Pros: -Fast
-Western Digital
-Good Price to Storage ratio
-Quiet

Cons: This may not really count but the software it comes with I don't really like. With any WD external drive the software always seems kinda lame. There are multiple pieces of software that come with the drive and the basic WD utility for managing the drive for like picking raid configuration, sleep timer, drive check etc... isn't that bad but could look cooler, very simple functionality with no extra junk which I like. I'm more referring to the backup software that it comes with, not that I was going to use it as a back up but could have been a lot nicer backup software, it integrates with dropbox, not sure why, and apparently there's a paid version, the version that comes with the drive is the free version and there's like a spot in the program that says like upgrade to pro or something like that and I have all programs that do that.

Other Thoughts: I would definitely recommend this product. I use it mainly for storing media for a plex server and I picked it over a NAS system because I figured it would be faster and I think I was right, I get 288MByte/sec read and 280MByte/sec write in raid 0 its default setup which is awesome using the USB 3.0 cable it came with. A weird issue I have with it which is probably just a setting on my laptop is that every time I reboot my laptop which the drive is connected to I have to change the USB 3.0 port the drive is connected to. When the computer boots back up after reboot the drive doesn't show, if I unplug it and plug it back in my PC makes a noise like it connected but there's no trace of it not even a missing driver but when I change ports works no problem. 7.27TB is what my PC actually sees in usable storage for those wondering what the formatted capacity actually is. It's very quiet. It comes with 3 pieces of software I recommend only installing the WD Utilities one and maybe the drive security one if you need something like that, the backup software I didn't really like, not that I was using it as a backup anyway, didn't really use the security program but it seemed straight forward, and the WD utilities program was very straight forward and serves its purpose. It does vibrate a little bit which is expected with mechanical drives, I put it on a mouse pad and it solved it. Again really quiet either way. I really like this drive and $350 for two 4TB drives and a dual bay raid enclosure really isn't that bad considering to buy a 4TB WD red drive right now would cost $150 each thats $300 for the drives and $50 for the enclosure.

Pros: Works excellent - fast

Cons: I have installed two of these and own one. In 2 out of 3, we kept having USB 3.0 issues. We kept working on ASMedia drivers pulling our hair out. Turned out - the USB 3.0 cables shipped with these devices are defective. Once we replaced the cables with good quality 3.0 cables - ZERO issues since! Hope this helps others dealing with this nightmare.

Pros: Was very easy to configure

Cons: Expected but total size was very close to 7.2TB

Pros: This is going to replace another storage system I have.

Easy to set up. About as plug and play as you get. Extra software was easy to install.
Using Windows 7 and usb 3.0 this thing flies, backing up an iso of Ubuntu (.9 gig or so) in 10 seconds and backing up my c drive was much faster than my current nat.

Cons: This isn't really network attached storage, it is more computer attached storage. While it should be possible to link it to a Network these instructions aren't included. In fact the instructions are a couple of pictures. Then again, they really aren't needed for computer attached storage

Pros: Lot's of space for movies, music, pictures, game backups, etc. Dual 8TB drives is great. Seamless RAID, drives are easy to access and replace if ever needed.

Being able to centralize media in a single l drive location is perfect especially if you need to take it and run quickly. (fire or traveling, etc)

Gray coloring blends into my media setup unlike my previous 2TB World Book that was white.

Very fast transfer speeds over USB 3.0. I've seen peak transfers around 280MB/s but I don't typically monitor it. Source drive has a lot to do with the transfer speed. SSD to USB are very fast.

Works with Dish Network, LG BluRay player, Windows 8.1, Windows 7.

Large 1080p movie files stream with additional traffic without issue.

Runs cool
Indicator light is dull unobtrusive white.

Cons: none to note, just not the most stylish of devices, it's looks will not impress your family.

Other Thoughts: May have issues with 8TB with some routers. TP-Link AC 1750 router would not recognize this drive as a media device. If using this over network be sure to check your router's USB connection (3.0) and max hard dive specs.

Not sue why other comment has idling issues. Probably some software accessing the drive constantly. Don't see this issue while hooked up to a large network of computers and other media devices.

comes preformatted to NTFS.

Pros: I bought this drive specifically to be used in RAID-0 for my video editing Media Drive.

I am using a PC running windows 7 with 4Ghz Core i7 6-core processor. 64GB RAM. 2x GTX 560 Ti Video Cards. ASROCK Extreme9 Motherboard.

Using Black Magic Disk Speed Test I am getting around 150MB/Sec WRITE and up to 250MB/sec READ. Not quite the advertised 290MB/Sec but there are other bottlenecks and not the fault of this drive.

Editing video has been a breeze. I am able to edit Apple ProRes 422 HQ footage easily.

Cons: My only issue I have had is the internal temperature of the drive. Just sitting idle (not transferring data or editing video from it) it seems to sit at about 47 Degree Celsius. During large file transfers it got up to 59 Degrees Celsius at one point. Both temps are very hot in my experience with hard drives.

I have heard from others than WD states this drive can withstand temps up to 60 Degree C...but even that is a little concerning. I am actually waiting on an official response from them as i write this. There is a fan in the unit that I hear only kicks on when the drive hits 60 Degrees. I haven't gotten it that hot for the fan to kick on so i cant coment on that.

Other Thoughts: Overall...great drive as long as those temps are within its operating temp range.
