None is important for a HDD, for two different reasons:
1.They aren't sufficiently fast as to saturate a 3Gbps link, so 6Gbps is pointless/marketing
2.Cache has been proven not to bring much performance benefit. At some point it did, when going from 8MB to 16MB, but 16MB seems to be enough considering how fast HDDs are in general

My tale is that as long as your current HDD works fine you should keep it. If you can change for free you can do that, but if you have to play any price difference, it's not worth it.

You do realize that a green drive is designed for storage, right? It's eco-friendly, hence "green". They are designed to use almost no power at the cost of speeds. They aren't fast drives (although they are fast when compared to other storage drives).

If you want a gaming drive get an SSD, or a black.

P.S. 3Gb/s or 6Gb/s is not going to matter on ANY mechanical hard drive, especially one designed for storage. Even most SSDs can't take advantage of 6gb/s. Don't worry about that. 32MB vs 64MB cache is also not going to have any noticable benefits.

I believe that these drives have a maximum sustained transfer rate of approx. 110-120 MB/s.
That isn't fast enough to saturate a 150MB/s (3gb/s) SATA link, let alone the newer 300MB/s (6gb/s) SATA ports. So you are good with your 64MB cache drive.
A 7200 RPM drive however will serve you better as a primary drive.

I own a WD10EARS and I do not recommend it as a gaming drive. It goes to sleep in a matter of seconds and takes a few seconds to wake up. It's great for multimedia storage but putting games on it is a terrible idea.

A Seagate 7200 RPM 8mb cache drive is faster than a WD Green 5400 RPM32 mb cache drive.
Cache made a huge difference between 2mb to 8mb, minimal between 8 and 16, and for most anything above 16 is not noticeable (this all being compared on a same speed drive, RPM's make more of a difference).

Actually, 150mb/s is SATAI, 300mb/s is SATAII, 600mb/s is SATAIII
