Error Scan: scans the surface for errors

Temperature display

HD Tune Pro gives us accurate read, write and access time results and for the last couple of years has been gaining popularity amongst reviewers. It is now considered a must have application for storage device testing.


We quickly learned that the Indilinx Infused Everest II platform is unlike anything we've seen before with the Vertex 4. Both the V4 and A4 limit QD1 read performance to much less than the advertised peak performance. The Vertex 4 when released only produced around 200MB/s sequential read with a single request, but that was later increased to around 300MB/s with firmware updates.

The Agility 4 produces around 170MB/s sequential read performance with a single request. If you do a lot of file transfers one at a time, this is not the drive for you. Moving a single large lot of movies, photos, audio files or for that matter any file transfer where you select your files then copy/cut and paste will result in a single transfer at just roughly 170MB/s or less.


Writing files to the drive is a different story. Here we see a sequential write speed that averages 383MB/s. Both the Vertex 4 and Agility 4 have a massive dip at roughly 70% through the test. This dip has been there since we first started looking at the Everest II platform. That dip is where the minimum speed comes from.
