Disk Array Expands to 80 TB with 1 TB SATA Disks
Features RAID 6 Dual Parity for Large Arrays

Burlington, MA. September 12, 2007. Winchester Systems Inc., a leading data storage solutions company, today announced a new SATA disk array that expands to 80 TB with 1 TB disk drives. As disk arrays increase in size, so do the chances of a rebuild failure. The company features RAID 6 dual parity to protect data during rebuilds.

The company's FlashDisk SX-3498S disk array provides up to 80 TB of storage using a base unit that includes a single RAID controller and 16 high capacity disks. The base unit supports up to four expansion shelves, each with 16 drives, for a total of 80 high capacity SATA disk drives and provides outstanding reliability and performance with very low cost per terabyte. The SX-3498S also provides four 4 Gb Fibre Channel host ports to provide "SAN-In-A-Box" connectivity to as many as four servers without the need for a Fibre Channel switch. A dual redundant controller version, FlashDisk SX-3494R, offers up to three expansion shelves with a total of 64 high capacity SATA disk drives for up to 64 TB of total capacity and eight 4 Gb Fibre Channel host ports.

The FlashDisk SX-3400 Series of products is perfect for the highest capacity applications including deep archives, security video, medical imaging, backup, snapshot, disaster recovery, virtual tape library, data acquisition, digital imaging and audio. The unit delivers impressive performance for SATA secondary storage device delivering 1,052 MB per second sustained throughput and over 117,000 disk IO operations per second.

"The introduction of the 1 TB disk drive is a watershed event in the industry," according to Mr. Joel Leider, the company's chief executive officer. "The 1 TB disk drive means that 224 TB of FlashDisk storage fits safely and reliably into a 42U high cabinet and that five cabinets will provide well over one petabyte of storage in just 30 square feet of floor space."

The company's chief technology officer, Mr. Jerry Namery explained, "Winchester Systems proudly features a unique high speed RAID 6, powered by a dedicated hardware ASIC, to provide high-performance dual parity to protect against two drive failures and to help ensure that critical disk rebuilds, after a disk drive failure, are successful - especially important with today's large arrays." He added, "The hardware ASIC is key to creating a RAID 6 array that has sufficient power to provide high performance."

According to the company's white paper, "Enterprise RAID 6" (www.winsys.com), RAID 6 dual parity offers 500 to 30,000 times longer MTDL (Mean Time To Data Loss) than RAID 5.

The FlashDisk SX-3498R models using 1 TB disks are available now and start at under $20,000. Delivery is 2-3 weeks ARO.
