Quote:MyDigitalSSD Super Boot 2 (SB2) 42mm (2242) SATA III (6G) M.2 NGFF SSD Solid State Drive (512GB (480GB))


The NVMe adapter in our Pinebook Pros only supports PCIe type, (& NVMe). Ideally a M.2 with M key only would be used, (4 x PCIe lanes for maximum speed). Here is the description;

https://en.wikipedia.org/wiki/M.2#Form_f...and_keying

But, both B & M key PCIe NVMe SSDs can be used, as long as you understand the SATA & USB part won't work in a Pinebook Pro.

I thought I had read that only M keyed (excluding M + B) M.2 SSDs would work in the adapter, but can't find the reference anymore so I may have misread it.  Either way, thanks for the clarification.  I was wondering why the only 42mm SSD listed as working in the wiki was keyed B+M, and found this post while searching for the answer.  So the issue is not with the additional B key, but with the SATA interface.  Looking at Newegg, it appears that their filtering should make this easier.  You can select both the form factor (M.2 along with the size code) and the interface (PCI express), and that brings up the Sabrient drives and the Toshiba RC100.

I was looking for that as well, and couldn't find it even after consulting the user guide. On Monday I submitted a question on the power states to their presales department.  So far I only have an email acknowledging the question, but once I hear back I'll post the answer.


Another 42mm pcie drive that looks promising is the Lexar NM520 M.2 2242 256GB NVMe Solid-State Drive (LNM520-256RBNA).  From the description at Amazon:
  • Ideal for smaller notebooks
  • Upgrade from SATA to an entry-level PCIe NVMe performance
  • Faster speeds of up to 1650MB/s read and 1000MB/s write 1
  • Get 2. 5x the speed of a SATA-based SSD

Western Digital does make a M.2 NVMe line that has the same capacities in 30mm, 42mm & 80mm lengths.
These also have published power specifications, (reasonably good), unlike other brands.

Western Digital has another M.2 NMVe line, (only in 80mm lengths though), with good power specifications;

Hi Arwen!
I tried to upgrade my T440s with this SSD: WD SN520 NVMe 512 GB M.2 2242 PCI Express 3.0 x2. The motherboard do not recognize the SSD at all. It is recognize the SanDisk 64GB with windows 10. I tried to put the brand new WD SSD on an enclosuer and connect to 2 other pcs, and still not detected. I contacted the seller and he says it must works, so is it the quality of the WD SSD or it might be something else?

My opinion is that the SSD does not work, it's broken. If you bought it from a normal retailer, I'd return it and get a replacement.

Otherwise I have no kowlege of those particular WD SN520 SSDs. Those WD SSDs turned up in my NVMe search for devices with published power specifications. I've not yet bought one.

I'm still figuring out the NVMe interface (thank you for that link, btw), but in my searches I'm only finding drives matching the required specs that are 80mm. Is this the standard for NVMe PCIe?

If we can find them, using shorter drives would certainly help avoid the trackpad interference. I'm not having any issues, while typing this, and the incorrect drive is still inside. Has anyone found any that are 60 or 42mm?

@tophneal
    @wizard mentioned a few months back he had a 42mm PCIe SSD that worked, he said he was able to boot from it.
      Perhaps you could pull-up his post ...

I remember him posting that. I have a 42mm KingSpec that's arriving Tuesday. If it doesn't work, I'm going to start looking exclusively at those that have been confirmed working by multiple parties, instead of trying to contribute to finding new, working models.
