Ok so if no one has any idea about that particular controller then someone must know of a site or mailing list that has info on these things??
Or even better what may work!
Other options I am looking at are the SONET Tempo SATA Express34:
http://www.pcwb.co.uk/catalogue/item/SONCA170 {which is a bit expensive}
Or alteratively:
StarTech.com eSATA 2 port controller:
http://www.pcwb.co.uk/catalogue/item/A0388114 {better value, much cheaper but not sure comparison in quality or why such big price differential}
If anyone has anything to suggest it would be really great as I'm soon to get something but have no clue of what... yet!!
Also since I am gona buy from one of those webstores a whole bunch of other stuff it just makes my life easier to get from one place but in real terms it doesn't actually matter!!
Many thanks for any responses :-)
