OCZ Vector 256GB SSD
3. HDTachRW
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. The software measures the sequential read speed, the random access speed and sequential write speed.
The reported average sequential writing speed was 394.6 MB/s and the average sequential reading of 393.5 MB/s are lower than the figures quoted by OCZ and slightly lower than some other SSDs:
We move on to the HD Tune Pro software, another utility we used to measure the drive's reading and writing performances. Although not necessarily representative of real-world workloads, HD Tune's targeted tests give us a glimpse of each drive's raw capabilities.
The sequential reading test returned a 370.9 MB/s average speed. Writing was slower at 328.6 MB/s average:
