Customer Reviews for WD - My Cloud Pro PR4100 4-Bay 0TB External Network Attached Storage (NAS) - Black
Posted by: Roger B
Verified Purchase:Yes
This is my second PR4100. I have had a good experience with the first for the last 3 years so I purchased a second after looking at alternatives. WD was able to deliver in 4 days and I stuffed the NAS with 14TB drives run in a Raid 5 configuration. This second PR4100 is essentially a backup of the first. Both NAS systems contain plex media and backup of the family PC data. I have both systems on the same UPS and make use of the network UPS option. Syncing of the systems is done with Resilio Sync.

I own and EX2100 with mirrored 3TB drives. It's getting close to 2.5TB of data so wanted upgrade and provide disaster recovery. Purchased the PR4100 with two 12TB Red Pro drives. The drive set up and move of the data from the EX2100 went well. Also purchased 2 8TB Red Pro drives for the EX2100 that will not be mirrored. This will be placed in my son's home in another state. I will back up my data to the EX2100 and my son will back up his data to the PR4100. This last part of the disaster recovery plan will be put in place in a month so I can't comment on it now.

WD PR4100 -Simple Low Cost NAS's for entire Family
on July 5, 2025
Posted by: Home User
The WD PR4100's are a simple to use, plug and play, NAS, designed for non-technical users with a streamlined, minimal interface focused on basic file storage, backups, and remote access.
They are the product of choice for those users who just need network storage, not advanced server features..
They are typically cheaper than similarly specced systems.
The units can come with drives pre-installed, which simplifies purchasing and setup.

I would recommend this to a friend!

The rapid speed that our new PR4100 works, in relation to the slow speed our old EX4 operated is significant. This is a marked improvement in our NAS requirements.

If you want it for movies, look elsewhere…

If you want it for movies, look elsewhere! Can’t put together good software anymore. OS 3 was stable for playing movies, but OS 5 is horrible! Stutters, freezes and crashes.

WD PR4100
on July 16, 2021
Posted by: Peter
Bought this a couple of years ago. Mainly because of the WD Sync feature which is now longer supported. Disappointing that another business is heading down the path of having to pay for features annually.
Great product, but useless without the right software to do what you need to do.

not good
on August 31, 2022
Posted by: theoiv
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.

Locks up / shutdown randomly every day as if there is a maximum data allowance that has been exceeded. Brand new / updated so what is the problem WD? My disappointment rate for the year is nearing 80%.
