Got a Lenovo X220 with a single HDD and a single partition that contain both OS and programs/data.
I don't have the original OS installer (ex corporate laptop) so my choice for a cheap update are
- install a small mSATA SSD and in some way clone there only the OS (need some trick I think such as create a new partition on my HD, copy there programs/data, resize the original partition with only the OS and next clone to the new SSD)
- buy a SSHD bigger than my present HD and simply clone the whole HD
I think the second SSHD solution will be the safest one, but I read all the compatible 7mm SSHD from WD, Seagate, Toshiba are 5400rpm models.
My current HD it's a 7200rmp, will I have a real speed increase?
