Huh they work great for me. Which Ladda did you get? I think there was some brown or like yellow ones or something that were made in china and weren’t quite as good I think. Also the LADDA 1900 will have a longer lifetime than the LADDA 2450s. In the same way that Eneloop Pro have fewer recharge cycles than the normal Eneloops.
Modern relational databases have support for it too including indexes etc. For example postgres.
