The Barracuda 36ES2
is an ideal solution for entry-level workstations and entry-level
servers that blends Seagate's best drive technology from its
IDE/ATA products and high-end SCSI drives providing an unbeatable
combination of price/performance value. The Barracuda 36ES2
benefits from significant performance enhancements with Seagate's
Advanced Multidrive System (SAMS) that optimizes performance
in server and RAID applications, and a Non-operating Shock of
350Gs to help assure data integrity during shipment and movement
around the office.
The Barracuda 36ES2 features a 7200rpm spindle speed, 7ms access
time, 2MB cache buffer, and a three year manufacturer's warranty.
The Barracuda 36ES2 utilizes the 68-pin Ultra 160 SCSI interface
which is capable of data transfer rates up to 160MB/second,
and is backward compatible with Wide, Ultra Wide, and Ultra2
controllers (will only support the controllers maximum transfer
rate).
