Hitachi Releases World's Most Energy-Efficient HDD 118

Posted by ScuttleMonkey from the fewer-hamsters-required dept.
An anonymous reader writes "Today Hitachi released what they are calling the 'world's most energy efficient desktop hard drive' capable of reducing the active and idle power consumption by up to 40 percent over the previous generation." The drive will come in a range of flavors starting at 250GB and ranging to 500GB. Hitachi is promising these drives in high volume later this year.

      B) Latency. Nowhere did they mention the "wake-up" time from the Low RPM mode, but you can guarantee it's horrendous. "Average Latency" as the specs say, only tell you what happened during test conditions, conditions very unlikely to put it into Low RPM mode.

A decent sized(say, 300gb, because that's what's on newegg right now) 15k RPM SCSI drive from seagate will cost you $700. Why spend $1400 on 300gb of storage(you do need rendundancy if you need a 15k RPM drive), when you can spend the same money on a larger, faster array?

While everything has its place most midsized and larger shops are going to have a lot of $ wisely invested in 10&15k drives. We use SATA for DR, archival storage, and disk to disk to tape, and that's about it.

          --Yep. I don't burn anything at >24-32x (and shop AROUND for 32x-max cdrom drives/burners) because I had a LIBRARY CD *shatter* in my crappy 52x CDROM drive a few years ago. True story.

  • I think that while a power-cutting hard drive for desktops, workstations, and servers is a great idea, I think that would be much more critical for a laptop, since power is its biggest limiting factor (i.e. the obvious). Why don't companies focus on maximizing flash storage for higher performance in these settings? That way, servers can not only get completely awesome read speeds, but hopefully boosted write speeds at rates comparable to platter-based hard drives. Or, at least until that idea substantiates,

    Hitachi is promising these drives in high volume later this year.
    Damn, I was hoping that the drives would be quieter too.

      No, I am sure they can manage all three: high speed, high efficiency, high cost. No problem.
    • Exactly, I'm not impressed anymore when a company focuses on a single problem like efficiency and makes a whole series of products around it, ignoring other attributes. I'd be all for Hitachi if they took this capability/technology and just incorporated it into every drive they sold from here on out. That would be impressive and a significant step forward, rather than trying to exploit one specific group of people with a specialty product.

    But how does it compare against Western Digital's 1TB Green Power drive?
  • Can they use this to make an external USB drive that doesn't get hot enough to fry bacon, even when no data has been transferred to/from it for hours?

    Cause that drives me nuts.
