Would you buy HPE 866844-B21(SATA) or HPE 862159-B21(PCIe)?

Thanks in advance

If your budget allows, and you care about speed, the PCIe is the way to go ... period.   The SATA-attached device is constrained by the SATA bus speed, while PCIe is constrained by the PCI bus.  It isn't even a close contest.

What are you intending to put them in? The part numbers come up as part of project moonshot and if it's really for that then it would be unlikely you would ask at EE. As dlethe says PCIe is faster than SATA but there again you have to have somewhere to put them so to use PCIe in the hotswap bays of a ProLiant there's a lot of messing about with the enablement kit whereas SATA ones plug straight in.

Definitely the NVMe drives then. They're not boot devices but there's room for the 120GB SATA one to boot from as well. Only thing is though do you need any local storage at all for remote desktop servers or is it just for booting the OS?

I just ordered the PCIe... they told me they support boot? (On UEFI and Server 2016)

From HPE: ).
NOTE: SATA and NVMe M.2 SSDs can both be used as an OS boot drive....
Cool. Quickspecs must be out of date.
