# Intel SSD or other brands - From: Adam Goryachev \ - Date: 2016-12-29 01:52:10 - List: linux-raid - Page: https://ratatoskr.run/linux-raid/2016/12/6634027 - Thread: https://ratatoskr.run/linux-raid/2016/12/6634027/t.md ```text Hi all, I've spent a number of years trying to build up a nice RAID array for my SAN, but I seem to be slowly solving one bottle neck only to find another one. Right now, I've identified the underlying SSD's as being a major factor in that performance issue. I started with 5 x 480GB Intel 520s SSD's in a RAID5 array, and this performed really well. I added 1 x 480GB 530s SSD I added 2 x 480GB 530s SSD I now found out that performance of a 520s SSD is around 180 times faster than a 530s SSD. -- Adam Goryachev Website Managers P: +61 2 8304 0000 adam@websitemanagers.com.au F: +61 2 8304 0001 www.websitemanagers.com.au ```
