This question may appear duplicate of this Bad block count (early – later)? but here I do not have early or later separation of data so this is not an exact duplicate as such and I have a larger scope.
I have Adata su650 480GB SSD which is generally working fine. Recent check of SMART values using crystaldiskinfo reports 257 bad block count. Now I need to know a few things with respect to this parameter
- What is this bad block count and is it early or later bad blocks?
- Does it mean 257 blocks are bad?
- Are they excluded from I/O after being reported?
- Sometimes when copying a single large file, the speed drops to just 2 – 3 MB/s for a few seconds and then again jumps to 200 MB/s. Is this because of bad blocks?
- There’s no visible data loss as of now. Nothing seems to have gone corrupted
- Do I have a bad SSD?
