There are several different types of RAID types:
RAID 0 is a striped type array, meaning half your data is stored on one disk, and half your data is stored on another.
RAID 1 will keep the data on both the drives writing and reading from both drives, so if one drive fails, the other drive is still there, and the operating system can continue to operate as if nothing happened.
RAID 1 can be used, and they’re mostly for automated trading computer setups that require the Trading Computer always to be on, executing trades on your behalf. I would still recommend a backup drive in conjunction with the RAID 1, as the RAID 1 only protects you against drive failure, which is extremely uncommon. Ever since the third generation controllers for SSDs have been released, SSDs have much higher reliability and tend not to fail in the first 5 years of service. After the 5-year mark, failures among SSDs are much higher, and we recommend preemptively replacing the SSDs at that time to keep your trading computer running at peak performance and reliability.
There are also RAID 5 and RAID 6, which add redundancy to the striped array but are out of the scope of this article.
At Falcon, we don’t recommend using a RAID for most of our traders as Falcon has found that the Paragon Backup software is much more useful and economical because not only does it protect you against drive failure, it also protects you against Viruses, Windows Update issues, and platform update problems. This offers peace of mind that, whatever happens, we can get your Trading Computer up and running again as quickly as possible.
