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 Ultra Plus' 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 Ultra Plus' performance was very similar to what we saw in our other tests. The drive was able to read at 510.22 MB/s and write at 424.31 MB/s.
The Ultra Plus' random read and write performance was hit and miss. While the drive was able to read at a respectable 154.13 MB/s, its random write speed topped out at only 152.69 MB/s.
According to Sandisk, the Ultra Plus is capable of 82,000 IOPS when reading and 39,000 IOPS when writing 4K blocks. In our tests, the drive reached 39,457 random read IOPS and 39,039 random write IOPS. Increasing the queue depth had little impact on the Ultra Plus' random write performance. However, with the queue depth set to 32, the drive was able to reach 81,577 random read IOPS.
