MyDigitalSSD Super Cache 2 M.2 SSD Review – Exploring M.2 With and Without FNet HybriDisk Caching

If you are one of the millions of Lenovo, or other M.2 SSD contained portable laptop owners, this article may be of great benefit to you; that is if you are looking for both a performance and capacity upgrade to your present system.  Our expected report of the MyDigitalSSD Super Cache 2 M.2 SSD brought forward possibilities that even we never expected.  Quite frankly, enabling a dual installation (as we will discuss in the report) may have altered my thoughts on SSD caching just a bit, although not too much I can promise you.

Historically, all those who have followed along throughout our growth, know that I am not a supporter of SSD caching and that I am 100% pure SSD through and through.  The closest we have ever come to truly enjoying a caching solution was through our many reports on NVELO Dataplex, a solution that never really materialized once Samsung bought out NVELO.  To their credit though, the former NVELO Team, all of whom now are very happy Samsung employees, did a great job developing RAPID, a new caching utility that can be used in the Samsung 840 Pro and EVO series SSDs.


The MyDigitalSSD SC2 M.2 SSD is available in capacities of 32, 64 and 128GB and they can be found now at Amazon for $40, $60 and $100. This is great pricing considering this is a brand new form factor and MyDigital SSD is one of the first to mark availability for M.2.  It is a SATA 3 SSD and presently available in only the 42mm length (2242) which limits its capacity somewhat.  Performance is variable, depending on capacity, and listed at 530MB/s read and 410MB/s write for the 128GB capacity, 545MB/s read and 380MB/s write for the 64GB version, and 540MB/s read and 380MB/s write for the 32GB capacity.

Power rating for the SC2 is listed at .5W idle and .9W active with a three-year warranty and advanced attributes to include sudden power-off recovery, battery backup function, high and reliable ECC capability up to 24bits/sector, S.M.A.R.T features optimized for SSD, bit error monitoring and management, dynamic and static wear-leveling, dynamic bad block management, SMART commands and additional SSD monitoring.  Perhaps the most interesting thing about MyDigitalSSD Super Cache 2 SSDs though is that they include a free copy of FNet’s HybriDisk Caching solution.


Other than NVELO Dataplex, we have never recommended any caching solution as we found them to provide little or no visible benefit. Dataplex, on the other hand, simply used caching to increase the performance of the hard drive to that of the caching SSD, pulling the performance of a typical hard drive up as much as 5x.  By all claims, FNet HybriDisk does much the same and we aim to validate…or put to rest those claims in this report.  Something very special about HybriDisk, however, is the ability to control the size of the cache, enabling the remainder of the SSD as a logical drive, displaying pure SSD performance.


The MyDigitalSSD Super Cache 2 M.2 SSD is a 6Gbps SSD, driven by the Phison PS3109-S9 4 channel SATA 3 controller. and contains  two modules of Toshiba 19nm Toggle Mode NAND flash memory.

Size and value presently limit the capacity of this SSD as there are no systems available, as of yet, that accommodate any larger than a 2242 size M.2 SSD.  As well, pushing the two flash modules to that of 128GB each, would be very cost prohibitive.

We can also see below that the branding is not as straight forward as it we see most of the time.  Nevertheless, the product number on this memory still identifies what we need to know.


In addition to our Test Bench, we are going to be also using a Lenovo Y510 Ideapad for today’s analysis.  Although all Y510’s are not configured the same, this one contains the M.2 SSD connector and it connects to a SATA 3 Intel port.

Unlike other HP and Lenovo laptops that take a bit of ingenuity to get apart, the Y510 base simply pops off with the removal of 9 screws.
