Like the title suggests: Are 2 SSDs in RAID 0 too fast for the north bridge frequency?
My system set up for the components in question:
a. 2 SK Hynik Platinum P41 500GB NVMe M.2 SSD install in the Asus Hyper Card in a PCIe 5.0 slot, set up in RAID 0 in BIOS as the OS drive (C: drive)
b. 2 Samsung 990 Pro 2TB NVMe M.2 SSD install in motherboard M.2 ports, set up in RAID 0 in BIOS as Data & Media drive (D: drive)
c. 1 Samsung 860 QVO 4TN SATA SSD, set up as a backup drive (E: drive)
d. 32GB (2x16GB) Corsair Dominator Platinum DDR5-7600 RAM
e. DataRAM RAMDisk (RAM as Virtual Disk) 4GB, set up as "Temp" drive (*.tmp, *.temp, Temporary Internet Files, Edge cache, etc.) (Z: drive)
According to CrystalDiskMArk 8.0.4 x64 runs, my RAID 0 drives are FASTER than my RAMDisk. I'd post a screen shot of these results once I figure out how to do that.
C: 13554.73 MB/s reads, 9317.05 MB/s writes (RAID 0)
D: 13958.78 MB/s reads, 12744.41 MB/s writes (RAID 0)
E: 561.50 MB/s reads, 529.26 MB/s writes (SATA)
Z: 10764.17 MB/s reads, 20983.68 MB/s writes (RAMDisk)
I once had the ASUS RAMDisk installed, and it posted as Y: 17534.73 MB/s reads, 27305.21 MB/s writes (quite impressive!).
I also once had the 2 SK Hynik SSDs in RAID 0 , used as the "temp Drive" posted as: Z: 11804.89 MB/s reads, 9144.34 MB/s writes.
Running CPU-Z, my NB Frequency is 4600-5000 MHz, Memory Controller Frequency is 1800-2000 MHz, with the memory listed.
A quick look at these numbers shows that my RAID0 drives are faster than my RAMDisk in reads, the write numbers might be a little skewed, but RAMDisk writes slays RAID 0.
I know MB/s don't equate to MHz, but my system seems to hang at times when launching a new "app."
This system hang was so irritating that I removed the RAID completely, and now have the 2 Samsung drives stand alone in the motherboard PCIe 4.0 M.2 slots, as OS & Data & Media.
Now with the new PCIe 5.0 M.2 SSDs coming out, the RAID 0 are still faster than the current one out there.
But as these get better, they SHOULD eclipse the RAID 0 PCIe 4.0 SSDs figures posted. (Just wait until Samsung comes out with PCIe 5.0 M.2 SSDs!)
Will these be too fast also?
And what I mean by "too fast" is: are the drives read/write speeds faster than memory can write/read the information to/from them?
I know something has to be the bottleneck, but I've experienced "system hangs" (failures to launch apps, have to click multiple times).
I've decided against getting the new Crucial T700 PCIe 5.0 SSDs right now, mainly due to the heat issues. I'd have to install aftermarket SSD cooling blocks and fans.
A bit too complicated, just to test the new drives. I like to follow the mantra: Keep It Simple Stupid (KISS). And pricey for "testing."
