Does this drive work with the 14? And is the 14 bus fast enough to support 7000Mb/s speeds, or is it better to save $$ and go with the non pro version’s 3500Mb/s speeds?
This is the specific one I have in mind:
Samsung 980 Pro MZ-V8P2T0BW 2 TB 7000/5100 MB/s M.2 PCIe 4.0 SSD
I think that your intuition is correct. If the Librem 14 has a i7-10710U processor that supports PCIe 3.0 where the drive has been designed for version 4.0, the bus could be limiting the speed by half. I think that if the bus speed is 4 GT/s, and the PCIe device has 4 lanes, for two read bits per lane, 8 bits per byte, that could come out to max 4000 MB/s. I could be wrong.
Yep, chipset for that CPU is PCIe 3.0 so not much point getting a PCIe 4.0 NVMe drive unless you are already thinking about future shuffling / upgrade of hardware.
As to whether it physically fits (as raised by @j_s) - due to the heatsink - that is valid question. However that particular module does not appear to have a heatsink. Right?
