How to know if an SSD can work in "IDE" SATA mode?

Yes, it will be slower compared to AHCI, but I see SSD as a better investment over HDD. Thus I just need it to work, I don't need extreme speeds and I don't need a huge amount of bytes.

Clearly some SSDs work in "IDE" mode as I've seen from threads like these http://www.tomshardware.co.uk/answers/id-1778026/find-ahci-bios-ide-effect-ssd.html http://www.tomshardware.co.uk/forum/284174-32-works-mode

But how do I actually confirm it without plugging it in? I've tried 850 EVO and I'm pretty sure it's too new for that. Preferably I would like to know if 750 EVO works in "IDE" SATA mode(though I doubt it does since it's one of the newer ssds too).

Hey there, gam-ma.

The SSDs should work under both modes. The SATA mode is not determined by the drive, but by the SATA controller's on your motherboard, which can be set to IDE, SATA or RAID. You can do that by accessing your BIOS/UEFI. Most SATA SSDs should have no issues working under both IDE and AHCI modes. In order to be completely sure that yours will be OK, you should contact the drive manufacturer's customer support and ask if there might be any incompatibility issues with your hardware configuration.
Something else which might fix incompatibility issues is updating your BIOS or updating the SSDs firmware.

Hope that helps.

A SSD will work perfectly well in IDE mode.
What you lose is the ability to pass the "trim" command to the ssd.
That improves update performance and ssd endurance.
One needs to select the sata mode before installing windows so you will get the proper drivers.
If you already have a windows install with IDE, and you clone your hard drive to a ssd, it will work perfectly well excepting for the aforementioned caveats.

Thank you guys for these answers and I'm really sorry... Contacting the manufacturer's customer support seemed like the most reasonable thing to do and they said that it shouldn't work - the same thing I heard in a lot of other places... but I just managed to connect 850 EVO 120gb to a DDR I (!) machine, with zero trouble. I didn't even touch the bios. I guess people these days avoid IDE mode at all cost, thus they don't know that SSDs work in both modes... Or maybe they just don't know what I'm talking about, maybe just a simple miscommunication.

P.S. So I guess the problem IS with the motheboard Foxconn K8M890M2MB-RS2H. I'm guessing it's unsolvable thus I will not make another thread...
