Pros
Cons
A good disk, 6 TB is enough for me and everything is fine with games. I use it a little and have nothing to say but so far so good. Everything is fine, the disk works great. It vibrates, you can get used to it as it’s not that strong  Renal Arifullin: use Toshiba HDWT140UZSVA few months |
It’s just the second month of its operation, it records all this time without stopping, both on weekdays and on weekends, it’s ideal for storing because it records video from a bunch of sources at the same time, you can immediately view the recorded video - no lags, missing files or other problems. The head rotates quietly, the heating level is not high even without rest. Response times, read and write speeds are mixed, random and sequential are fine. It is specifically designed for working with video, because there are nuances for other tasks, well, with tasks where only linear access to data is also suitable. No, the disc is good. Smirnos: use Toshiba HDWT360UZSVA few months |
The opinion is still raw. because the disc was purchased only 2 weeks ago, we read everything we could find about it, and decided that it would be suitable. We expect stable and long-term operation from it, while it has been working non-stop for these 2 weeks, the speeds are high, both reading and writing, both random and multi-threaded, it is designed for recording streaming video. We have 24 cameras installed in the building, and the video from them is uploaded to this hard drive, the old one died 3 years later, in short, after the warranty expired immediately, now we are trying a new drive and a new brand, it has better parameters and a larger volume, and supports the work with more cameras, 12 more cameras will be added soon. Stable. It heats up weakly, there is vibration suppression. No SeSenko: use Toshiba HDWT31AUZSVA less than month |
