WD 16 TB My Cloud Pro PR4100 Professional Series 4-Bay Network Attached Storage - NAS - WDBNFA0160KBK-EESN

Really good the basic set-up is very easy but I needed they're costumer service to help me set 8t up properly and they where indeed very helpful and since then it's been running just fine without any issuesPlex runs quite slow on the TV

I had several requirements that I needed from a device such as this:(1. It (including the HDDs)had to be made by a manufactuer that I know and trust.(2. Needed to have 4 HDDs that can be put in RAID 5 (which it does and then some.)(3. Reasonably compact(4. Can do backing up to a online repository when required.(5. Sensible UI (accessed by web-browser.)(6. Reasonably affordable(7. 32Tbs of storage (16Tbs is usable when in RAID 5 + spare)(8). Capable of at leasr Gigabit ethernet speedsThis item met 7/8 of these requirements - (it's expensive,) I admit, I was nervous when I saw that it came all the was from France. Hiwever, everything was OK when I saw that everything was in English and that it had a UK plug (as well as a two-pronged Euro-plug.)Setting it up took a long time - 12+ hours to put all 4 HDDs in RAID 5 + spare - once done, create a user groupand a user.Done - recommended

Very easy to set up for home based cloud services. We have it set up in a cupboard that houses our tech in our sitting room, just below the TV. When it was first started the fan came on and it was a bit noisy but it soon settled down to a whisper and now we don't notice it at all. Moving our iTunes library and photos to the cloud took a while over LAN (which is to be expected), but now they are available from all our devices via the My Cloud and WDPhotos apps. It has plenty of room on it to allow us to scan our old negatives and photos and have somewhere safe and accessible to store and browse through them at our leisure.I would thoroughly recommend this version of the WD MyCloud series over the previous incarnations. The improved processor and RAM makes the PR2100 great for streaming HD movies so we can watch them on up to four devices in HD simultaneously. The fact that it runs off 2x6Tb Red drives in Raid 1 provides peace of mind that should one drive develop a fault we are safe in the knowledge that our data is still safe and only need to replace the faulty drive and rebuild the Raid.

I bought the My Cloud Pro 4100 on Prime day; as my home storage requirements had reached breaking point. I have been using a Netgear 4 disk NAS alongside a Drobo 5n on my home network; and had 6 different pocket disks that I had accumulated on my travels over the yaers. All in I had 10 years of personal photos; video and my iTunes downloads etc.Those two NAS devices were using random disks to make up the array; and between them they were full. Looking at the prices of disks it worked out cost competitive - the disks in the unit are WD NAS Red drives and amazon retail them for over 200 pounds each at the time I ordered the unit. So I ordered the MyCloud Pro.Arrived in a nice box; with clear instructions - which boil down to plug in network cable (included) and plug in power cable; then in a browser go to the devices name. Immediately I hit an issue; the WD Software just doesnt get on with Safari - the logon screen just spins and comes back saying its timed out. It works just fine with chrome though.Besides the safari problems the MyCloud software is defiantly lacking compared to Netgear's. The interface is easy to follow; and the settings gives you some great options. It is easy to create users and shares with permissions. There is an "App Store" to allow you to extend the systems features and it covers the basics - iTunes and DLNA which let you use the device as a stand alone media server for most situations. For off site backup to the cloud it offers an interface to Amazon S3 storage which is an affordable option for securely moving your data offsite.My Netgear NAS offers more app options (and a virus scanner); and the interface lets you explore the storage in the interface - which is great for deleting and moving things about without having to copy them over the network - which would have sped my migration from USB drives to the NAS had it been possible to move files in the UI from external to internal storage. . For a pro device I was surprised there was a database available in the App Store.For saving power there is a nice interface for changing the times its running - though it does make you do it day by day - its easy to get it to power down when you are at work and save some energy.Since setting it up I have spent the last month slowly moving 15Tb of data from my old storage over to the new one; and finally turned off my old storage this week (And I have a drawer of now empty pocket drives too.) Lightroom is figuring out my photo storage on a pc and look like it will be for some time. Opening files from it across my wired and wireless networks quickly load; and copying some iTunes content back to my laptop when taking it away from the weekend took minutes per Gb which was enough performance for what I want of it. Having 32Tb of storage setup as Raid 5 gives me good protection for my data when inevitably a disk fails; though its at the expense of storage - there is 23Tb of usable space - and I have used more than half already. Should a disk fail its easy to remove and replace them and there are clear indicator lights that will let you know there is an issue.The myCloud device itself is on a shelf gently humming as the fans ramp up on warm days. The DLNA playback has worked just fine with my TV; though using VLC to just connect to it as a disk is working nicely too.Getting a device with disks was a better choice for me than using spare / old disks as I have a clean start. It also worked out cheaper than buying the disks at the time I bought it. It should give me a couple of years to before its full at which point hopefully my home internet will have got beyond ADSL and opened up the chance to use online storage for all my needs.

Relatively easy to setup, although a little temperamental. A little perseverance got me there. Then I wanted to transfer quite a lot of files onto my new NAS drive from some old drives. I plugged in a USB 3.0 drive docking station and the PR4100 said the file system was unsupported, even though the docking station is fine when plugged into my Windows PC. The PR4100 claims to support FAT32, NTFS and a number of other formats so it should have been OK. A little research showed that this is a very common issue with the WD NAS drives. A Google search suggested a number of potential solutions, none of which worked, so I then resorted to a direct network connection between desktop PC and NAS drive. I managed to get the two to connect directly and I can copy files using Explorer. The problem is that the transfer rates are very low (30-40 MB/sec). My copy will take a whole weekend and I'm worried there may be copy errors. There doesn't seem to be an efficient way to get large amounts of data onto the device and technical help seems to be completely unavailable - there is a WD Community but my requests for help fall on deaf ears. If I had the choice again I'd go for a different device. Completely unsatisfied.Later comments: After leaving a copy of 700 GB for several hours it failed half way through with "insufficient memory". My desktop computer has 32GB so perhaps it is the PR4100. This device is a complete waste. I will seek to return it.
