Sandy Bridge Testing – Crystal Disk Mark
Similar to AS SSD, Crystal Disk Mark uses a similar method of testing storage. Its mostly an example of small files with little to no usage of disk queuing.

Baseline Comparison for Raid 0
| Raid Controller | Onboard Intel |
| Drives | Intel 330 60GB SSD x 2 |
| Raid Level | Raid 0 |
| Stripe Size | 256KB |
As a baseline you can see the bulk of the performance from the pair of drives, is seen in the read category.
| Raid controller | LSI MegaRAID 9271-8i |
| Drives | Intel 330 60GB SSD x2 |
| Raid Level | Raid 0 |
| Stripe Size | 256KB |
The sequential reads pickup around 90MB/s over the baseline, the write performance is almost the same at around a 1MB/s difference. The 512K read performance shows double that of the baseline. The 512K write performance shows a 75MB/s increase in performance as well. Move on to the 4K the read performance is 40MB/s higher than the baseline. However the write performance drops off 28MB/s. The trend follows in the 4k QD32 results, with write performance picking up 100MB/s, and the write performance decreasing by 5MB/s.

Moving on to a five drive array. We see an overall performance increase in all tests. Except for the 4k Write, which falls 7MB/s from the two drive array, and 36MB/s from the baseline.
Summary Of Crystal Disk Mark On Sandy Bridge i7 Test Setup
Overall we see less fluctuation on this benchmark than on the previous AS SSD benchmark. Bus saturation plays almost no part in the 4K write performance. As the bus at this point doesn’t have enough data flowing through it come into play.
