HGST Deskstar NAS 4 TB Reviewby Ganesh T S on November 22, 2014 2:00 PM EST
The traditional market for hard drives (PCs and notebooks) is facing a decline due to the host of advantages provided by SSDs. However, the explosion in the amount of digital content generated by households and businesses has resulted in the rapid growth of the SMB / SOHO / consumer NAS market. Hard drive vendors have jumped on to this opportunity by tweaking the firmware and manufacturing process of their drives to create lineups specifically suited for the NAS market.
We have already had comprehensive coverage of a number of 4 TB NAS drives and a few 6 TB ones. One of the drives that we couldn't obtain in time for our initial 4 TB roundup was the HGST Deskstar NAS. After getting sampled last month, we put the 4 TB version of the HGST Deskstar NAS through our evaluation routine for NAS drives. While most of our samples are barebones, HGST sampled us their retail kit, which includes mounting screws and an installation guide.
The correct choice of hard drives for a NAS system is influenced by a number of factors. These include expected workloads, performance requirements and power consumption restrictions, amongst others. In this review, we will discuss some of these aspects while comparing the HGST Deskstar NAS against other drives targeting the NAS market. The list of drives that we will be looking at today is listed below.
- HGST Deskstar NAS (HDN724040ALE640)
- WD Red Pro (WD4001FFSX-68JNUN0)
- Seagate Enterprise Capacity 3.5" HDD v4 (ST4000NM0024-1HT178)
- WD Red (WD40EFRX-68WT0N0)
- Seagate NAS HDD (ST4000VN000-1H4168)
- WD Se (WD4000F9YZ-09N20L0)
- Seagate Terascale (ST4000NC000-1FR168)
- WD Re (WD4000FYYZ-01UL1B0)
- Seagate Constellation ES.3 (ST4000NM0033-9ZM170)
- Toshiba MG03ACA400
- HGST Ultrastar 7K4000 SAS (HUS724040ALS640)
Prior to proceeding with the actual review, it must be made clear that the above drives do not target the same specific market. For example, the WD Red and Seagate NAS HDD are for 1- 8 bay NAS systems in the tower form factor. The WD Red Pro is meant for rackmount units up to 16 bays, but is not intended to be a replacement for drives such as the WD Re. Seagate Constellation ES.3, Seagate Enterprise Capacity v4 and the Toshiba MG03ACA400 which target enterprise applications requiring durability under heavy workloads. The WD Se and the Seagate Terascale target the capacity-sensitive cold storage / data center market.
The HGST Deskstar NAS is supposed to slot in-between the WD Red and the WD Red Pro. It doesn't specify an upper limit on the number of bays, but mentions only desktop form factor systems. Like other NAS drives, it is rated for 24x7 operation and includes a rotational vibration sensor for increased reliability.
Testbed Setup and Testing Methodology
Our NAS drive evaluation methodology consists of putting the units to test under both DAS and NAS environments. We first start off with a feature set comparison of the various drives, followed by a look at the raw performance when connected directly to a SATA 6 Gbps port. In the same PC, we also evaluate the performance of the drive using some aspects of our direct attached storage (DAS) testing methodology. For evaluation in a NAS environment, we configure three drives of each model in a RAID-5 volume and process selected benchmarks from our standard NAS review methodology. Since our NAS drive testbed supports both SATA and SAS drives, but our DAS testbed doesn't, only SATA drives are subject to the DAS benchmarks.
We used two testbeds in our evaluation, one for benchmarking the raw drive and DAS performance and the other for evaluating performance when placed in a NAS unit.
|AnandTech DAS Testbed Configuration|
|Motherboard||Asus Z97-PRO Wi-Fi ac ATX|
|CPU||Intel Core i7-4790|
|Memory||Corsair Vengeance Pro CMY32GX3M4A2133C11

|OS Drive||Seagate 600 Pro 400 GB|
|Optical Drive||Asus BW-16D1HT 16x Blu-ray Write (w/ M-Disc Support)|
|Add-on Card||Asus Thunderbolt EX II|
|Chassis||Corsair Air 540|
|PSU||Corsair AX760i 760 W|
|OS||Windows 8.1 Pro|
|Thanks to Asus and Corsair for the build components|
In the above testbed, the hot swap bays of the Corsair Air 540 have to be singled out for special mention.
They were quite helpful in getting the drives processed in a fast and efficient manner for benchmarking. For NAS evaluation, we used the QNAP TS-EC1279U-SAS-RP. This is very similar to the unit we reviewed last year, except that we have a slightly faster CPU, more RAM and support for both SATA and SAS drives.
The NAS setup itself was subjected to benchmarking using our standard NAS testbed.

cen - Saturday, November 22, 2014 - linkBought 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.
Laststop311 - Sunday, November 23, 2014 - linkI 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.
Laststop311 - Sunday, November 23, 2014 - linkMaybe 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
cen - Sunday, November 23, 2014 - linkYou only use a single one, I have 4 of these. This is a big difference.
ddriver - Sunday, November 23, 2014 - linkWell, you do have an even number of disks, arrange them the right way and their noise will cancel out ;)
melgross - Sunday, November 23, 2014 - linkThat would be nice, if it actually worked.
ddriver - Sunday, November 23, 2014 - linkYeah, 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.
Zertzable - Sunday, November 23, 2014 - linkIs that why datacenters are so quiet? ;)
jota83 - Monday, November 24, 2014 - linkI am getting 60 of those by the end of the week :) Let's see how they perform within a JBOD (Quanta M4600H)
NightShade00013 - Saturday, January 16, 2016 - linkI 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.
