SUPERTALENT DRAM DISK PERFORMANCE
The funny thing about the speed of memory is cornering an exact number on performance is almost impossible, a GB/s transfer gained or lost can occur at anytime. Super Talent specifications list their testing at over 5GB/s speeds where we get 10GB/s from the same software. Our having 32GB of memory available did allow a larger Dram Disk though which might have increased transfer speeds.
We had originally discounted the validity of ATTO as the pattern we were seeing just didn’t seem right. The numbers were all over the place:
Next up, we tried things out with Quick Bench and the things seemed a bit more stable:
We couldn’t resist the opportunity to put the Dram Disk through its paces in PCMark Vantage as well. To say that these are the best results we ever obtained is an understatement.
In the end, the only method of analysis we could rely on for performance testing was moving a 1080P HD 2.5GB movie from one spot on the Dram Disk to another; we were wrong. The movie copied and transferred so fast that the normal copying screen never even appeared; it had to be complete in 10th’s of a second. It was at this point that we realized that the 32GB version would have been much more effective for larger file transfer than our 8GB drive.
