What form factor options are available for HDD

• 2.5" & 3.5"

• 2" & 3.5"

• 2.5" & 3"

• 2" & 3"

Distributes data evenly across all drives BUT data is also mirrored

Requires a minimum of 4 drives and a pair of drives is configured as the mirror.

Offers both speed & redundancy but at a higher cost of buying more drives

• RAID 1

• RAID 5

• RAID 10

• RAID 0

When shopping for a hard disk drive which would be the better choice if you want a drive with the most capacity and the highest spindle speeds?

• WD Gold 1TB Enterprise Class Hard Disk Drive - 7200 RPM

• Seagate IronWolf ST4000VN006 4TB 5400 RPM

(a)   is when multiple drives are utilized for data protection at the same time providing fault tolerance and redundancy
