Yeah that's what I figured... I'm getting 560 Read and 528 Write speeds...

The read / write will be lower than doing a hardware raid as you have the software over hang.
You also have the sata limitation. All the sata ports share a single connection.
If you unraid the drives then you will lose all the data stored on those drives.
Raid 0 has never and will never give a 2x performance gain. .50 - .75% should be your pencil mark.
Raid 1 will give more of a performance gain, but you will lose 500GB, and not all controllers will give that performance increase. Lower end ones will totally ignore the second drive and will only write to it in spare time. Others will read and write to the drive that is not being accessed at the time and others will read and write to both. Motherboards normally ignore the second drive.

Hi all,

 

I recently tried doing a raid 0 with two 500gb SSD's, however when I checked the final result I now have 1Tb instead of 500GB.

 

To further dive into my investigation I did a HDD benchmark and I get around 550 Mb/s which is what a stock SSD does.

 

Is this normal? If not how to I undo my raid if I used the disk management software in Windows 10 pro?

 

Kindest regards,

 

M-P

That's what should happen

That's strange for sure.

I haven't used it before so I can't say. You could just wipe the drives.

You sure you set disk management to striped not spanned, spanned would explain the speed.

 

You can just delete the logical volume if you want.

I would also recommend running the benchmark on just one SSD while not in RAID, if you are going off the advertised read/write numbers, they can be a bit off in real world use. Just my 2c.

Really? I thought basiaclly if you do Raid 0 you'd still get 500 GB but close to double the speed.

Pretty sure, I followed a tutorial for Raid 0 and chose striped, but if I didn't is there any way to revert and go with spanned? I've never done Raid before and didn't take into consideration the "what if?" in the case that i wanted to revert...

I checked them before and they were both around 540-560 Mb/s

 

These are 2 Samsung 860 Evo's so they should be pretty comparable speed wise.

because in raid 0 both drives are sharing the data, so you might want backup your data within windows before you break the raid within the raid bios. but before you do that, have you updated all of your bios, drivers, firmware?

Everything up to date, the drives are in Raid 0 for game files. I doubt there is an issue if I were able to change the raid type somehow..

RAID0 alternates data between the two drives so the drives basically get combined. If you did RAID1 it would duplicate the drives so you'd only get 500gb but speeds should still be doubled.

What you have right now is normal except that for some reason performance isn't quite as high as it should be.

It's not a race to the bottom.
