Question Synology RAID Calculator | RAID0 mixed disk capacity

[Telos]

Looking to redo my backup NAS as I'm running out of capacity. I have 10TB and 6TB disks which I was going to join in a simple JBOD.

Using the Synology RAID Calculator I noticed that in a RAID0 configuration,

Capacity = 10TB + 6TB = 16TB

I always understood that RAID0 mixed disks yielded ...

Capacity = (number of disks) * (smallest disk)

Does Synology do this differently ( a la SHR), or is their RAID calculator borked?

RAID0 will be faster then jbod but both will combine their capacities

RAID0 will be faster then jbod but both will combine their capacities

Thanks. My preference is RAID0, now that you've confirmed capacity.

My old Lenovo ix2 NAS [still not dying] is set up with a mismatched 2TB and 1TB. It's doing non-critical Time Machine backups, and radiating heat.

Since the options were RAID1 / RAID 0 / None, I'm guessing 'None' is JBOD as it stores data contiguously vs RAID 0's striping. I don't care either way but I think I opted for JBOD because the disks aren't the same at all and most of the time it will be writing to one disk not both.

Of course, Rusty was right... Synology's RAID0 does indeed yield the sum of disk sizes, even when those disks differ in storage capacities.
