Latest Word on SSD Trim?

[eric@psmnv.com]

I've been Googling all day and can't find the answer. Back in 2015 there was a big issue about data corruption on SSD drives due to incorrect handling of TRIM by the Linux kernel (https://blog.algolia.com/when-solid-sta ... hat-solid/). It is not clear if that was ever resolved. The issue was related to NCQ TRIM, which Linux does and other operating systems do not (Windows and OS X use sequential TRIM, whereas Linux uses queued TRIM). Does anyone know if SSD drives are safe to TRIM on Linux these days, or are Samsung drives still blacklisted?

Pretty sure the Samsung drives are still blacklisted for TRIM. That doesn't mean it doesn't work - fstrim -v here reported that it trimmed 17GB from my 32GB / filesystem on a Samsung SSD.
