The RamSan-70 boasts sustained read rates of 2.5GB/s and up to 1,200,000 IOPS - but you'll have to dig deep if you want one in your system.
For the storage fan with money to burn, Texas Memory Systems (TMS) has announced what it claims is the world's fastest PCI Express-connected flash-powered solid-state drive: the RamSan-70.
Using 685GB of single-level cell (SLC) NAND flash parts - of which 450GB is usable, with the rest given over to overprovisioning and RAID parity storage for reliability and performance purposes - alongside a hefty on-board PowerPC CPU, TMS claims that its RamSan-70 can hit 2,500MB/s sustained read with between 300K-1,200K read input/output operations per second (IOPS) and 220K-440K write IOPS, along with a write latency of 30 microseconds. This bandwidth is sustained through an 8x PCI Express 2.0 connection to the host.
TMS claims it's the fastest flash-based SSD around, and it's hard to argue: rival products like the OCZ RevoDrive 3 max out at around 1,000MB/s read and 130,000 write IOPS to the RamSan-70's 2,500MB/s and 440,000 write IOPS. With figures like that, the RamSan-70 is likely to prove popular with IO-heavy enterprise users with deep pockets - and doubly so with the inclusion of integrated RAID-5 support to maintain data integrity should a single chip fail, on-board ECC error-checking and the availability of an optional mezzanine card which doubles the usable capacity to 900GB/s.
Before you get excited, however, there's one key point in TMS's marketing: the RamSan-70 is a professional product for professional users. Its use of SLC NAND flash, rather than the cheaper multi-level cell (MLC), means stunning performance but at a serious cost. Although an official selling price isn't available, we're going to conservatively put this in the box marked 'after our numbers come up on the Lottery.'
