SSD and Reallocated_Sector_Ct: how to interpret correctly?

Question

Iron

I'm a little versed in monitoring disks using smart, but now I'm faced with a question to which I don't know the answer and I couldn't find an unambiguous solution.
There is an INTEL SSDSA2M160G2GC disk
. Smartctl shows the following:

Vendor Specific SMART Attributes with Thresholds:
ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE

I'm interested in the parameter "5 Reallocated_Sector_Ct".
Value has not decreased, more tresh, raw value is 5.
With respect to hdd, this is not very good, but there is no particular problem either. The disk has reported reallocates, internal algorithms do not consider this value critical. I would not change such a disk momentarily.
But how to correctly interpret this in the context of ssd?

Answer 1

The whole reason is that it's an ssd. At the most is ssd and with smart it gives out this! that seems to need to be changed nafig, but everything works fine. Reallocated_Sector_ct is the discovery of your real sectors on the disk. But since this ssd gives out as if everything is very bad. How do I know you're okay with him? If so, then everything is fine. Download the SSD Life program, it will show exactly what condition your ssd is in
