===Criticism===
The Mac Pro RAID Card Battery, also used in Apple's Xserve RAID, was criticized for its short life span and expensive replacement cost. Repair by end users was also noted for being difficult. The required replacement component is a 606168 rechargeable (Li-ion) cell, also referred to as (LiPo). Mishandling of components containing such chemicals is very hazardous.Apple Xserve/Mac Pro RAID Card Battery Repair by Dan, iFixit. 2016-09-29.
Neither RAID Card can recognize more than 2.2TB of a larger SATA drive, though larger SAS drives are not an issue.
