Performance - Raw Drives

Prior to evaluating the performance of the drives in a NAS environment, we wanted to check up on the best-case performance by connecting one of them directly to a SATA 6 Gbps port. Using HD Tune Pro 5.50, we ran a number of tests on a raw drives. The following screenshots present the results for the HGST Deskstar NAS. Corresponding images for similar drives that have been evaluated previously are also provided in the drop-down box for easy comparison.

    Bought 4 of these for my home NAS and they really are great for the price. The only negative thing is the noise.. I wouldn't have 4 of these in my room for sure.

    I use a 2TB version of this drive in 1 of my pc's and I don't notice any offending noise. The case does have noise dampening foam all around it and the hard drive is elastically suspended and isolated from the frame but I use all noctua fans and a fanless psu so if the HDD was making a lot of noise it should be audible. Maybe it's just your set up. You need to properly suspend the drive off the case with rubber so no vibrations are transferred to the case which is the main cause of noise.

    Maybe the GPU drowns it out but even when the GPU is not in use i still don't hear the HDD even with large file transfers with no gpu activity

    You only use a single one, I have 4 of these. This is a big difference.

    Well, you do have an even number of disks, arrange them the right way and their noise will cancel out ;)

    That would be nice, if it actually worked.

    Yeah, except it would generate extra heat. If the drives operate in synchrony theoretically they could be arranged in such a manner that their noise cancel out, but it be quite the feat of engineering. It would be tremendously easier to simply dampen and absorb the noise.

    Is that why datacenters are so quiet? ;)

    I am getting 60 of those by the end of the week :) Let's see how they perform within a JBOD (Quanta M4600H)

    I just got done doing a burn in with five of these for my FreeNAS and inside a 4U sitting on my kitchen table the fans were louder than the drives by far. The case is a rosewill RSV-L4500, the two rear 80mm fans have been changed out to PWM fans but the 120's are the ones that came with the case. Not that it's loud at all but the drives were the least on my mind.

    Burn test was done with BadBlocks and took about 65 hours to run completely. Running a smart long test now and that is the only thing that is a little different. Drives are ranging from 548 minutes to 582 minutes to complete.

    Got the drives for less than a 4TB WD Red (not the pro version) so I am loving it. Still need to get two more to finish out my pool but RaidZ3 should be great with a set of seven drives.
