HD Tune / HD Tach


Click to enlarge

In previous HD Tune 2.53 testing the Hitachi T7K500 came in at 65.3 MB/s, Seagate's 7200.10 500GB drive at 63.1 MB/s, Western Digital's YS 500GB at 62.4 MB/s, and falling way behind at 51.5 MB/s was the Seagate 7200.9 500GB drive. The Samsung's 64.9 MB/s puts it near the Hitachi's class leading performance and slightly ahead of the Seagate drive.

With a reported read access time of 14.0ms, the Samsung drive finishes at the bottom of the pack of our 500GB drives with the Hitachi T7K500 having a 13.0ms score and the Seagate 7200.10 finishing at 13.2ms. Considering the rotational latency of a 7200 RPM spindle is generally 4.2ms, this leaves the SpinPoint T166 with a measured seek time of 9.8ms which is higher than Samsung's reported 8.9ms results.

In the HD Tach tests the sequential read speed at the 250GB level for the 500GB 7200.10, Hitachi 500GB, and WD 500GB averaged around 70 MB/s while the 7200.9 500GB was near 53 MB/s. The Samsung drive is once again very competitive with a reading right over 72 MB/s at the 250GB mark while finishing around the 40 MB/s mark at the end of the drive. As in the HD Tune tests, we a slight dip at the 25GB mark before the drive recovers back to the 80 MB/s range in the sequential read speed test.

It is important to note that access times, average read rates, and burst rate measurements are basically synthetic measurements, and while important these are not "true" application measurements. There is a great deal of potential bottlenecks elsewhere in the system that can and will affect the true performance of a drive. Although these "benchmarks" are a good indicator of a drive's performance, it is the total make-up of components in the PC that will determine the drive's actual performance.

    ive had 2 of these drives for 8 months now,, so the review seems late.


    obviously the new samsung 1TB 3platter drives are immensly interesting.

    the specs and samsungs history in this market makes it seem to be the drive to have in the next 12 months.

    I've purchased 3 of these drives, and 2 have failed in about 4 months time. One was in my pc, the other was in an external enclosure. (The one still working is in my HTPC).
    2 out of 3 failures in such a short time is pretty bad.

    However... the reason I won't be buying any more Samsung drives is not because they failed, but because they don't have an advance replacement program. That was fairly shocking to me! I took it for granted after sending it failed drives to Maxtor and WD (both of whom have outstanding service when it comes to that, BTW).

    Hard drive failures are a given, and I can't deal with that. A drive failure is too critical a problem to wait for a replacement more than a couple days. In my opinion anyway...

    Backup + cooling = No need to worry.

    I remember having a 20gb Western Digital Caviar, which did me the favour of giving me a special sign that it had come near the end of it's life, so I could replace it in time. If only all HDs could issue that kind of warning...

    Oh boy. Useful to know this. I guess I will wait to buy them.

    You're a lot more forgiving than I am. I really hate hard drive failures, because they take so long to recover from. It's the worst type of failure in my opinion. And also, because I'm stupid and go a few days without doing a proper backup sometimes. So, for hard disks, I value reliability more than any other part (except maybe the power supply, which tends to screw up a lot of things further down the food chain).

    The replacement policy shows that Samsung doesn't quite get it. They don't seem to understand how important reliability is, or how important it is to get someone up and running again as quickly as possible. I always carry a spare or two if it's for a RAID array, but Samsung is selling these to residential people too, and no one likes being without their computer, and they aren't going to keep spare hard disks.

    It's not that I'm forgiving, its more that I've excepted the fact(or at least high probability) that any hard drive I buy today, from any manufacturer, will fail. Maybe tomorrow, maybe the next day, maybe 5 years from now.
    So as a consequence, I am extremely diligent about backing up my data. I use both RAID and a backup service from mozy.com for the most important data.
    Also, I hear a lot of talk about how "Maxtor sucks!" or "Seagate sucks" or "<insert manufactuer> sucks!". The simple fact of the matter is: Without factual data from the hard drive makers themselves, there will NEVER be any method of determining which hard drive manufacturers are the most reliable. And none of them will ever produce that data for obvious reasons.
    Case in point: I've had more hard drives than I can even remember in the last 15+ years, and I truly can't think of "the best manufacturer". Every time I've thought I had a great series of drives, I had failures at some point that made me rethink it. So...... backup, backup, backup, and go with the company that provides the best warranty, service, etc. Which, IMHO, ain't Samsung.

    Well, you have some factual data from Seagate, look at their warranty.

    Hard drives can fail, but I have had none from Seagate fail, and this included drives over 5 years old, actually, some over 10. And this goes back to the ST-255 and ST-251, although you'd have to low level them every few years because they were steppers. Crashtors I never bought, but they were so widely recognized as bad, it was way past anecdotal. IBM's drive problems were also not anecdotal, they were widely publicized and even recognized by IBM. Western Digital's were similar, although I don't remember exactly what Western Digital did to fix it. I had bought two of their drives around that time, and both died as well. So, it's not just people blabbing, some of it is very clearly bigger than that. I have never seen Seagate get into that situation, and they sell a lot of drives.

    I actually did have a Seagate fail, but it was some 10K monster made in the 1990s, and it was left in a garage for about three years. I can't really blame it for that, it probably got stepped on and kicked and slept on by a raccoon. But, it worked before it's garage experience. Having used well over 200 Seagate hard drives over the years, just my own, not for a company, that's not a bad success rate, especially since the ones in my main machines I don't change often. The one on this machine is from 2001, and doesn't make a sound and is on 24/7. Try that with a Samsung.

    I do agree, back up early and often. I forget to sometimes though, I wish I didn't, but I do. You really have no control over it, it can happen any time, so the only way to address that truly is to make sure the impact of it happening is limited. But, I'm a moron, I don't do it as often as I should, and I just don't seem to be able to get into the habit of it.

    I am not too impressed with the Hybrid drives and Vista right now. ;) We will have that review up next week. Reply

    How do I read the full blurb? On the main page, I see
    quote:

    "Our first look at Samsung's latest SpinPoint T166 drive reveals a quick and affordable drive... oh yeah, did we.."

    but I can't find anywhere that shows the remainder of the text. It's not anywhere in the article.

    If you click on the storage header that will take you to a page where you can see all the intro text for those articles - same goes for the other areas, of course. Not like it really matters much, does it? Reply
