Mini PCI-e SSD for boot?

this is a great questions... i have been trying to research this issues for a few hours now. so far i found two individuals who have said it is not possible. however, i intend to buy a mini pcie ssd card and attempt this procedure myself. (imac 24" 2.8ghz).

FYI - Here is a link to someone who claims that their 2008 imac was able to read a mini PCIe SATA SSD: http://forums.macrumors.com/showthread.p...

So it seems there are interfaces which are physically identical to mini PCIe, however, differ electronically. For example, mSata can be had in the form of a PCI Express Mini Card-like connector, however, electrically it is SATA. So, unless the mini PCIe slot in the imac is wired as mSata (which it most likely is not - working to confirm this) than plugging in a PCIe mSata SSD will be fruitless. However, there is a RunCore Mini PCI-E PATA SSD which could possibly work and possibly others... looking into it within the next few days.

interesting info on that forum, so I guess we won't know before trying, cause he had success on 2008 iMac but not in 2010 iMac.

It would nice to know also random read/write parameters of PCIe mSata SSD. I mean if on my iMac 2006 is not much better than my actual HDD (which is 75/85 if I remember right) it's not worth it

My computer is a 2008 iMac running El Capitan.

I have installed an Iocrest JMB582 dual Sata card in the mini PCI-E connector (in place of the WiFi card) . At power up drive and directories and files can be seen briefly but drive then becomes disconnected and only seen after powering down and restarting. After powering off the drive by itself and then on again the blue LED, for the drive (on the JMB582) illuminates but nothing else happens. Does any one else have this issue or any advice on this issue?
