OCZ RevoDrive 3 120GB SSD Review

3. Benchmarks - HDTachRW, HDTune Pro

Here is our testbed:

  • Motherboard: Foxconn Quantum Force Rattler P67 vP04 BIOS
  • Processor: Intel Core i5-2500K
  • Case: Open Air testbed
  • Power Supply Unit: Club 3D CSP-X1000CB 1000 Watt
  • Graphics card: Club3D Radeon HD 6790 CoolStream Edition
  • Memory: OCZ Gold PC3-10600 4x2GB 1333@CL9
  • HDD: WD 500GB 7200RPM
  • Monitor: LG L246WH-BH 24"
  • Windows 7 x64 SP1 with latest updates installed

For the tests, we used the following software:

  • HDTachRW v3.0.1.0
  • HD Tune v4.50 Pro
  • Crystal DiskMark v3
  • ATTO Disk Benchmark v2.46
  • ASS SSD Benchmark 1.5xxx
  • IOMeter v2006.07.27 with Xtreme Benchmark template
  • PCMark Professional edition v1.04
  • Anvil Storage Utilities 1.0.34. Beta 11

We start the tests with the HDTachRW software. It shows the potential read speed which you are likely to experience with the SSD. HD Tach is a low level hardware benchmark for random access read/write storage devices. The software measures the sequential read speed, the random access speed and sequential write speed.

HDTachRW reported an average sequential writing speed of 374.2 MB/s and an average sequential reading of 389.7 MB/s:

This is a decent performance for the drive. Have in mind that OCZ has tuned RevoDrive 3 to exhibit peak performance in a real world environment that uses a Queue Depth of 64 or 128, representative of applications continually moving data.

We move on to the HD Tune Pro software, another utility we used to measure the drive's reading performance. Although not necessarily representative of real-world workloads, HD Tune's targeted tests give us a glimpse of each drive's raw capabilities.

In the a sequential read test, the drive read the data at 292.3MB/s (average). The reported access time was 0.215ms:

In the corresponding writing test, the drive wrote the data sequentially on the disc at 212.7 MB/s (average):

The HD Tune numbers are a bit disappointing, although the average speed of the RevoDrive 3 is higher than other SSDs and a minimum write speed of 157.2 MB/s is still good.

Here is another sequential file test. The SSD's average performance for write was 740.350 MB/s and 836.508 MB/s for read , close to the performance numbers quoted by OCZ. For this test we used the "Zero" data pattern.

Selecting the "Random" data pattern had an impact to the drive's sequential read and write performance. This time we got just 150.626 MB/s average write and 386.162 MB/s read:

A "mixed" pattern improved the reading performance of the drive:

 

The HD Tune Pro also allows random read tests. Here are some more results with the software to randomly seeks files of different sizes. The random read performance is very high with file transfers of 1MB (648.271 MB/s average) , as well as with randomly selected file sizes:
