Yes, thank you. I didn't know that either.

@ A Guy:

I feel better now. Thanks.

You're quite welcome.

I only came back to the forum to get help with a keyboard problem, but I'll play this game while I am here. Two Samsung 256Gb Pro in raid0 for OS. Attached to SATA ports 0/1 on X79-UD5 with Intel Enterprise Driver. I have seen someone who got just over the 1Gb/s with this setup. I couldn't quite manage that, but what really impresses me is the 4K performance.

I just bought an Samsung EVO 120, I didn't install the software yet. I was going to buy a Samsung Pro but in my opinion the numbers between the two are almost identical, plus I saved $50 so I spent it on other PC hardware

I had got as far as ordering a pair of 250Gb EVO when I discovered that they don't work well in any raid configuration. In Fact Samsung specifically advise against raiding EVO drives. So I had a mad rush getting on to the supplier and changing the order to a pair of Pros.

I get all my hardware advice from the Adobe Premiere Pro Hardware forum, as they really know their stuff there. They didn't like that I wanted to put my OS on a raid0, but I do a lot more Photoshop than Premier Pro, so I went ahead anyway. This is the thread, and there is a link to another relevant thread

Adobe Community: How To Install OS on Raid0?

I think Peru Bob on the Adobe forum is right. Raid will not buy any significant performance advantage. The access time for Raid is the same as for a single unit and the OS performance is driven by the access time.

This is completely true. The only numbers of any importance to anyone using a single SSD or SSD + HDD setup are the Random 4K's(not 4K QD32/64) and access times. RAID 0 affects neither of them. Sequential read/writes will become important when you have multiple, large capacity SSD's and you transfer files between them. As of now, anyone using an SSD/HDD setup are limited to the speed of the HDD which is on average 100-150 MB/s versus 500-500 MB/s for an SSD.

Hi Kelly, long time no see.

I think Steve was going to RAID two SSDs to see what happens.

kbrady1979 · 03 Apr 2014

Hey Gary! Feels good to be active around here again. IF there are any measurable differences, the risks of RAID 0(to me) aren't worth it. I still don't think it will improve boot time, load time, or anything important. It will almost double your Sequential Read/Write speeds(which most of us can't take advantage of), and it will pump your Random 4K QD 32/64 up quite a bit. Most of us generally operate in the range of QD 1-7 or 8, so QD's of 32 or 64 don't mean much.

Kelly, I have done it in the past, just to see how it works, plus the fact I have always advised against it for the reasons you mentioned, but like to see for myself before advising anyone. It did not help and what you said is absolutely correct. I have, as Gary said, thought seriously about doing it again. The only advantage of Raid 0 is the increased space from combining 2 SSDs. Speed is not affected at all nor is access times. usable space is improved. That is the only advantage if you can live with the risks, which I can due to the fact I am a backup freak. I'm not concerned about losing anything. We are happy you are around more, you add much to these forums.
