The Seagate GoFlex Thunderbolt adapter has finally gone on sale in the UK and I received mine this morning
For those who haven't heard about the product, it's a small docking base for any hard drive in the Seagate GoFlex family (there are two sizes, I am referring to the portable, laptop powered ones). It requires an Apple Th'B cable, making the overall package pricey but you just need one base/cable for all your drives. I chose this option because, for the time being, Thunderbolt-equipped users can only buy the bulky and expensive LaCie drives or the very fast but very small capacity Egato SSD.
The test was very straightforward: copy 6 Gigs from my MacBookAir's SSD to a GoFlex 1TB - oddly, Seagate doesn't provide rotational speed for their drives so not sure if it's a 5400 or 7200, I suspect the former.
I started with the USB 2.0 : 3min52s Not bad
Then the Thunderbolt: 1min54s almost exactly half the time...
No idea how this compares to FireWire or USB 3.0. I assume the bottleneck is the HD. As SSDs get cheaper, then the benefits will get more obvious.
My conclusion: for MacBook Air users it's a no brainer. For others who have access to FW800 the improvement may not be that obvious until you attach an SSD...
