NAND flash XMC card

  • 21-Dec-2010 08:40 EST

The XMC-552 from Curtiss-Wright Controls is a rugged XMC/PMC card that is visible to the system as two independent SATA drives and comes in 64, 128, or 256 GB configurations. The card speeds and simplifies the integration of large-capacity solid-state flash memory into deployed subsystems. Designed for use in demanding military environments, it provides data protection features including 128-bit AES data encryption using a programmable key, an instant purge function that enables the erasure of all memory within 4 s, and secure data erase. The sequential read performance of the flash memory is rated at 200 MB/s, which can be increased to 400 MB/s with RAID 0 software. The card supports ECC NAND flash correction, which can correct up to eight random single-bit errors per 512-byte sectors. It also supports a wear-leveling algorithm that spreads program/erase cycles evenly across the media to mitigate premature device failure due to frequent data overwrites.
