Crystal Disk Benchmark is used to measure read and write performance through sampling of random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.
Crystal Disk Mark shows off similar speeds as well. Sequential read reaches 2,443MB/s and writes reach 1,601MB/s. 4K reads and writes are very similar to the single drive. There is a noticeable increase in 512K results however, with double the write speeds for that file size.
The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance. For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.
Our AS SSD results reinforces our previous tests, but this time as usual speeds are a bit slower. The RAID 0 configuration was able to achieve a Total Score of 2419, nearly 1K more than a single SSD. Sequential read reached just over 2.4GB/s and write reached just over 1.25GB/s. Random IOPS have shot up to nearly double and 4K results are similar to that of a single SSD. We can also see that write access time has improved. The AS SSD Copy benchmark shows off some very wicked speeds, better than the results seen in our Samsung XP941 RAID 0 review.
ANVIL STORAGE UTILITIES PROFESSIONAL
Anvil’s Storage Utilities (ASU) are the most complete test bed available for the solid state drive today. The benchmark displays test results for, not only throughput but also, IOPS and Disk Access Times. Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and use in our benchmark testing.
Anvil Storage Utilities gives us a total score of nearly 9,700! This is a very impressive score and beats out any consumer RAID 0 config score we have seen in the past. Sequential speeds max at 2.4GB/s and 1.15GB/s read/write. 4K performance is similar to our other tests. We can see a high of 179K write IOPS, which is nearly 74K more than a single one of these SSDs.
Iometer is an I/O subsystem measurement and characterization tool for single and clustered systems. It was originally developed by the Intel Corporation however, they discontinued work on the program. In 2003 it was re-launched by an international group of individuals who are now continuously improving, porting and extend the product that is now widely used within the industry.
For our first test we are looking at how fast it goes during sequential reads and writes. By using a 30 second 128KB workload at QD32 we were able to max out sequential speeds. Overall, speeds are on par with what we have been seeing in our other tests. Sequential reads averaged at a little over 2.65GB/s and writes at just over 1.35GB/s.
Next we ran a 4KB random workload at QD64 for 30 seconds. We had to use a queue depth of 64 during testing in order to get the most IOPS out of these SSDs in RAID 0 as each SSD can support up to 32 queues. We see a great improvement here. Random read IOPS increased by over 86K and random write increased by almost 95K IOPS over a single SSD!
