Week 14 - Muddy

Another muddy week for me this was a lot of techniqual terms in this week that took getting used to there was a lot of information about storage however that can benefit a lot of people if utalized the right way

RAID
Raid stands for Redudant Array of Inexpernsive Disks and the main focus of RAID is to run multiple drives and treat them all as one. This will increase capacity, speed, and even reliability. It works a lot faster on Hardware then software. There is 4 including one new type of RAID
RAID 1 - aka mirroring
This means there is two different drives with the same data written on both of them which is good if one single disk fails you still have the same exact data with no errors backed up on the other disk, so there is no data loss and still runs at full speed. RAID1 also has a hot spare disk which is idle till one disk fails then it kicks in and backs up the data.
RAID 0 - Striping
Two or more drives and spreads the data across all drives evenly which makes the disk run a lot faster but there is no redundacy so if one disk crashes they all lose the data
RAID 5
This bridges the gap between RAID1 and RAID0. Data spreads across all disks except one which is used as a backup so it runs like RAID0 but if data is lost on one disk it runs like RAID1 and has back up disks to help out this one also has a hot spare.
RAID 6
Is a new version being started that is like RAID 5 but instead of running if only one disk dies this one can run even if two disks die.


There was a lot more information in this section as well which went into depth about the best storage choices for your business.
