LOU C : I own a Promise Technologies Pegasus R2Plus 2 drive NAS bay. They came with Toshiba 3TB 128 cashe  & 7200rpm They didn't last 4 years. I shouldn't have a problem going from 3TB to 4TB should I?RICH U : no. In this case, "size doesn't matter" as long as your Pegasus will support 4TB drives. Look up the specs for it. Just make sure that you follow procedures for exchanging drives so that you prevent data loss.

Excellent Service!

Original drive was sent DOA, but customer service assisted and sent out new drive even before the old one was sent back. The new drive is in excellent condition and functioning properly.

16TB on a Seagate Thunderbolt stand, massive noise

I have a Seagate standup Thunderbolt SATA send where I normally run a 6TB WD HDD for Time Machine. I wanted to upgrade to 16TB but when I turned it on the mechanical noise was massive and it never mounted. Sounded like the disks were going to fly out.I got an RMA but called Customer Support and got lame response that NAS drives are not designed to do this kind of use. (SATA is not SATA???) and suggested I call Seagate support to find out more on my now 8 year old Thunderbolt base. Right... Existing WD 6tb works fine and same 6GBS rated. It would have been nice to be offered a replacement. My main gripe with tech support is how shallow the response like he didn't any real idea of how things work....or not.

Honest Company...

I have used Western Digital all my computer life, I am blessed to not have experienced other companies problem making! I hear from friends, relatives and common conversation what it is like with these drive manufacturers. I tell you the truth you cannot do better than Western Digital thy quality is there in everything they make or your money back. If you are aloof then you can follow directions and figure out what does ail thy drive usually some unknown factor in your build is straining thy drive beyond tolerance if they fail however they are honest, you can get a refund, replacement or tech support.

Fast shipping, good packaging

I got these drives from the weekly sale, they had some website issues but was finally able to get them, I read a lot of reviews that said the packaging sucked, so I was hesitant to buy from here, however, the packaging was perfect.

Still poor reliability in RAID

This is a follow-up to my review about a year ago. Again, my use case is an 8 drive RAID in a Linux system (Fedora). These drives were purchased Nov 2020. I have also since moved from an Adaptec RAID card to a MegaRAID card, to hopefully get a better experience, however, that did not help. I was running these as a RAID 5, but because of the failure rates I have switched to a RAID 6. I have now had 10 of these drives replaced in 8 RMAs (88473645 88545097 88568417 88587158 65073767 65099873 65155823 65162324 65191095). Smartctl is also giving me the tell-tale warning signs that another is now going out (increasing ATA error count). So WD may expect my 11th RMA very soon. The response to my last review, to contact customer support, went no-where. I did as suggested and it seemed to be promising at first. However, I got bounced around 3 different groups and eventually no more replies. Again, these drives appear to do very well as stand-alone drives. But in a Linux RAID, seriously, hands-down the worst drive I've ever had the misfortune to use. And as an IT pro with over 20+ years...I've used a LOT of drives, different types, configurations, etc. I would not ever recommend this drive as a RAID drive. WD customer support on this matter was a disappointment. However, their RMA program is fantastic.

Excellent product

I needed an upgrade to my PR2100 server drives and the WD Red Pros are just the best. They are very well made and are an excellent product, I would buy them again.

This drive is to replace a 1TB which has given me great service, but I needed larger. Hope this lasts as long.

WD Hard drive? Fragile?

I would rather this have shipped in a box vice a mailer envelope. The box was pretty rounded off at the corners. Wholly relying on MFGR packaging doesn't always work well. It's three days in service so I suspect it's going to last.

Excellent for NAS

Tried a Seagate one first, and it failed immediately. Have had good success with WD Red in the past, although sticking to Pro version only because of downgrades on regular Red version

Works like a hard drive should - time will tell how it lasts but WD is good usually

Hard to give a good review after only having it for a week. It's a little noisier than I would prefer, but it seems fast for a standard mechanical hard drive.

Great and super reliable HD for NAS

Bought this Red Pro to replace a faulty drive on my NAS. Went with Pro (instead of regular Red) for the added shock protection and longer (almost twice) rated workload rate (300 vs 180 TB/year). My specific application of NAS will likely not hit that high of workload but the higher rating gives me peace in mind (placebo effect or not, it is my preference to have the highest expected performance for what I am willing to pay, especially if on sale ;-) ).

RELIABLE

Yet to have a WD Red PRO or RED HD fail. Reason for this purchase was upgrading a 3T mirror to 6T mirror. Setting at my desk I can see 24 WD REDs at work. With no HD failures since I switch to WD RED I question my installing raid 6 controller.

Top of the Line but Pricey

These are excellent drives with the durability of NAS and near performance of the Black drives. Fast and quiet. Use the 8TB mainly for backup and the 4TB for RAID. So far no failures going back about 2 years. 5 year warranty. They do run a bit warm but not excessive. The main downside is they are a little pricey.
