Different Seagate HD Models - What's the Difference?

I'm somewhat confused, what is the actual difference between these three Seagate Hard Drive models? They're all internal 160 GB SATA 3.0.

The first one appears to have perpendicular recording, and the third one says something about video and is about $8 more expensive, but other than that I can't see what's different about these three drives.

Would I notice a difference if I bought one over the other? I'm currently using a mobo with the SATA150 interface, but sometime in the next 6 months will probably upgrade to one with the SATA 3.0 interface.

    The first one is the latest seagate drive .. the .10

    The second one is the 'older' drive.. the .9 ... i have no idea of specific differences.. only that it is an older revision.

    The last drive is something about video, i have no idea because video storage vs other storage seems like no difference to me. The only difference i see is that the last drive has a seek time of 17ms vs 11 for the others.

    Go with the first one.

    Be careful upgrading drive types. I think there are no interfaces that will use the 'Full' speed of the 3.0 interface , but the real advantages come from using the drive in AHCI mode .. which gives hot swap capability, better transfer efficiency, etc...

    I needed to reinstall my OS after going from IDE mode vs AHCI mode later on.. And make sure you pull the jumper...

    I think the difference between the .9 and .10 is that .10 is using the new perpendicular recording which allows higher storage density than longitudinal recording. This means more data per platter which means fewer platters which means (theoretically) better performance and fewer moving parts which means (theoretically again) longer lifespan. I'm pretty sure the .9 revision didn't use perpendicular recording, anyway.

    That third one you don't want. The SV series is somehow specifically designed for use in video surveilance systems (the only specific thing I can find is the ability to write multiple data streams to the disk at once, which I would think would be a benefit for any usage) and whatever its intended use, it's fucking slow.
