I have just installed brand new SSD into my laptop, and I see smartctl -a /dev/sda is showing errors already

Specifically, these attributes show non-zero:

Raw_Read_Error_Rate
ECC_Uncorr_Error_Count
Unc_Soft_Read_Err_Rate
Soft_ECC_Correct_Rate

Does it mean my SSD is already failing ?

  • Please: a) Run sudo lshw | grep product | head -n1 && sudo dmidecode -s bios-release-date && sudo dmidecode -s baseboard-product-name && sudo dmidecode -s baseboard-manufacturer b) Add that plus the make and model of the SSD into your question by clicking edit. Please don't do Add Comment, just click edit and enhance the question instead. – K7AAY Jul 9 '19 at 18:47

SMART values with the TYPE=Pre-fail or FLAG=13h or 33h are what to watch out for. None of those values you are concerned with are in those categories. Backblaze reports item 187, "Reported Uncorrect/Reported_Uncorrectible_Errors" shows as 0, which is good. Here's a more thorough article on the subject of using smartctl to monitor SSD health.

But, worried about your system? Get another SSD of about the same capacity (an M.2, mSATA or mounted in a DVD replacement carrier in a laptop) and configure RAID 1, because as the article on smartctl noted, 32% of SSD failures occur with no warning from SMART.

M.2 will deliver the same speed in general as an SSD in the SSD bay; using an mSATA or putting a 2.5" drive in a DVD replacement carrier limits you to SATA2.
