If a fast and affordable SSD is what you’re looking for, the SanDisk Extreme 240GB is perfectly made for you. SanDisk has a big comeback after the success of his predecessor in the form of Ultra SSD manage to aim those mainstream users but, this time giving you a much better technology for enthusiast grade level of performance.

SanDisk no needs for further introduction, consumers are being aware of the name when it comes to USB Flash drive, the performance and reliability it brings are unquestionable. Now giving you the fastest SSD that is available at a very affordable price.

The SanDisk Ultra is using the older SandForce SF-1200 series controller that drives the slower SATA 3GB/s interface while the all new Extreme SSD uses the fastest controller up to date, no other than the famous SF-2281 and makes it possible with SATA 6GB/s interface.

Made by their own finest 24nm MLC Toggle NAND chips, as a result SanDisk have listed a blistering speed of 550MB/s for reads and 520MB/s in write. With this kind of potential, this is probably the fastest SSD you can buy on the market today.

Better Performance

Performance is not all about speed, if you’re constantly seeing a BSOD error on screen the SSD you’re using is more likely become useless. If we take into considerations an enthusiast level of performance we came up into different aspect such as reliability, compatibility and durability. Some SSD’s are made from various component, these companies are picking up others chips and put into one assembly.

Problems most often arise with this kind of setup with issues such as compatibility and eventually loss of reliability. SanDisk have developed their own chips as they are pioneer in flash memory making and this is what they took most of the advantage as the drive lean towards the best performance you can have. To give you a total peace of mind, SanDisk generously giving a 3-year warranty.

The Looks

The SanDisk Extreme 240GB looks good in red and white letterings in a black background colour; as you can see, it follows the same colour scheme as the previous Ultra SSD version. The drive seems to be tough in all metal casing unlike its competitors that is made of plastic. It comes in a standard 2.5 inch form factor with z-height of 9.5mm that perfectly fit in any laptops and netbooks.

Inside of it is the SF-2281 controller coupled with SanDisk owned high grade 24nm MLC Toggle NAND. It uses a total of eight NAND chips with four on both sides, each carries a 32GB in size to arrive at 256GB (32GB x 8 = 256GB) but only 240GB of these are usable.

SanDisk Extreme 240GB In Action

To see how good the SanDisk Extreme 240GB perform it was tested against the famous Intel 520 Series 240GB and OCZ Vertex 3 Max IOPS 240GB. To get things more interesting, these two are both using the same SandForce SF-2281 controller and consider as the fastest SSD on the market today.

The SanDisk Extreme 240GB gives a stunning result in 2MB Sequential Read/write Transfer speed with 499.58MB/s in read tied up with the Vertex 3 and topping the charts at 472.11MB/s in write. On the 2MB Random Read/Write transfer speed it continuously giving an excellent numbers with 498.54MB/s read and 471.92MB/s in write that completely dominates both the Vertex 3 and Intel 520 Series.

Moving on the smaller transfer size with 4K Random Read/Write speed, surprisingly it consistently leading the read chart with a solid 8,144 IOPS leaving the two behind with 7% faster than Intel 520 series and 22% compare to Vertex 3.


The SanDisk Extreme 240GB surprisingly made a big comeback with vengeance proving it to be a worthy enthusiast level of SSD. The written specs are close to its real world performance giving us a very strong result by beating the toughest competitor out there. On the aesthetic part of it, the drive is built with highly durable metal cases that looks and feel robust.

This wonderful SSD earns a perfect 5 star rating with 18 customers in a small period of time since its introduction to the market; this proves how decent the drive is. SanDisk did the right move for waiting the perfect time to fully mature the SandForce SF-2281 controller before they finally jump in. By using their home based made MLC Toggle NAND chips gives you the fullest advantage.

Having that said, it doesn’t suffer from any compatibility issues thus, delivering a highly reliable SSD on your laptop and desktop. Another excellent advantage of this that everybody will surely love is the price; it’s insanely low, nothing comes close to it and a 3-year warranty is an additional bonus. The reason behind this is that, they don’t need to buy from other chip vendor, by owning it they can offer the best price you can have. Speed, reliability, compatibility, durability and price what else can we ask for the best SSD?
