A SID just stands for "Security Identifier"... the non-user-friendly name that Windows uses to reference.
Have you specified to not use the recycle bin? Whether it's on an SSD, spinning disk, or USB flash, Windows will default to using a Recycle Bin. The use of a recycle bin is not necessarily life-time threatening to an SSD, so it's not disabled by default.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
