Sandforce SF-2200 and SF-2100 Break New Performance Barriers
SandForce has taken a leading role in the field of SSD controllers and appears to extend it with the company’s new SF-2200 and SF-2100 processors. Out of these two the SF-2200 is particularly impressive, offering 500MB/s read AND write speeds over SATA 3, as well as 60,000 IOPS in 4K random reads.
These chips will appear in devices from several manufacturers; the confirmed ones so far are OCZ (Vertex 3), Corsair (Force GT), and Patriot (Wildfire). The bar for hardware-based encryption has also been raised with support for AES-256. Here are the key changes in the new product line:
- 6Gb/s SATA III (SF-2200 only)
- 500 MB/s Sequential Read and Write (SF-2200 only)
- 60K IOPS Random Read (4K transfers)
- 60K (burst)/20K (sustained) IOPS Random Write (4K transfers)
Security and Reliability:
- TCG OPAL with AES-256/128 and double encryption
- Support for 30nm & 20nm SLC, MLC NAND Flash
- Asynch/Toggle/ONFi2 interfaces
- Up to 166MTBinary user capacity points (RAISE off mode)
- Enhanced ECC with BCH and 55 bits/512 byte sector
This is the biggest news in client-side/consumer SSDs for quite some time and if no unforeseen issues arise we fully expect that drives with these controllers will top the sales charts for some time to come. The following are ATTO and PCMark Vantage benchmarks supplied to us by SandForce:
These numbers were achieved with Micron 25nm MLC NAND on an AMD motherboard with SATA 3.0 6GBps.
