EG0300FCSPH is the OEM model number supplied in HPE option kit 507127-B21 for 300GB 2.5" SFF 6G Dual Port SAS 10K RPM Hot Plug Hard Drive. If you have read EG0300FCSPH off a drive label or a controller inventory report, this is the HPE part it maps to: a 300GB 10,000 rpm SAS hard drive with a 6 Gb/s dual port interface in a 2.5-inch low profile form factor, measuring 0.591" high and 2.75" wide. It ships hot-plug with the tray attached.
