The A/V drives ignore errors, the normal drives will do an error recovery to attempt to get back any data from the platter.
When recording video (security cameras etc) you want an A/V drive that will just record whatever you throw at it, and keep going even if it misses a byte or two. An error in a couple of bytes just causes a minor blip in the video stream, but the rest won't stop. On a normal drive it could go into an error recovery mode and stop recording for 10-30 seconds - and this is much worse for security.
However if you store documents, a single byte error could corrupt megabytes or even gigabytes of important data.
Which you choose depends on your purpose... 这里的2L:
