I am the original owner of this high-speed drive, which is new in the factory sealed packaging. It was purchased as a backup unit, but my original drive continues to function reliably. This model includes a pre-installed heat sink. The 1TB SATA drive features a 10,000 RPM spin speed, a 64MB cache, and an MTBF of 1.4 million hours. It is engineered for photo and video editing applications and serves as an excellent secondary hard drive in a desktop system utilizing an SSD as the primary boot device.
