1. These Western Digital Disks are not the 'Blacks' I hope, but the enterprise 24/7 version, RE or SE. WD Blacks do not work reliably in a parity raid because of the WDTLER implementation.
2. The hot-swap bay has no use for hot-swapping, unless you want to rebuild the array with a new disk.
3. This Areca card is the best one for sale at this moment. Excellent choice.
I only have one drive now and it is a black. At this point I can buy any drives that someone would recommend would be the best for this application. I am not stuck on any size or brand what I would like to do is create the best raid3 so I will have the best performance possible. I do understand that the hotswap bay would not come into play unless I have disc failure. But I dont have room to put 5 hard drives in the case with out using them.
Good conventional disks for a parity raid are:
- HGST Ultrastar
- Seagate Constellation ES
- WD RE
CC_Merchant is correct. Don't use the desktop drives with a parity raid such as raid 3. Those enterprise class drives he lists are what you want to select from.
another question about the raid is from what i have read it will require a battery back up is this correct? and can i turn my computer on and off like i normally do it is usually off when i am not using it?
Rather than a battery backup for the raid card, I have a ups on the whole machine and the monitors. I turn mine off when not in use, using the power button on the ups, after, of course, shutting down the pc.
