MyDigitalSSD BP4 240GB SSD
Here we get our first look at the MyDigitalSSD BP4. These drives are so new they shipped without a label and we later received the sticker just prior to the review. I'm sure MDSSD will do a much better job at getting the label strait, something I could use some practice doing.
There really isn't much to see on the outside since SSDs are all about the internal components.
This is MDSSD's first 7mm z-height drive. We knew it wouldn't be too long for a 7mm drive to enter the lineup since MDSSD focuses on the mobile market with a keen eye for new technology that reduces the cost of ownership.
Here we get our first look at the internals. The Phison S8 controller was in the BP3, but the new programming and firmware make the updated version faster across the board.
We weren't able to find a lot of information on the DRAM chip. PSC (Powerchip Semiconductor Corp) and Elpida Memory announced a joint venture in Dec 2011 and since then it's been a bit difficult to find all of the fine details. We're told this is a 256MB chip.
This drive uses eight of the new Toshiba Toggle 2 NAND chips built on the new second gen 19nm process. The new 16K page size increases sequential performance... as you're about to see.
