Good reliability HDD
Works well. Toshiba HDDs usually last longer; however, they can produce more noise. With Hikvision NVR and DVR, they have a feature built into the software that can monitor temperatures on Seagate HDDs. However, the operating system still reads the HDD temperature of all hard drives and can alert you if they overheat. This could be one reason people go for Seagate, but even after two years, it's still fine. If there was a fault, it would usually die within 12 months.

Works OK for 6 months in NVR
Using it as storage for NVR - works alright, no noticeable noise, no issues.

Hard drive
Easily installed, good storage at 6TB for what I needed, no issue with read/write speed. Ive used Toshiba before and very reliable, quiet and good value for money compared to other surveillance hard drives at this capacity.

Does the job. A bit noisy
Use this with a Reolink NVR and 6TB is enough for about 30 days with 4 x 4k cameras. IThe Toshiba HDD is a bit cheaper than the equivalent WD Purple or Seagate HDDs. Not actually a problem but I don't like mechanical noise because it means more wear.On this particular NVR after formatting there is 5508GB available storage.Cost wise: the 4TB HDD works out a bit cheaper per terrabyte than the 6TB HDD.

Cheap and cheerful
Well packaged and exactly as described. It's almost silent, was plug and play and feels strong and of high quality. Despite the low cost, this works perfectly and I wouldn't hesitate to buy this again.

Good value Ironwolf alternative.
Has better specs than the equivalent Seagate Ironwolf for a fraction of the price. Slightly noisier than my outgoing 3TB but quite a bit faster. Given the 1 million hour MTBF figures I may never have to replace this HDD ever again, nor my children nor grandchildren. Excellent value. Install and forget storage solution. Quality.

Good service but the product failed.
Sorry to say I had to return the hard drive, it failed, my Zpool emailed me a warning about (spin up time)Tried it in another zpool but after two days another fail.Got another disk from another company, so far so good.Thanks for asking. Geoff.

Seems to work well up to now
I am in accredited CCTV installer. I was sick and tired of replacing Faulty Seagate rubbish hard drives that seem to fail within two years. Decided to give Toshiba a try. Fingers crossed 🤞
