two nvme in raid 0

[Coolday]

two nvme in raid 0 will double the speed ? for example if one is 4000 MB/s both in raid 0 will be 8000 mb/s ?

UP TO....Double.

Never constant.

 

Has RISKS.

Raid0 is silly for Consumers when Apps and Games are SUPER responsive on a single one.

 

Hardly to zero benefit with NVME speeds so fast...

Vs 2 HDDs in Raid0 where speed was already limited..

Depends on the motherboard configuration. Two NVMe on a Z390? No - limited by chipset. On a X470? No - chipset is 2.0. X570 or using CPU lanes? Also no, but you'll get closer. There's diminishing returns as you add drives.

so no change in actual performance in apps and games ?

I have MSI B450 I can do raid with CPU lanes.

Not even for one nvme over sata6.   Nvme only might maybe help.  Later.  IF the console gaming market does certain things.  A few apps 1 nvme can help now.  Requires use of very large files. Like video editing.

Depends on the specific board, generally though the GPU will run at x8 if so (which isn't a huge deal).

RAID 0 slows down 4KQ1T1 speed which is what you feel on an OS drive.

 

NVME RAID 0 is really only good if you are moving massive files around a lot.

 

For example if you were moving ISOs and blu-ray rips around within the array or between arrays NVMe RAID will be noticeable faster.

Other than that, its really only good for making very large drives. For example you could RAID 4 4TB NVMe drives to make a 16TB volume. That is a hell of a lot of data at risk from RAID 0 though so you had better have good backups.


Unfortunately Optane has crappy price, form factors and capacity otherwise a 905P Optane drive would get you better OS load and app launch speed due to its crazy fast 4KQ1T1 performance. For professional use cases you can justify them but for a gamer, spend your $ on GPU and CPU.
