Re: Questions about RAID0, SSD and Ubuntu
In a word, no. In order to set up RAID, you need two identical drives. You can't get a larger hard drive, set the amount equal to the other drive as RAID, and then use the rest as a separate drive.
IMHO, the cheapest way to get better hard drive performance is to spend ~$100 (sorry, don't know the price in Euros or GBP) and get a 1 TB drive (or larger if you can afford it). If you install the OS on the outer part of the platters (i.e., in the "front" of the drive), you'll see improved performance because larger drives are designed to have faster access speeds (they have to in order to read/write that much data) and the outer part of the platters spin faster than the inner part.
For example, on one of my 1 TB drives, I have Jaunty installed on the first 100 GB and I use the remaining 900 GB as a data drive in NTFS so that it can be accessed by both Ubuntu and Windows. Granted, it is not quite as fast as my 2 x 74 GB WD Raptor 10K rpm RAID0 array, but it is still noticeably faster than if I were to run the Raptors as independent drives. So a modern 1 TB 7200 rpm drive trumps a previous generation 10K rpm Raptor.
