Aren ATA-based Arrays slow?
A. While most competitors provide simple connectivity to the slower ATA drives using an underpowered RAID controller, the Diamond RAID Array takes a different approach. The Diamond RAID Array utilizes a high-performance, sophisticated RAID controller technology to aggregate the performance of all 24 drives in the array to sustain benchmark performance data-transfer rates of over 240 MB/sec. The Diamond Array’s internal RAID architecture uses the latest advances in ATA drive technology, including Command Overlap, Command Queuing and Double Clocking of Data Transfers to provide performance equal to or better than most native Fibre Channel or SCSI arrays. Using ATTO’s proprietary patent-pending hardware-assisted ATA Interface Engine (AIE), the Diamond Array performs very fast data transfers from drive to controller via Ultra DMA protocol that operate at 100 MB/sec. Because this is a hardware solution, rather than the traditional software polling method of the ATA interface, the Diamond Ar
