My 1 TB NTFS formatted external SSD used exclusively to hold full blockchains from both mainnet and testnet has only ~ 367 GB left to be full , so probably in half of year I will think about acquiring new SSD drive with capacity of 2 TB.
No rush: you have about 3 years left before it's full.
yeah unless we go with a lot of ordinals but right now good ssd's are cheap.

My refurbed Asus linux laptop is happy with the 2tb crucial I got for only 85 bucks with tax.
It will last a while before it is filled.
