Reaching External Drive 4TB

Nothing like going to visit Fry’s on weekends.
I sure love their sale items. I was thinking to purchase larger ( 3TB or bigger ) external drive, but it was still pricey. Not this Saturday though, Fry’s had on sale 4 TB External disc for $237.49. Finally that was affordable for me. I have many photos, I go through a lot of external drives, and USB no longer fast enough, especially when I am working on large photos. I almost filled up my 2 TB Iomega, I needed bigger storage. If you are a photographer, you go through external disc pretty quickly. I think 4 TB will do good for me, at least for a while. At last I can compare the speed of USB vs Firewire 800.
For just my curiousity I benchmark it before I start using it.
I use for that. The result is 75.85.
Previously I was using Iomega 1 TB, Firewire 400, the benchmark was 40.3 and another 1 TB external disc.
Seagate firewire 800, 1 TB the benchmark was 58.
My internal disc ( iMac ) 76. I would say that is pretty good.
I think I will see less and less spinning of death waiting period.
I must say I am so impressed with my MacBook Air benchmark result was 219.77!
That is the difference of solid state drive.

Pros: Well built, fast external hard drive, works well with MAC.
Cons: Noisy. It is loud when it is working. But if you have a closet to hide, then fantastic bargain!
