The transaction log is divided into smaller data files known as sign extents. Each one is 64MB in size. Each sign extent contains an entry that indicates the date of creation of the database and the date it was last run by the Fixup program.
There are several levels of raid, and each offers various levels of performance and fault tolerance. RAID 1 is the most widespread, as it employs mirroring to basically double the storage capacity of an system. It’s not completely secure. It could take hours for the remaining drives to restore the data if the mirror disk fails. RAID 5 is a different option that combines striping with parity to offer excellent storage and performance. It requires two additional disks to achieve parity but offers the best balance of storage and efficiency.
