Asustor AS4004T is kinda awesome n quiet. Look it up! SSDs for life, man.

TBH any NAS will make some noise, the drives themselves ain’t silent. But if noise drives u crazy, don't skimp on the NAS—get something quality. Also, SSDs are quieter than HDDs, so maybe consider that for at least the system drive?

One word: TerraMaster. Specifically the F2-220. It has a sleep mode that makes it super quiet when not in use, which is great for a bedroom setting. Plus, you can schedule it to run intense tasks when you're not sleeping.

lol just turn on some white noise and call it a day. NAS fans are like lullabies for geeks.

Silence is golden, especially in the bedroom. If you want it dead quiet, consider a fanless design or a QNAP HS-453DX. If not, anything with larger, quality fans that run at a lower RPM will generally be quieter. Replacing stock fans with high-quality aftermarket ones like Noctua can also make a substantial difference.

just built my first NAS with some Noctua fans and they’re silent af, might wanna check those out when building or modifying ur NAS

For a bedroom, I'd suggest looking at Synology's DiskStation models, something like the DS218+. Those are designed to be pretty quiet - and they're easy to set up for a NAS newbie.
