ASUS Zenbook SSD Review – Not Necessarily SandForce Driven Hits A Speed Bump

AS SSD BENCHMARK VER 1.64

Up until recently, AS SSD was the only benchmark created specifically for SSD testing and it uses incompressible data which is favored by many SSD enthusiasts.  Once again, the AData XM11 results are on the left with the Sandisk U100 on the right:

Significant difference in the disk access time became apparent here which, accompanied by the low 4k random write results, could account for a visible performance result in comparing the systems side by side.

Even a close look at the IOPS displayed a significant drop in performance.  This is also a good opportunity to reflect upon the ‘SandForce Driven’ SSD being 120GB, or 111GB after formatting, while the 128GB Sandisk is 119GB after formatting.

AS SSD COPY BENCH

The AS SSD Copy Bench determines the transfer speed and time that it takes for each SSD to move a file that matched that of an ISO, program and game. It is very straight forward and an excellent way to compare SSDs in a ‘true to life’ scenario.

I can attest to the fact that the Sandisk U100 took a great deal longer than the XM11 as I thought something had gone wrong and the system had frozen.  The 47 second transfer time is reminiscent of a hard drive.

ANVIL STORAGE UTILITIES PROFESSIONAL

Over the last little while, we have been assisting with beta testing new benchmark software called Anvil Storage Utilities which is an absolutely amazing SSD benchmarking utility.  Not only does it have a preset SSD benchmark, but also, it has included such things as endurance testing and threaded I/O read, write and mixed tests, all of which are very simple to understand and utilize in our benchmark testing.

SANDISK U100

There are just so many performance ‘hiccups’ that separate these drives that we could go on at much greater length if we needed to.  The easiest method, of course, is simply to look at the final score totals but, if you must, take a look at the access speed differences (resp. time), IOPS as well as the transfer speeds.  The AData XM11 reached 82,000 IOPS at 4K QD16, 30 times more than the Sandisk. Lets take a closer look at the XM11’s components:
