RAID 0 SSDs?

Hey guys, I hope everyone is doing well. I have a question regarding some opinions on RAID 0 for SSDs. I have checked a lot of the topics regarding this but some are pretty old and don't take into account the advent of TLC NAND drives and how cheap they are now. I am also not new to SSDs as I own a Samsung 840 and Crucial MX100 respectively.

I am aware of the cons of RAID 0:
-More points of failure
-No gain in real world performance

Trust me, I would go for a PCI-E SSD straight up, but I have one full PCI-E lane on my Z68.

Some one talk me out of it/recommend good drives. I'm thinking of the OCZ Trion 150 240GB. I have worked with the ARC 100 and Trion 100 they are great for the price. Not top not notch like my Samsung but good. I'm really just looking for the next bump up in performance as we all are.

Thanks for any help!

Hello,

Something i have looked into as well, although since accessibility is so fast on ssd already i am guessing the "Bottleneck" would be in the sata interface not really being optimized for SSDs, moreover i don’t think a full 16x lane is required for PCIe SSD,
For example the "Kingston HyperX Predator HHHL SHPM2280P2H 240GB".

Pehaps that is something looking in to :)
Best of luck!

Well, the problem is I don't have a lane that is physically bigger than 1x that isn't populated already by my graphics card. That is the exact SSD I would go with if I could.

Aha! that's a pity, I guess it comes down to personal preference if the performance gain from a raid 0 SSD solution is worth it, I don't have any proof to support my own take on this but I would not go for a raid setup with SSDs. although i have done some searching and have not found anything spectacular about it so i wouldn't. But if you do i am very interested to see some benchmarks! :) Although if uptime is of the essence i would go for a RAID1 for example in a critical storage system.

Good Luck!

Isn't worth it

save for an X99 system or 4k display instead.

Riad 0 SSDs work fairly well if you are doing very large complex work loads. Outside of that, it is worthless.

I would tell you to get a cheap single SSD, and sell your mobo and CPU and move to a cheap skylake setup. You will be much better off.

I have no complaints about my 2500K. Don't see how X99 gives me more storage performance though.

So general consensus is to go with one?

Riiiight but raw read and write speeds are like 1/100th of what makes up storage speeds and system performance.

You still have to consider system latency and how each new generation handles system calls and so forth and so on.

I have 3x Kingston 120GB SSDNow 300 drives in my system

All are in AHCI. The first drive runs the OS. The other two are software striped in Windows.

The striped array churns out ~850MB/s seq read, and ~300MB/s seq write. The single drive is almost exactly half that.

In reality, I cannot tell any difference running apps and games off either the single drive or the striped volume. They are both very fast for typical desktop use.

I'm sure I could get better write speeds if I looked into it, but for what I do its really all about the read speeds.
