4 TB upgrade kit

The 4 TB upgrade kit is a 4 TB drive, ready to use, that replaces the 2 TB drive in an older AVADO.

Replaces the 2 TB drive of an older AVADO with a 4 TB SSD: 4 TB is the minimum an Ethereum validator needs today, according to the EthStaker hardware guide
The drive comes with the AVADO operating system installed, so there is no software to install by hand
Installing it takes a screwdriver: open the box and swap the old drive for the new one
The new drive starts fresh: back up your mnemonic or validator keystores before you swap, then reinstall your clients from the DappStore and let them sync
Keep the old drive out of the box once the new one runs, so the same validator keys never run twice

Not sure which model you need? Ethereum staking hardware requirements in 2026 explains what a validator needs and how the models compare, and Ethereum staking with AVADO shows how setup works.
