M224 Mass Storage PMC/XMC

The Aitech M224 is a complete SATA mass storage PMC/XMC solution suitable for harsh environments. The board incorporates no moving parts, providing higher reliability and consuming significantly lower power than rotating media hard drive storage solutions. M224 memory comprises two banks of NAND Flash devices providing a maximum total capacity of 512GB. Each Flash bank is managed by its own SSD controller, enabling operation as an independent SATA II Flash disk. The SSD controllers' built-in bad block management, wear leveling, and error correction ensure reliable high speed operation and minimize the burden on the host processor. An on-board RAID processor provides standard RAID functionality so that the two Flash disks can be configured for maximum performance (RAID 0 – striping), maximum data integrity (RAID 1 – mirroring), or maximum capacity (JBOD – concatenation). Performance of the M224 is exceptional, with sustained sequential read and write data rates of up to 210MB/s and 140MB/s respectively, when configured with SLC Flash memory and when operating in RAID 0 mode. PCIe and PCI-X controllers, together with standard PMC/XMC connectors, enable the M224 to be used with a vast number of host boards, for convenient incorporation in nearly any rugged system. The M224 has no socketed components. All components are soldered on the board, making the M224 suitable for use in high vibration and shock environments over the full military temperature range.
