(Or is it four, but one's the DVD?) This is what I've bought for my new PC https://www.amazon.co.uk/StarTech-com-Port-Express-eSATA-Controller-Silver-Black/dp/B00952N2DQ/ref=pd_ybh_a_47?_encoding=UTF8&psc=1&refRID=2B248DH9763DDGHGN5A6 An expensive gaming mobo, with 6 SATA ports, but if I want NVMe, or a second graphics card, or whatever whatever, some of the lanes get taken away. And of course I do want a 2nd graphics card (this machine is destined to be double-headed, when I can get it to work :-) And then for my old system, I'm planning to buy https://www.amazon.co.uk/gp/product/B07T8XNQT6/ref=ox_sc_saved_title_2?smid=A32IGEZ3DX93HZ&psc=1 or something similar. That machine has 5 SATA ports (or only 4 if PATA-mode is enabled), and I'm planning to stick a bunch of 500GB or 1TB drives in it for playing with. So especially if I split the 1TB drives into 500GB partitions, that's some humungous raids for testing with :-) Cheers, Wol
