Savvio is the first 2.5-inch enterprise disc drive, making possible a new class of high I/O, high-density storage solutions. Savvio enables space-constrained data centers to achieve higher IOPs (input/output per second) performance in small form factor system configurations while maintaining the highest levels of reliability.

Savvio drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo TECHNOLOGY, and a Serial Attached SCSI (SAS) interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density storage requirements.

Savvio drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface characteristics of this drive. Savvio drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either SAS or SATA hard disc drives. This allows you to continue to LEVERAGE your existing investment in SCSI while gaining a 3Gb/s serial data transfer rate.
