SanDisk Ultra II 240GB SSD

Here we get our first look at the Ultra II SSD. Our drive arrived in a special reviewer package, so we don't have the retail box this round, but should receive the full retail kit in the other capacity sizes. The only accessory in the retail package is a 7mm to 9.5mm adapter.

The model number, serial number and capacity size are listed on the back of the drive.

SanDisk used a 7mm case design for the Ultra II so this model will work in new Ultrabook designs that require the smaller form factor.

Inside we found a tiny PCB with one controller, one DRAM buffer and four NAND flash packages. Half of the case is plastic and the other half is metal. The controller faces the metal side and a thermal transfer strip covers all of the components on this side.

The thermal material is oily and that makes it difficult to see the markings on this side without zooming in.

The controller is a Marvell 88SS9190-BJM2, a 4-channel controller.

The DRAM is from SK Hynix, model H6TC2G63FFR.

Our first close up look at the SanDisk 1Ynm ABL X3 NAND package.

The two remaining flash packages are on the other side of the PCB.
