I just got this yesterday after a long weekend wait and let me tell you this thing rocks. And it rocks fast :). I am going to give you a review on a perspective of real world use and not on benchmark with all the numbers, not yet anyways.
I bought this for my MacBook Pro unibody and it is the best upgrade I have ever done. The speed is just simply mind boggling. I was shocked on how fast everything is. I am not talking about user wishful thinking, bias opinion of the speed gain, I am talking about screaming fast, jaw dropping speed. To give you some ideas on how fast this thing boots up, with the original stock drive, I got out a stop watch and timed it (not very scientific here but it'll do) and it took 1 minutes and 46 secs to cold boot the MacBook Pro into the desktop. With this new SSD, it took 22 seconds.
Applications loading is extremely fast as well. I mean, as soon as you hit the icon, the app is already fully loaded. I have a 8000 songs iTunes library plus about 40+ movies and 10 TV shows and iTunes loaded with lighting speed. It used to take at least a full minute to fully load iTunes, now it takes, literally 1 to 2 seconds (yes you read correct 1 to 2 secs to fully load iTunes).
I also have Photo collections with several thousands pics and it took, are you ready? It took 2.2 seconds to load the entire library. How cool is that?
Safari and FireFox are both stunning in loading speed with about 8 tabs of web pages.
My machine was running fairly cool with the old drive but when watching movies, the machine gets warm or sometimes hot to touch. With this SSD, I watched a full length 2 hour movie and the bottom of the MB Pro is steel cold. The fan never kicked on the entire movie. In fact I have not heard the fan since yesterday. To be fair, the MB Pro is so efficient that I never had any problem with heat or hear the fan noise but with the SSD drive, it is just dead quite. Very strange to use a completely noiseless and steel cold to the touch notebook.
About the drive. I did extensive research and found that this is one of the very best right now, watch out Intel (I think Intel still is the King). Before you get turned off my the name Corsair, it is really a Samsung drive with Samsung RAM chips and controller. Samsung has its own version of 256GB SSD but they only sell to OEM and not regular folks like you and me.
Installation of the drive into MB Pro is very simple. Remove one screw that holds the drive and remove the 4 screws on the old drive (need special screw driver for these 4 screws). There is a video from OWC computing that shows exactly how to do it.
I first put the SSD drive into an external USB enclosure. Downloaded SuperDuper, a free program to clone my old existing drive to the new SSD. Installed the SSD into MB Pro and boot it up. The first time booting up with SSD took a lot longer than what I stated earlier. I believe the OS needs to do some configuration for it first. After another reboot, the speed was astonishing.
I know that this is not cheap and I hear you. But if you want the joy of the greatest upgrade ever in the history of upgrading, this drive is the drive to get. Also, DO NOT go cheap on SSD drives. You get what you paid for. All SSDs are not created equal. Go do some research before buying but if you want to listen to someone who already did the research, read anything and everything on SSDs for years, then run, don't walk and buy this awesome drive.
