The Ultra II comes in a small, red and gray box. While there aren't a lot of details on the back, the front of the box advertises the drive's key features including its 240GB capacity and maximum read and write speeds. Inside, you'll find the SSD, a mounting spacer for use with traditional 9.5mm drive bays, and a fold out guide that contains warranty information as well as installation instructions for both desktop and notebook computers.
Physical Features:
The Ultra II looks very similar to SanDisk's other 2.5-inch SSDs. The top of the outer casing is made out of black plastic with a large, black and red sticker showing that the SSD is part of the company's Ultra II series. The bottom of the casing is made out of metal and is painted black to match the top. The large sticker on the bottom covers the screws holding the drive together and shows information like the part number, capacity and serial number.
Upon opening the case, I was a bit surprised to see how small the Ultra II's PCB was. Instead of using a regular size PCB, SanDisk has placed a half-slim SATA SSD inside of a 2.5" case.
The 240GB version of the Ultra II uses Marvell's 88SS9190 controller. There is very little information available regarding this controller but from what we can gather, it is very similar to the 88SS9189 controller found in Crucial's M550 and MX100 SSDs. The biggest difference is that instead of eight NAND flash channels, the 88SS9190 supports only four.
For the 240GB version of the Ultra II, SanDisk opted to use their own 1Ynm X3 ABL Toggle NAND flash. Looking at the picture above, you can see that there are two 64GB NAND flash packages on either side of the PCB. The drive also has a 256MB Micron DDR3 SDRAM memory chip that is used for caching.
