'optimized for CCTV' - does some one want to give me an explanation of what that can mean other than marketing BS ? - the disk conforms to SATA standards and I can format block size however I would choose ... so how is it optimized ??

I think it means that when a bit of the disk goes physically bad, it won't spend too long trying to correct the error. That way you achieve continuous realtime recording unlike on a conventional disk.

really ?? if there is an error it is more inclined to ignore it ? - is that a good thing ? ....isnt it better just to make disks that don't fail ? are they really making disks for such as small market (as most others want failure redundancy)... I still smell marketing BS to be honest.

Yep - similar situation with the WD Reds - they are all very similar but have different Time Limited Error Recovery (TLER) settings. "TLER prevents a disk that has a read or write error from going into a deep error recovery mode to attempt to read/write to a sector it couldn't previously read/write." - this stops it working properly for a bit - so is bad for RAID setups or CCTV type work. They will also have different settings for the sleep type settings (time they wait to park the drive heads) - although this can be altered.

Apparently if you put a regular HDD in a CCTV box that has several cameras and you'll find it will die fairly quickly. Usually within 12 months.

Paul Merton is correct in his explanation.

If you want to go against the 'marketing bs' I'd certainly be interested to hear your results and experiences further down the line
