TOSHIBAN300 PRO 14TB Large-Sized Business NAS (up to 24 bays) 3.5-Inch Internal Hard Drive - Up to 300 TB/year Workload Rate CMR SATA 6 GB/s 7200 RPM 512 MB Cache - HDWG51EXZSTB

This is the standard drive I use in most of my NAS devices. We have a dozen users who use files on the NAS 16 hours a day, 7 days a week and these drives hold up well. In the past five years, out of 24 drives, I have only had 1 fail. I have tried other brands in the past with slightly worse stats. Note: Toshiba manufactures many other brands as well.

I had been running a plex server with up to 18TB or so in content. This was split over 3 external usb drives (8TB, 8TB, and 6TB) but I have been running into issues with what appeared to be the drives going to sleep. However, it was the 8TB drives just simply dying, looking at the smart stats they are erroring billions of times. So, I decided to stop buying drives from Costco and just slap in some enterprise drives to my dedicated Plex machine. I paid slightly more than the lowest price for these because I wanted them to be sold by amazon. I have bought other IT items from sellers on Amazon but sometimes you get refurbished gear/drives with it being disclosed.The price per TB is higher than normal, a good price for drives in this size is around $14 per TB. So far these drives are 100% performant regularly hitting 150MBs + and have 0 errors on them. They are rated for way higher usage that I will ever use. As I migrate data and fill up these drives I will buy another as needed.100% recommended.

Great disc, my only complaint is that they are a little noisy, if you are going to have the discs in room or private office, in a data center you wont hear them.

Bought two of these HDD's for a NAS and then the NAS was delayed. When I finally got to install one worked and one just made a horrible clicking noise. Both drives were not opened until install time and prior to that sat in a cabinet. Tried to exchange but was just outside the return window. Lesson learned. Do not purchase HDD's from Amazon until you have the device they are to be installed in so you can test and return if required.

I read some slander review about ESD ruining the drive, failure was due to the user.First off let me be frank, its a hard drive...these things happen when they're shipped around, especially by (lets face it) people who really don't know anything about sensitive electronics and generally don't care.I have a 2ft x 2ft x 1ft monster of a rig with 7 drives (6 Sata, 1 NVMe) running on a PCIe power swap controller, a 3090 24GB, Capellix Elite 360mm rad etc etc....you get the idea.I ALSO HAVE an 8TB N300 NAS running constantly in one of my bays as a tranfer/backup drive...I have for over 2 years now (and I also had to have that replaced once first), I deleted and recovered the entire partition at one point picking the wrong one by means of a typo and I've been programming and repairing PCs for almost 30yrs now.With that all out of the way, we can safely say I know how to handle electronics...and I've gotten 2 DOA Toshiba drives from 3rd party sellers off Amazon in about 2 months.UPDATE:I can't speak for the first drive, but the second drive, the Toshiba NAS Pro 4TB this review is for turned out to be working fine.Seems it was my PCI Drive Power Swap mentioned above had partially melted glue that held the Sata connector on the board.Ironically this only happeed with NEW Toshiba drives (I.E. the "Pro" series), I had no issue on the same cables with my older 8TB NAS drive.I'm "guessing" it has to do with a new design, likely that saved the drive from any long term damage by powering off, my Toshiba P300 I replaced with this was not so lucky heh.I'm leaving the rest of the review so people know what to look for that may tell them its a power failure...as well as how much hassle it was due to a 3rd party seller, although they followed up with me to the end, no form of resolution was follored through, although they agreed to one.END UPDATEIts gotten so bad I absolutely refuse to return it without them shipping another out so I can clone my data over first, which I'm still waiting for a response now.It works, it doesn't, it boots and stays running for an hour...then won't boot 4 times in a row.I switch both connection to others that always work perfectly fine, its 50/50 I can even load the drive. I've tried setting it to hotswap in my BIOS, I've tried connecting it by itself with nothing else which of course is when it decides to work for a short time, then poof, Windows BSOD and won't boot again.It has a lower voltage needed than my N300 8TB drive and I've swapped them and the sata/power cables running them with no luck.I have 5 other Toshiba drives--this was actually a larger replacement for a P300 that finally went after almost 6 years. I am loyal to Toshiba, the Warranty and replacement OR refund if no similar product can be shipped is incredible, but I have the absolute worst luck buying PC parts off Amazon.I had high hopes when this arrived in a Newegg box, but alas...that just made it harder to reach the seller and get some sort of resolution.I recommend Toshiba drives, truly, what I can't recommend is buying them from a 3rd party off Amazon, at least if you buy direct you know your covered...frankly I'm disappointed in the service I recieved when they couldn't reach the seller because of an incorrect phone number.Case closed, A to the Z, now refund me and send me one from Amazon at least...I can't say its the sellers fault it was damaged--Amazon needs to put some quality control in place or take a hand in any sensitive electronic because its just making them and Toshiba look bad at this point.I'm giving it four stars because I have updated the reason of failure and knocking off a star for the lack of service resoution and I absolutely stand behind Toshibas products.I would buy the drive elsewhere or make sure you have the time to thoroughly test it before swapping your data over like I did and scrapping your old one.ESD, thats actually almost comical to be honest...if you can manage to destroy a drive with unintentionally ESD, I would actually pay to see the internals after the fact lol.If you believe that you shouldn't be buying a Hard Drive without a sales associate next to you...maybe not even then.
