An AV drive is designed to IGNORE data errors, whereas a 'normal' hard drive will attempt to re-read/re-write problem sectors for a set period (up to 15 seconds, depending on the drive) until the internal checksums shows the data is consistent. For a desktop drive this is what you what - it makes sure the drive stores and recalls the correct information. However as the drive is unresponsive for the retry period, it could cause a blip in the video if used to record an AV stream. As a result AV drives ignore any errors and just keep going - a small artifact in a video is preferable to a break in the stream. Such an error could have a huge impact to system stability if it occurs in an OS file though, or it could corrupt a photo or other document and render it useless.
Now you will probably never see these issues, at least while the drive is new. But they are not designed for use in desktop (or 'normal' RAID) systems as they can corrupt data. This is the reason why manufacturers make enterprise disks and video disks - the drive may be the same, but the error-handling firmware is different.

It will be fine, it is designed to have data constantly written so it should last a long time in a PC

Good price but it's an AV drive. Not designed for your typical desktop storage although it may well be fine.

I don't get why they have a version specifically for surveillance, what would be the downsides in using this as a NAS drive?

Useful in a server (or NAS) setup - cracking price (if it actually ships).

that's not really what makes it an AV drive.
