REPORT ANALYSIS AND FINAL THOUGHTS
When we undertook this analysis, we ultimately wanted to determine two things: First, we wanted to determine how the MyDigitalSSD SuperCache 2 mSATA 128GB SSD performed as a standalone SSD. Secondly, as it is being marketed primarily as a caching SSD, how does the SuperCache 2 perform in this regard? Does the FNet HybriDIsk software enable our Western Digital Caviar Green 1TB HDD to attain SSD-like performance?
We would like to give a tip of The SSD Review “Thank You” cap to MyDigitalSSD for providing the review sample and HybriDisk caching software license key.
As with most any “caching” SSD, the SuperCache 2 can also be used as a standalone SSD. With ATTO read speeds of up to 545.3 MB/s, the SuperCache 2 is more than competitive. Write speeds in the 331-363 MB/s range are little light compared to other 128GB mSATA SSD offerings, but are still acceptable. This could be a characteristic of the Phison PS3109 controller, which is only a 4-channel controller. It could be the result of a firmware implementation that is geared towards caching. At $99.00, which works out to a little over 77 cents per GB, the SuperCache 2 makes for a perfectly adequate mSATA SSD at a competitive price.
When it comes to the caching of our HDD to try to attain SSD-like performance, we are looking at three aspects — boot times, read performance, and write performance. With boot times of 16-19 total seconds being the equal of nearly any SSD, this performance improvement aspect of the SuperCache 2 / HybriDisk software / HDD combo is an unqualified success.
As far as read performance goes, all of our benchmarks of the SuperCache 2 / HyrbiDisk software / HDD combo showed read performance equaling that of many standalone SSDs. ATTO read performance that peaks at 542.9 MB/s is more than respectable for any SATAIII SSD.
Unfortunately, the SuperCache 2 / HybriDisk software / HDD combo did not achieve any write performance improvements whatsoever. Every one of our benchmarks showed this to be the case. The de facto consumer-level industry standard (and comparison basis) is NVELO’s Dataplex (now owned by Samsung) caching software. In typical applications, the Dataplex caching software significantly improves both read and write performance, along with boot times. At this point in time, the FNet HybriDisk caching software pales by comparison. Here’s hoping FNet can resolve this via a subsequent update or release version.
In conclusion, we have two grades to hand out today: One for the MyDigitalSSD SuperCache 2 mSATA 128GB SSD itself, and another for the FNet HybriDisk caching software.
MyDigitalSSD’s SuperCache 2 mSATA 128GB SSD is a competitive performer as a standalone SSD. It displayed excellent read performance, and adequate write performance. At a competitive price, it can be a good value purchase. The only real issues we had all appeared to be related to the HybriDisk caching software, and not with the SuperCache 2 mSATA SSD itself. The SuperCache 2 itself earns a passing grade.
The HybriDisk caching software is two steps out of three in the right direction. However, in order to be considered a complete caching solution, we need to see improvements in all three areas — boot times, read performance AND write performance. All three pieces of the caching puzzle are integral to its effectiveness. Anything less gets a grade of “incomplete”.
