[kwlug-disc] SMART for SSDs

[Khalid Baheyeldin]

So, I had an SSD lying around for a couple of years (long story, bought to
benchmark against spinning rust disks for a client project). My laptop disk
died 1.5 months ago, and when checking SMART values for it, it was not good.

Therefore, I decided to put the SSD drive in the laptop, and copy the
spinning drive to it. I blogged on the details of how to do that separately.

When I run SMART on the SSD drives (smartctl --all /dev/sda), I get the
following table:

For those who have been using SSDs for a while, my question is: should I be
worried about lines with ID 1 and 233?

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