After testing the SSD, HDD and Hybrid drives together, we felt it was time to test the powers of the SSD a little more.
We took two Kingston SSDnow v100 drives in a RAID-0 configuration and compared results of read/write benchmarks and file transfers from one drive to another.
Setup and Procedure:
A custom built PC with EVGA p55 LE motherboard, with intel core i5 processor running at 2.67 GHz and 6 GB of OZC Ram @ 533MHz. The RAID was setup using EVGA’s built-in RAID controller on the motherboard. A fresh install of Windows 7 was installed on the RAID-0 array and fully updated. Software was also installed onto the system including but not limited to:
- Photoshop Trial
- Office 2010
The RAID was benchmarked using ATTO’s Disk Benchmark. Two “Total Length” sizes were selected (256 MB and 2 GB) and each drive underwent two tests each for both file sizes or “Total Length”. Boot up times were measured using Microsoft’s SDK and using the “xbootmgr” command. Application start times were also measured using PassMark’s Application Startup Timer.
Finally, a 7 GB file was then ‘copied’ or replicated onto the same drive, thus employing simultaneous reads and writes. Times were ‘rudimentary’ calculated using an iPod stopwatch.
Drive benchmarks of the RAID looks like this (note in all figures, light blue represents RAID array setup, and black represents a single SSD):
Compared to a single drive:
You can see that the RAID produced more than double the rates. To further testing of read/write speeds I decided to test a ‘real world’ application. I took a folder that was roughly 7GB in size (all photos) and ‘copied’ the file onto the same drive in the same folder. This creates a whole new file onto the drive. Here are the time comparisons to fully copy the folder:
Copying with the RAID shaved off an entire minute! This is a pretty significant boost in speed.
Now for booting times which looked like this (smaller is better):
Again the RAID produced faster boot times in both areas. And now finally App start times (smaller is better):
Photoshop started in well under 2 seconds! Compared to the slightly more than 4 seconds on a single drive, this was a significant reduction in time.
So all in all, a RAID-0 configuration of SSD’s will dramatically increase speeds.
