Swap, SSD and Debian Linux?

Question

linux

I want to put on my Thinkpad x230i instead of the usual 500GB disk - an SSD of a similar size
I looked at various tips on keeping an SSD under linux, for example: https://sites.google.com/site/easylinuxtipsproject/ssd
In connection with this, a few questions:
1. How to partition a disk? Should I leave 10% of everything unallocated, or should I keep 10% free on each partition? Or you can stop worrying anymore, because some even write that disks are sold at 480 GB, and not at 500, because the rest of them are just reserved for these purposes.
2. An important purpose of buying an SSD for me is a fast swap. So that the computer quickly exits sleep mode and so on. The tips say "turn on sleep mode - Khan disk." Is this still true? Is swap partition generally bad for SSD?
3. As I understand it, I have SATA2 in my laptop, and the disk will be SATA3. Will this cause any problems other than some slowdown?

Answer 1

You don't need to reserve anything.
Don't sweat it.
1. You will not be able to reserve so that it will be used automatically. This will make the disk itself. He does not give you more than he has reserved. You just don't see reserves from the outside.
2. There are invisible reserves in both HDD and SSD in general.
3. This is not the reason for the difference in disk sizes.
4. SSDs are being killed, yes. But not in one day. I have been working in the most intensive modes for 5 years now. Do not be afraid. You buy it for your comfort, and not for the drive to live forever. If you are afraid - take an expensive server (corporate version). But, in my opinion, it's easier to just replace it with another one after 4 years. They are certainly not cheap. But once every 4 years you can afford it.
