Fujitsu Quadro-M Series PCIe SSD Preview (Page 4)

HD Tune Pro - Sequential Performance

Version and / or Patch Used: 5.50


RAID benefits greatly from more than one IO request at a time. One issue we've found on many of the All-in-One RAID products is single queue depth read or write performance suffers compared to a single SSD in very low queue depths. Here we read across the entire user LBA span at QD1 in 64KB sequential blocks. The Fujitsu Quadro-M delivers an average sequential read performance of 348 MB/s. Later in this review, we'll test the drive at higher queue depths, and the performance will increase significantly.


In this test, we swap the reads for writes, again going over the entire user LBA range. We had an average score of 328 MB/s, but the peak performance topped 511 MB/s.

HD Tach - Sequential Write Performance after Random Writes

Version and / or Patch Used:


After a number of sequential and random writes to the drive to start the garbage collection process, we tested it again, this time with HD Tach to measure real-world sequential performance. The Fujitsu Quadro-M 480GB walked away with an average sequential read of 368 MB/s, and the sequential write was 341 MB/s.

More importantly, the drive didn't have many large performance drops when writing data. The lowest we scored was just over 200 MB/s. It's common to see drops that get under 100 MB/s with some consumer SSDs, and value-class models can dip well below that.
