    I’ve bought a RR640L, and found out that it doesn’t support bootable raid in OS X. Since RR642L was on the El Capitan support list (http://www.hptmac.com/support_el_capitan.php), I though that RR640L can also achieve a bootable raid in El Capitan because they used the same Marvell 88SE9235 chip. After a few hours of work, I successfully replace the product S/N in the RR642L EFI rom to fool the WebGUI into accepting it. Now, I’m able to boot with 2 SSD raid 0, but the write speed is slow. I've test these SSDs within windows 7 before, they can both reach 400 MB/s write and 500 MB/s read.

    Any suggestions? Raid cards which officially support for both OS X and sataIII are too expensive…

    RR640L with M4 128G non-raid is same as your situation, slower as 1XXMB/s!
    BTW, could you pls share your rom? My RR640L cannot boot in El now.
