Can you Raid 0 two HDDs With Optane and see speed increase?

[paldar]

I am going to assume it wound't do anything (if its even possible to do it) because the Optane it is going to keep the CPU fed.

no

Since the raid array acts as a single drive, the optane would accelerate it.

i wouldnt see why not, but i also wouldnt see the purpose.

I am wondering what the diminishing return would be like on it and if it would be even noticeable.

The only diminishing return is that it can only cache 16gb/32gb of your large amount of storage.

Ya but if it needs to call for some fresh files would you notice a difference.

Not entirely sure

Well... Since Intel Optane is nothing else but a fast cache for your HDDs, you can put as many HDDs in RAID as you want, I guess.

Guess not. Since you access file for the first time, there is no way Optane would upload it to cache. But after next few times it might be faster (depends on many things).

Since the Optane can already work as a cache drive to complement HDD and greatly increase speeds I would see the RAID 0 as a much more inferior solution.

Running Optane and Raid 0 at the same time not separately. the question is when the optane calls the hard drives would you still notice a difference.

can't be done. At least not yet

Intel Optane memory cannot accelerate a RAID volume. An Intel Optane memory volume can reside in the same system as a RAID volume. The operating system must be on the SATA drive accelerated by Intel Optane memory.

you cannot add it as a drive. Its just a cache drive built on proprietary technology. there is a optane ssd coming. Even then if you put a SSD in raid with a mechanical drive you would be handicapped by the slower drive. I have actually tried it with both RAID1 and 0 when I last benchmarked newly purchased drives. because the mechanical drive holds half the data, half the data can only be accessed by the speed of that mechanical drive. You effectively get the same as what you would have gotten if your RAIDed 2X mechanical drives.
