3.5-Inch High-Performance Hard Drive for Desktop NAS Systems

The Deskstar NAS hard drive is a 7200 RPM 3.5-inch hard drive that provides an exceptional blend of reliability and performance, making it an ideal solution for consumer and commercial desktop NAS systems. This NAS-ready hard drive from HGST delivers media transfer rates that are as much as 20% faster than 5400 RPM drives and seek times less than 12ms. Furthermore, Deskstar NAS hard drives incorporate a rotational vibration sensor and achieve reliability of one million hours MTBF.


Key Features
  • 7200 RPM performance
  • Up to 4TB capacity
  • 1 million hours MTBF
  • 6Gb/s SATA interface
  • Rotational Vibration Safeguard (RVS)
  • No additional hardware required

Colossal Capacity Meets Award-Winning Performance

The Deskstar NAS comes available in storage capacities up to 4TB for room to grow as your networked content grows. This HGST hard drive runs at a speedy 7200 RPM, with a 64MB cache buffer for fast data access. SATA III provides up to 6Gbit/sec data bandwidth rate for rapid file transfers and backups.

One of the greatest hindrances to hard disk performance is vibration. Like a needle on a record, the disk drive’s head must try to follow narrow data tracks in order to read (or write) information. These problems are particularly acute in multi-drive systems, because drives tend to be installed alongside each other, in arrays. The vibration caused by the rotation and seek activities of nearby drives can affect the whole array, progressively disturbing the operation of each drive in the system. The drop in performance can be significant. That's why the Deskstar NAS hard drive has an advance Rotational Vibration Safeguard (RVS) that anticipates disturbances and counteracts them, maximizing performance in the most arduous conditions. If the RVS sensors feel a vibration rippling through the drive, they send a signal to the actuator that controls the head’s position. The actuator then compensates for the disturbance, counteracting it with an equal and opposite force. In this way, the head is able to "ride" the vibration and stay on track, helping to prevent data loss or corruption.

Outstanding Reliability

All HGST hard drives are designed to the highest quality standards with field-proven components. With one million hours of MTBF, a rotational vibration sensor, and 24/7 availability, the Deskstar NAS hard drive is an ideal choice for backing up and sharing content at home or at the office.

The Deskstar NAS system is compatible with both Windows and Mac desktop PCs. Windows users will need a computer system running Windows Vista/7/8/8.1 and an available SATA port. Macintosh users will need a Mac computer running OS X 10.5 or newer and an available SATA port. The package comes with everything needed for installation, with no additional hardware required.

This is made by Western Digital, and I've always had nothing but praises for WD drives.
For Real
Only time will tell whether these drives will be reliable, but with none DOA they're off to a good start.

Noise level is low and heat is about average (always recommend fan cooling for any storage drives).

As an IT engineer I've long been impressed with the durability of Hitachi drives. I currently have several 3 TB Hitachi drives running in my NAS. They have run 24/7 for more that four years without a single fault of any kind, as determined by S.M.A.R.T. data which I download every two months. In a Backblaze (cloud storage provider) blog they compare their experience with about 30,000 hard drives. Their Hitachi drives substantially out last others, especially Seagate and Western Digital.

Size Name: 3TB
First HGST brand drive I've bought due to the price per size. So far they have been good, quiet and no smart issues.
I will say they do start out fast but once filled up 75%+ they tend to slow down quite a bit which for a 64MB cache drive they could be faster.

I have 5+ year old Seagate drives which at the same fill rate are actually faster then the HGST NAS so that is a disappointment.

I've bought nothing but WD the past 5 years but the SE and RE drives are much more expensive, run hotter and consume more power but do have a better warranty so I took a chance with HGST.

Here are some benches I did when they were new and I was testing them out in different configurations.

Intel controller:
Sequential Read : 157.234 MB/s
Sequential Write : 152.631 MB/s
Random Read 512KB : 80.351 MB/s
Random Write 512KB : 97.059 MB/s

Marvell controller:
Sequential Read : 153.575 MB/s
Sequential Write : 149.040 MB/s
Random Read 512KB : 75.959 MB/s
Random Write 512KB : 92.840 MB/s

Intel controller raid0
Sequential Read : 529.409 MB/s
Sequential Write : 285.578 MB/s
Random Read 512KB : 503.219 MB/s
Random Write 512KB : 183.240 MB/s

Intel controller raid1
Sequential Read : 167.987 MB/s
Sequential Write : 163.000 MB/s
Random Read 512KB : 56.932 MB/s
Random Write 512KB : 78.967 MB/s

HDtune:

Minimum 85MB
Maximum 164MB
Average 129MB

Access time 15ms

Burst 313MB

As you can see in raid0 [or raid10] these drives can really haul, course bear in mind they were empty and you will not
see such numbers as you get over 50% full.

Just what I was looking for, reliability. Obviously a 3-year warranty is a good indicator. The Deskstar NAS is a new product. It has the 1M MTBF vs. the regular Deskstar 7k4000 (HDS724040ALE640) which has a 0.8M MTBF. The NAS version also has a rotational stability sensor to help monitor the smart status better. I was looking for additional external storage for backups & videos. I installed 4 of these in an 4-bay external USB 3.0 enclosure (Dyconn Quartz 4). For around $1100 total installed cost, you can get nice 16Tb setup for all your "stuff". I've got mine connected to a MacMini. A good (non-SSD) 3.5" drive has about the same read/write speed as USB 3.0, thus in an external USB 3.0 setup, it will give you ~170-180 MB/s regardless of RAID setup.

Update #1
I was able to test drive speed vs various other drives. This drive performs as expected. I did not test in a RAID configuration. (sorry about the formatting, the last two nos. in each row are Read/Write in MB/s), all tests with BlackMagic

I bought four of these drives and put them into a Promise Pegasus2 R4 with RAID 5. With this setup I benchmark about 470 MB/s write and 360 MB/s read with Blackmagic Disk Speed Test. These speeds are well in excess of the speeds you will be able to achieve with a NAS, the marketed purpose for the drives. Only time will tell whether these drives will be reliable, but with none DOA they're off to a good start.

Other than using an SSD, this is by far the fastest drive I have ever had, that said I purchased it for its size and reliability. Size is great, speed is awesome. The jury is out on reliability for me, maybe I'll revise this in two years!.

I like to retire my drives after a couple of years to head off reliability problems before they happen. I am in the process of using this drive to replace two 2TB drives from another manufacturer. I lost a drive on a laptop a few years ago and ever since I have become very paranoid about loosing my data (basically everything that I have made for close to 20 years, plus many movies, songs and pictures, I delete NOTHING).

If you have read a lot of Hard Drive reviews, you are probably more worried about which drive to pick now then when you started. After several weeks of research and reading, HGST seemed to me to be the best choice. Time will tell.

Assuming this drive works well over the next few months, I will purchase a second one and mirror them for data backup.
