Two 128gb SSDs or one 256gb ssd?

Before I start, I want to apologize for the headaches I may cause due to my lack of experience... I'm still learning :). 
Around a year ago, I purchased a 60gb SSD. The speeds were amazing, however, I found that the speeds have slowed a bit along with me running out of space all the time. (I have a 2TB hard drive as well for bigger files) Skip to the third paragraph where the bold text starts if you don't want to hear about my whiny first-world problems :)

 

I have been looking around for good Solid state drives, and it looks like the Samsung 840 PRO series seems to be the best. 
I need around 200gb of space, which both of those solutions will satisfy. However, I want sheer performance! I want to be able to read/write 50gb files as fast as possible. I like to record video game footage for extended periods of time, and I also like to edit from my SSD (which I can't currently do with big files). I would also like to reduce the amount of everyday files I have to use from my HDD so I can have it off and not hear it spin as often. 
 

Here's my question. Sorry if it's dumb. 

I'm not sure which would give me better performance. 

 

Samsung 840 Pro 128GBx2 in RAID 0
or 
Sansung 840 Pro 256 no RAID.

 

Please tell me which solution I should go with, and maybe a bit why? From what I understand, RAID 0 doubles performance so it would be best for me to just get two 128 GB drives. (That's what I have going on in my head right now, which I'm sure is completely wrong, but I would like a little insight on why? :). 
Thanks for helping me

RAID 0 ! DO IT! Still behind Linus' 8 but meh

I would go for the two. 

CPU: Ryzen 5 3600 @ Stock, CPU cooler: Dark Rock 4, Motherboard: MSI B450M PRO-M2 MAX, RAM: 2x8GB Crucial Ballistix DDR4 @ 3000Mhz, GPU: EVGA GTX 1080 ACX 3.0, SSD: Crucial P1 1TB M.2 + 2x120GB SSDs, Case: Corsair 110R, PSU: Corsair TX650M, OS: Windows 10 64-bit.

If you are still running Win7 I would go two drives. If you are on Win8, go single.

it depends really if you want to run in a raid or what? do you have lots of space? it's your choice i personally would go single!

Well anything that uses electricity inefficiently is going to produce heat. Just not much in the case of an SSD.

 

OP-Get yourself an EVO drive! Pro is not worth it in any case I can think of other than a business setting or some equivalent situation where data is being written and read constantly in massive amounts.

So it seems to me that the better performance option would be to go with the two SSDs. 

I have another question though. Considering that the dual SSDs is around 60 dollars more expensive than getting the single one, I'm just wondering how much of a performance increase would I be getting?

Would I be getting a 1.5x performance increase compared to the single SSD? 
I have also decided to go with an EVO drive instead of a PRO drive. I don't think the extra 100 dollars it would cost for the PRO is worth the performance increase.

you will be getting twice the performance (2x) because you will write half of the data on one of the ssd's and the other half on the other one

1 is actually cheaper too

I'm aware that going with a single SSD is cheaper, but I'm also a performance freak and would benefit from being able to copy/paste 50gb files as fast as possible. So RAID 0 with two drives is faster than one drive.

If you edit video on a daily basis get a RAID 0 with Pro-Drives.

If you do it only occasionally get a single Evo-Drive.

Also keep in mind you will only profit from this fast write/read rates if you are working on the ssd itself. If you copy data to a HDD the bottleneck will still be the HDD

RAID 0 only (almost) doubles sequential non-random write/read rates of large files. A RAID 0 (especially when done with software or cheap raid controller) can even slow down small and/or random write/read rates ...

Hm, now there's something interesting that I did not know... 

I am only going to be using an onboard RAID controller, which I'm going to assume isn't the best. The motherboard I have isn't anything special. 

How much would a RAID controller cost that would be decent at handling random read/writes? 

I think I might be considering just going with a single drive now unless RAID controllers capable of random read/writes are fairly cheap. 

Thank you for your post, MrSuperb.

8? That's cute.

 

So... If Jesus had the gold, would he buy himself out instead of waiting 3 days for the respawn?

The onboard controller will be fine for Raid 0.

That being said, ssds in raid 0 will only increase sequential transfer speeds but hwat makes a ssd feel fast is the random read speed nor the memory controller. Because of this, a ssd raid 0 array may end up slower than a single drive.

However, if you need the highest sequential transfer speeds, there's little other option. 

If that's not that big of a deal, a single 250GB samsung 840 (not the pro) will effectively be the same.
