3 TB: Hitachi Deskstar 7K3000 (HDS723030ALA640)

Hitachi's 4 TB Hard Drives Take On The 3 TB Competition
By , Achim Roos

Hitachi’s second 3 TB drive spins at 7200 RPM and has 64 MB of cache memory. As a result, its specified throughput is much higher: 1656 Mb/s instead of 1366 Mb/s (that's 207 versus 170 MB/s). Real-world throughput reaches up to 152 MB/s according to h2benchw and 148 MB/s in our Iometer streaming reads test. These are commendable results that are only beaten by the new Deskstar 7K4000 and Seagate’s Barracuda 3 TB, which actually gets close to 200 MB/s.

The 7K3000 family is also available in 2 TB and 1.5 TB flavors, and they’re all specified for 24/7 operation. Power consumption is higher on this 7200 RPM drive than on Hitachi's 5K3000. That's simply the price you have to pay for higher throughput. We measure 4.9 W at idle for the 5400 RPM 3 TB drive and 7.1 W at idle on this 7200 RPM model. The 4 TB versions have very similar power requirements.

Since the performance difference between the 3 and 4 TB drives isn't too significant, we again have to recommend that anyone shopping for a high-capacity disk consider living with the 3 TB model if the last gigabyte isn't absolutely imperative. You simply spend a lot less money per gigabyte when you compromise down to the smaller drive.

You can find comprehensive hard drive performance comparison in our 2012 Desktop HDD Charts.

    Intervals between new capacities keep getting longer and the % increase in the new capacities keeps getting smaller.

    Three terabyte hard drives continue to offer the best cost per gigabyte of storage space. Two terabyte drives offer even better value at similar performance levels.


    Is it just me, or do those two sentences contradict one another?
