Hitachi Deskstar 7K1000.B

Acoustically Manage Your Hard Drive
By

Most readers should be familiar with the Hitachi Deskstar 7K1000.B, which has been Hitachi’s top model for a few months. Compared to its predecessor, the 7K1000 (without the B) , it delivers considerably better throughput of up to 111 MB/s and much better application performance. It is now based on only three storage platters rather than on the five-platter design leveraged by the original 7K1000. Hitachi upgraded its warranty for retail products, resulting in a five-year factory warranty, which is also the case for Seagate and WD upper mainstream drives. You can check the warranty status of your Hitachi drive on the Hitachi website.

Although we used a 1 TB Deskstar 7K1000.B, you can choose among several different capacity points and get the same excellent feature set, starting at 160 GB. Most of the drives come with 16 MB cache memory, and all utilize a SATA/300 interface with Native Command Queuing. Hitachi also has models that come with built-in, real time data encryption, called Bulk Data Encryption (BDE) .

All statements we make about acoustic management are also valid for the other models, but the exact results may not necessarily apply, since lower capacity drives come with one or two storage platters instead of three. This has an influence on idle noise as well as on access noise, as there are fewer heads to be relocated.

We found that the latest Deskstar 7K1000.B is a very balanced drive and hence is suitable as a system drive. It delivers nice application performance, throughput that is above the average, and reasonable power consumption. As a result, the drive provides nice performance per watt results. Other terabyte drives, such as the Samsung Spinpoint F, provide higher throughput, and a WD Caviar Black is the faster application drive. But no hard drive is perfect, and the differences are in fact small.

Let’s look at the results with AAM set to either “fast” or “quiet. ”

    Unless you work in a studio, the sound from a HDD is so incredibly little I doubt most people even notice it.

    Even on a near fanless system, with only a psu fan, that single fan would make more noise.. This all seems a little silly imo.

    The sound from the hdd is by far the loudest part of my system.

    Quick question - was AHCI / Native Command Queueing enabled on the drive?

    err, my 250gb SATA seagate was by far the loudest thing in my system. could hear it clearly scratching in games >< love my new WD 250gig tho - absolutely silent even with the side of the case off :)

    To asdasd123123:
    I agree with you, and also this Hitachi feature is very old one, I recall I was playing with it on my old 80 GB SATA2 HDD. It does make a difference till I bought Antec 180 :p 

    To daskrabbe:
    If u can hear your HDD screaming then you should change it!
    Pay some respect to it because it kept your data safe for lots of years!

    Also if it's new, change your cheap case, because it makes every other part of hardware vibrate!

    Invest in an SLC SSD. Noise problem solved.

    Interesting article. I've been fiddling with computers for the last 12 years and I've never heard of AAM before! It seems like a viable option to reduce noise in a system. However, in my case, my GTX260 is the loudest part I have, even outside games. I'm not sure I would notice an impact at all. Maybe I should do some testing before judging though.

    I have always disabled AAM on all my drives that I possibly could, Performance > Noise ;)

    Noise? ok, How about the CD/DVD drive! The changes in loudness and pitch are constantly averting my attention.

    Yeah but who uses an optical drive these days? And when you do use it, do you use it constantly for hours? I use my drive to rip music, movies and games and that's pretty much it. Daemon tools takes care of the rest when I need a CD to play a game.

    the loudest in my system is a high frequency noise when the system is idle. i suspect its my cheap asus am2 motherboard.

    Apparently you've never owned an original WD Raptor drive. I have two paired in a micro atx case sitting on my office table and I can attest that they are quite noticeable, although they are tolerable.

    Me too! Performance = time. My time is more valuable than some old hard drives longevity and my appreciation of silence. AAM makes barely any difference in noise anyway.

    To Zak who posted before you: If you've built PCs for 12 years and never heard of it, then I would have to ask what you've been doing for 12 years... I discovered it before I'd ever even built my own PC.

    Could you enable this in the bios, or is that a different feature?

    GREAT article! Silence is a must for me, especially as one of my machines is located in the living room and is almost always on! TY

    thank you so much for this! I was unaware of such an option, and my hard drive drives me nuts if it gets going while I'm asleep (it will actually wake me up). Now I can barely hear it.

    You wouldn't be putting a raptor in a silent computer in the first place, that argument doesn't make any sense.

    I can admit I haven't owned either Hitachi or Seagate drivers for years, and WD drives has only made noise after a few years.
    A little too many Seagates have broken around me to ever buy one again..

    My three Samsung F1 1tb drives atm, are dead silent. I only hear them when the spin up, but when they hit their target RPM it just goes silent again.
    My case is nothing special, although it is a very thick-sheet iron case.

    Gratz?

    For my part, I guess I was just doing "normal" stuff. Building, configuring, tweaking, fixing errors, removing viruses and spywares, making backups, etc. It didn't occur to me that I could "downgrade" my hard drive in order to save a couple dB. Like I didn't think that downclocking a CPU could be very useful. It's just me I guess.
