HD Tune Pro - Sequential Performance
Version and / or Patch Used: 4.00
The top three drives in our chart today are all LSI SandForce SF-2281 based RAID products. I like to call these All-in-One (AIO) SSD RAID products because the RAID controller and SSDs are all on one card.
In this test, we read from the entire user LBA span of the drive at a queue depth of 1 (QD1). This isn't the ideal situation for AIO drives because it's a fairly light workload, but it's what you encounter with consumer type workloads.
The sequential write test uses the same parameters, but here we see a large improvement in most cases over the list of consumer SSDs in the chart. That means even under a light write workload, the RevoDrive 350 outperforms run-of-the-mill 2.5-inch SSDs.
HD Tach - Sequential Write Performance after Random Writes
Version and / or Patch Used: 4.60
Again with QD1, we test sequential reads and writes, this time on the same graph. This test takes place after a limited number of random writes to the RevoDrive 350. With some products, we see the write performance drop to very low levels, but the RevoDrive 350 480GB does very well and delivers fairly consistent low queue depth performance.
