I experienced a complete SSD failure this week on my laptop. I've ordered a new Dell XPS 17 laptop which has an eSATA port. Given the nature of the SSD failure I experienced, from now on I wish to have my laptop running a RAID1 setup via the eSATA port when its used on my desk. However, when its not used on my desk, I wish it to function normally without the RAID functionality. Question 1. How does one set up a "sometimes" RAID ? Or would something like rsync be better ? What happens the first time I plug my laptop into the eSATA cable after being away from my desk ? What happens if there is both new data and an error in existing data ? How does the RAID software know the difference ? Question 2. Internally, my XPS17 has 2 hard drives. I will probably use an SSD for the OS and a 750 GB 7200 RPM conventional drive for data. How does one configure the single external eSATA RAID drive to back up (mirror) the data for both internal drives ? Question 3. The OS drive will be an SSD which is faster than the eSATA RAID drive, which will probably be a 7200 RPM 2TB+ conventional drive. Will this limit the speed of the SSD to that of the eSATA drive or is buffering employed to allow one to be faster than the other ? Question 4. Can only a portion of the eSATA RAID drive be allocated to the RAID and the rest left to be mounted by the laptop for general access ?
