Seagate Announces First 1.5TB Desktop Hard Drive

Posted by timothy on from the they-had-to-count-them-all- dept.

MojoKid writes "Seagate announced three new consumer-level hard drives today, which it claims are the 'industry's first 1.5-terabyte desktop and half-terabyte notebook hard drives.' The company claims that it is able to greatly increase the areal density of its drive substrates by utilizing perpendicular magnetic recording (PMR) technology that is capable of delivering more than triple the storage density of traditional longitudinal recording. Seagate's latest desktop-class hard drive, the Barracuda 7200.11, will be available in a 1.5TB capacity starting in August. The 3.5-inch drive is made up of four 375GB platters and has a 7,200-rpm rotational speed."

    Copy the following into your URL bar and press Enter. The code will allow you to compute the real amount.

    javascript:var capacity=window.prompt("Enter the capacity in TB.");capacity=capacity*0.9094947;alert("Real capacity is "+capacity+"TB");

    Good Source is Storage Review

    The top 34 drives all do at least 54mb/sec MINIMUM and at least ~80MB/sec maximum. The top 15kRPM cheetah doing 82.7-135MB/sec.

    If i were to pull a number out of my ass I would say 78-135MB/sec (min/max) on the new 1.5TB drives.

    I would say if you have 750gig seagates and you are only getting 25MB/sec you have a bottleneck. Those drives should do a MINIMUM of at least 40MB/sec...
