Review: Fantastic NAS Drive - Beware Shoddy Packaging - I've just recently purchased my third home NAS drive (an upgrade/replacement for the first NAS, which I've out-grown). As before, I wanted to use Western Digital Red drives, because they are designed for 24x7 operation in a NAS. My last NAS was equipped with WD Red 6Tb models (5400rpm) and this time I elected to upgrade to 12Tb, helium-filled drives, selling for just shy of £400 each. I wanted 16 drives in total - 8 for the new NAS, 8 for the old (I use RAID6 and wanted 2 spare drives for each 6-bay NAS). I decided to split the order in to 4 - with 4 drives in each - to split the risk in case of transit damage (you don't want to put all your drives [or eggs!] in one box, because if that suffers damage in transit that you cannot see, you run the risk of all your drives failing at the same time...). Please see attached pictures of 2 of the drive deliveries received so far. As you can see from the images, the drives turn up sealed in original packing material from the factory, but with ABSOLUTELY NO SHIPPING PROTECTION WHATSOEVER. These drives will have been thrown around in the back of vans, on trains, who knows what, subject to unknown shock treatments. I've already had to return one batch of 4 drives to desertcart; one of them had a dented top plate and the other 3 failed when I added them to my NAS - clear signs of significant transportation damage. I've asked desertcart repeatedly, through the customer support and returns procedures, to have expensive items packaged more safely. Suffice to say, nothing has changed. These are AWESOME drives and a recommend them unreservedly. However, if you need to buy them mail-order (and to be fair to desertcart, they use multiple different couriers so there is no way of knowing who is going to abuse them in transit), you must 1. Split your order in to multiple batches - don't order one bulk load 2. Split your orders over several days - to avoid the risk that all parcels get put in the same lorry and subject to the same damage 3. Photograph the outside of the shipping box (e.g. smartphone camera) before opening it, ESPECIALLY if you see signs of transit damage 4. Check your drives with painstaking care when you receive them - and be prepared to reject any that don't look like they are behaving perfectly out-of-the-box 5. Put labels on or otherwise mark each drive so that you know which order it was shipped with - that way, if you have a problem with a drive failing, you will immediately be able to work out which other drives came in the same packaging... 6. Be ready to demand replacements or refunds. The only way desertcart and 3rd party resellers are going to learn to pack orders properly will be when people insist on it. Whew! With that out of the way, here's a review... The WD Red drives form something along the lines of a "Prosumer" range of hard drives. These are easily a step up from regular retail drives (say the Green range), but perhaps not quite as robust as their Enterprise range. They are priced a little bit more than competitors from companies like Seagate (who have the IronWolf range), but they perform MUCH better. Don't take my word for it; web search for the "Backblaze" review of hard drives - that is the definitive reference for drive performance... These 5400rpm drives may not have the rotational speed of the 7200rpm "Pro" siblings, but are priced accordingly - and offer almost-as-good performance. In fact, you can offset the speed difference by selecting a good RAID configuration and using a good NAS. For:- 1. Very well made; truly excellent, reliable build quality 2. Very quiet in operation, moderate but not excessive heat output when running hard 3. Excellent long-term data retention; my oldest Reds now 7 years old and going strong, ZERO faults Against:- 1. Pricey in comparison to the competition. Sum-Up:- You get what you pay for. If you are using these to preserve "your digital life" (in my case, tens of thousands of irreplaceable photographs and hours of recorded video content) then what price data integrity??? Put simply, if you are storing data that is materially or sentimentally valuable to you, then you would be crazy to go with anything less than the best drives you can afford.
Review: Great quality 5400rpm NAS/Backup category 6TB hard drive that works perfectly with my Apple Time Capsule - It's important to mention that it is still early days but so far the WD Red 6TB has done nothing but impress. The NAS/Backup designated hard drive displays great build quality and its performance is impressive. I purchased it in order to upgrade my 4th Gen Apple Time Capsule (model A1409) which went without a hitch. Once the hard drive was installed a quick visit to the Mac's AirPort Utility program allowed me to erase and format the disk which was then recognised perfectly as a 6TB time capsule drive. The hard drive runs quietly, comfortably cool and smoothly, having consistently backed up 2.5TB of encrypted data in two and half days which, for those that don't use Mac's or time machine, is a very reasonable speed transfer rate (Time Capsule is NOT a fast device). I purchased the 'component boxed' version of the WD Red 6TB drive and registered the hard drive via Western Digital's website for 3 years extended warranty without any problems. Whilst it's not a big issue for me (as the Time Capsule's WiFi connection method bottlenecks data transfer) the read and write speeds appear excellent for a 5400rpm drive with such a large storage size. I haven't found any reason for complaint and, having used WD drives previously (as well as many others), I'm optimistic about the WD Red drive's future performance.

