SSD's in RAID spanned over different controllers.

[Aelneri]

Hi.

I have seen many videos showing that raiding 3,4 etc SSD's does not give a boost (in terms of MB/s read/Write).

3 Things I Wonder about:

1: What about SSD's spanned over multiple Raid-Controllers?

Will the use of one Raid-Controller on the motherboard limit the Maximum read/Write from the SSD's?

Will it help to have 4 different (inexpensive) Raid-Controllers for 4 SSD's?

 

2: What about IOPS?

Will raiding more disks help on IOPS if it doesen't help With read/Write?

 

3. Windows (Dynamic disk) Software Raid.

Is it OK to use (performance wise)?

 

 

I do not have Access to huge amounts of SSD's and Controllers to test these things, so any input would be appreciated.

 

Case scenario is:

Any motherboard With 2 Controllers for sata-drives (Mine is: Socket 1150 - GA-Z97X-Gaming 7 )

Any Processor (Mine is Intel Core i7-4790K )

Any Graphics Card (Mine is ATI (AMD) Radeon HD 7850 )

Any 8GB+ memory. ( Mine is Crucial DDR3 Ballistix Tactical 32GB 1600MHz memory CL:8-8-8-24)

Sata - SSD drive for OS

4x (sata) SSD's (available)

2x raid Controllers (the cheap ones without buffer and memory)

( Performance Low Budget computer)

 

What I want to achieve: Faster/lower loading times in games (Fallout4 /GTA V).

 

Bottom line: Will loading times be better With SSD's in raid spanned over many Controllers be better?

Or are the SSD's performance (in total) Limited to the CPU/chipset ?

Or are there any other modifications that will improve the loading times?

My research shows that a RAID 5 is your best option for performance with 3 or more SSD's. They should all work on the same controller and I do not think you can run any kind of RAID using different controllers unless they are entirely separate RAID setups.

@Columbo Thanks!
Have you any idea if there is a big difference in Windows Dynamic raid and Controller raid?

(Windows 10 only supports Raid 0 and Raid 1)

Use the RAID controller built into your motherboard. The software is built into the bios. The other way is expensive RAID controller cards that usually cost hundreds of dollars. The Windows Dynamic RAID is a joke. I think all the motherboards that are not low end offer RAID 1, RAID 0, RAID 5 and RAID 10. The last being on higher end boards. I have been running RAID 0 since 2007/2008 and have yet to have a HDD fail on me or a RAID array somehow compromised with errors that led to a loss of data. I have used the motherboard controllers for my RAID O's. I ran two separate RAID O's on my setup in my signature. One was a spinner RAID 0 and the other a SSD RAID 0. 

 

Below was my Toshiba RAID 0 with 128GB SSD's.
