    NCQ - Western Digital - What to do.

    The question is: why do you think you need AHCI? AHCI offers NCQ and hot plugging. NCQ is horrible, and nobody on a desktop uses hotplugging. Just disable AHCI, and live happily ever after.
  2. Why would you ever go for the SD over the KS? The SD has TLER (negative), is a bridged SATA design (negative) features an 8-megabyte buffer (negative) and 150 MB/sec interface. The KS is superior in every way for non-server use. 217105[/snapback] So I've made the right choice then! Thanks for the confirmation!
  3. Dammit, I wish I could be certain that TLER can be disabled manually! I just ordered my new computer equipment, and I went for the WD2500KS (S-ATA II features, 16mb cache) instead of the WD2500SD I had in mind first. Which of the two is the faster drive anyway? I would presume the WD2500KS? Or is the WD2500SD a better decision? If I get an answer quick, I can still change my order!
  4. I bought a Western Digital 250gb WD2500KS today. It has S-ATA II features, 16mb buffer, and it beats all of the 7200rpm drives in the latest storagereview benchmarks. And I have good experience with WD
  5. Actually it's not so drastic as the way you put it, it still does the error recovery, but only not so lang as usual. Usually a hard drive will try for example for 15 seconds to recover the sector, while with TLER it will only try for 7 seconds, and then give up. It still does error recovery, only for a shorter time. But, RE drives are more reliable to start with, they are suitable to run 24/7 with a 5 year warranty!
  6. As long as you use them in a raid array of any kind, you're safe.

    Well, you get what you pay for: almost nothing.
  8. Does this apply if the drive is used on a RAID capable controller (nForce4), but not utilized in a RAID configuration? I would like to use one of these drives as a storage disk in a graphics workstation (Tyan K8E, Athlon X2 4400+), but I don't want to risk data corruption/integrity. Thanks. 216747[/snapback] I would like to know this too! I'm just dying to use this drive in a desktop based system, but NOT in a raid array! I wish there was some way to just manually disable this TLER feature!
  9. The WD RE series already kicked ass bigtime (very quiet, very fast, 5years warranty, 1 million MTBF) and the RE2 only makes things better (16mb cache, S-ATA II features, NCQ, 1.2 million MTBF). I think it's a no-brainer!
  10. The way I read it, it sounds like you could get disk I/O errors in cases where the disk could have corrected the error given more time. Unless it's a constantly busy server application I doubt you'd see much difference. 216108[/snapback] Indeed, this is exactly what TLER is about. The PDF that someone links to above, ends with the advice that TLER-enabled harddrives should NOT be used in a desktop environment. I guess I'll just go for the WD2500KS then
  11. Western Digital has 3 ranges of drives targetted at the enterprise environment, namely the Raptor, Raid Edition and Raid Edition 2 drives. These drives all feature very high MTBF times, and a standard 5 year warranty. They are also suitable to be running non-stop 24/7. I was going to buy a 160gb RE drive (WD1600SD) but a certain warning caught my eye: on the WD page, it says this : "IMPORTANT: Because of the time-limited error recovery feature, this product is intended for server applications and is not recommended for use in desktop systems." My question is, how big of a risk is this? This TLER feature brings a little more danger to the table (when you don't use a RAID controller, which I don't), but these drives also have longer warranty, and better MTBF values than the regular desktop drives... (and they perform better too!). So, any advice? Or experience maybe?
  12. Well, according to the two newest benchmark sessions (office & high-end) the Western Digital WD2500KS (S-ATA II, 16mb cache, NCQ) is the best performing 7200RPM hard drive out there. On top of that, it also has the lowest power usage of the tested drives. The numbers/details for these claims can be found in the three links at the bottom of this post. So, is it true that this drive is the best thing you can buy at the moment? It even beats the Diamondmax10 on both benchmarks, and on the power usage test! The reason I'm asking this, is because in the PREVIOUS benchmark session, the WD2500KS doesn't perform so well, it didn't manage to beat the Maxtor drive, while it DOES manage to beat that same drive in the new round of benchmarks! (old benchmarks here: http://www.storagereview.com/articles//200...D2500KS_1.html) Any help appreciated! http://forums.storagereview.net/index.php?showtopic=20450 http://forums.storagereview.net/index.php?showtopic=20478 http://forums.storagereview.net/index.php?showtopic=20507
