A Closer Look at Hitachi’s new 2.0TB 7200RPM DeskStar 7K2000 Serial ATA Hard Drive

Hitachi_2TB_HardDisk_Deskstar_7K2000As mentioned in my post from Friday, we received stock of Hitachi’s new 2.0TB 7200RPM DeskStar 7K2000 Serial ATA Hard Drive. By popular demand, we tested the three drives mentioned in that post internally in a Mac Pro to show just how much of a difference rotational speed can make when not limited to the ever-popular FW800 interface.

We benchmarked all three of these drives using the QuickBench TM 4.0 Extended Test. This test measures the drive’s ability to sustain large amounts of data (measuring between 20MB and 100MB) transferred to and from your computer.  But then measured speeds using two hi-definition tests AJA System Test and BlackMagic Disk Speed Test.

The Contenders:

2.0TB Hitachi 7K2000

7200RPM Rotational Speed

32MB Cache. (HIT0F10311)

2.0TB Seagate Barracuda LP

5900RPM Rotational Speed

32MB Cache (SEAST32000542AS)


2.0TB Western Digital RE4 Enterprise Class

IntelliPower Rotational Speed

64MB Cache(WDGWD2002FYPS)

  • Just goes to show that like the old speed shop sign:
    “There’s no replacement for displacement.”

    one can make a similar statement for pure 7200RPM 2TB drives:
    “Exact rotation eliminates any speculation.”
