That is a pretty steep price considering we managed to find the 7,200 RPM model, 7K4000 for just $326, both prices via Google Shopping.Īccess times for strictly long-term storage devices are not as important as they are for boot disks. It's since tipped up online for $399 in the US. When we started writing this article the Hitachi GST 5K4000 was not available. HGST claims the new 5K4000 uses 24% less power per gigabyte than the previous generation 3TB HDD. The performance, especially the random access performance is lower than the 7,200 RPM models like the 7K4000, but the user gets a product that is quieter, cooler and uses less power. This allows the drive to remain silent and cool while in use. The drive uses a 32MB data buffer, half the size of the new Western Digital Red Series that we recently reviewed.Īs we mentioned in the introduction, the 5K4000 uses four 5,900 RPM platters. Hitachi GST doesn't list any performance data, but that's what we're here to determine anyhow. The drive also uses Advanced Format, a standard were seeing quite often these days with mechanical disk drives. The new Hitachi GST 5K4000 uses a SATA 6Gbps interface that increases the burst speed above the limits of SATA 3Gbps.
