HD Tune Pro - Sequential Performance
Version and / or Patch Used: 5.50
We measure sequential performance with 64K data and read across the entire user LBA range. The numbers are not as high as the 128K and above sequential test numbers but we show the 128K QD1 performance after a number of sequential and random writes further down the page.
There are only two other native PCIe M.2 products on the market today. The Samsung XP941 and Plextor's M6e products. Plextor has the original M6e and the new M6e Black Edition parts, both represented on the chart today.
The M6e and XP941 take a back seat today though, this is about the amazing performance of the SM951 and amazing is exactly what it is. The average sequential read performance is twice that of the M6e products in most capacity sizes.
The SM951 posts nearly three times the sequential write performance of the M6e drives and gets very close to doubling the sequential write performance of the XP941 it replaces.
HD Tach - Sequential Write Performance after Random Writes
Version and / or Patch Used: 18.104.22.168
After a number of sequential and random writes, we tested the SM951 512GB in HD Tach. This software measures sequential performance at 128K at QD1. The read and write performance both remain high.
