So I have a pretty old Acer Aspire M5 481TG, with a 20gb cache mSATA + 500gb HDD. I've been thinking on replacing either drive with an SSD because the system is getting pretty freaking slow.

I could do:
1) replace HDD with a 2.5" SSD and get rid of the cache mSATA
2) replace cache mSATA for a bigger mSATA (probably a 250gb one) and make it the OS drive, and keep the 500gb HDD for storage

I'm leaning towards number 2 because though I'd like a faster OS drive I would still like to have some more storage. Now I've never replaced laptops drives and really have no idea how to do this and deal with the existing cache mSATA (seems to be using intel's Rapid Start Technology), or if number 2 is even possible at all. I have taken a look inside and the mSATA is pretty accessible though I'd need to take off some tapes wich is totally fine for me because the warranty is long gone anyways.

I would appreciate some help, and if possible a thorough step-by-step explanation as I'm fairly new with this. Thanks.

So I have replaced the cache SSD with a new mSATA SSD, and successfully installed Windows 10 using a USB boot drive. one thing to note is that I had to remove the HDD first and let the mSATA SSD be the only drive besides the USB to let me install into it.

Now my problem is, I can boot just fine into the mSATA's SSD Windows, but only if the HDD isn't connected. If the HDD is connected it will switch the boot drive automatically into the HDD, and if try to switch the boot order through BIOS Boot Priority while HDD is connected the SSD wont show up.

I suspect it has something to do with Intel's Rapid Start Technology that is intended to use the mSATA only as cache device. Since I intend to keep the HDD for storage I need to allow both drives to work together but cant seem to find any option to disable RST from the BIOS.

Anyone have any idea what I should do?
