Western Digital 16TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5 - WD161KFGX

72 TB Raid 5 because I really dont want to insert a 4k blu ray disk into anything more than once.

I purchased the 4T version for home PC with a windows operating system. I need this particular HDD because it is listed 7200RPM. I didnt meet any challenge when I installed other WD hard drives. It involved only a few clicks when I switched from WD 1T to 2T months ago, for example. I simply inserted the new disk into a USB case and cloned the entire disk in Minitool participation and got the job done. I was not lucky with this disk. It gave me so much trouble and wasted my two days to figure this out. First, sector size was different from my old 2t WD Blue drive thus I couldnt clone it directly. Because the target drive was not the main OS drive so I decided to simply copy all the folders into the new HDD and switch the two. Then I used Minitool to format it. It refused the command, software reported error. I then tried all other software including the one recommended on WD website (Acronis True Image for Western Digital). I finally got it done by using EaseUS. I formatted it and copied all folders from the old disk and switched it with the old internal disk. When I opened windows, none of the partitions created in EaseUS showed up. HDD showed up in BIOS menu so I knew it was there. I googled answer to this problem, read all articles to educate myself. Checked Manage disk in OS and realized one of the partitions was listed as GPT protective partition. I then followed the article published on Seagate website (ironic) and cleaned the entire disk using diskpat command. All data were removed. I returned to day 1. If your partition software doesnt work in Windows, check whether this disk is GPT protective in disk management. Dont repeat my mistake. I am glad I didnt do anything harmful to the old drive thus I spent the second day repeating what I did before, copy and paste. Now the new drive works and it works faster than old WD blue 2T. It is quite noisy but not scary. I am satisfied with the product so far but I hope WD can improve the product to meet various needs from customers. I am not a tech guy but switching HDD shouldnt be so difficult and time-consuming, thus I removed one star (should have been two stars when I felt frustrated yesterday).

This is a review for a drive that was purchased from Amazon and fulfilled by Amazon. I received a new drive in new (sealed) packaging. It was exactly as expected. I was able to verify the 5-year warranty with Western Digital and register in online. I have installed it in my system and it is working correctly so far. Should that change, I will update this review. I cant speak for other sellers in the marketplace, but as I stated... I got from Amazon exactly what I ordered.

First comment: Typical Amazon Quality Service. So far WD4TB Pro bare hard drive is absolutely quiet, vibrationless, super easy to initialize then format to ExFAT and only slightly warm to the touch. Hooked it up with a Unitek IDE/SATA to USB C 3.0 Adapter for now before mounting in stand alone case. Been using WD drives for a number of years so expect this new one will be as durable as the last.

First things first. This 2TB Red Pro drive is CMR (not SMR) technology, which is a relief. In any event, I installed these drives (2 of them) in my quite old, Synology DS211 NAS and thus far have had no issues at all. Pretty happy with them. I havent done any performance testing and this is just an occasional use device, largely for archival storage. I did upgrade to Synology DSM 6.2, no problems there either. All the drive features seem to work including sleep mode and S.M.A.R.T and other drive management technologies. Im mostly happy these drives were not SMR, that was my biggest concern. As far as noise, when these drives are spinning they are pretty darn quiet... literally cant hear them at less than 3 feet from my head. They do make some interesting noises when going into sleep/wake mode however.. very bizarre sounds. Vibration seems non-existent as well. I did have some older WD drives in this NAS for almost 8 years and they seemed to occasionally have some harmonics, these new Red Pro 2TB drives dont seem to have that issue at all. Good luck!

These are the only drives I will ever use for my NAS. Rock solid.

Cumple con lo indicado

This drive worked perfectly upon installation and Ive had no problems with it in over 2 weeks. Im using it for Time Machine backups via an external disk attachment on a 7 year old Mac. Time Machine runs about once an hour. However, I noticed that some reviewers are complaining about the noise on this drive and I want to use my IT professional background to give some insight into what might be going on for them so that others can make an informed decision on this drive. I have the 2 TB drive. I dont personally find this drive to be loud and its running in an external disk drive enclosure. It runs about once an hour for however long Time Machine needs to run. When the drive is in use, it does make some noise, but it cant be heard at all outside of the room its in. I sleep in the room next to where it lives and both rooms are always open and Ive never had this drive make enough noise to be heard beyond maybe 7 feet from it and it can barely be heard at that distance. So why are some people complaining rather bitterly about how loud this drive is? First of all, its an old school mechanical drive. It will make some noise when in use. That is the nature of these drives. And the more you use them and the more filled up they get, the more likely they are to make some noise on use. It is also possible that some drives off the manufacturing line are better than others, some are worse, and some of the people who complain just by bad luck got a noisy one. I dont find the noise Im hearing to be unusual for this type of drive. Ive heard a lot worse. Also, if someone is going to use this drive with a lot of file deletions and additions, its going to make more noise. My suggestion for people who are extremely noise sensitive is to consider paying more and using SSDs instead. They wont make any noise. This drive has worked exactly as I intended it to work and I would recommend it to others. Again, please note that this is a mechanical drive and its lifespan is expected to be much lower than that of an equivalent SSD. You should probably think about replacing it after 3-4 years whereas for a 2 TB SSD, ,in theory you could get decades of heavy use before it goes bad. Thats why SSDs cost more.

I use a good handful of these drives in a few different NAS units. They infrequently fail and are reliably running 24/7/365. I started with 6tb drives. If I were starting fresh I would probably use slightly larger drives. I don’t know if the larger drives are less reliable or the same, but I have been very satisfied. Never forget that RAID is not the same as a backup and you will never lose a byte.

Perfect
