3. HDTachRW, HD Tune Pro
Here is our testbed:
- Shuttle SH81R4
- Processor: Intel i7 4790
- Graphics card: Club3D Radeon HD 6790 CoolStream Edition
- Memory: 2x8GB RAM DDR3-1600 Crucial
- SSD: 512GB Crucial MX100
- Monitor: LG L246WH-BH 24"
- Windows 7 x64 SP1 with latest updates installed
For the tests, we used the following software:
- HDTachRW v220.127.116.11
- 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
The HDTachRW software you see in the first screenshot below measures the sequential read speed, the random access speed and sequential write speed of the BX100 SSD. Both read and write graphs look steady for the complete capacity of the drive. The average read speed was 401.7 MB/s and the corresponding speed for write was 328.5 MB/s.
Obviously, in real world client scenarios it is unlikely that one would constantly write to the drive like HD Tach does.
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 BX100 SSD read the data sequentially at 374.2 MB/s (average). The access time was low at 0.12 msec:
As you see in the screenshot below, the writing speed was not very stable after the 650GB mark of the graph. That had a small impact to the overall average writing speed of the drive, which was logged at 306.1 MB/s.
