Fusion-io brings RAID to solid-state storage
Fusion-io has implemented full-chip redundancy on its ioDrive, bringing RAID-class redundancy using "flashback" protection down to the card level. The company integrated a dedicated NAND flash chip on its PCIe card, which serves as a XOR parity chip, eliminating data loss due to chip failures and extending the card' lifetime. The NAND Flash chips on the ioDrive PCIe card contain a storage architecture that resembles a SAN at a fraction of the power, size and cost of traditional disk arrays. Other features include a RAID 5-like spare parity chip, and improved read/write performance peaking at 800 MB/sec.

WD hard drives are cooler than their predecessors
WD is shipping a backplane-compatible version of its VelociRaptor 10,000 rpm SATA hard drive. The backplane version is designed for 3.5-inch drive-based servers and workstations that require a backplane structure. The drive features twice the capacity, a 35% performance increase and runs 35% cooler over the previous generation of Raptor drives. Moreover, the 2.5-inch drive is enclosed in an IcePack, a 3.5-inch mounting frame with a built-in heat sink -- a customization that fits the drive into a standard 3.5-inch system bay and keeps it cool even when installed in a high-performance desktop chassis.

Intel shrinks PATA solid state drive
Intel now offers a smaller version of its Z-P230 PATA solid-state drive (SSD). The original 40-pin ZIF version is four times smaller than a 1.8-inch hard disk drive. The upgrade, a low-power, flash-based SSD, is currently available in a PCIe mini-card module, and comes in 4 GB and 8 GB models; a 16 GB version is due in September.

Fantom GreenDrives cut power consumption
Fantom Drives has made available the G-Force GreenDrive line of external USB and eSATA disk drives, which are designed to use up to 40% less power without sacrificing performance. The drives are available in 500 GB and 1 TB models.
