Which raid feature is right for me?

nightrider1470 · 28 Sep 2013 at 13:02

I have decided to buy this raid box controller for 6 of my large hard drives with room to add 2 more in the future.

4 of my drives are installed in a 4 bay drobo at the minute and 2 are in external caddies.

Am really worried that pulling them out of the drobo and throwing them all this device I might some how loose some data?

Am unsure as well what raid setting is best for me to use? My data is 80% blueray movies and 20% important camcorder footage

Can anyone shed some light on what best raid setting is best to use and if it might mess or loose with my data on the drives?

Thanks!

RAID is not a backup solution, so based on that choose RAID5 and implement a proper backup of important data.

RAID 5 will give you the best balance between performance and resilience with the ability to lose a single drive without losing data. Write performance will be impacted though compared to RAID 0+1.

If you set up a new raid set with your current drives they will be wiped so you'll need to find somewhere to put your data while you migrate it.

Ok raid 5 it is

Can I just ask, can I keep adding empty drives with raid 5 and it will auto add more space?........ I have 6 drives at the minute but as I add more data I will want to add more drives when space is running low

Thanks!

To reiterate Rilot as I'm not sure you read it - if you move your drives from the Drobo to the new box, all your data will be gone. Definitely gone.

It could add more drives automatically, but only if the product is well set up. I don't recognise the product in the OP and you haven't said what it is, so there's not much chance of one of us reading the product specification for you.

I use raid 1. Disks are cheap enough and Raid 5 isn't brilliant in terms of failure modes.

Just a question have you considered a device from Synolgy there SHR technology is very good and much more efficient than RAID 5.

Check out the calculator below.
