  1. Any comments on how the 1TB Seagate 7200.12 and Hitachi 7K1000.C stack up against each other in terms of performance and noise? I'm coming from the WD 640GB Caviar Black camp and the above 2 are my available choices.
  2. Thanks for the explanation! Is there a hard drive brand that is least affected by this? Or is it pretty much the same outside of WD?
  3. I've read you have to use the WD TLER utility so that Caviar hard drives can be used in RAID, and that more recently produced Caviar hard drives do not allow the utility to be used. I'm looking to put together a simple RAID1 with RAID integrated into the motherboard chipset (e.g. Intel G45, or AMD/nVidia chipsets for AMD). 1. Does this TLER issue only affect WD Caviar hard drives? I don't seem to see any fuss over TLER with the other hard drive brands. 2. Does TLER on the hard drive only become an issue with hardware RAID, or is it also an issue with RAID integrated into the motherboard chipset?
  4. The WD single-platter 500GB drive has a 15ms+ access time. I was hoping it was due to AAM being enabled and I could simply disable it, but AAM can't be controlled on this drive and the seek sound indicates its already disabled anyways. Do the single-platter 500GB drives from Seagate and Hitachi do any better? I've found the 2-platter 1TB Hitachi to have sub-standard access times as well.

    The Fall of StorageReview

    Hosting is cheap (and only gets cheaper). With the ads being displayed, a site like this should still be cash-positive.And the message board is still here.
  6. They share the same driver. I believe the PERC 5/i is an add-on adapter while the SAS 5/iR is a motherboard-integrated solution. Why is it so bad? And is this the case even with their latest ICH10R?
  7. It's the "Dell SAS 5/iR Integrated Controller" The SATA connections for this controller are on the motherboard. I figure it's hardware-based and probably better than the RAID built into the Intel chipset? But the Intel probably has more frequently updated drivers. Oh yes, and it's a Dell Precision WorkStation 690.
  8. I have a Dell Precision workstation with an Intel server motherboard. It has a Dell SAS RAID Controller as well as the Intel RAID that's built into the Intel motherboard chipset. I thought a SAS controller was only for SAS drives, but apparently it works with SATA drives as well. For RAID 1 with two WD Black 640GB SATA drives, which controller should I use?
  9. Yes, drives of the same model can have differing performance characteristics. Of the 4 WD6400AAKS I've tested for STR, one was faster, two were about tied in the middle, and one was slower. Perhaps normal variance of motor speed (i.e. they don't spin at a perfect 7200rpm) or different brand motors were used.
  10. Seagate drives haven't supported AAM for a long time. If you read back far enough, it has to do with something along the lines of a patent/royalty issue. Their drives come hard-set in either performance (equivalent of AAM off) or quiet (equivalent of AAM on) modes. Typically, Seagate PATA drives are shipped in quiet mode and SATA drives in performance mode. There are exceptions like the Seagate slim/single-platter SATA drives, which also come in quiet mode.
  11. Looks promising! How does the noise level compare to the WD6400AAKS? And do you have AAM on or off on the WD? I assume this Seagate SATA drives is like the rest in that it does not support AAM.
  12. 4 instances is the limit on my WD6400AAKS and nVidia nForce610i chipset in AHCI mode. Anything past that and some of the instances will remain at near-zero instead of alternating between peak and zero.

    WD HD "Protective Head Parking"

    I always thought that when you made changes to the AAM or APM setting, it was stored in the hard drive and remains at that setting until you change it. Makes me wonder if the Dell BIOS is resetting it at POST.
  14. Western Digital 640GB WD6400AAKS nVidia Geforce7050/nForce710i chipset w/AHCI enabled in BIOS, nVidia SATA-IDE v10.3.0.21 driver with NCQ enabled: One instance: 112MB/s Two instances (0%, 50%, 256K block) 1st instance: 112MB/s peak 2nd instance: 93MB/s peak Graph line hops up and down like the screenshots you just posted. Average jumps around all over the place so taking the number that's displayed when 1 minute is up isn't so useful (it changes signficiantly depending on whether that particular instance is currently at peak while the other is not). Would probably have to run the benchmark for much longer for the averages to smooth out. But I'm just going to assume that with 2 instances, the average is roughly half of peak for each instance. So it looks like we can add the WD6400AAKS to the list of drives with proper NCQ implementation. PS My first test run was in a different system with nForce4 chipset, which apparently does not support NCQ even if it is enabled in the driver.
  15. WD6400AAKS Western Digital 640GB HD Speed, 2 instances (0% and 50%), 256k blocks With NCQ on, speed is maintained at 110MB/s but alternates between both instances every second. So when one instance is at 110MB/s, the other is at 0MB/s. So the average is still 55MB/s. Is this normal for NCQ? Or should I expect to see a constant 110MB/s for each instance if NCQ is properly implemented?
