Version and / or Patch Used: 2.47
ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Sequential read transfers max out at 1.588 GB/s. Sequential write transfers max out at 1.261 GB/s.
We are seeing the same choppy synthetic performance that we saw in our previous Q Series Pro review. This choppy synthetic performance manifests itself only after the drive/array has been loaded up with data. The only review website you would ever see this particular performance information on is TweakTown.com, because we are the only review website to test with an OS Volume loaded up with data.
Toshiba Q Series Pro arrays deliver massive sequential read performance, with our Q Series Pro three-drive array outperforming both our Extreme II and 730 arrays.
Anvil Storage Utilities
Version and / or Patch Used: RC6
Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test, or just the read or write test, or you can run a single test (i.e. 4k QD16).
Anvil's is not so kind to our Q Series Pro arrays. This score is more like what we would typically see from a single drive.
Read IOPS through Queue Depth Scale
Anvil's read IOPS scaling is not choppy, but it's not too good either. Intel's 730 easily outperforms the Q Series Pro, and edges out the Extreme II to take the win in this test.
Write IOPS through Queue Scale
We are not entirely sure why the Q Series Pro falls on its face in this test, but it sure does fall on its face. We are seeing exactly the same thing we saw from a two-drive Q Series Pro array. When the Q Series is loaded up with data, it does not like synthetic testing; this is some sort of anomaly, because it rips through our real-world testing, delivering performance that is downright amazing.
Version and / or Patch Used: 3.0 Technical Preview
CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy.
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at 4 and 32.
Unlike what we saw with a two-drive Q series Pro array, our three-drive array delivers mostly good performance in this test.
Sequential 512K, and 4k QD 32 look good for any array; 4k and 4k QD4 are exactly what we expect from a Q Series Pro array. These two categories are low in comparison to the other two arrays on our chart. Toshiba's Q Series Pro seems to defy logic in that its 4k read performance is low, but its real-world performance is stunning.
4k write performance is looking excellent, and is what we would expect to see from a top performing array. Sequential write is a little on the low side, and 512k write is downright terrible, but as we have seen in the past, for some reason benchmarks like CDM do not accurately predict what we will get from a Q Series Pro array when we subject it to the testing that matters, real-world simulations.
Version and / or Patch Used: 1.7.4739.38088
AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic, as well as three practice tests. The synthetic tests are used to determine the sequential, and random read and write performance of the SSD.
For some unknown reason, AS SSD is our only synthetic test that agrees with Toshiba's Q Series Pro when it's loaded up with data and tested as it should be. Our three-drive Q Series Pro array delivers excellent performance, and it even manages to defeat one of our two contending arrays for the first time today. Next up is the important testing, and it's exactly what our Q Series Pro array has been waiting to sink its teeth into.
