I am currently using this drive attached to a new iMac 27" maxed out on processor and RAM.. we have been in the field the last 3 weeks shooting a project bouncing the footage down to this drive from our firewire 800 card reader is quite fast.. once its on the drive playback is un hitched and speedy even using the compressed sometimes stuttering codec of H264...

We are now in the studio, and the drive is being used as our main edit drive for this project.. we have 2TB of footage encoded to Apple Pro Res 422HQ , we are playing back 4 layers of video through FCP and we see NO LAG, this drive is SPEEDY !!!!! Its built to transport if you have the appropriate road case with
shock support.. its just simply stunning how quick this drive is.. Thunderbolt is absolutely an amazing new way to interconnect devices, it will be the future of what everything is connected with , still faster than USB3 and blows away firewire 800....

The software that comes with the drive is a little clumsy but very intuitive, you can manipulate all of the drive properties from it, quick to install, but may take a minute to learn where all the attributes are..

When you first power the drive up, you will need to wait for an initilisation process to happen which took for me about 12 hours, so don't expect to use it right out of the box.

Overall i would and will absolutely buy another one of these drives.. Would totally recommend it to any AUDIO or VIDEO professional.

3.0 out of 5 stars not user friendly in everyday work, December 10, 2011

Basically it's a solid box, but in everyday work there are several limitations which make the handling cumbersome:

- the device has no sleep mode. this means that your discs spin all the time which decreases lifetime and increases power consumption
- it makes some noise so either sleep or power down would be nice while you do not need access (eg. when a backup finishes)

- when you power the device off, it breaks the thunderbolt connection to all devices behind it. in my case that is an external screen. so you have to replug things or leave the device always on - consuming power, increasing disc wear, making noise
This breaking of the TB chain makes it nearly unusable as a backup device which should only be mounted during the backup is made

- the software which comes has nice icons, but is hard to handle - I found no option to power down from the software side. To shut it down regularly you have to hold the power button for several seconds (like a reset on a mac). this is boring and does not always work

- the device only has a thunderbolt interface (2 plugs) - no USB, no network connection. This means you can only use it with apple hardware later then february 2011. there is no way to get to your data with older macs. this is a real limitation, especially in case of emergency when your thunderbolt machine breaks down and your older emergency hardware comes in

- the usage with bootcamp (for Windows) is not possible to my knowledge

the basic function of storage works fine up to now. but in day to day work it's limitations are annoying

Fast it is. Only reason at this point not giving 5 stars is because the documentation on how to change and reconfigure this drive is beyond skimpy. Took me an hour to figure out how to reconfigure and i am pretty good at this type of stuff.
