So I am slowly upgrading my TrueNAS.
Stage 1 was new PWM fans and extra ECC RAM.
Can I get a sanity check in Stage 2 please? I was thinking of adding a PCIe expansion card for M.2 SATA drives before swapping out the remaining drives.
The heart of the system is the ASRock Rack C2750D4I.
It has the Atom processor bug fix. Manual says PCIe slot is Gen2 x8. It has been running with x6 consumer grade HDDs for years which I got out of bin at work.
I want to go all SSD (Stage 3) for speed, lower power, quieter operation (it is by far the loudest thing in my little computer cave) and just because.
I also want to experiment with using it as a VM host. Probably not running the VMs on it directly but from a hypervisor over software iSCSI.
So one of these M.2 SATA expansion cards should suit. Supports two 2280 length M.2 SATA SSDs.
PCIe 2.0 x8 - Max throughput of up to 4GB/s (or 32Gb/s) right?
Add two of the following drives.
SATA 3.0 each drive max transfer speed is 6Gb/s
So the question is the drives cannot saturate the PCIe interface, correct?
