every now and then i heard people discussing about using PCIe lanes or not enough PCIe lanes etc, those are conditions IF you are using SLI setup right? other than that, i think your PCIe lanes are pretty much still have some left used most of the time??
RAID 0 is fast, but doesnt that also means it is very dangerous if something happens to your file? As it will be rendered totally useless....
and also i want to ask, does using SSD with a not-so-stable voltage (for example, living in an area where there are suddenly electricity outage every once awhile) will brick the SSD??

it's not just about multiple gpu setups. it depends on the purpose of that rig. there are some pcie-based stuff, like sound, video capture, nic, wifi, and raid/sata/usb/scsi cards, that can be added to the system to cope with needs. pci-e slots can also be used as a means to replace faulty integrated parts of a mobo.
mainstream systems (like 4790k, z97) usually have less pcie lanes than high-end ones (like 5930k, x99).
due to such limitations, different implementations are adopted by manufacturers to assign and distribute these resources that involve lane sharing (that means there are differences in the number of pcie lanes connected to each slot, something like this,

we all know the risks of using raid0. we cannot eliminate them, so just prepare for the worst:
1. use it as a boot/software drive, not storage. normally 2x 256gb should be good and large enough.
2. make sure you can recover from disasters, by keeping the latest system images outside the system. (it's much more time saving than doing fresh installs from scratch everytime)
3. store the data in hdd (non-raid), or nas.
bad power supplies will cause damage in electronics. it's better to use UPS in this case. (it's not just about ssd. every component in your rig will be affected and i don't think you wanna risk them too) laptops are relatively better. they have built-in battery for this purpose.
