Toshiba N300 PRO 18TB 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 - HDWG51JXZSTB

Bought these when the price dropped as a lower cost option to the same size WD Red Pro drives.. They have proven to be reliable - so far, with all units surviving 72 hours burn in and several more days of moving terabytes of data too/from these drives. I will buy more when needed.

Considering the noise it makes, it sounds like I installed a popcorn maker in my living room.

My new second choice when I can’t the WD Red Pro drives I need. Haven’t used these before, but so far it has survived a 72 hr read/write burn in test, and the read/write performance is similar to the WD Red Pro of same size.

Would LOVE to know what the deal is with these drive via AMZN! OUT OF WARRANTY even before I open the box! I checked the SN on the Toshiba site... the drives are listed as OUT OF WARRANTY! I decided to go back and check my last 2 Toshiba N300 Pro 8TB drives as well and all 3 checked out the same. All drives when purchased were listed as sold by and shipped from Amazon. I checked Toshiba and it's a real SN and matching PN, which means it at least is NOT a counterfeit drive. I checked CrystalDiskInfo and they all had zero run time and zero power on counts, so at least they are NOT used. They are fast and perform really well, just concerned about a brand new, out of warranty drive.

I purchased 6 of these N300 Pro 18TB drives two years ago. I use them in a home NAS that occasionally plays movies. Last year, one hard drive died. I purchased another exact drive to replace it, and was unable to warranty the defective one. Now a second drive is showing S.M.A.R.T. errors and needs to be replaced. Again, I am faced with Toshiba telling me that my hard drive was sold to a system manufacturer with a unique system warranty, and that I need to return the drive to the system manufacturer! I bought it here on Amazon as a brand new, retail hard drive! After many decades of great memories, it now looks like I am done with Toshiba hard drives. A failure rate of 28.5% is absolutely unacceptable. Not only that, but I am going to be out another $350 to replace ANOTHER drive after only 8 months of light use! (The first one died right at 12 months of very light use!) Toshiba, please feel free to message me here and let me know that you'll work with me to get these drives properly warrantied.
