SSD PCI-E or not?

Just want to make sure i make the right choice as i will not be looking to buy another SSD for a while after this purchase.

Id go cheapest per gb...as they are same class devices...the samsung 850 has the edge in performance..but the 840 firmware debacle may put some off samsung.

Yeah i have been doing some googling to see if the firmware problem carried over to the 850s but they have not been out long enough to determine if that is the case.
 
The mind boggles, now i do not know wether to get two 500GB SSDs or a 1TB SSD. My reason for two is to replace my old 128GB 840 pro.

i would go for 1x1tb

advantages of 1x1tb
higher performance-larger device tends to have best performance (1x1tb vs 1x500gb).
less sata sockets/case space used..more options later down road
cheaper - £/gb tends to go down as size goes up

advantages of 2x500gb
Backup of OS drive as drive rather than partition - dedicating an entire disk (rather than partition) to the os, makes OS backup/restore a little bit more fool proof for piece of mind..
Performance - in theory 2 drives utilised fully at same time faster than 1...but highly unlikely both drives would be fully utilised at same time...esp if 1 is os and 1 in games.

A 1TB SSD does not have any speed performance improvement over a 500GB SSD, pretty even stevens.

But i am starting to see sense after a lot more research, why buy two 500GB SSDs for raid 0 (to replace my 128GB SSD) when i can buy a 1TB SSD and have everything on the one drive.

For general PC use and gaming is raid 0 really relevant? Is raid 0 even relevant with SSD's? Or is it just pointless (would there be a performance boost)

Yes RAID 0 is relevant with SSD's and would give a performance boost, whether or not its useful to you for general PC use and gaming, only you can answer.

Yeah true, i think i leaning towards buying two 500GB SSDs as i can get them cheaper than buying one 1TB SSD. And if at some point i want to change from Raid 0 i can have one for my OS/games and another for storage.

I wouldn't touch RAID 0 SSDs with a bargepole, you're doubling your chance of failure for a performance increase you're unlikely to notice.

When people say double your chance of failure though it is only really an extra 1% chance, i have not had an SSD fail so far (touch wood).

Seems more taboo than anything.

An extra 1% chance? How do you work that out?

Was doing some research the past few days and tomshardware and techradar i think it was had some people doing mathematics etc, even though it would never be 100% accurate you could see the basic idea.

Ignore morons... they are clearly coming up with some crap to justify what they want to express.

Going from 1 drive to 2 drives... DOUBLES the chance of hardware failure. Literally.

Add in to the mix the chance of software raid failure, which does happen... a lot more than a dedicated controller (which motherboard onboard controller IS NOT) and that adds an extra layer of failure potential as you can't always just stick the drives on another board and rebuild.

Over the life of 3-5 years the failure rate of a particular drive may only be 1 in 100... make it two drives and the probability becomes 1 in 50.

I wouldn't know how to propose the chances of software raid failure... but if you lose one drive, or the raid corrupts - all data is gone... so make sure you have an active backup of what you want to keep.

I've raid drives fail and raid arrays corrupt... it's not fun if there's something on there you want to keep ;)

If it really is just a basic boot drive and game storage... then you won't lose anything critical at least... but don't kid yourself about failure potential.

Yeah i don't have anything important on any drives i own ever but if on the rare case i did i always put it on a USB stick as well. The only thing eating away at me is if i am spending £300ish on a SDD or x2 would it not make more sense to buy the Intel 750 series? I will also be upgrading my whole rig once skylake is upon us.
