So I have this NVME drive 

https://www.newegg.com/Product/Product.aspx?Item=N82E16820326151

 

and I order a second along with this 16x slot adapter 

https://www.newegg.com/Product/Product.aspx?Item=9SIA6V883F4023 

 

I have one extra pci 16x 3.0 slot on my board, using it will drop my gpu so both lanes run at pci 8x 3.0 speeds, so pci 2.0 16x each 

 

I am looking to use Raid 0 with both NVME drives to boot into windows, should I expect to see double the bandwidth? double the speeds?

You'll see double the storage and that's about it. Unless you've got a 10Gbit network connection and are moving tons of files back and forth all the time you'll see almost no real world benefit from running two NVMe drives in RAID 0

IIRC RAID 0 will provide you better WRITING speeds, but not READING speeds, you should use RAID 1 to increase the reading speeds but with a NVMe it's a waste of money IMO

you should have picked a Samsung 970 Evo, better speeds and a cheaper and safer solution

Edit: it improves both writing+reading, thanks

raid 0 will speed up both reads and writes.

RAID 0 improves both. I think RAID 1 *might* be able to speed up reads as well but it's meant to protect data, not speed up its access.

IMO...get a larger single drive. To stripe NVMe drives, you would need to arrange the drives to be on the CPU lanes to have any sort of benefit and even then there is no guarantee of noticeable benefit.

okay i went with these because they are cheap and when i maxed the settings on newegg, it showed these drives. plus HP has to make a lasting product. Raid 0 is for faster read/write, raid 1 is 1to1 backup. I got two smaller drives (boot/programs) and have a 3tb steam drive.

NVMe RAID 0 is pointless. Seriously pointless. Don't waste your money on two underpar EX900s. If you are going to spend $60, just get one good EX920: https://www.newegg.com/Product/Product.aspx?Item=N82E16820326777&ignorebbr=1

ive seen a few different systems with NVME raid 0 and the before and after speeds say other wise... the specs say it should transfer much faster... I have the bandwidth for both drives.. the second nvme drive is running in an 8x pcix 3.0 slot = pci 2.0 16x bandwidth..

But why?... I don't feel a difference after switching from a SATA SSD to a Corsair MP510... Let alone two NVMe drives in RAID 0... For what purpose do you need so much throughput?
