Accommodate M.2 22110 (Future Feature Suggestion)

Framework Laptop 16
#1

There are a lot of enterprise M.2 drives which have features not available to M.2 2280 form factor drives. I’ve searched high and low for one which has the features I’m looking for while having the shorter, more common 80 mm length, but they are non-existent.

To give examples:

  • Smart Modular DC4800
    • M.2 22110
    • TCG OPAL 2.0
    • T10 DIF/DIX
    • Variable sector sizes (512, 520, 4014, 4096, and 4160)
    • SR-IOV (15VF/PF)
    • Up to 256 namespaces
    • Zoned namespaces
    • Power loss protection
    • 1 DWPD over 5 years
  • Solid State Storage Technology Corporation EP7
    • M.2 22110
    • T10 DIF/DIX
    • Zoned namespaces
    • Power loss protection
    • 1.3 DWPD over 3 years
  • Fastro MS570
    • M.2 22110
    • TCG OPAL 2.0
    • T10 DIF/DIX
    • SR-IOV
    • 128 namespaces
    • Power loss protection
    • 27 DWPD over 5 years

I don’t really care about the SR-IOV or namespaces as those are overkill for a laptop. But the T10 DIF/DIX in combination with OPAL 2.0 would do wonders for data integrity and security (which are basic needs for a mobile professional), while not taxing the CPU like Bitlocker would (:low_battery::eyes:). The difference from a software-only solution like dm-integrity + dm-crypt is that the drive itself also verifies that the received data is correct, so errant data isn’t eagerly written, overriding good data, and not being discovered until the next time it and its checksum/hash is read—which could be a while later with the only good ephemeral copy of the data in RAM long gone; and that’s not a case which a backup would protect against.

I can’t get those features with plain old M.2 2280 SSDs. None exist on the market.

Of course, this would take a backseat to ECC RAM support. It’s the weakest link in reliability.

I haven’t seen a laptop support that size module ever. Now i could be wrong. But those modules supporting some of those features would require power that would cause battery life to be degraded. Most of those ssds are more for enterprise servers.

Edit: after more research the 1st one runs on 10-13v with up to 13watt usage the other 2 i imagine would be the same…where the sn850x is 3.3v 2a (~6 watt max)

Those are Enterprise drives for server and datacenter use. They’re not intended for laptops.

Why would you want that on a laptop? There is a permanently on battery to do this for you, so why buy a module that has its own backup power supply (and hence the extended length for the power supply (presumably a supercap) and the associated RAM) to do this for you?

As others have pointed out, this and other features you list are largely for server use.
