More storage
Using a ReadyNAS 2100 v2. Got 4x 1TB HDD running RAID 5. Im totally new to this NAS and RAID stuff. Can I just swap out one of the HDD to a bigger one? Will I loose data? Currently using about 7...
You cannot replace two at the same time,. You would need to swap out one, wait for the RAID to re-sync, the swap another and wait for a re-sync and then the expansion.
Frankly, other than to test out the NAS, using 1TB drives was probably a bad idea. IMHO, your best bet is to start over. Back up your data and start over with two drives in XRAID where each one is at least big enough for your current needs. That will give you a RAID1 the size of one of the drives. But when you need more space, you just insert one more of the same size and it changes to RAID5, expanding by the size of the drive. Then you still have an empty slot to do the same again when you need more. In today's market, I wouldn't start with anything less than 8TB drives.
Thank you for your reply.
Have Changed to X-RAID now.
So for more storage I will need x2 HDD? Also how would I know which ones In the NAS I can pull and not loose data? Or will I have to create a backup of all my data? And re-copy it all back once new drives are installed?

- Thanks for that.
Sounds like I need to buy 4TB usb drive to backup all the data then before I start expanding the NAS.
Unless a cheap ReadyNAS 2100 comes up on eBay again, only paid £60 for mine with the 4 1TB drives. Since you should always have a backup, you may want to get a larger USB drive so you can keep that backup current. RAID is not enough to protect your data, you need real backup (which means on a separate device, the cloud, etc.).
- Ah yes! Very good point that.
