That depends on how you define “decent” , and your use case.

Be careful that these are QLC drives.  QLC is pretty new and longevity would seem to vary quite a bit based on op mix.  These might be fine for read-mostly workloads, but high-turnover databases might burn them up fast, especially as they fill up.
