 |
|
Hi guys, my laptop has a hybrid hard drive with 250GB SSD NVMe + 1TB HDD (it's Asus ASUS FX503VD-E4022 ). Since the hard died two weeks ago and I'm now with the new one, I want to take a better care of it.
So my question is: How do you fstrim a hybrid hard? Because I get:
| Code: | sudo fstrim / -v
fstrim: /: the discard operation is not supported
|
and also
| Code: | | sudo hdparm -I /dev/sda | grep "TRIM supported" |
But the hard is hybrid, so probably it needs trimming? So any ideas? Or any other ideas how to extend its life (already checked it with smartctl with a short and long test, all seems fine)
P.S. Still using Sabayon, so I'm posting it in the Unsupported software. |

denijane,
It depends how you use the drive.
If you use it as a single 1TB hybrid HDD, the SSD is used an a cache. Its not yours to control separately.
If you use it as two drives, you may be able to trim the SSD, if the SSD supports trim.

Hi NeddySeagoon,
well I'm not sure how the SSD is used, but it seems to me that it's used for cache, because you can't see it as a separate device in $fdisk -l .
Do you have an idea how to figure out how it used and anyway, how to extend its life? |

denijane,
Modern SSDs have very good life expectancies even with very hard use.
I wouldn't worry about it.
Even with Gentoo, where you build everything from source code, SSD life is no longer an issue.
