AMCC Storage 3ware 9690SA SAS/SATA RAID Controller
Test Results (continued)
These graphs are a little tougher to read and understand, but I'll do my best to interpret them for you. What these surfaces represent is the performance parameters of the controller card under a variety of IO situations. Higher values are better here. In the read performance test, we will see how quickly the controller card can get data from the disk to the bus. On average, the read speed was approximately 1.2GB/s; those numbers are stunning! Mind you, most of the file sizes tested were well within the size of the cache of the controller card and thus this does not take into account the actual disk access times. Server 2008 dominates in this series of tests, as a true server platform should.
IoZone 3 Write Test
| Windows Vista Ultimate Service Pack 1 |
Windows Server 2008 |
 |
 |
In the Write test, the average write speed is just over 683MB/s. Once again, the performance of this card is blowing me away.
IoZone 3 Random Read Test
| Windows Vista Ultimate Service Pack 1 |
Windows Server 2008 |
 |
 |
The random read test attempts to defeat the cache by reading from locations all over the drive. The performance that these graphs show is just phenomenal! The average random read speed is 1.0GB/s!
IoZone 3 Random Write Test
| Windows Vista Ultimate Service Pack 1 |
Windows Server 2008 |
 |
 |
The random write test attempts to defeat the cache by reading from locations all over the drive. As is typical of this test suite, the writes are slower than the reads, the average being about 650MB/s. One interesting thing to note is that larger writes perform better. A good rule to remember!
