    Is StorageSpace smart enough to take advantage of PLP in SSD? For this to work, software has to know how to safely transfer data from cache to disk and that's not straightforward.

    When used as a cache drive fronting a virtual drive with parity, it ONLY works when the drive supports PLP: Solid-state drives must provide power-loss protection.

    Looks like it comes in a dell caddy as well, are they cross compatible (assuming the backplane supports U.2)?

    Can you use this for booting with an adapter like this one from startech?
    U.2 to PCIe Adapter for 2.5

    According to startech this doesn't require any drivers, but I know nvme booting does require bios support in many cases.

    Write speed is slow for this drive. Isn't that what you don't want for a cache drive?

    Yeah, this wouldn’t change the capabilities of NVMe booting, which as you already noted is determined by the BIOS. Generally speaking, you need you need a hacked BIOS (Good luck) or a more recent motherboard than the v1/v2 Xeons. It doesn’t matter if NVMe is cabled (U.2) or slotted (M.2 or PCIe), booting is the same.

    It’s not fast enough for wire speed at 10gbps, yes. But if you have a gigabit network (Or multi-gigabit up to 5gbps), or otherwise need faster local access (VMs, etc) this is more than enough.

    Well crap, you got me there. Double the IOPS and double the sequential writes.

    A mod can close this now. :oops:

    100% life on both of them, with ~750GB reads/writes for each (I'm doing a badblocks run, which is why it's now higher).

    42 power-on hours, with 18 power cycles, 15 of which were unsafe!

    Anyways, they seem basically brand new.
