Specifications, Pricing and Availability
The SanDisk Extreme II starts shipping today and in three capacity sizes - 120GB, 240GB and 480GB. Many of us would love to see a 960GB version, but SanDisk chose to leave a massive capacity size model off the table, at least for now. At the heart of Extreme II is a Marvell 88SS9187 controller with custom SanDisk firmware. Paired with the 9187 is SanDisk's 19nm MLC Toggle flash rated for 3K P/E cycles.
In a move designed to set a new standard, or to rebut the old ways, SanDisk used CrystalDiskMark to determine the marketing performance numbers. For years, ATTO and IOMeter was used to come up with marketing performance results, but over time companies moved away from the default ATTO tests (QD4), and IOMeter can be manipulated with compressible or incompressible results. To stop any confusion, SanDisk chose to use CDM for their marketing materials, since it's easy to run and a free application.
With that explanation out of the way, let's look at the specs. The 480GB Extreme II delivers 545MB/s sequential read performance and 500MB/s sequential write performance. IOPS performance comes in at 95K read and 75K write. The 240GB capacity size is the fastest in the Extreme II product family, but the 480GB model is only just behind. This is a sharp contrast to the original Extreme where the 480GB model had a sharp drop off in performance when compared to the 240GB model.
Each capacity size ships in two flavors, a Notebook version with a 7mm to 9.5mm adapter and a full Desktop Upgrade Kit with a desktop adapter bracket, SATA cable and mounting screws. Extreme II also has a five year warranty.
Just days before going live with the reviews, we received word about pricing. SanDisk's MSRP for the 120GB Extreme II is $129.99, 240GB is $229.99 and the 480GB is $439.99.
