Dear Apple,

Please give us TRIM.

Hugs & kisses.

Ok guys, here I go again. I'm going to try ATA-Secure erase my SSD again. This time using the the hot swap method to unfreeze the drive. This could go well and my drive could be up to full speed again or it could brick it and I'll be ordering another vertex 2 from OCUK tomorrow. Wish me luck...!
 
Well it worked. I had to hot plug it though to get the drive to an unfrozen state. I'm gonna post a guide when I get some time.

That'd be awesome, been trying to do mine but can't seem to get it to work.

Well you have a similar set up to me, so a quick guide for you would be this;

  1. Burn Ubuntu 10.10 32bit edition.
  2. Back up all your data.
  3. Open the back of your mac and removed the ssd and pull the cable to the side.
  4. Place the back to where it should be, without the screws, so that when your mac is upright the cable is sticking out to the side for when you need to hot plug the drive.
  5. Put the Ubutuntu disc in your drive and turn on the Mac, holding 'alt'.
  6. Press enter at the 'Windows' Disc icon and soon as the screen goes blank plug in your SSD.
  7. The rest of the guide can be found at https://ata.wiki.kernel.org/index.php/ATA_Secure_Erase
  8. Your drive should be unfrozen already.

The only part I got stuck with was after setting a password to my drive, the SSD would stop responding to HDParm commands. Simply unplugging it and plugging it back in solved this.

Also, if you have no other external drives connected, the SSD should be 'sda'. ;)

Nice one, cheers.
 
For anyone worried about performance dropping off, here's the stats from mine from when it was new compared to now.

I'm running with nearly two weeks uptime and I have a dock full of running applications.

There's an image in this thread that shows that after ten days the performance had dropped to 315 so only to have dropped another 15 marks in five months is good. I've not noticed any slowdown (duh, it's bloody quick) and I've not run any maintenance on the SSD at all.

It was a damn good investment.

Tried your way on my MBP booting into Ubuntu but when I run the 'hdparm -I /dev/sda' I get a return of 'permission denied'.

Have you removed all other drives? Are you using the internal DVD drive or have you got an external drive? It's possible that your SSD isn't SDA, it could be named something else. There is a unix command that will list your drives but I can't remember what it is, you'll have to google it.

Seems pretty slow compared to you guys, this is a fresh Snow Install on 1.28 Vertex 2E drive.

Maybe I'm limited by the SATA controller?
 
Can you post up what you get on system profiler? This bit:

it could be the unit is write fatigued and needs an erase.
