my Mac has Thunderbolt.

i'm looking for a Thunderbolt enabled external HD,

or do i need a raid?

i already own a 1TB G-Tech external HD,

and a 500MB G-Tech portable HD.

i don't keep my photos or videos on my computer.

You noted that you don't keep your photos on your computer.  I understand that to mean that you don't store your photos on the INTERNAL drive on your computer but only on the two externals that you mentioned.  Is that correct?

I believe that the 1TB G-Tech device is only available in USB 3, with only the larger G-Tech devices being available as Thunderbolt.

First question is whether you have one of the new Macs with USB 3 ports or if they are only USB 2.  If they are USB 3, you can already reach the maximum transfer rate to your HDD without using Thunderbolt.  I think G-Tech uses a 7200 rpm Hitachi, which is not fast enough to make maximum use of the Thunderbolt connection or the USB 3 either.  If this is your situation you can save some money and use USB 3 without losing transfer speed.  You would need a very high end HDD or an SSD to avoid the slowdown at the disk.

If you have USB 2 ports and Thunderbolt ports on your computer you can gain some transfer speed by upgrading to one of the 4TB or 8TB g-Tech Thunderbolt Raids.  Google RAID levels and you will find some valuable information, as there are several possibilities.

A RAID can be configured to give increased speed, increased capacity, or increased reliability, BUT IT'S NOT A GOOD BACKUP SOLUTION.

And I'm guessing a backup solution is really what you are interested in creating.  That means a copy of your data located remotely.

Apologies if I wandered off without actually addressing your question, but I hope that helps at least a bit.

One day long ago, a sorcerer and a warrior did battle, as such things were commonplace in that age. Sometimes the sorcerer won, and the sum value of human abilities was improved some trifling amount. Sometimes the warrior won, and again the human race improved by some insignificant amount, for a sorcerer who can't defeat one miserable warrior is a poor sorcerer indeed.

thanks so much. so comprehensive. i don't have USB 3. only Thunderbolt. i will be shooting only RAW and 1080HD video. based on my original post stating my equipment, what would u suggest. also, i didn't understand what you meant by RAID "levels". isn't a RAID a backup system as well? very secure?
