A friend of mine has a T530 (I think he bought it last year) and I checked the spec it seems to support RAID 1 (mirroring). He currently has one hard disk running and is considering RAID 1 and is also considering buying a SSD as a faster drive. I don't have much knowledge on either.
Is it possible to use SSD as THE drive and use the current disk as the mirror?
If it is possible, would performance benefit he would have gotten from using the SSD versus that of the hard disk be throttled to the speed of the disk because the system has to make sure the mirror integrity?
