Re-Allocated sector count, what does it mean?

I've Google this but all I find is gibberish and people arguing over what it means blah blah blab.......

Drive in Question is an Intel SSD 330 180GB

According to SSD Toolbox Re-Allocated sector count is RAW = 3 Normalized = 100 Threshold = 0

I suspect this is saying there are 3 bad sectors on this drive but I'd like to know for sure.

TIA
 
There were 3 total bad sectors that were remapped sometime in the past to good sectors.
 
Just to ask, what's the Wear Leveling Count (attribute B1) showing on that drive? For SSDs, they generally start at 100 and the counter counts down and gives you an idea of the overall usage at any given time. For example I have an OEM model of the Samsung 830 series SSD (Dell OEM model) and right now my B1 attribute shows 89 and that's because I have 13.1TB of writes to the drive (I got it used, when I got it earlier this year in a used laptop it had 3.6TB of writes on it) so I should be good to go for some time.

But I'm curious to know what the B1 attribute shows for that Intel SSD and maybe even the total writes so far on it - you can use a tool like CrystalDiskInfo to get the info in one simple interface meaning you don't have to convert the LBA counts to actual gigabytes as it does that for you.
 
Intel SSD Toolbox doesn't list a B1 attribute but it does list a E9 Media wearout indicator

Seems every manufacturer likes doing it different but I would presume it's basically the same idea: starts at 100 and then winds down from there. Looks like about 54TB written by attribute F9 and then it says 190TB with attribute E1 (which is supposed to measure LBAs which aren't directly equivalent to gigabytes) but then again I'm not sure any of that info is trustworthy to be honest: 923,915 hours powered on would mean the drive is 105 years old and it's only been powered off and on 74 times, that's some serious uptime going on. :D
 
It's definitely wonky. I've never had any problems with it in the 3 years I've owned it. Guess I won't worry about it until I do. It's in a 24/7 media server so not mission critical.
