Mac Pro 2009 with a Highpoint RocketRaid 640L raid card


i’ve bought rr640l, , found out doesn’t support bootable raid in os x. since rr642l on el capitan support list (http://www.hptmac.com/support_el_capitan.php), though rr640l can achieve bootable raid in el capitan because used same marvell 88se9235 chip. after few hours of work, replace product s/n in rr642l efi rom fool webgui accepting it. now, i’m able boot 2 ssd raid 0, write speed slow. i've test these ssds within windows 7 before, can both reach 400 mb/s write , 500 mb/s read.

suggestions? raid cards officially support both os x , sataiii expensive…

rr640l m4 128g non-raid same situation, slower 1xxmb/s!
btw, pls share rom? rr640l cannot boot in el now.
