Is SATA II cable different from SATA cable?

[WDS]

Is there any such thing as a SATA II cable? I just bought an Intel SATA II
RAID controller and it doesn't come with cables. A quick trip to Fry's
revealed they don't carry anything called a SATA II cable.

Is there a danger in using the SATA cables I already have?

The only difference I noticed is a clip, however SATA II incorporates,
Stagered Spin Up, support for 24 foot SATA cables, Native Command Queuing,
Click Connect which as I stated earlier is a clip that stops the cables from
disconnecting so easy. There are a few more that are out there and some
drives use certain ones but not others.
