Cloud service is very fast. I feel at ease knowing my data is save using Raid 5 as with my EX4 I just swapped a failing drive with a new one and it began formatting it for use. Great for photographers and video pros. Very impressed with my PR4200!

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.

Cloud OS 5 is a JOKE!

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%.

Western Digital will end support to your device
on November 19, 2021
Posted by: afrf107
The software will create problems over time; you need to have a high technical knowledge to get the most out of the device. The worst is investing time and money into the device and having WD end support because is no longer compatible with their security updates. Do not invest in this device. I advise you to build your own NAS (OpenMediaVault or FreeNAS) instead of buying this device; honestly, it is not that hard.

Added PR4100 to EX2100
on October 13, 2021
Posted by: Anonymous
Verified Purchase:Yes
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.
