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.
Save for the sequential benchmark, where the Intel Optane SSD 900P dropped in just behind the Samsung drive, Intel's new Optane SSD 900P kicked some serious butt here. Access times are the best we've seen, burst rates are significantly better than everything else, and CPU utilization is nice and low. The Samsung NVMe driver seemed to put a larger than expected load on our host CPU in the Write test -- that doesn't happen with the Microsoft driver, however.
