If you use Gentoo and have an adequate amount of RAM I suggest that you create a tmpfs for your portage TMPDIR to reduce the writes to your SSD!https://wiki.gentoo.org/wiki/Portage_TMPDIR_on_tmpfs

@Ghosty is it true that the translation layer in some SSD have a write limit? Similar to how DVD+RW had a limit to rewrites?

@nergal I never heard about that. But it is imaginable because of the limited lifetime of nand flash. Maybe some cheaper SSDs do that :thinkhappy: But in general it is best practice to not write a lot of temporary "garbage" data onto a SSD :D

@nergal I believe that the nand cells it self have a hard write limit to prevent data loss. But don't quote me on that ;). I am not an SSD expert

@Ghosty if so why promote SSD as sturdy primary and secondary storage option? The only downside to rotational is speed, then?

@nergal It’s not like SSDs die really quick. Under normal circumstances they will also have a long lifetime. Which makes them a valid option for using it as an operating system drive. And they are also shock and vibration resistent which makes them perfect for laptops. The one thing that shouldn’t be don’t is using an SSD as a backup drive or as an archival drive. There you are better off choosing a HDD.

@Ghosty would be great if there was a movement to translate old platters to new boards.

@nergal It would! But since every manufacturer and almost every model (**revision**) of an HDD has slight differences in how data is written to the platter it’s basically impossible :(

@Ghosty the platter is not a plain metal disk then? The cylinders are set to specific arms?

@nergal Yep. But the way data is organized on the platter can be different as far as I know :).

@Ghosty I bet that is not so. The arms calibrate. We had to do that back in PATA/IDE days. CHS and LBA alignment. https://www.thomas-krenn.com/en/wiki/CHS_and_LBA_Hard_Disk_Addresses

@nergal Mhh. Interesting! I watched a few videos about board replacements of HDDs and in every single one of them it was said that you need an donor HDD that has the exact same board(-revision) for it to work :)

@Ghosty that is for board transplant. The whole mechanic is part of trade secret for the HDD manufacturer. The platter is not. I conject the platters are almost the same in all of them.

@nergal This would be interesting to find out!
