RAID technology is a great feature for Lotus Notes that protects information in the event of a failure of the hard drive. It incorporates multiple hard disk drives into a single file system, and utilizes fail-tolerance to restore information in the event that one drive fails. It's especially beneficial for businesses which have multiple hard drives and want to ensure that their data is always accessible.

A typical raid setup is comprised of two or more hard disks and each has its own data path. It also has a transaction record, which is usually divided into scaled-down files called log extents. These files are typically 64MB in size. The Notes Machine supervises the transaction log.

Raid has been around for decades and is an important part of all datacenter systems. However, it's far from foolproof. If more than one hard drive fails, the whole filesystem may become unusable.

Despite its flaws some organizations still rely on raid to safeguard their data. RAID's latest versions, like erase codes are https://advancedexamples.com/2020/06/13/new-applications-and-solutions-through-raid-technology/ more effective in protecting data and providing more performance. However, they do cost more than traditional raid solutions.
