pi 5, and suggest we are going to mechanically be a part of the two using standoffs.
As a result of the board connects to the underside of the Raspberry Pi 5, it implies that any of the best Raspberry Pi cases just isn’t going to match. Pimoroni will nearly definitely launch an updated Pibow case, nevertheless for now your Raspberry Pi 5 should robust it!
Placing in NVMe Base

Assembly is straightforward, nevertheless we would make the PCIe connection sooner than connecting the standoffs. In some other case the angle of entry for the PCIe port on the Raspberry Pi 5 is excessive and can damage the flat flex cable. It’s additionally worth bearing in mind that the cable have to be precisely aligned and firmly inserted. We misplaced some time with a barely off connection, inflicting us to doubt that our NVMe SSD was working precisely.
NVMe Base Effectivity
That’s the second NVMe board to grace our workbench. The first was the Pineberry Pi HAT Drive which is accessible in a Prime (on excessive of the Pi’s GPIO) and Bottom (beneath the Pi similar to NVMe Base). What we’re going to see with Pimoroni’s NVMe Base is that there isn’t so much distinction between it, and the Pineberry Pi boards.
Let’s start with the boot time. The micro SD boot time for a Raspberry Pi 5 is 21.28 seconds. This speedy boot time is powered by the Raspberry Pi 5’s SDR104 compatibility, so micro SD taking part in playing cards which adjust to this regular will see a giant improve in effectivity. So how does NVMe Base consider? Our boot time was 16.79 seconds (at Gen3 velocity). Study this to Pineberry Pi’s biggest time of 16.56 seconds and we are going to see that there’s nothing between them.
NVMe SSDs add a typical speed-boost to the Raspberry Pi 5. Opening functions will actually really feel faster, as will frequent operations akin to file administration and software program program arrange. Chromium and Firefox every load faster, nevertheless don’t anticipate any NVMe drive to reinforce 1080p video streaming merely however.
Once more to file operations, and we ran two assessments. For the be taught assessments we used dd to be taught the contents of the drive and write to /dev/null. This offers us a raw velocity price. For write speeds we used Raspberry Pi diagnostics to produce us with the sequential write speeds. The assessments had been completed for Gen 1, 2 and three speeds. Discover that formally solely Gen 1 and a few are supported, nevertheless Gen 3 effectivity has been secure for NVMe Base and Pineberry Pi boards.
The usual micro SD card managed 90.5 MB/s be taught, and 30.8MB/s sequential write. That’s our baseline from which to measure. We used a 4TB Lexar NM790 PCIe Gen4 SSD as our benchmark drive, and we moreover used it with the Pineberry Pi board.
| Header Cell – Column 0 | Pimoroni NVMe Base | Hat Drive Bottom (2280) |
|---|---|---|
| PCIe Gen 1 Be taught | 235 MB/s | 235 MB/s |
| PCIe Gen 1 Write | 194.5 MB/s | 194.5 MB/s |
| PCIe Gen 2 Be taught | 416 MB/s | 469 MB/s |
| PCIe Gen 2 Write | 380.9 MB/s | 383.2 MB/s |
| PCIe Gen 3 Be taught | 876 MB/s | 863 MB/s |
| PCIe Gen 3 Write | 761.9 MB/s | 719.1 MB/s |
| Micro SD Be taught | 90.5 MB/s | Row 6 – Cell 2 |
| Micro SD Write | 30.8 MB/s | Row 7 – Cell 2 |
At PCIe Gen 1 speeds the NVMe Base matches Pineberry Pi’s board, 235 MB/s be taught and 194.5 MB/s write. At Gen 2, NVMe Base is slower, displaying 416 MB/s versus 469 MB/s, a large distinction for be taught speeds. Write speeds had been pretty associated, 380.9 MB/s for NVMe Base, 383.2 MB/s for Pineberry Pi.
Our PCIe Gen 3 velocity assessments had been attention-grabbing. NVMe Base managed 876 MB/s be taught speeds, versus Pineberry Pi’s 863 MB/s, a 13MB/s enchancment that we’ll all acknowledge. The write check out was spectacular, NVMe Base managed a formidable 761.9 MB/s, Pineberry Pi hit 719.1 MB/s. So write speeds on the NVMe Base are so much higher than one thing we have now now already examined.
The conclusion of this testing is that on the official Gen 2 speeds, NVMe Base and Pineberry Pi’s Hat Drive are a great match (using the similar drive). Nevertheless tweaking the config and dealing at Gen 3 will in any case current the right speeds, nevertheless NVMe Base merely squeezes a bit of additional from the drive.
Who’s Pimoroni NVMe Base for and what can they do with it?
NVMe SSDs on the Raspberry Pi are nothing new, nevertheless beforehand we needed to make use of a USB 3 to NVMe (or SATA) adapter. This took away a USB 3 port, and restricted us to USB 3 bandwidth and the losses involved from conversion. With devoted PCIe on the Raspberry Pi 5, we have now now so much faster drives, and entry to exceptionally low value storage.
What can we use it for? We’re capable of assemble smaller NAS packages that use the rate of NVMe drives, and the additional extremely efficient Raspberry Pi 5 to supply us so much higher effectivity than the Raspberry Pi 4. Should you want a low-power Arm desktop, then a Raspberry Pi 5 and NVMe could meet your desires for not so much money. Duties which generate huge recordsdata, say video streaming and recording using the myriad of digicam selections, will revenue from the larger, faster storage.
Bottom Line
Pimoroni’s NVMe Base is an affordable means in order so as to add NVMe storage to your Raspberry Pi 5. After we overcame the NVMe config factors (present in every NVMe board we have now now examined) we have now now a reliable and unobtrusive board. It’s a sturdy choice between NVMe Base and Pineberry Pi’s Hat Drive boards. It boils proper right down to the place you’re on this planet. UK Pi followers will naturally head to a UK primarily based etailer as a result of it means there aren’t any import fees. European shoppers would possibly choose Pineberry because it’s primarily based in Poland.
The speed distinction between the two boards is most noticeable at Gen 3 speeds, and whereas it isn’t formally supported, it does work terribly correctly.
