      In the past ten years, I have had very good luck with Toshiba drives. I've had this one in service for a couple of months now and my only complaint is that it is really loud. It is so loud when seeking that it reminds me of Maxtor drives from the 1990s. Performance is good and if it is as reliable as my former Toshiba drives have been then I will be happy with it.

      Hard drive itself is very good. However it was NOT packaged properly for shipping. They took display box and stuck a mailing sticker on it. NO padding NOT in mailing box. Pack hard drives better. Again the 3.5" 4tb 256mb cache is very nice. Lots of storage. Great as an external drive under Linux formatted as ext4 for running virtual machines.

      Drive works great, service was sub-par when I thought it didn't.

      Brief content visible, double tap to read full content.
      Full content visible, double tap to read brief content.

      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 UPDATE

      Its 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.

      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.

      Put one drive into Synology NAS and it started having I/O errors. Tested it on Windows desktop using SEATOOLS, Toshiba Drive Tools, Aomei partition - crashed every time, when I finally got a test to start the first 24 sectors reported bad before it crashed again. Put in the second HDD from Toshiba and it worked fine.....Returned and purchased a more expensive Seagate Iron Wolf Pro....
