Question from Art: Asked on 16/11/2025 is it really 16TB? Official Seagate website only states 1 and 2 TB options

Question from Deejay MikeyTee: Asked on 14/11/2025 Good Morning,
Is this drive actually 16TB storage, because this is what I've been looking for, for my other hard drive backups, this would be fantastic and help me greatly
Best regards
MikeyTee
Hi Deejay,The Seagate Ultra Compact External SSD with model STMX1000400 is 1?TB, not 16?TB, so it won’t provide the amount of storage you’re looking for to back up your other drives.Thanks!
