AData’s S511 series of SSDs is built with 16 modules of Intel 25nm synchronous NAND flash memory. The asynchronous version of this drive is Adata S511 SSDthe S510 series. This drive is available at capacities of 60 GB, 120 GB, 240 GB and 480 GB. Equal read and write speeds of 500 MB/s can be reached by the S511 series of SSDs. The drive IOPS is 60,000 at 4K random write aligned and a maximum of 85,000.

The drive comes with a three year warranty with a Mean Time Between Failure (MTBF) of 1,000,000 hours. Windows TRIM command is supported by this drive which aims to extend its life. Similar to other SandForce driven SSDs like Patriot’s Wildfire, the S511 series can withstand a force of 1500 G. The drive must be operated within temperature constraints of zero to 70 degrees. The solid state drive is packaged with a 3.5 inch adapter.

With so many SSD makers opting for the SandForce 2281 controller, manufacturers will inevitably struggle to differentiate their products from others. The ADATA S511 240GB’s approach seems to be the most sensible: it matches the SandForce 2281 drive controller with affordable yet fast synchronous 25nm NAND, and drives down the price without compromising on performance.

So there you have it, if you are seeking l33t performance in the storage segment then the S511  series offers just that, really good performance. Hopefully you can find it for a price that is acceptable for you. The product is fairly similar to OCZ, Patriot and Corsair’s latest SSDs with that SandForce 2281 Controller based products so ultimately I’d go for the best price versus warranty if I where you, ADATA offers three years of it.

At the end of the day, we now add yet another ‘SandForce Driven’  SSD to the mix giving the consumer just a bit more to think about.  Things that we would definitely consider are the fact that AData will have kits designed for migration to the notebook or desktop where one will find either an external drive adapter for notebook migration or a 2.5″ to 3.5″ desktop adapter, as shown here, for desktop installation. Add to that the fact that AData partnered with Acronis for hard drive to SSD migration and you just can’t ask for more!
