Raid 0 with two SSD's (Low Write speeds)

[Nikokas5]

I have 2 ssd's http://www.newegg.com/Product/Product.aspx?Item=N82E16820226370

I recently put them into raid 0 and installed windows 10 on them and i get really low write speed compared to read speed which are normal!

If there is an explanation please let me know! Thank you in advance 😀

Because it has a benefit for servers or people doing large data scrubbing or compiling. You're absolutely right, 2x256GB RAID0 is generally worse than 512GB RAID0 for probably 90% or more of this forum's userbase.

RAID0 can still improve performance.

Which is what we've been saying all along.

Fair-- but I felt like RAID was being brushed under the table like some forbidden thing that shouldn't be done. There's nothing wrong with buying a second drive to supplement the one you have rather than buying a larger drive.

Well it was a nice solution for me who needed more space and why not getting some boost on speed even if i wont feel any difference? I like the numbers of ATTO! Crystal disk is letting me down 😀

And you can buy a second drive, hook it up, and have exactly the same drive space, without bothering about the RAID 0.

But, whatever.

So..OP..it is or is it not actually 'faster'? You initially said "really low write speed" in your first comment.

I prefer to have everything on one drive, and some applications do run into problems if they're not installed on the same drive as the OS.

As it seems read speed has been doubled in both benchmarks and crystal disk shows really low read speeds compared to ATTO which i run after i posted this! Maybe there is a defference at the way those two benchmark test the speeds!

It's also absurd to suggest that there's no benefit to RAID0 for SSDs. I'd take a larger capacity any day, sure, and the real-world performance is relatively unchanged, I'll agree; but the fastest speeds possible are only achievable by RAID.

Two OCZ Drives in RAID performing over 1,400,000 4k IOPS:

2 x 120GB SSD + RAID 0 = 240GB
2 x 120GB SSD with no RAID 0 = 240GB
Your only real benefit is a single drive letter, vs a C and D drive.

Personally, real world performance is what counts for me, because I live in the real world.
For some certain edge cases? Sure...RAID 0 can be a HUGE benefit. For instance, writing a large video file from 1 RAID 0 array to another RAID 0 array.

Since few people have that requirement or setup...and if it doesn't improve performance for what the vast majority of people may use it for....why bother?

sorry for necroposting, but for me worked like a charm, I had to make the raid because my design software cant be fully installed on another drive that inst windows drive, so i was stuck with 120gb drive, bought another 120 gb make the raid, and problem solved.
