I was surprised by the quality for this price.

Quote from Habra:

When choosing a drive, look at which segment the manufacturer positions it in. If you need a drive for a video surveillance system - choose purple, if you need a drive for a NAS - choose Red, if you need a drive for a home PC for home file storage - choose blue (the current blue series replaces green)

Also, when choosing, keep in mind that some series, in addition to other settings for drive modes, are subject to other warranty obligations.

Pros

I haven't been using it for a long time. I use it in a PC a la "file dump", I move heavy video files (4K) back and forth. The speed bump (thanks to the cache) is impressive against the background of old disks produced in the first half of the 2022s. As long as it works properly. Let's see how long it lasts.

Cons

NOT a drawback, but a comment: The Purple-series of the type is positioned for 24/7 video surveillance . Ie. something there in the mode of operation is configured for this. What exactly, whether it is necessary to do something, I still have no idea (I'm too lazy to figure it out yet). Sooner or later, you need to get to the topics of head parking, special programs, etc.
