Solid State disks are becomming cheaper and more functional than ever before. The SSD has a faster access time and read time than a regular hard disk. The SSD are inferior to hard disks in the speed of writing data to them, but this can be overcome by rewritting the low level routins to take advantage of the SSD write characteristics to improve the data write performance of the SSD to that of the hard disk dirve.

SSD disk drives are more reliable, have wider operational temperature ranges and can sustain higher operation shock that a regular hard disk drive. By placing the SSD disks in a RAID 6 configuration two of the 5 SSD disks can fail without losing any operational integrity. This would allow a failed disk to be returned to Sumo Computer for replacement without completely compromising the disk array integrity.

Within the next 18 months new FLASH memory technologies will provide SSD disk drives with greater capacity and higher speeds than today.
