Overall Review: I purchased this HDD in March 2021 along with an WD Ultrastar 18TB. In my Raid boxes a Drobo and Synoloy I have started making a point of trying to by different brand / models HDD's as I add storage just in case a defect in one line will not destroy my entire storage array. I have found the Pro series to be slightly noisier than the Plus / original regular RED's and a bit quieter than the Ultrastars. Heat is kind of similar based one feeling the front of the HDD while is mounted in its RAID enclosure. The first thing I did after this hard drive arrived was check CrystalDiskInfo to check the drives specs and make sure it was all good. It had a power on count of 1 (since I powered it on) and everything else was perfect and new. Hard drive Speed Compare: All testing was done with an external enclosure using CrystalDiskMark and a direct file copy (about 4GB) to the disk from an internal SSD.WD Red Pro 18TB: Seq Read 267 MB/s, Seq Write 266 MB/s, Copy 260 MB/sWD Ultrastar HC550 18TB: Seq Read 269 MB/s, Seq Write 268 MB/s, Copy 274 MB/sWD Red Plus 10TB WD101EFAX: Seq Read 218 MB/s, Seq Write 219 MB/s, Copy 80 MB/sWD Ultrastar HC510 10TB: Seq Read: 259 MB/s, Seq Write 263 MB/s, Copy 250 MB/sWD Red 10TB WD100EFRX: Seq Read: 200 MB/s, Seq Write 116 MB/s, Copy 186 MB/sSpeed comparison for reference. This is just a small selection of my hard drives that I have owned and have tested.I think I will be very happy with this expansive HDD.

Pros: Great looking design. Small form factor Hard to find a pre-built system with everything this has for under $700 low power usage and pretty good overall performance. silent operations though the BR drive does make high pitch sounds sometimes....?

Cons: First one died after 3 days of use. had just finished installing windows and all the updates, moved it to its final location and nothing. took 2 weeks between mailing to get new one back from newegg. I wish I had just built my own HTPC. Currently on the second one and so far so good. Its going on a week now and still working. I did some Lego Star Wars gaming on it as a stress test and ran avatar BR movie. I think I have noticed my blue tooth devices specifically mouse does not seem to like this thing. It has a large lag half the time between when I move it and when the courser moves. I dont have this problem on my 2 other PC's. This makes it feel under powered even if its my 2nd most powerful computer.

Overall Review: Ok listen up save your money. If I were to do it again I would build my self an APU unit. get a case you like get the A10, 8GB ram, SSD, and a BR drive and it costs around the same price for more performance. Thats what I with I had done. True it uses more power and wont be as small but it should be more reliable. When this thing works it good but Quality control dropped the ball with this device. At my time of purchase I had just bought an HDTV and wanted a fast easy solution for an HTPC. Do it properly and build your own. go APU if you want gaming capability otherwise intels work great. the HD4000 works find of old games and semi new titles. I read many review while I was waiting for the replacement.... '-_- Good luck hope this helps you.

Pros: Legit copy of windows.

Cons: cost $$$

Overall Review: works like its supposed to.

Pros: 8 bays. Easy setup, check sum for data reliability, data scrubbing, and have any side hdd combined into a single Raid. dual disk redundancy.

Cons: expensive considering model year.

Overall Review: Great NAS. My 2nd synology. also had DS1819+. Got tired of waiting for 2023/24 model go bought this. using it to backup the 1819+. Also have the 10gig expansion card. Transfer speeds around 250MB/s, sometime 300MB/s. No SSD for acceleration. using hyperbackup as the backup solution. Runs fairly quiet. Fans are easy to swap in the future. Can set up power on and off schedule and works with UPS in case of power failure.

Pros: Great performance Good price per gig Reliability from trusted brand

Cons: a little noisy and expensive

I have this installed in a Synology NAS. Its running great.

Pros: Very large capacity Fairly Quiet operation for a HDD Fast for a HDD Great in synology NAS

Cons: expensive. Makes a slight tick noise when idle. Not bad ticking like its failing like a thinking tick HDD's make when working expect it should be doing anything. Not terrible usually dont notice.

I bought a WD 2.5" Blue hard drive from this seller. On the website it is listed as NEW, with warranty. In actuality this seller only sells this product as an OEM. OEM's do not have a warranty. After a number of emails back an forth the Craving Savings agreed to give me a discount for the inconvenience. I'm giving them 4 stars because I found the discount acceptable. As a note to this seller they really should say if the product is OEM up front.

Item was accurate. Shipping was normal / quick. Good Seller.
