SSD Speed and sata cables?
Does an ssd lose speed when it is getting full? Also should all the same ssd's perform relatively the same with no big difference in speed? One last thing here are there 2 different kinds of sata cables or do all sata cables run at sata 3 speeds?

An SSD should not slow down as it fills up the way a HDD might, but it may over time slow a bit, but probably nothing you would notice. I couch this in "probably" & "should" terms because the jury seems to be still out on some of these issues. SSDs have only been used extensively for a few years, making long-term knowledge a future thing, and the technology keeps improving as well. Also, since you are not supposed to defrag an SSD you don't need to leave that last 15-20% unused for that purpose.
Your other question - "cables" - it's not really the cables per se but the mobo's ability to transfer to the drive. Many have now made the move to (3rd generation) SATA III, a.k.a. 6Gbps (Gigabits - not bytes - per second). However, some SATA II (2nd generation SATA - a.k.a. 3Gbps) boards and SATA II SSDs are still being sold, so for the faster performance look for SATA III (not quite twice as fast as II). See Sandisk's explanation here for more (like throughput):
Note that, as always, speeds quoted are "up to", and a SATA III SSD connected to a SATA II mobo (and vice-versa) will only get SATA II speeds (slowest link in the chain idea)... Oh, and different brands and models of SSD do have different specs, but you probably wouldn't notice these differences either unless you ran benchmarking tests.

No it doesn't.
