hello dear members,

i wanna buy an G-RAID by G-technology, and will of course be using it in RAID 0

http://www.g-technology.com/products/_images/g-raid/product-page_topper_graid.jpg

they say that with thier eSata adapter it can reach speeds around 230MB/s
http://www.g-technology.com/products/_images/common_products/pcie-x4.jpg

this eSata adapter is 320 dollars. wich i find a bit of a lot for just an eSata adapter. whats the difference between a normal eSata adaptor or one from G-technology? can i reach the same speed with a 300MB/s eSata adapter from a different brand?

thanks!

the price is the main difference :)

but the firmtek one which is good is about $200 for 4 ports

the ones from OWC that support PM cases are about $80 but they are two port only ? so figure $160 for 4 ports to compare price per port

the OWC ones or the firmtek will be good enough to hit the same speeds ? some cheap ones wont do as well ?

so actually it doesnt matter wich eSata adapter i buy aslong as its not a cheap ass one and it can transfer 300MB/s ? I dont need 4 ports thou. 2 is enough.

more like 220 to 240 max. 300 is more like a theory with a two bay piece. Still 220 is pretty good.

Yes i know. I ment a 3Gb/s eSata adapter (since theres also 1,5Gb/s and 6Gb/s)

can anyone recommend me a good one? or is there really no difference?

don't worry that it is a 6gb it is backwards compatible to a 3gb and it is on sale! 80 bucks.

I'd go with the newertech card that supports Port Mulitiplier enclosures ($80USD, here (http://eshop.macsales.com/item/Newer%20Technology/MXPCIE6GRS/)).
