After a number of makes an attempt, the quickest end result was simply over 4.5 GB/s, falling to simply beneath 4.0 GB/s after in regards to the 128 GB mark (the whole file switch was 173 GB, which was the whole measurement of the folder of enormous 7-zip archives I used to be copying). I believe the difficulty was the T700 within the M.2 slot on this Z690 board, though I had it set to Gen5 and verified that it was, in truth, working on the right hyperlink pace utilizing HWiNFO. The highest M.2 slot is meant to be PCIe 5.0, however I had higher outcomes utilizing a PCI-E 5.0 to M.2 adapter card within the high slot (I used to be utilizing processor graphics and nothing else was on PCI Categorical besides my boot drive on the underside M.2 slot).
This might get wordy, however I had quite a lot of points in testing these Gen5 drives, most likely all of which have been associated to my explicit check platforms. For instance, I usually current numerous charts with comparative sequential and random 4K outcomes at numerous queue depths, however I couldn’t produce constant outcomes with the T700 on my check platforms underneath customized workloads utilizing CrystalDiskMark, and that was on each the AMD X670E board and the Intel Z690 board. Normally, I simply set the benchmark to QD1, after which QD2, and so forth, however these outcomes have been very inconsistent from run to run, and I noticed a puzzling regression in efficiency at QD2 in comparison with QD1, amongst different issues.
Many efforts have been made to determine the easiest way to check this Gen5 SSD, together with shifting from the AMD AM5 platform again to a thirteenth Gen Intel platform, shifting from the Gen5 M.2 slot to a devoted PCIe 5.0 to M.2 adapter card within the PCI-E 5.0 x16 slot (which helped), and even attempting out the Micron storage driver rather than StorNVMe. Finally, the dearth of constant outcomes when making an attempt customized benchmark runs at numerous queue depths and threads stopping me from producing significant numbers wanted for an in-depth evaluate. Thus, that is only a “fast look”. (I additionally did not re-test the 2 T700 drives on AM5 utilizing bifurcation for the twin M.2 to Gen5 PCIe adapter – unsupported on the Z690 board.)
Backside line, storage is complicated, and I miss Allyn.
