Anvil's Storage Utilities:
Anvil's Storage Utilities is another new 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 S55'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 S55's performance was very similar to what we saw in our other tests. The drive was able to read at 488.12 MB/s and write at 362.4 MB/s.
The S55 wasn't one of the faster drives we've tested when it came to random reads and writes. In our tests, the drive was able to read at 114.49 MB/s and write at a 224.79 MB/s.
According to Silicon Power, the 240GB S55 is capable of up to 80,000 IOPS when writing 4K blocks. In our tests, the drive reached 29,309 random read IOPS and 57,545 random write IOPS. Increasing the queue depth had little impact on the S55's random write performance. However, with the queue depth set to 32, the drive was able to reach 37,391 random read IOPS.
