Apparent incompatability or problem with new SSD

Hi all,

recently upgraded to 10.9 with few issues. Cloned my drive to external. Went about top upgrade my 5-year-old laptop:

MacBook Pro 5,4 (Mid2009) 4GB 250HDD --> Crucial M500 6G SSD + 8GB RAM.

This is a machine with a 3gbps SATA-2 contorller. Some reports of issues with 6G drives, but crucial swore up and down this worked fine in their lab.

INstalled drive. Updated firmware. Booted externally. formatted (HFS+ Journaled). Checked good.

Began clean install of 10.9. Took 4+ ours, including nearly 2 hours for last "one minute remaining". Somethign is very wrong.

Nevr would boto internally. Re-booted external (USB), copied fioles to SSD. Slow, and again, last 10% agonizingly slow. Eventually finsihed.

Tried duplicating those ifle sinternally SSD-SSD. Same or worse - started med-fast, took forever to complete.

Re-installing the OS will nto be helpful if the SSD wont perform.

Any thoughts, tests or swear words i may not have in my repetoir?

Well, the saga is over and the ending is happy. Thanks to all who contributed, especially clintonfrombirmingham who correctly guessed the problem and send me down the right track.

Yea, it was the cable. I bought a new cable, but to my surprise, the instructions provided were for a cable + sensor assembly. So i had to play with those teeny, tiny little wires nad connectors, always sure i was about to bugger the thing.

I didn't.

Cloned back, then installed over the clone, and its great. One thing i need to confirm is that a recovery partition was created. For some odd rason CCC did NOT create one (one of the reasons, aside from starging out clean, that i insatlled over the clone).

Write and read speeds, per black magic, are roughly 10x what they were ⚠; about 200 MB/s writes and 250 reads.

I do have trim enabled since crucila told me to, btu i also know you told me NOT to, so some experiementation will occur.

This is not acting like a 5 1/2 year old laptop.

Great. Good job. Remember to check in SystemInformation if the Trim command is still there after each OSX update....

Happy new year.
