Western DigitalWD8003FRYZ WD Gold Enterprise-Class Hard Drive - Hard drive - 8 TB - internal - 3.5" - SATA 6Gb/s - 7200 rpm - buffer: 256 MB - (Components > Internal Hard Drives)

Best hard drive on the market - but worth it if you need longevity and ultiimate reliability. This is the finest drive in the Western Digital Collection, faster than the black, more longevity than the red. Its the pinnacle of HDD technology.

We bought two of these Western Digital WD4002FYYZ 4 TB 3.5-Inch Hard Drives, to populate a NAS system.For those people who may be unclear about a NAS, it is a network-attached storage device, which holds one or more hard disks and connects into your network, giving other devices access to the stored content. This Western Digital WD4002FYYZ 4 TB 3.5-Inch Hard Drive – Gold, is well suited to be used in NAS devise. This drive, in particular, has a storage capacity of 4TB and has a substantial 128MB Cache.The accompanying bumf states “to make sure all of this data is kept safe the GOLD HDD’s are equipped with enhanced RAFF Technology which monitors the drive and corrects both linear and rotational vibration in real time, this along with the Multi-axis shock sensor and StableTrac Technology gives you peace of mind to know your data is safe”.In operation, the drive noise is better than OK and has a rotation speed of 7200 rpm. I must confess I am a western digital user when it comes to getting hard drives, or should I say populating a new NAS system.It is early days yet - nonetheless, I am happy with the Western Digital WD4002FYYZ 4 TB 3.5-Inch Hard Drive so far. I shall update if there any issues, hence my four-star rating.

+ Good price (per gb)+ Reasonable performance+ Good reliability (so far)I always buy Western Digital, I've never had one of their drives fail on me (yet). So I'll quite happily keep buying them!Why go for any of the green/blue/black/red series ones when you can have a gold series. Do it.

This is a datacentre hard drive and with light use would expect at lest ten years use. I have had 8 WD 1TB Desktop SATA Green drives running as raid 6 for 8 years then they were used in other units as non raided drives. As server upgraded in 2011 to 16 2 TB drives. But only time can tell you if you made the right choice.

Arrived quickly.Same reliability as RED PRO but with peace of mind support and warranty. Faster than normal WD REDs and good in NAS of 12 bays.

Took quite a while to get here and then arrived broken out of the box. Tried it in my NAS and the drive wasn't recognised at all - there were some faint clicking noises similar to those you get from a dropped head. Spent a great deal of time on the phone with Synology before coming to the conclusion that the drive must have been DoA. I do have one of these drives in the NAS already which has been fine for 2 years but suspect that the problem with this one might have had something to do with the minimal packaging - no padding or protection other than a thin foil condensation bag and the usual cardboard surround. I would suggest that this is not really good enough for sensitive electrical items. Returned to Amazon without any quibble but rather than a refund, I did need a drive and they were not able to replace only suggest that I buy elsewhere. Not really up to the standard you expect from Amazon.

True test will be longevity. performing as expected so far.

It arrived and looks well made
