RAID 0 Terribly Slow Performance.

Hello, I keep having R/W speed issues with my OWC ThunderBay 8 (TB3). I have 8x 8TB Seagate EXOS drives with 250/mbps sequential data rates RAID 0 which should give me outstanding performance. Of the 64TB I still have 20TB free.

I should be getting close to 2000/mbps but im am only getting 600W and 400R speeds!

 

(Yes I have everything backed up to the archive server and this is the active project drive filled with mostly video and photo files)

 

I understand I won't always have 2000r/w but this amount is so bad it makes me want to cry. Please help.

Try AJA System Test for more consistency

5K video resolution

RGBA codec

16 or 64GBfile size.

 

Do two tests, standard, then in settings disable "use file system" and see if there is a huge difference.

Also you can click the graph button when you have results and see if there are major dropouts in the test.

Attached is a screenshot of the test. I also attached a Softraid Report.

While you won't get 2000MB/s, you should at least get 1200-1400. I put together a hodge podge of older drives and got this.

@softraid-support yea definitely not 2000, but anything above 1100 I’d be fine with. Just so frustrating having spent so much time and money and still constantly disappointed with performance 😭

Also, disable Spotlight, to test if that is causing anything.

 Your performance is too low, something is going on.
