Synology SNV3400-400G 400GB SSD Review

The official 4K random write figure of 40,000 IOPS came with the drive tested at a queue depth of 256. We test at a lot shallower queue depths so our results are a good deal higher than the official one. The best we saw from the drive was 104,189 IOPS at a queue depth of 8.
