HGST Enterprise Ultrastar 7K4000
3.5 Merevlemezek

Massive space Up to 4TB for capacity-optimized enterprise applications
Enterprise-class reliability Field-proven second-generation design specified at 2M hours MTBF

HGST Ultrastar 7K4000 is the worlds first 4TB 7200 RPM hard drive with a 2.0 million hours MTBF specification and backed by a full 5-year warranty, originally offered with SATA 6Gb/s and now also available with a SAS interface. Ultrastar 7K4000 represents the sixth-generation HGST 5-platter design, which has been field proven by top server and storage OEMs and Internet giants. Engineered for the highest quality, the Ultrastar 7K4000 is put through grueling design tests during development and must pass stringent ongoing reliability testing during manufacturing. Ultrastar 7K4000 delivers by reducing downtime, eliminating service calls and minimizing TCO.
