This M.2 2230 NVMe SSD is unlike most others; costs far too much for what it is

An A/E-key M.2 slot, normally occupied by a combo Wi-Fi/Bluetooth card, is something most laptops, mini-PCs and desktop PCs released after 2013 have. The P3/2230, also known as the OAK-2230, lets you make use of that slot to add extra storage space, faster than any SATA III SSD. Naturally, there are several drawbacks to this approach.

It's 2026, and most computers ship with 4-lane PCIe 4 NVMe SSDs offering sequential read speeds up to 7.9 GB/s, best-case scenario. The bad part is, the average laptop or mini-PC now comes with just one or two B/M-key M.2 NVMe SSD slots, and no SATA III SSD compatibility, meaning internal storage expansion options are limited.

The average 2016-to-2020-era laptop is likely to feature one PCIe 3 B/M-key NVMe SSD slot, and one SATA III SSD/HDD slot. 2013 to 2015 systems are likely to only have one or two SATA III SSD/HDD slots.

What makes all those machines from different eras similar is that they all sport an extra M.2 slot with PCIe 3 speeds (depending on the platform, PCIe 4 is possible, too) that gets little attention, and can technically be used to add more storage. 2012 and 2013 were the years when M.2 Wi-Fi card slots with a combined A+E key took over from mini-PCIe slots, while PCIe 2 was superseded by PCIe 3, enabling speeds of 0.9 GB/s per lane. 13 years on, we still get that exact A/E-key M.2 slot in most mini-PCs, laptops, and desktop computers. Time to show it some love.

CWWK P3-2230/Oaknode OAK-2230 puts neglected M.2 slot to good use

The CWWK/Oaknode SSD, which seems to be the same product with slightly different branding, comes in 3 capacity variants, all costing at least 2x as much as one would expect given the specs on offer:

  • "Lianyun MAP1202" controller [actually a Maxio MAP1202 - ?];
  • 256 GB, 512 GB, 1024 GB;
  • claimed speeds of up to 890 MB/s via the sole PCIe 3 lane;
  • "graphene copper" heat dissipation pad;
  • Amazon.com links: Seller 1, seller 2;
  • Aliexpress links: Seller 1, seller 2.

Prices are on the higher side, with the 1-TB option costing way over $200, and the cheapest 256-GB variant starting at way over $80.

The most obvious caveat of installing an SSD like this is that you will have to remove your Wi-Fi/Bluetooth card. You will have to make sure the antennas' connectors are somehow insulated so that they do not short-circuit anything once you put the system back together. To be able to connect to Wi-Fi networks with the original Wi-Fi adapter removed, you will need a USB Wi-Fi dongle, which are not as fast and trouble-free as their PCIe counterparts, and may be virtually useless under certain Linux distros.

In case something goes wrong, warranty may be difficult to claim, too, as is the case with many products from little-known Chinese brands.

With many ultra-budget Intel CPUs like the Celeron N4020, M.2 slots are limited to PCIe 2 speeds, which is 500 MB/s per lane; not any faster than a decent SATA III SSD. It makes little sense to buy an expensive PCIe 3 SSD for laptops and mini-PCs built around that kind of chips.

Pre-2012 machines are unlikely to sport full NVMe support meaning the SSD might work but will not be perceived as a bootable drive.
