HGST CinemaStar 7K1000 750GB SATA 3.0 Gb/s 0A35273 プリント

ment to precisely maintain a constant fly-height 
through-out read and write operations. This 
reduces the raw soft error rate and, in turn, im-
proves overall data integrity, drive performance 
and reliability. 

CinemaStar 7K1000’s iridium-manganese- 
chromium (IrMnCr) read head sensor technology 
offers better performance and reliability in 
harsh conditions. 

Drive security

Drive security is provided through host-drive 
authentication (secure key exchange) during 
installation. Host-drive pairing ensures drives 
will only work with authorized hosts in the event 
of theft.
