SSD v SSD in raid v M.2 NV and other exotic Hard drives, speed differences between all ?

yes im looking for input for load boot and game load times between basic ssd drives 500 mbps r/w to nv m2 960 pro 3200 mbps r/w, have u noticed much difference in system loads times etc.

well going from a standard hd to 500mbps with ssd drives i thought it was pretty dam quick and then i setup a raid configuration and this really wasnt that much quicker then 1 ssd drive, ur experiences with M2 etc is it really worth the money cause single drives now are getn cheaper.?

Putting multiple SATA SSDs in RAID-0 basically nets zero real world difference in feel of performance in a single (logical C:\) drive system. If you've got multiple drives in your system, like 2 RAID-0's of SSDs and a C: and E: drive in windows (for instance) then large single file transfers will be quicker, but copying large loaded folders of files really won't be (that's where IOPS come in to play). By putting multiple SSDs in a RAID-0 you're also technically doubling your chance of loss of data due to potential drive failure.

Where the huge gain with NVMe is, especially in a single physical disk system is in IOPS. This is what really gets you the gains. Like SoggyTissue (LMAO btw...) said however, real world feel between SATA...

going from HDD to SSD nets biggest difference, a 10 second game load will take maybe 3-4 seconds (initial load)
going from SSD to anything else will only reduce the 3-4 second load to ~2 (initial load)

this is just a general rule based upon world load times in World of Warcraft. ( i have on SSD and a copy on HDD, i can stopwatch the load times ).
this is only based upon my pc performance ofc. I have never owned a m2 but you can see from the average read speeds compared to a ssd.

m2 ave reads are 3100mb / ssd ave reads are 500mb - on paper 6x faster (and i would love to see WoW load in under 1 second but i know that just wont happen?) *i would assume you could get a 3-4 second load time down to 1-2 seconds with m2*. raid SSDs in mirrored? think there was a news article in the feed about a raid SSD array set up that made load times insane, but also insanely expensive.

Like SoggyTissue (LMAO btw...) said however, real world feel between SATA and NVMe isn't going to blow you away anywhere near what HDD to SSD did. You can feel it though, for sure. It also depends greatly on not only what SATA SSD you're coming from but also what NVMe SSD you go to. Some will feel absolutely zero gain as some NVMe SSDs barely have any increase in IOPS over good SATA SSDs.

Your question is kinda loaded...
