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 850 EVO'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 1TB EVO 850's performance was very similar to what we saw in our other tests. The drive was able to read at 528.24 MB/s and write at 510.47 MB/s. With RAPID mode enabled, its read and write speeds jumped to 591.25 MB/s and 847.78 MB/s, respectively.
The 1TB 850 EVO also performed very well when doing random reads and writes. In our tests, the drive was able to read at 150.32 MB/s and write at 347.87 MB/s. This by itself is impressive, but with RAPID mode enabled, its random write speed jumped to 395.55 MB/s.
According to Samsung, the 1TB 850 EVO is capable of 98,000 IOPS when reading and 90,000 IOPS when writing 4K blocks. In our tests, the drive reached 38,481 random read IOPS and 89,054 random write IOPS. RAPID mode had little impact on the 850 EVO's random read performance. However, with it enabled, the drive was able to reach 101,260 random write IOPS.
