Techman SSD XC100 Series NVMe SSD Review (3.2TB)

128KB SEQUENTIAL READ/WRITE

Sequential performance is measured similarly to the other two tests before. The drive is first secure erased to get it in a clean state. Next, we precondition the drive with a 128KB sequential write workload at QD256 until the drive is in a steady state. Finally, we cycle through QD1-256 for 5 minutes each for writes and then reads. All this is scripted to run with no breaks in between. The last hour of preconditioning, the average MB/s, and average latency for each QD is graphed below.

Sequential results are mostly well above the 1.4GB/s rating, however, we can see there are dips down to 900-950MB/s throughout. Latency averages in the low 20s as well.

The Techman XC100 is showing its dominance during the read tests. During sequential reads it outshines the test pool from QD 2-256 and reaches a high of 3180MB/s. Latency maintains under 2ms until QD32 and reaches a high of nearly 11ms at QD256.

In sequential write testing the XC100 is beat out by both the Intel and HGST, although, its performance of 1.5GB/s is very impressive still, especially considering it is rated for just 1.4GB/s.
