first off it runs loud. second it is fast. at least when i pulled the stock 500gb hdds out and put in a pair of samsung 256gb series 470 ssd's run in raid0. actually those scores are pretty good and I am sure a pro could use that speed and large storage size in a small space. doing this mod kills the warranty, but buying a seller refurbished unit on ebay would allow a square trade warranty. this build is far faster then lacies 240gb ssd unit. I would give a link to a famous auction site but I have not put it up for sale on ebay I may sell it and if I did it could be covered by square trade warranty. (as seller refurbished) very annoying that you can't diy one and keep it under warranty ( lacie voids the warranty if you open the unit) but you can sell a diy one and give a square trade warranty to the buyer. here is a link to the 240gb ssd review cost 899 plus tax. http://www.anandtech.com/show/5066/lacie-little-big-disk-240gb-ssd-review this 512gb unit can be built for about 1k only 100 more then the slower smaller lacie 240gb ssd above. I tested this with a pair of kingston 64gb ssds these pull more juice I tested this with a pair of samsung 830 ssd's 64gb size. these used 5 watts at a low load and 8 watts when they overwrite zeros same as the 470 series 256gb ssds tested above. Others have written that 500 to 550 seems to be the max speed for one unit. they have a bridge and I think they would max at 520MB/s. this means good sata II ssds will work fine inside of them. I also found you can pull one hdd out of it and put in one ssd. they use your machines raid setup you can do raid 1 raid 0 or jbod. It is a nice piece of gear if you mod it with the samsungs. 8 watts is low power use. and that is with a zero over write 5 to 6 watts is normal. I was lazy and did not try to use a fw800 to dc jack other then the one that works with owc's unit here. http://eshop.macsales.com/item/OWC/MEPMPWR12VF8/ this does not fit and I only had the one from lace's power supply I was not looking to cut it. I will play with it tomorrow as I am sure you can get that to work as long as you don't daisy chain .
