Testing and Benchmarks (continued)
SiSoft Sandra Disk Performance Test
In this test, on the vertical scale, lower scores are best; on the horizontal scale higher scores are the best. Notice that the array in question is the red marker, the farthest right and the lowest vertically: the best darned array in the whole competition by a long shot. With a sustained transfer rate of about 190 MB/sec this card is kicking ass and taking names. The place where it really stands apart is access times, with a record shattering 2ms average latency. Now that is blazing fast~! Lets look at a few more tests before I draw my conclusions... however with numbers like this, the conclusions should be becoming obvious.
SiSoft Sandra Disk Read Test
This test records the read speed over the entire length of the drive. Obviously, higher is better and once again my array is the red marker. We can see that not only does the card perform exactly to manufacturer specification, it also surpasses all of the other drives in the database. Simply amazing performance!
RAID 0 Testing
For the sake of comparison with other controller cards that I have tested on this site, I tested this controller in a RAID 0 configuration. Typically, RAID 0 is used when sheer speed is more important than the data itself. A good example of when to use a RAID 0 is when you are doing video editing, gaming, or have the desire to access data very quickly and need a place to store the files and programs.
Please note that for the following tests, the array was configured as a 4 disk RAID0 array!
CrystalDiskMark 2.1
You can see that the top read speed is very good, over 300MB/sec as compared to 210 MB/sec in the RAID 5 configuration. The write speed is nearly 250MB/sec, a huge improvement over the 75 MB/sec that we saw in the RAID 5 configuration.
Datamarck 0.0.4
The Datamarck tool is used to show you the general performance characteristics throughout the entire drive. We can see that overall, performance ranged from 73 MB/sec to 150 MB/sec, with a mean speed of approximately 126 MB/sec. Because of the way that Datamarck accesses the hard disk, the throughput results are typically a little lower than CrystalDiskmark. A key number to notice is the latency or disk access time.
HDTune 2.55
HDTune is another good tool that gives an idea of how the drive will perform over its entire length. As we can see, the read rate is quite decent, and fairly stable across the entire drive. An uneven read rate is a sign of a controller that does not handle cache requests nicely. You will also notice that the latency is both low and stable. The top-end read speed of 200MB/sec is quite good when you compare it to the 170MB/sec that the RAID 5 configuration had. Lets take a look at those Sandra tests!
