Ultra High-Performance PCI-E Solid State Drives Reproduce New Forces

Consumer-grade SSDs generally use SATA interfaces, while PCI-E interfaces dominate the high-performance storage market. From Texas Memory Systems, Inc., Texas, USA. (TMS) today introduced the new seventh-generation product "RamSan-70" (Gorilla development code), using a half-height, half-length form of the PCI-E expansion card, a single card is equivalent to a complete set of storage systems.

The RamSan-70 uses the PCI-E 2.0 x8 system bus interface for the first time using the new Series-7 Flash Controller. Based on a high-performance Xilinx FPGA chip and PowerPC processor, it handles all flash management functions without the intervention of a CPU processor. It also integrates TMS's patented reliability technology with enterprise-class reliability such as chip-level RAID and advanced ECC algorithms. Sexual function, making the product life up to 6-10 years.

SLC NAND flash memory chips from Toshiba, 32nm process manufacturing, total capacity 640GB or 1280GB, of which 640GB from the main card, 640GB from the expansion daughter card, but the actual usable capacity is 450GB or 900GB, another 17% of the capacity is used as write acceleration and ECC, RAID two levels of data protection.

In terms of performance, the maximum bandwidth is 2GB/s, the read performance is 330,000 IOPS, the delay is 70 milliseconds, the write performance is 160000 IOPS, and the delay is 45 milliseconds.

RamSan-70 will be available in 4-8 weeks, mainly for OEM storage vendors, the specific price has not been announced.
