I've got disks spinning around for more than 10 years before yours had |

started. One has been showing similar errors for almost half its life. |

I can't advise on a replacement, other than say check if any candidate uses |
20 |
Shingled Magnetic Recording (SMR) technology and avoid it unless your use case |
21 |
involves writing rarely, reading often. Conventional drives use Perpendicular |
22 |
Magnetic Recording and will not suffer from the performance degradation of |
23 |
SMRs when written to frequently and extensively. |

You'll be able to replace your spinning SATA with an SSD SATA using AHCI over |
30 |
the same port. You won't be able to get an M.2 NVMe (M-key socket 3) doing |
31 |
its magic without a PCIe 3.0x4 port on your MoBo. |
32 |
|
33 |
Sadly my hardware is too old and it won't boot using NVMe. |

This value is worth considering further. Start with a backup of your data, |
74 |
but do not overwrite your older backups. |
75 |
|
76 |
Then consider zeroing the defective sectors. |

With 1456 pending sectors you'll be there for a while. Alternatively ditch it |
82 |
and get a new drive as you intend to do anyway. |
