two 500 G Drives on Raid 0 or 1 = 500G (Not 1TB)

Faster read not write.

@brutusunix Raid 0 is data striping with no redundancy and 2x failure rate possibility. Size is based on the smaller size of the two (or more) drives. Two 500 GB drives in a Raid 0 config will yield 1 TB of 'scary storage; - larger volume, no redundancy. Raid 1 is mirrored - what is written to drive 1 is also written to drive 2. A pair of 500 GB drives in a Raid 1 config yields 1 volume of 500 GB, with redundancy.

When will we be seeing the mac pro unboxed alfred? its been sitting there for a fair time now get it out of the box for us!!

Dear Alfred, please, for God's sake, stay away from hard drives. Load up on RAM and you'll avoid 99% of the problems you mentioned. If you are writing a 50GB file to a hard drive, then make sure you have at least 32GB of RAM. That's a bare minimum amount of RAM for a 50GB file.

Why so much RAM? Because the file size you write to the hard drive dictates the amount of RAM. You would never have those catastrophic HD failures if you had enough RAM. Hard drives are too slow and very error prone.

Worst data loss: Accidently deleting my Fallout 3 save files from my Xbox 360 HDD, besides that, never loss data...yet

@dxproductions100 Corsair.

@dxproductions100 The Raid Array's brand is "SohoRAID"

[macprorocks]

@dxproductions100 Yes, but it was 1 month old.

JUST USE CARBONITE WITH A TWIT PROMOCODE

To prevent any more horror stories like my Garageband lost data, I did buy one FF-class 1To external drive. After checking it out with Time Machine, I eventually formatted the 500 GB to clone the whole freakin' system. So that's how I found my way to redundancy.
