"Until recently, all SandForce-based solid state drive storage products came with a reserved NAND flash capacity referred to as 'Over Provisioning', used for low-level tasks by the SSD controller. Available now with the ADATA XPG SX900 series, a LSI-SandForce 2281-based solid state drive, capacity grows 7% larger thanks to new firmware that specifies binary capacity points while preserving performance. In this article, Benchmark Reviews tests the value-priced 256GB ADATA XPG SX900 SSD (model ASX900S3-256GM-C).
ADATA knows that SandForce-driven SSDs are a win-win combination of performance and speed. In this article, Based on the popular SandForce SF-2281 SATA 6Gb/s controller and fast IMFT-branded NAND flash components, ADATA claims the SX900 is capable of 550 MB/s read and 530 MB/s write speed with 4K random write speeds as high as 90,000 IOPS in real world testing. We test these claims, and compare performance to competing storage solid-state solutions in this review to find out which SSD is best.
The second-generation SF-2281 SSD processor maintains all of the original core technology SandForce originally introduced in the SF-1200 series, but now improves SSD performance with 20% faster IOPS and 40% faster sequential read/write throughput. They've enhanced BCH ECC capability, and the new processor now supports ATA-7 Security Erase. Finally, the new SF-2200 series implements cost-effective 20nm-class NAND flash from all leading flash vendors with Asynch/ONFi1/ONFi2/Toggle interfaces."
