I have a Synology DS1621xs+ and want to understand the performance differences on DSM 7 for RAID/cha choices/
Have a 10G network, 24GB RAM, and two empty M.2 slots for cache.
I don't need much space (8TB) but I do want a larger array to improve performance. The lowest cost would be a RAID 1 with two 8TB but that is the slowest option?
RAID five is fastest solution? but how much performance gain do you get as you add drives?
Also limited to drives that Synology allows with specific firmware is hard to find a newer drive that matches. the best cost drive I can find is an Exos X16 16TB Seagate Recertified $150 with a 2-year warranty. But wanting a fast array , the smallest I would have three disks or 32TB which is 4 times the space I need. 5 2TB drives are more $ than the 3 16TB.
Isn't it bad on RAM and Cache requirements to have tons of free space? Or can you just not assign part of the space?
I usually overthink everything. Please help with a solution for this platform.
