CS-WX0BA HD question
« on: May 21, 2019, 07:45:57 pm »
I bought this some time ago... I guess it's been 7-8 years now... and one of the HDs has failed. I configured in a RAID 2 mirror, so my data is intact, but I need a replacement drive. The drive I pulled is 5400, but can the Cloudstor accept a 7200 replacement drive? Do I need to upgrade the healthy drive to a 7200 also? Or am I stuck with 5400? Bothe drives are/were 2TB. What happens if I upgrade to 4TB each drive? Thanks!

I assume you mean RAID1.

It shouldn’t have a problem with different drives with different speeds, but writes would be limited to the speed of the slowest drive. Keep in mind the 7200rpm drives probably generate more heat.

2x4tb drives should work fine but you’ll want to backup your data and create a new array with them. If you mirror a 2tb drive to a 4tb drive you end up with a 2tb array, if you replace the other 2tb you end up with a 2tb array mirrored across 2 4tb drives.
