Description
The My Cloud PR4100 4-Bay NAS Enclosure from WD features four bays that can house your drives as well as a video transcoding engine, which tailors the video quality to the device. The My Cloud PR4100 provides you with a variety of downloadable apps to create a streaming HD media server with Plex, edit and share content with cloud services, and set up a surveillance system with Milestone Arcus. WD has armed this NAS enclosure with a 1.6 GHz quad-core Intel Pentium N3710 processor along with 4GB of DDR3L RAM to manage your data and configure the drives in a RAID 0, 1, 5, 10, or JBOD array. Having access to four drives, you can set them up in RAID 5 or 10, which enhances the drive’s performance while providing redundancy for your data.
This NAS enclosure is outfitted with two Gigabit Ethernet ports and dual power ports to provide continuous access to your files, photos, and other content. Other notable ports included with the My Cloud PR4100 are three USB 3.0 ports that allow you to share devices or back up with external storage drives. Aside from ports, it comes with SmartWare Pro software and supports Time Machine for a quick and effective solution to create a continuous, automatic backup system. Furthermore, password protection and AES 256-bit volume encryption are on board to protect sensitive files.

WD retired my previous model — prematurely and offered a paltry credit — saying it would no longer be supported despite functioning reliably. But they’ve hooked me on the system and it works well for a double back-up system to hold my large music file collection. Easy to transfer the files and even Apple Music playlists. Works a charm.

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.

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

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.

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.

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.

I upgraded from a EX Ultra2 after 6 years because one of the drives was about to fail. Very easy to use and setup. Works well. Never could get antivirus to work on Ultra2, same here. I mostly use to store photos. WD app is ok for what I use it for. Overall recommended.
