The Extreme 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 Extreme 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.
As I mentioned earlier, the Extreme II uses Marvell's 88SS9187 "Monet" controller. The 88SS9187 is powered by a dual-core Marvell 88FR102 V5 CPU and supports up to eight NAND flash channels. The controller also features a high-performance ECC engine with adaptive read and write scheme as well as on-chip RAID functionality.
For the 240GB version of the Extreme II, SanDisk opted to use their own 32GB 19nm eX2 ABL MLC Toggle NAND flash chips. Looking at the picture above, you can see that there are eight of these chips on the top of the PCB. The drive also has a 256MB Hynix H5TQ2G63DFR DDR3 memory chip that is used for caching.
