EFD Software's HD Tune is described on the company's web site as such: "HD Tune is a hard disk utility with many functions. It can be used to measure the drive's performance, scan for errors, check the health status (S.M.A.R.T.), securely erase all data and much more." The latest version of the benchmark added temperature statistics and improved support for SSDs, among a few other updates and fixes.
HD Tune reveals excellent average read speeds for both 5100 Series drives, again paired very closely with each other. The write speeds, however, are very middle of the road and are outshined by both the Samsung 850 EVO
and 750 EVO drives
, while trading with the Crucial M550
and WD Blue. This write trend is also seen in the burst test, though interestingly both 5100 Series drives deliver bottom tier burst read performance. This is likely due to the poor small transfer size results we observed in ATTO.
To the positive, both access latency and CPU usage are excellent for the 5100 ECO and MAX. This bodes well for datacenter
usage where access times can make or break a critical application. Consumers are less likely to be impacted by less than stellar access latency, though it is still important.
