MyDigitalSSD DDR2 Super Cache 32GB mSATA Solid State Drive Review

Specifications, Pricing and Availability




The MyDigitalSSD DDR2 Super Cache uses the 50mm mSATA format. This format is quickly being adapted across the consumer industry. Obviously the Super Cache part of the name refers to the drives ability to be paired with a spinner in a SSD cache array. The DDR2 part is much less obvious.


The MyDigitalSSD DDR2 Super Cache is the first mSATA drive to use Toshiba Toggle Mode flash. Toggle Mode flash is sometimes referred to as DDR since it transmits I/Os on both the rise and fall of the signal.


At this time the Super Cache is only available in 32GB capacity. This may change over time, but for now 32GB is all we have. This model has a claimed read speed of 270MB/s, right around the upper limits of SATA II. The write speed is rated at 110MB/s. Obviously the Super Cache isn't using a SandForce controller, but it doesn't have a SandForce price either. The controller used is a new model from Phison, a budget friendly controller manufacture based out of Taiwan with design and manufacturing backed by Toshiba.


To date we've seen a few mSATA drives and more are shipping this week. By a large margin the MyDigitalSSD DDRII Super Cache is the lowest priced model. It also has the best price per capacity model we've seen to date. At just $59.99 at MyDigitalDiscount, the drive has nearly twice the available user capacity of the Intel 311 Series and costs 40% less.


At the bottom of the specifications chart MDSSD lists several portable computers that support mSATA drives.
