Yes but arguably anything below the equivalent of RAID6/RAIDZ2 puts you at a not inconsiderable risk of data loss. Most laptops cannot do parity of any sort because of a lack of SATA/M.2 ports so you will need new hardware if you want the resilience offered by RAID. Ideally you will want that twice on different machines if you go by the "backups in at least 2 different physical locations" rule.
