The MyDigitalSSD BP3 and its Phison S8 controller was the sleeper SSD product of 2012. The BP3 was a very fast mainstream drive with a price that blended into the budget SSD class. BP3 used a Phison S8 controller, a controller that was a break out product for Phison, blowing the capacitors off every other Phison controller before it. Phison has made further refinements to the controller to increase performance, mainly in the random area, the one place where this series needed improvement.
The MyDigitalSSD BP4 uses the newly refined S8 controller and pairs it with the newest in NAND flash technology. Toshiba released 19nm Toggle 2 NAND last year and a few products took advantage of the technology. The most well-known product was Plextor's M5 Pro, but BP3 used it as well. The new version, version B, doubles the page size to 16K. This increases sequential performance and the new Toggle 2 version B also costs less than the first 19nm.
Lower prices and new cutting edge technology, it sounds like something My Digital would latch on to and bring to market before anyone else. The BP4 2.5" drives are here in the lab, but not listed at Amazon just yet.
My Digital does have the BP4 mSATA drives listed and we'll take a look at those next week. For now, let's check out what could be a nice price to performance vs. capacity leader.
