Review: Sandisk ExtremeAfter developing its own controllers, namely the G3s and G4s, over the last year Sandisk has been using the SandForce chips among others.
While the Sandisk Ultra uses a SandForce SF-1200 SATA 3G, the Sandisk Extreme uses the usual SandForce SF-2281 SATA 6G. The originality of this SSD comes in its 24nm Toggle flash made in partnership with Toshiba at its Flash Forward joint-venture.
The Sandisk Extreme is 9.5mm high. It's guaranteed for three years and comes in a box that only has a short manual inside it in addition to the SSD. The fact that there isn’t a 3.5" adaptor isn’t really a problem however, given that all modern casings support 2.5" SSDs natively.
The official specs only give figures for highly compressible data, with therefore very high sequential speeds (writes illusory). As we can see however, random reads get faster as we go up the range and the 480 GB version suffers in comparison to the 240 GB version when it comes to random writes.
Inside the Sandisk Extreme you’ll therefore find the SandForce SF-2281 and four 32 GB 24nm Sandisk Toggle flash chips, each with four 8 GB dies.
