I am getting ready to buy a DX4000, but have some questions:
Are all the units the same - just different drive configuration? Or do they have 2-drive bay only and 4-drive bay units too?
If I buy the 4TB and it comes with RAID1, I’m really only getting 2TB of actual storage space. So if I buy the 16TB unit, I’m really only getting 8TB of space. True?
Not that I’d do this, but can I change to RAID 0 ever?
Let’s say I buy the 4TB 2x2TB) - later on, an I hot-swap drives out to add 2x3TB or 2x4TB drives? And if my unit is a 4-bay model, can I do the same?
all boxes are 4 bays and you use one drive for “redundancy”
You can purchase with 2 or 4 drives
2 drives is raid 1. 3 or 4 drives is raid 5
So you purchase a 4tb box, you have 2 useable. add one 2tb drive, it automagicly converts to raid 5 and you have 4tb useable. If you remove that 3rd drive it does not go back to raid 1, it will keep running and complain a drive is missing.
You must purchace “special” drives to add to the box
