![]() ![]() When possible, we also log the temperature of the drive via the S.M.A.R.T. We tossed in this one last test to measure the performance of the drive over a 15-minute window. ![]() ![]() Write speed and temperature are two important and inter-related metrics for external devices. And, scaling out to a QD of 4 or even 128 doesn’t improve performance much, but rather just exaggerates latency. This results in an IOPS throughput of 113 IOPS read and 286 IOPS write, which is just a fraction of what something like the SanDisk Extreme or other SSDs are capable of. Seagate’s Backup Plus Ultra Touch boasts random read latency that comes in at ~8.8ms read and 3.5ms write. During sequential transfers, performance peaked out at 132MBps read/write. On average, Seagate’s Backup Plus Ultra Touch ranks last overall. ![]()
