HD Tune 2.53



Our first screenshot is the Hitachi drive with Automatic Acoustic Management turned off, NCQ turned on, and Volume Write-Back cache enabled in RAID 0 operation with the second screenshot showing the same configuration with a single drive. The RAID 0 setup shows a 93% increase in the minimum transfer rate and a 91% increase in the average sustained transfer rate. The maximum transfer rate also increases 95% with the burst rates increasing significantly although in actual operation this number is not completely valid. Turning off the write-back cache setting lowers the burst rate to 144.8 MB/sec. The RAID 0 setup is also reporting improved access times which once again reads 14.4ms with the write-back cache setting turned off.

Hard Disk Performance: HD Tach 3.0



We are also including HD Tach results for review. Once again the order of the screen shots is the same as in our HD Tune results and are based on the same settings. In this benchmark we see a 97% increase in the average read rates and a significant increase in burst speeds over the single drive configuration. These scores basically mirror the HD Tune results with the burst speed dropping to 204 MB/sec with volume write-back cache disabled. While these numbers are impressive, we will have to see if they translate directly to application scores.

    RAID 0 only give faster transafer rate of data from/to disk.
    It dosent give anything else faster even if you want it. If time for get or put data to disk dosent matter you have to buy a cheaper disk instead. Why weaste money on raptor or Deskstar.

    About raid 1, it isnt so good and safe. Accidents has happen with 2 disk system, 1 get failure and raid system transfer same fault to the other disk. In the end its no data on any disk that is usuable. The only tru safe is to have a backup of all data. Sould be taken at least every day. That is what the second disc should be used for and not RAD 1.

    I do believe that the main cost of stripping is the risk of failure. For everything though, you get what you pay for: the second drive, and the space associated with having a second drive. It is no harder to backup 2TB in RAID-0 than 2TB of individual drives, if you are going to have that much data, then it is an issue you are going to face anyway. So to me, it comes down to trading off risk of failure, and selected performance gains. I happen to think it is not worth it but I do think it is a matter of opinion (more of a 'to each their own' type of thing). Reply

    any one? I know its an extra drive. but you get some data protection, and some performance benefit, and you do not loss 50% of the drive space.

    but I heard bad things about on-board raid 5.

    I don't believe you lose any drive space in RAID 0, as there is no data redundancy. Reply

    The bad things you've heard concerning onboard RAID5 was probably performance related, which would most likely be true, since most onboard RAID would not have a good XOR 'engine', unless perhaps some of the server classed boards have them.

    As for Matrix RAID, I personally am a bit sceptical, from my limited understanding of it, it basically gives you the ability to do a RAID 0+1 array on two drives. Someone correct me if I am wrong.

    I thought last time I already criticized that reviewing the 1TB drive with RAID 0 performance is missing the point, yet you come up with a redux part on the same drive. First of all, I don't care how much Hitachi is paying YOU or AT to pimp this drive(obviously they paid the wrong guy). If you don't understand that comparing a 1TB drive against the raptors are STUPID, you should get your head checked. One is targetted at the MASS STORAGE people(you know, I should spell it out for you, the guys who want 4TB +) and the raptor is targetted at the people as a PERFORMANCE OS boot drive. COMPARING THOSE TWO DRIVES ARE STUPID!

    now, if you really need a triple redux on this stupid drive, you should cover power usage, noise, heat, and basically constantly read/write to the 1TB drive to see how long the deathstar will last.

    I will be honest:

    you are right about those: Personal Attach: Check and Use of ALL CAPS: Check

    you are wrong about the following:

    totally unsupported claim of bias? about what? about Hitachi drives being deathstars? Did you read that Hitachi bought the IBM deathstar hard drive business?

    Improper understanding of "are/is"...ok...typo..so what? Try typing the whole message in 20 seconds.....you is stupid :)

    comment that makes me look like an ass? So do you consider all criticisms make people look like ass?

    Misunderstanding of Market Segment: Really? Is it me who misunderstood? The whole point I made is that Anandtech shouldn't review the 1TB drive against the raptors because the difference in market segment. 1TB isn't about performance. It's about mass storage. Mass storage drives needs different measurements: reliability(MTBF), RAID 1/5/6 performance, heat, noise, power consumption. OS performance drives(raptors) need those benchmarks: IO, Seek, Sustained write/read, etc. you get the point. Firmwares are tweaked differently for those two opposing sides.

    I agree with the poster below you, Don't read the review: Check! To be honest, Anandtech hasn't come out with anything good for a while.(except that AppleTV review)
