For Black Friday I got the Predator Helios 300 (256gb ssd, 16gb ram, gtx 1660ti)

I was kicking around the idea of doing a raid0 with a couple of the Samsung 970 Evo 1TB drives. After doing some research, which wasnt easy (for me)- I found this uses an Intel HM370 rev 10 chipset. From what I could read, this has max 16 lanes to the CPU (i7-9750H) and I would essentially be limited to only 4x on the entire raid array. One of these alone, as a single drive, are nearly already maxed out on the bandwidth.

So what i'd like to know/confirm:

1. Is this in fact the case, or would each raid drive have their own 4x, allowing me to double my performance in Raid0?

2. If I ran them as individual drive, would they operate separately at full speed, or would I still be limited by the 4x, meaning, it would still not allow me to use both drives simultaneously?

3. Anyone know if the chipset provides its own dedicated raid bus? Have its own lanes? If so how does this connect back to the CPU?

This link gave me the most info I could find in one place: https://valid.x86.fr/gljac9


Storage (HDD/SSD)
Model #1 Capacity: 238.5 GiB (~260 GB)
Model #1 Type: Fixed - Bus: RAID (8)

238.5 GiB = 256087 MB (is this per second??)

If that's the case, wouldn't that mean two of these at 3500MB could stack in raid0?



Looking for advanced technical info or diagrams or results from anyone that has done this already.

gotta say, I'm disappointed nobody here found the info before I did. I'm a novice at this stuff. But here is the answer for anyone else that finds this thread in a google search:

Scroll down to overview section, it shows it right there.

The pathway from the M.2 slots back to the CPU is only x4, so raid 0 wont give any extra speed if you're already getting 3500MB/s nvme speeds. max is 3900MB/s back to the CPU, and this includes the 2.5 inch Sata SSD drive bay.

If you wanna maxmize this with raid0 to save $$$, get cheaper drives that have a max speed of 1700MB/s each, in raid0 they will be at 3400MB/s and will leave plenty for a 2.5 inch Sata SSD that runs at 560MB/s.

Less buck for your bang lol
