Got a 128GB mSATA SSD for my Thinkpad, as my cache read percent was consistently under 10%. Writing this post because I could not find any documentation online about replacing your mSATA SSD online.
So, a couple of things you need to know about replacing the mSATA SSD on your Thinkpad Twist
- The cache partition has a limit of 32GB
- You still need to set aside space (Size of your RAM + a bit more space[I gave it an extra 256MB]) for Intel Rapid Start Technology(RST) (The thing that makes Windows start up faster and recover from hibernate faster)
- You can use the remaining space as a SSD
Steps to replace the mSATA SSD
- Buy a mSATA drive of your choice. Recommended size to make full use of the cache and Intel RST: 64GB, more if you want SSD space as well. I went with the ADATA XPG SX300.
- Delete the expresscache software from your computer
- Unscrew the 2 screws at the base of the laptop that has the keyboard logo beside it.
- Remove the keyboard by following the guide (http://schabby.de/lenovo-thinkpad-keyboard-removal/)[Caution! Do it slowly and don't pull it out too hard]
- The mSATA slot is on the top left corner of the motherboard. Unscrew the screw that keeps the mSATA device down, and it will pop up.
- Extract the card out of the slot, and put in your new mSATA SSD into the mSATA slot.
- Put the hardware back together.
- Now the fun part. The installation of the drivers and making things work.
- Boot up your machine, and install expresscache available at http://download.lenovo.com/express/HT074404.html and install it. The Win7 and Win8 versions are the same. The installation will create a partition for the cache using whatever remaining space there is on the mSATA SSD up to 32GB. Reboot.
- To make it support Intel Rapid Start Technology, follow the guide over at http://download.intel.com/support/motherboards/desktop/sb/rapid_start_technology_user_guide_v11.pdf
- And there you have it, your new mSATA SSD is now operational on your computer. If there’s extra space, you can create a simple volume using the Disk Management (Windows) software. [Win-x, and select Disk Management]
