Developed by DNF, HSS combines standard disk drive technology with random access memory in an intelligent design that maximizes performance and energy efficiency. This hybrid technology fits into a standard 3.5 drive bay and uses a standard serial ATA interface, allowing existing systems to be retrofitted to support the new disk drives.
Traditional Solid State disk technologies are extremely expensive, at about $250 per GB, and are only available in 8, 16 and 32GB capacities, said Mo Tahmasebi, CEO of DNF. DNF address these shortcomings with Hyper Solid State disks that offer 15 times the storage capacity at a similar price.
With capacities of up to 200GB per disk, the new drives use 16 percent less power than 146GB, 15,000-RPM SAS disks, and 24 percent less than 15,000-RPM Fibre Channel disks. In addition, with power consumption of only 12.5W, they use less power than a standard 500GB 7200 RPM drive.
According to Tahmasebi, the HSS also compares favorably with Solid State disks. Performance is comparable to traditional Solid State disks, but HSS offers higher capacities than the readily available 8 and 16GB Solid State disks, he said. In addition, not only is HSS a better choice for storage systems in demanding, transaction-intensive applications, but it also reduces operational costs with lower power consumption.
