Black Friday deals bring about RAID expansions, hand me down drives lead to more expansions. The 4TBs i pulled out of service had almost 6 years on them. Still passed SMART!
This is actually my first go at using this little trick. I only noticed it a few years ago. i haven’t had a need to use it. Until now. i am so delighted that Synology continues to innovate. Every time i deploy a Synology, it has even more functionality. i am not getting paid for this, honest endorsement. I only wish they made direct attached storage or SANs. I do not mean to imply that i have a problem with NAS.
I am not only upgrading the capacity, but the throughput and seek times as well. With dual drive protection, it will be a few redundancy passes before i see any additional storage and probably even longer before i will see much more performance. it will be an interesting project. The process so far has been simple. i just deactivated the outgoing drive and replaced it with the new bigger faster drive. Once that is done, you repair the volume with the new disk and wait. And wait. Eventually do it all again. And again.
