Waiting for 2T SSD's to become affordable, if they ever do.Depends on your definition of "affordable".
I bought 2 2TB NVMes at about 300€ each... But SSDs and NVMes have a quite "limited" life. Look at TBW numbers. Many SSDs and NVMes have some cache RAM for sectors that get rewritten very often, but backups tendo to be sequential so the cache is nearly useless. Once upon a time there were flash-backed ramdrives: controller + RAM + SSD + battery, all the flash contents fitted in the RAM, so the flash was never written unless the battery got discharged enough. Safe assumption: battery dicharging = host off = no ongoing writes. Needless to say the cost was really high and they where usually reserved for (parts of) databases.
