Seagate Technology ST34520LC hard drive specifications

Seagate Medalist Pro 4520 - hard drive - 4.5 GB - Ultra2 Wide SCSI

Seagate's Medalist Pro SCSI provides an affordable SCSI storage option for desktop PCs, personal workstations and entry level servers. The drive spins at a fast 7200 RPM and features internal transfer rates from 108 to 192 Mbits/second. The Medalist Pro uses EPRML recording method. The Enhanced Partial Response Maximum Likelihood (PRML) technology keeps data clear from background interference and allows Seagate disk drives to increase areal density (disk capacity), boost transfer speed, improve yield through the drive's ability to self-calibrate and lower disk noise. It also uses Advanced SCSI Architecture II (ASA II) to increase drive performance and provide easy cross-platform migration. The 3.5 inch, low profile Medalist Pro hard drive supports Self-Monitoring, Analysis and Reporting technology (SMART) to help prevent data loss and provide advance warning of drive failures. It is compatible with popular operating systems such as Windows and NetWare.
