as its sustained transfer rate exceeds 70MB/second on the outer parts of the drive, compared with about 60MB/second for the 7200rpm Seagate Barracuda drives more commonly used in musicians' PCs. Moreover, its random access time is significantly better, which should help those among you who ...
As an illustration, the insulation class of a voltage transformer (VT) used on a 7200Y/12 470 V system should be a minimum of 15 kV, despite the VT having a main rating of 7200 V and being connected phase-to-ground. During a fault scenario, the voltage transformer (VT) may experience...
Now, it is worth remembering that these are NOT your common, everyday SATA hard drives and are designed to be rugged, high-performance disks (7200RPM, 512MB Cache, 10x 2.2TB platters, etc). In a RAID 0 and RAID 5 setup and in particular file size tests, full saturation of read ...