## Questions & Answers

**Q: Is the warranty 12m as stated by amazon (which they also confirmed by email to me) or 3y as normally offered by WD?**
A: Just a point of note - I had one of these very recently replaced under warrant by WD after 20 months - they sent me a replacement after a couple of weeks - but you should be aware they send recertified drives and not those with the WD red stickers but recertified stickers - so you get lower grade drives from WD under warranty

**Q: NOTE:  These are shipping without the three year warranty.  WD website says 'OUT OF REGION'.**
A: Just to confirm that the OEM drives sold by Amazon only have a 12 month warranty. Western Digital Support are refusing to honour the 3 year warranty on a drive I purchased directly from Amazon (Amazon EU S.a.r.l.) in September 2015. BUYER BEWARE!

**Q: Why is only 1.99TB available? I can't allocate the rest.**
A: It depends how the drive has been partitioned. To see the full size of the drive with one partition you need to partition the drive using GPT. You can then format it with NTFS, EXT or whatever you fancy. Alternatively you can use the traditional MBR partitioning style and allocate a maximum of 2GB to each partition.

**Q: Is this drive okay to use in a PC, or only in an NAS?**
A: Perfectly fine to use in a PC, it's designed for continuous use hence why it's targeted at the NAS

### ⭐⭐⭐⭐⭐ Great quality 5400rpm NAS/Backup category 6TB hard drive that works perfectly with my Apple Time Capsule
*by L***R on 29 January 2018*

It's important to mention that it is still early days but so far the WD Red 6TB has done nothing but impress. The NAS/Backup designated hard drive displays great build quality and its performance is impressive. I purchased it in order to upgrade my 4th Gen Apple Time Capsule (model A1409) which went without a hitch.

### ⭐⭐⭐⭐⭐ Perfect NAS drives
*by M***S on 4 June 2013*

Although I haven't had access to the full range of Western Digital's colour-coded drives, I am able to compare the Caviar Reds to Caviar Greens. Both are aimed to have minimal power draw with good capacity, and both deliver with a tiny 4-5W typical, both are available in 3tb capacities, and both will deliver solid transfer speeds for large files of around 150mb/sec for a continuous transfer of a single large file (no fragmentation). However, the Reds are intended more specifically for NAS use, and while the justification for the extra cost is no immediately apparent when looking at the numbers, the big difference with the Red drives is that they are far more responsive (much lower average seek time) than Greens, making them ideal for accessing lots of small files, or for working in a shared environment, which will bog down the Green drives. Also, unlike the Green drives the Reds are designed to spin continuously and avoid parking the read/write heads, while still retaining the same low power consumption, while the greens will attempt to rest components in order to achieve the same results for lower cost. The result however is that a Green drive will be less efficient if it is actually under heavy load, and will suffer greater wear on its components in such cases. Which brings me neatly to the final factor, and the one that truly convinced me; the three year warranty. If you're going to be using as a backup device then the last thing you want is a drive with a poor warranty, for something so sensitive I believe it's better to spend the small amount of extra cash for the extra peace of mind, even if it's just to know that you won't have to shell out if the drive does fail. So to conclude; even for non NAS use I would probably spring for more Red drives so long as they remain only slightly more expensive, however the difference in price does waver, so your choice may not be as easy, but if it's close enough, or you know you need reliability under heavy use, then the Reds are the drives to get.
