OCZ ARC 100 SSD Review (240GB) – Consistency in a Value SSD

CRYSTAL DISK BENCHMARK VER. 3.0 X64

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.

In Crystal Disk Mark we see a max of 433MB/s read and 429MB/s write. Both 4K reads and writes are very good. Typically, I wouldn’t expect to see such high 4K writes from a value drive so achieving 157MB/s is nice to see. 4K QD32 read is very low however at 74MB/s.

AS SSD BENCHMARK VER 1.7

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 result provided a Total Score of 1075; this is a very good score for a value drive. The OCZ ARC 100 reaches a max of 446MB/s and 410MB/s for sequential read and write tests.  4K results are also very good, though this time around 4K read didn’t break 30MB/s and write is just under 140MB/s. 4K-64Thrd reads are surprisingly high at 307MB/s, a startling contrast to the 74MB/s we saw in the high queue depth test in Crystal Disk Mark. In the IOPS we see it reaches a max of 78,474 read IOPS and 80,960 write IOPS. Both of which are above their rated values.

To complement this, the AS SSD Copy Bench presents us with transfer speeds in the mid 300MB/s range, while reaching a high of 388MB/s for the ISO test.

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.

Even in Anvil’s Storage Utilities, we see results similar to that of Crystal Disk Mark again for 4K, 30MB/s read and 148MB/s write. The max sequential read reaches 457MB/s and sequential write speed only reaches a high of 410MB/s.

With Anvil’s IOPS tests we see max IOPS for the drive coming in at over 80,000 for both read and write.
