MyDigitalSSD Super Cache 2 128GB M.2 SATA 6G SSD Review

When last we looked at the newest MyDigitalSSD M.2 SSD family, we posted a review of the MyDigitalSSD Super Cache 2 64GB SSD as a caching SSD and we tested it in the Lenovo Y510 with Hybridisk in use as the caching software.  We also have on hand the 128GB version of the SC2 which we are going to let stand on its own for testing today but we wanted to reiterate a great configuration we thought up while testing the Y510.

HybriDisk allows the partitioning of the SSD.  This means that, with this 128GB SC2 M.2 SSD we are testing today, once could create a pure SSD boot drive with a larger logical partition, leaving the remainder for HybriDisk use.  This enables the ideal solution for any SSD/HDD combo where we now have a full power SSD boot drive, with the large capacity hard drive getting close to the same speed through HybriDisk.


The MyDigitalSSD SC2 M.2 SSD is available in capacities of 32, 64 and 128GB, 128GB being the highest only because this M.2 form factor is presently 2242, which means it is 42mm in length and cannot fit additional memory modules.  The SC2 is a M.2 SATA 3 SSD and performance is variable but listed as 530MB/s read and 410MB/s write for the 128GB capacity.  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.


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.

The MyDigitalSSD SC2 128GB M.2 SSD contains the Phison PS3109-S9 four channel SATA 3 controller and contains only two modules of NAND flash memory.

The chosen memory for this SSD is Toshiba 19nm Toggle Mode NAND and each module is 64GB in RAW capacity.  Once the SSD is formatted, the total capacity available to the user is 119GB.

As much as many like to see testing in the ideal environment for that device, we always prefer the stay at home method of testing where we are sure we are getting the best scores possible.  We prefer our testing to remain unclouded by such things as pre-installed OS, bloatware, and general settings made to do nothing more but confirm compatibility with as large an audience as possible.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

There is not really a great deal of information available for the SC2, other than the fact that it is a SATA 3 new SSD and capable of TRIM.
