4 SSDs RAID 0 integreted vs dedicated controller

1

I've been thinking about setting up 4 SSD RAID 0 to gain performance in my home PC, and I ran into this review of PCI-E based SSD.

If I use PERC H310 (8 lane PCI-E 2.0 RAID controller, which means theoretical maximum of 4000MB/s) and 4 60GB SSDs it's still half price of that PCI-E SSD.

Since It's basically a RAID controller with separate SSDs on board, in theory it is possible to reach similar speeds with 4 x 60GB 400MB/s capable SSDs in RAID 0 configuration.

Is there any real benefit in using PERC H310 instead of AMD integrated SATA controller, I'm talking high-end chipsets like A88X and 990FX ?

I know the answer in theory, but does anyone have any real world experience with this kind of setup?

I am not sure if there is any SATA RAID controller out there that will provide you with the speed which you anticipate from 4 SSDs in RAID 0

I highly recommend watching this video for an excellent explanation: http://www.youtube.com/watch?v=27GmBzQWwP0

Basically, SATA-bound SSDs in RAID 0 still have to go through some sort of bridge either on the Motherboard or the dedicated RAID controller and that bridge has a maximum throughput which is usually reached rather easily.

Using PCI-e SSDs in RAID 0 will produce nearly boundless speeds.

After some more research, and as shown in the video above, I'm gonna go with 3xSSD as the fourth one doesn't increase the speed that much, and having 3 means less chanse of failure. – Enis P. Aginić – 2014-09-15T06:08:02.680

@EnisP.Aginić Have you done it? Did you use PCIe ? – Pedro77 – 2017-07-30T19:25:23.827

1@Pedro77 No, I didn't go for PCIe, but I did try with 2xSSD first. I could hit roughly R:850 W:700 MB/s but to be honest I didn't see any huge real-world performance increase. I did try to add a third one but it didn't run well as I had some freezing issues. Anyway – not the best option, you are probably better off with one larger SSD or going with NVMe. – Enis P.
