Hello,

I'm upgrading some stuff on my laptop Dell Inspiron 15r 7520 and I'm in doubt about storage arrangement.
I bought a Samsung EVO 850 250Gb to substitute my HDD (1 TB). I erased all data on this HDD to use as secondary storage (in an adapter to DVD drive SATA port) and I installed a clean OS on SSD.
The doubt begins when I choosed AHCI mode on BIOS for my SSD (as samsung recomends to use RAPID MODE and to raise the performance of reading and writing), the problem is: My computer uses 32Gb mSata ( 12 Gb for cache and 8 as Rapid Start Partition) on IRST as factory default, aparently the only way to make it happen is using this SSD as RAID 0 with this mSata to "accelerate" the system.
If I use this configuration my SSD would decrease performance as RAID with an old mSata since my new SSD probably is faster?
If I still using AHCI mode, what I have to do with this mSata? For now it is unallocated and empty, this is the best way to make it?
What's the best choice: RAID to use this mSata, AHCI to use Rapid mode on magician , or just AHCI without rapid mode (since I just have 8 gb RAM)?

This doubt started when I changed HDD and I felt a little low performance for a SSD system, specially on windows boot and opening some app of Adobe, what make me think if there is some issue of using the storage arrangement that I choosed.

Sorry about this long text and all these asks, the most I read, more doubts and variables I have.

Thanks!

You want to use the 32GB SSD as a cache for the 250GB SSD?
Absolutely pointless. If anything, that would be slower than just using the 250GB on its own.

Samsung Rapid Mode, with only 8GB RAM? Don't bother. You're sucking up a significant portion of RAM for this Rapid Mode.
RAM that should be used for actual applications.
Change it to AHCI. Using a SSD to increase the speed of a SSD is pointless.

For the mSATA there are a few things.

1) By a USB 3.0 enclosure. Nice fast external drive!
2) You can use the built in windows feature to speed up the system as a whole
3) move your System page file to the mSATA so there is less wear and tear (more than likely the SSD will way out live the laptop to begin with) on the 850.
4) Give it away lol

And honestly for the whole RAPID mode thing I can't really chime in on as i have a Crucial SSD so I can't say if RAPID mode is really that much greater or not. On the System i have used with it enabled honestly I don't see a huge difference between RAPID and non RAPID mode Systems
