Anvil's Storage Utilities:
Anvil's Storage Utilities is another benchmark designed with SSDs in mind. The standard storage benchmark measures a drive's performance by testing its transfer speeds, access times and IOPS.
Iometer:
Lastly, I ran a series of tests using Iometer. This tool can be configured to benchmark a number of things. In this case, I used it to measure the US70's read and write speeds and the number of operations per second. The tests were run using random bytes and a queue depth of 3.
The US70's performance was very similar to what we saw in our other tests. The drive was able to read at 4784.36 MB/s and write at 4074.88 MB/s.
The US70's random read and write performance was hit and miss when tested with Iometer. While the drive was able to read at a respectable 329.82 MB/s, its write speed averaged out at only 552.12 MB/s.
Silicon Power really doesn't say what the US70 is capable of in regards to IOPS. In our tests, the drive reached 84,434 random read IOPS and 141,343 random write IOPS.
As with most drives, the US70 performed better with more threads and at higher queue depths. With eight threads and the queue depth set to 32, it reached 514,061 random read IOPS and 439,074 random write IOPS.
