Six 2.5” High-Capacity Notebook Hard Drives

Advanced Format technology makes it possible to build 9.5 mm high 2.5” hard disks with 500 GB per platter. The result is a range of slim and speedy storage giants.

Benchmark Results: Streaming Reads/Writes

It seems obvious: performance-oriented hard drives with 7200 RPM spindles and correspondingly low access times should top the charts in Iometer’s streaming benchmark.

The reality is a little bit different, though. While Western Digital’s WD7500BPKT sits unchallenged at the top of the chart, the other 7200 RPM disk, Toshiba’s MK6461GSYN, and two 5400 RPM models (Samsung’s Spinpoint M8 HN-M500MBB and Western’s Digital Scorpio Blue WD10JPVT), are clustered together below. Samsung’s Spinpoint M8 HN-M101MBB and the slowest drive, Hitachi’s Travelstar 5K750 HTS547575A9E384, trail far behind.

    On the western digital hard disk page the Western Digital Scorpio Black WD7500BPKT is mentioned as 750 TB please correct it.

    Nice article as a whole

    Good to have all the latest data in one place. Wish Dell had put in the 750GB Scorpio Black instead of 750GB Momentus in my XPS15.

    One minor point: good to know that i7-920 is now part of Sandybridge. Can you check???

    Wonder how well these things survive the drop test. If they can survive a fall that a SSD can sustain then I'll be up for it. Other than that wish higher capacity SSDs become cheaper.

    Talk about a bad time for a hard drive comparison...

    GoFlex is a Seagate disk product line not Western Digital

    Western Digital hard drives sound good in theory for laptops, but they're not. I would never use one unless they fix a fatal flaw.

    What flaw? The fact that the hard drive automatically goes to sleep (parks its head) after eight seconds of inactivity, and since this is hardwired into the firmware it completely dismisses what you set in your Power Options in the Windows 7 Control Panel. Why is this bad? Because if the HDD is inactive for more than eight seconds it needs to unpark its head, and that creates a very noticeable lag when launching applications or working with files because the process takes a few seconds to complete, not to mention it puts more stress on the HDD mechanics.

    Unless it's simply for a storage drive where you don't care about performance I recommend you go with Seagate, Hitachi, or Samsung for laptop HDDs instead.

    Current prices are a bit higher than what is mentioned in the article, actually pretty scary:

    Hitachi 750GB $140-160
    Samsung 1TB $220
    WD 750GB $160
    WD 1TB $230
