CRYSTAL DISKMARK 3.0.1
Crystal Diskmark is a very flexible benchmark that shows the speed of the drives at various file sizes. All of the smaller file sizes are measured in random access, a key weak point of many types of Hard Disk Drives. With this benchmark we can see the great scaling from the single drive compared to the raid array. The scaling in the random access also shows some great gains in speed, which is very beneficial from a typical user pattern in an operating system environment.
HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible. This will help to negate as much cache results as possible.
The first two results are from the ‘Short’ test mode. As you can see the single drive has an average of 110.4 MB/s compared to 241.2 MB/s for the raid array.
For the Burst Speed, you can see that the array is much higher out of the gate, with 245.1 MB/s for the single device being completely outran by the 413.6 MB/s for the array.
