SuperTrak EX Series User Manual

RAID 6

	Advantages	Disadvantages

	High Read data transaction rate	High physical drive overhead –
	Medium Write data transaction rate	equivalent of two drives used for parity
	Medium Write data transaction rate
	Good aggregate transfer rate	Slightly lower performance than RAID
	Good aggregate transfer rate	5
	Safest RAID level	5
	Safest RAID level

Recommended applications for RAID 6:

•Accounting/Financial

•Database servers

•Any application requiring very high availability

RAID 10

Advantages	Disadvantages

Implemented as a mirrored logical	Very high physical drive overhead –
drive whose segments are RAID 0	uses only 50% of total capacity
logical drives
High I/O rates are achieved thanks to
multiple stripe segments

Recommended applications for RAID 10:

•Imaging applications

•Database servers

•General fileserver
