Problem with TRIM on SSDs

[cucker tarlson]

Serious write slowdowns only happen when you hit the SLC buffer hard (as native write speeds are pretty weak with tlc or qlc flash nowadays). Just removing trim won't kill write performance tenfold. You might lose 10-20% (highly depends on firmware and flash controller) but not anything serious to be noticeable.

well if you hit the buffer then you'll lose much more than 20% on some drives.

Yes, write speed can drop to 5400rpm hdd levels, but that's an entirely separate issue, not related to trim.
