shoarthing Posted December 22, 2014 Share Posted December 22, 2014 Hi - the aim is bootable SATA3 for a SSD; but I have PCI-e v1.x only - a (physical) 16x (electrical) 8x slot is available. PCI-e v1.x (only) means I need an HBA that multiplexes 2 or more of its 250MB/s lanes, & whose controller IC accepts one or more PCI-e v2.x or greater lanes as input. I cannot find an adapter using the popular asm1061 that also multiplexes 2 or more lanes. A non-multiplexed asm1061 is useless to me, since this controller has single-lane input only. A fair bit of searching turned up either the full-on Rocket Raid 640, or the (cheaper) StarTech PEXSAT34 - both require a 4x (physical) slot, both use 2x Marvell 88SE9128 controllers, and both have a PLX multiplexer between the PCI-e lanes and their single-port input; tho' the Rocket Raid has the full-on PLX8069, and the StarTech the 4-point 8064. It is pretty clear from reading the component specs that the StarTech (no longer in production, but available) is almost certainly a 2-lane device only: has anyone here used one in a PCI-e v1.x system? Did the thing manage greater (single channel) read performance than the usual Intel SATA2 of around 240MB/s? In the alternative; does anyone know of an affordable SATA3 2-lane or greater HBA, with native support on OSX 10.x; that definitely works in a PCI-e v1.x multi-lane slot, and that definitely multiplexes its lanes to one controller's input? . . . especially interested in firsthand reports from users (in a multi-lane PCI-e v1.x physical environment) of 88SE9230-based HBAs like the Highpoint Rocket 640L running a single SATA3 SSD - appears to give mediocre performance in WinWorld; but mebbe native drivers in OSX are better? NB 'affordable' = no LSI or similar devices. Link to comment Share on other sites More sharing options...
kvonlinee Posted December 22, 2014 Share Posted December 22, 2014 I was searching something similars that also, after a while I just got new motherboard and ssd to speed it up, too tire to search. Good luck. Link to comment Share on other sites More sharing options...
shoarthing Posted December 22, 2014 Author Share Posted December 22, 2014 Mmmmmmmm . . . kinda misses the point of hacking (to me); but, yes, always fun to buy a pile of today's exciting bits 'n bobs. Which HBAs did you look closely at? Link to comment Share on other sites More sharing options...
kvonlinee Posted December 22, 2014 Share Posted December 22, 2014 That was wing something, it can be raid on 2 ssd, it was hard to buy it, then i dropped, someone report it was bootable by osx. Apple never give out full hardware detail, so for hack is trying and see. With exotic thing like this, only try and see. Link to comment Share on other sites More sharing options...

Really neat. Requires drivers. Link to comment Share on other sites More sharing options...
