Hello,
When building a RAID array, are you limited to 2.19 TB for just each drive or for the total of the entire array.

Hey Jspckip,

It depends on the RAID controller card, hard drives and system you are planning to use. However, the total of the entire array does not have to be 2.19TB. That depends on the setup for the RAID. Most RAID controller cards should support up to 2TB per drive. Anything above is dependent on the system setup of your OS, RAID controller card, etc. For example, the OS's that currently generally show to support over 2TB as boot drives are: Windows Vista 64bit, Windows 7 64-bit and Mac OSX 10.5-10.6. As a secondary drive, most operating systems should be supported.

Hope this helps with your question.

Correct!

Even with 32-bit Windows, there are controllers that support
VSS (variable-sector sizing): this feature increases each sector
from 512 bytes to a maximum like 4,096 bytes per sector.

In the latter case, the volume can be 16 Terabytes, but
such volumes are limited to data storage, and cannot be
used as boot drives.
