Did you upgrade your MacBook Pro's HDD?

I have a MacBook aluminum. I use an OCZ Vertex 2 60GB as a system disk, and a 1TB 5400RPM Samsung HDD for my Data. I decided to use the OCZ because multiple technicians recommended them. For data, I chose the Samsung because it had the best price.

I have a MacBook Pro 15" Early 2011 Model with 8GB RAM and a 2.2GHz intel core i7 sandy bridge processor. It came with 4GB RAM, but i upgraded it to 8, and it came with a 750GB 7200Rpm HDD. I recently upgraded to OCZ Vertex 4 512GB. I chose the OCZ Vertex 4 because it seemed to be one of the fastest SSD's out there, and now it has the new Indillinx controller which is amazing, and i love OCZ's products.

Upgraded Mid 2010 MBP from 250 to WD Scorpio Blue 500GB. Works great so far. Reason was online reviews and comments on the Scorpio and MBP. 5400 because of vibration, noise and battery drain concerns of 7200

I have a 13" MacBook Pro (October 2011). I've replaced the Superdrive with an 80GB SSD to compliment the 320GB HDD. I forgot to set them up in a RAID configuration, but I'll do that at another time. I do recommend that you either get an Apple authorized/supported SSD or modify some code to enable TRIM on the SSD.

I've placed the Superdrive into an external usb enclosure, an it works just fine. I did have to modify some code for playing DVDs from the external superdrive.

I upgrade my 2011 15" MacBook Pro to 8GB ram and replaced the 750GB 5400rpm drive with a 750GB Seagate Hybrid drive. It was relatively cheap ($119), I gained a LOT in performance and didn't sacrifice the size.

I upgraded my 2010 Macbook Pro's hard drive from 120GB (Sandisk SSD) to 500GB (Hitachi Travelstar HDD) as I make a lot of music on Reason and Garageband, and a lot of movies on Final Cut Pro and dual-boot Windows 7 on it. It's my music production laptop at school, so I keep it there, lol.
