    From experience, a massive amount. It's not the throughput that's most noticeable, after all. I have SSDs in several early C2D laptops with the ICH7 southbridge, where only SATA 1 was ever enabled. They still speed up considerably with an SSD, especially where the BIOS will allow AHCI mode.

    Yes the SATA connection speed is irrelevant in real world SSD usage.

    Its all about the 0.1 second response time. Those transfer bandwidth graphs you see on benchmark tests are totally pointless metric in a normal computer use situation.

    What @3s-gtech said!

    We have some very old laptops that have an SSD inside a PATA to SATA adapter (so ~100MB/s max) and there is still a noticeable difference in terms of speed compared to a HDD. Most I/O is random reads/writes which is where SSDs excel.

    SSD put into a 2010 or 2011 MacBook Pro. Boot up time was 1:10.......now the boot up time is 10 seconds. Flat. After logging in, everything (Dropbox and other programs) load in about 2 seconds.

    Cost? 256gigs for $100. Well worth it.

    That's good - although when I had a SATA 3 SSD ( 6gbs ) and was using it on a SATA 2 connection, I was only getting about 270mbps read / write ( give or take a bit ) and wasn't getting as much IOPS as I could have done had it been a SATA 3 Port / chipset that I was using it with.

    Think it was advertised about 550 mbps read / write roughly, would love to get another SSD such as the 840 evo or pro and stick that in my 2011 mac mini which has SATA 3, I bet that would make it fly !!

    I originally had an OWC 240 Gb Mercury Extreme Pro 6G similar to this ( http://www.amazon.co.uk/OWC-OWCSSDMX...productDetails )

    Which I believe was only a 60k IOPS drive and was using it in a 2008 Mac Pro as my boot drive

    The transfer speed (benchmark of copying a large 4gb file from SSD to SSD usually) is a pointless metric in the real world. Ask yourself how many times that would happen in day to day usage.

    Its all about the random access file response time really, which is the same no matter what interface you use.

    I was using handbrake to convert MKV 1080P HD video to MP4 etc so reading / transcoding from original 10gb or more file size to an MP4 that I could use on my phone so I was effectivly copying from SSD to SSD

    It mattered to me ............... :P

    Haven't had an SSD for a long time now - which is a shame as it did make a big difference between a mechanical HDD and an SSD in terms of speed and responsiveness
