Are SSDs as reliable as spinning drives? Leo says yes. They are very robust and much faster. Will they wear out? Leo says SSDs use a technique called "wear leveling" to keep the drive consistently wearing and to extend the life of the drive. That's why Leo recommends using an SSD as the main drive, and storing data on a spinning data drive. Let the hard drive handle the constant read-write cycles, while the SSD handles all the performance.
