One of only three drives to date featuring emulated SLC technology, SanDisk's Extreme II is a Hyper-Class SSD geared toward the enthusiast crowd.

SanDisk's latest flagship SSD. Is it among the best?
Storage
The SSD market as many people know it is inundated with drives that have one of LSI's SandForce SF-2281 controllers at their heart and whilst this is not a bad thing - given that they have proven reliability and some of the best performance to be had, they are not without their faults.
SSD owners today, use their drives for a multitude of tasks and breaking these tasks down to the way the drives see the data, we have two data types; compressible and incompressible. SandForce based drives typically use lossless data compression to minimise the write cycles to the flash in order to prolong its life span, however not all data sets can be compressed in this way and consequently when these controllers meet this type of data, the write speeds consequently slow down as the data takes more time to process.
SanDisk's Extreme series of drives as we have here today, are now on to their second generation and following the success of the original Extreme that was based around the SF-2281 controller, SanDisk want to take the performance up a notch to give this drive a huge selling point against every other drive out there. To do this, the SandForce controller had to be laid to rest as the way it handles incompressible data was not going to be right for an 'extreme' drive. As a result, Marvell has been brought in with its top end controller and this teamed with SanDisk's own 19nm Toggle NAND MLC flash and a 256MB cache is what is set to give this drive the grunt it needs to push it to the top of the SSD performance charts.

This is why today we’ll be reviewing the SanDisk Extreme II 240GB, which is SanDisk’s latest high performance SSD offering for the consumer market. Like a number of other SSDs on the market, the Extreme II will come in capacities of 120GB, 240GB, and 480GB. Looking at the capacities, you’re probably thinking “Oh, no! Another vanilla SandForce drive!”, but it’s actually not...

Today we are looking at the latest high speed Solid State drive from Sandisk, the Extreme II. This follows on from our review of the Ultra Plus 256GB Solid State drive which we reviewed back in March this year. The previous generation SanDisk Extreme adopted a SandForce controller however the latest Extreme II model has the Marvell 88SS9187 controller onboard. Is this a drive you should be shortlisting for a new system build this year?
Storage
The 256GB capacity class is the sweet spot for enthusiasts. This size maximizes the price, capacity and performance ratio. SanDisk has high hopes for Extreme II, but in order to sell these drives in big numbers, it has to do well here.
Storage
The SanDisk Extreme II 480GB SSD proved beyond a shadow of a doubt today that its an enthusiast class drive worthy of being included among the likes of OCZ’s Vector and Samsung’s 840 Pro.

Concluding our coverage of SanDisk Extreme II flagship SSD, we look at the largest capacity sized offered, 480GB.

Über SSDs mit einer Mischung aus MLC- und SLC-Speicherchips wurde bei Herstellern schon häufiger nachgedacht. In SanDisks Extreme II wurde das Prinzip realisiert – mit Erfolg?

The 3 drive SanDisk Extreme II array broke a lot of lab records today and clearly displayed that SanDisk has on their hands a top tier drive capable of jaw dropping performance.
