The PBOD is a solid state hard drive implemented as a PMC card with just a Bunch Of USB flash Drives. The PBOD supports industry standard ECC NAND Flash correction as well as wear leveling on card. No additional external software drivers are needed. Wear leveling is extremely important in solid state drives as it increases the life time of the NAND devices. NAND Flash devices are limited in the number of program/erase cycles that it can endure, typically, 100,000 cycles. The wear leveling algorithm spreads program/erase cycles evenly across the media. This avoids premature device failure due to frequent erase cycles on the same block of Flash memory.
The PBOD is supported natively by operating systems that support USB Flash drives. This includes VxWorks® and Windows™.
The PBOD supports transfer rates of 10 Mbytes/sec from each drive. With RAID software performance of over 40 MByte/sec has been sustained.
The PBOD supports up to 64 GBytes of disk space with current NAND Flash technology (16 Gbit devices). Standard PBOD storage densities are 16, 32, and 64 GBytes.
The PBOD also supports hardware write protect. The user can set the state of write protect either via jumpers on the card or via backplane pins. A Self Destruct feature is provided for secure data environments.
