Within the Full System Drive benchmark with an empty drive, the UD90 managed common bandwidth of 391.53 MB/s, with common entry time of 70 μs (microseconds). Stuffed to 50% capability, the efficiency dropped a bit to 332.64 MB/s common bandwidth and 83 μs common entry time. As end-users have a tendency to not use empty drives, all benchmarks to observe present outcomes with the drive crammed to the identical 50% capability.
However first, a phrase on the comparability charts to observe. I’ve not examined “low-end” PCIe Gen4 drives thus far, and placing this (at present) $62 drive up towards the likes of a Samsung 990 PRO appears ridiculous. Sooner or later there might be a extra affordable roundup of reasonably priced drives, so please ignore the huge pricing gulf for now.
First, let’s check out random 4K reads and writes utilizing CrystalDiskMark, at queue depths of 1, 2, 4, and eight (all single-thread):
