whitequark | I've just picked up a chinese SATA PCIe controller | 21:51 |
whitequark | it has 6 ports but can handle only 4 devices simultaneously | 21:51 |
whitequark | iow 6 physical ports but 4 ports on the controller IC | 21:51 |
whitequark | can you guess how would the user select which physical ports go to which controller IC ports? | 21:52 |
whitequark | hint: imagine the gnarliest, cheapest solution you possibly can | 21:53 |
wpwrak | cheapest solution: 2 ports are simply unconnected ? for "power only" :) | 22:24 |
whitequark | well, not quite | 22:27 |
whitequark | the answer is they put a jumper in a gap between 6Gbps SATA lanes | 22:27 |
whitequark | and you switch between int/ext ports using that. | 22:27 |
whitequark | I can't believe it works. I assume it works in at least some capacity. | 22:28 |
wpwrak | jumper. solid, proven technology. and don't all those fancy new high-speed bus thingies have some speed adjustment phase where they determine how fast they can safely go ? see. no problem then. your data will still flow safely. | 22:35 |
whitequark | "we make sure your eSATA external drive is as slow as your USB one" | 22:37 |
whitequark | "that is tradition" | 22:37 |
wpwrak | "fully compatible" :) | 22:39 |
