Excellent System drive
on December 30, 2022

Verified Purchase:Yes
I have found buying the 4 drives and installing them in the enclosure to be very fast and easy. Hard to get it wrong and it allows buying better quality drives at a much cheaper price than the bundled ones. The drive is extraordinarily stable and the RAID 5 configuration maximizes space. I have used the USB backup and PLEX apps and found them to be useful and work well. My next foray will be into the iTunes app which will definitely make access to my iTunes library simpler and not dependent on the app being open in the computer. Great media center

Moved 4x10TB drives from my old EX4100 without a problem. Took the new PR4100 about a day to recreate the MyCloud links

Very Satisfied with the PR1000
on December 14, 2022
Posted by: splat_147
After about 6 years of use I had to replace my DL4100 because I encountered the Intel Atom C2000 bricking issue. I moved my 4 disks from the bricked DL4100 to the PR4100, said OK at the roaming raid prompt and my RAID 1 mirrors, data and configuration were intact. Very easy to migrate to the newer NAS using the same disks. I was thinking of upgrading to a newer unit; but this forced my hand. I would recommend the PR4100; if it last 6+ years I'll be even happier.

Reliable, easy to use, NAS and Plex Server
on November 14, 2022
Posted by: toddgeo
I've had my WD My Cloud for almost 4 years now. I upgraded the ram as soon as I got it, with the intention of running my Plex Server from it. It was easy to install Plex and get all my media folders uploaded and set up. I have had to replace one drive after a power failure, but the replace went exactly as a raided drive replace is supposed to go.

not good

Worked fine until I did an update. After that it never booted up again. the only indication that it was on was the flashing blue power light. This went on for about four hours until i pressed the power button. The unit immediately shut off, Not a shutdown. To this day, the unit will not boot up. all 32TB's were lost. thank GOD I built a experimental OPEN MEDIA VAULT to play around with as a offsite back-up option. I backed-up my most critical data 14TB"s as a throughput test. That action alone saved my bacon.
Don't trust these devices as a main storage unit. The OS is unfinished and rushed. Build your own OMV or freenas unit using WD drives.

A good product with excellent technical support.

Verified Purchase:Yes
This is the third WD NAS I have purchased. The first being an EX4, which I never felt was adequate, but it worked well enough over eight years ago. I then, four years later, purchased a PR4100 and relegated the EX4 to my backup to my PR4100. Well, the EX4 was no longer serviceable, and basically quit working, so I bought this PR4100 to replace the EX4. These PR 4100’s work so much better than the EX4 ever did. And while I put off upgrading to WD OS-5 for as long as possible, to allow WD to work out the bugs, I did upgrade about six months ago, and it seems quite stable and user friendly. I keep little to no files on my computer, but run the primary NAS as my C Drive in RAID 10, and then do a synchronized back up that NAS onto a second NAS, also in RAID 10. My data isn’t worth the storage devices I have on them, but there should be a slim chance that I should ever loose what I have using this arrangement. WD is THE BEST for helping resolve any problems I have ever had with any of these NAS units, and I use Red Drives in the bays, and knock on wood, they have held up great so far. I don’t use PLEX or any other APPs other than my backup APP, so I cannot give you any information on that, but I do regularly use the remote APP on my iPhone/iPad, and OS-5 and the newest APP work quite well, with few failures to connect, which was very common on OS-3 with the older APP.

You owe me a free hard drive EX4
on April 19, 2022
Posted by: WILDWILLIE
AS I said before my ex4 was upgraded to only work on the local network. Red light on and drive degraded. Ordered a replacement drive and went to install after recreating logins (a pain) and found that drive OK and EX4 rebuilding. You owe we me a harddrive which I have now as a spare. NO WHERE DOES THE UPGRADE SAY IT WILL CAUSE ALL THESE PROBLEMS. LOGINS MUST BE RECREATED. RED LIGHT ON DRIVE 1 COMES ON AND SYSTEM DEGRADED, Overall a bad update causing lots of trouble and yes I rebooted a couple of times and red light on drive 1 was on after about 3 minutes
NOTE I AM RAGING ON THE EX4 UNIT AND NOT ON THE PR4100.
THE GOOD THING IS ACRONIS FOR WD WORKS GREAT
NO WAY I COULD FIND EX4 TO COMPLAIN ABOUT
