Specifications, Pricing and Availability




At the time of writing MyDigitalSSD is focusing on two capacity sizes in the 2.5" form factor - 120GB and 240GB. 64GB and 512GB are an option that we may see at a later data. Yesterday we published our review of the 240GB model and today we have the 120GB in the spotlight.


The BP4 120GB is rated for 555MB/s sequential reads and 470MB/s sequential writes. Random performance tops 47K IOPS read and 78K IOPS write. Not shown on the specs image is where the IOPS are delivered, BP4 has very impressive low queue depth read IOPS performance, the QD2 read measures at just over 40K in our tests, superior to OCZ's Vector, Samsung's 840 Pro and my own SSD, the MDDSSD TweakTown Chris Ramseyer Signature Edition SLC by SuperSSpeed.


The measurement was taken with compressible data and that is important to note in this review. The controller is from Phison, but it works with compressible data faster than incompressible data, just like LSI SandForce's controllers.


MyDigitalSSD backs the new BP4 series with a three year warranty, which is average for a mainstream product. The current price of $99.99 puts this drive in the lower end of the mainstream SSD segment; it borders on budget SSD prices actually.
