When I saw 256GBs, I was like, I doubt that. If the mobo cost a lot more, maybe. This price point, given the ridiculous price of other boards, not likely. I can't believe one can pay almost $1,000, sometimes more, for a mobo that isn't some high performance server type mobo. I'm talking one that is expected to run at full tilt for many years and do cartwheels around other mobos. The prices are ridiculous. Even the board I'm getting should be priced better and I'm likely getting it at the cheapest there is to be found. I recall when SSDs first came out. Basically, you didn't want to be writing to them no more than needed. Then they got better. After a little while longer, they got to almost like a spinning rust drive. They need some special settings but other than that, they can last a really long time. I was sure that by now, they had improved even more. After all, people put windoze on them and it updates pretty regular too. I just wasn't sure how much wear the portage work directory would put on that. I suspect if I bought a cheap or no name brand, I'd need to be more concerned. Given I'm getting a Samsung which is well known for their SSDs and their quality, I wanted to be sure even tho it should be OK. I figured someone else was using one of those things. My plan, given it is a 1TB, use maybe 300GBs of it. Leave the rest blank. Have the /boot, EFI directory, root and maybe put /var on a separate partition. I figure for the boot stuff, 3GBs would be plenty for all combined. Make them large so they can grow. Make root, which would include /usr, say 150GBs. /var can be around 10GBs. My current OS is on a 160GB drive. I wish I could get the nerve up to use LVM on everything except the boot stuff, /boot and the EFI stuff. If I make them like above, I should be good for a long time. Could go much larger tho. Could use maybe 700GBs of it. I assume it would use the unused part if needed. I still don't know a lot about those things. Mostly what I see posted on this list really. Thanks to you and Rich for the replies. They both helped. Now to go dig for a 4 stick memory kit. So far, I can't find one on the Walmart site. Only pairs. I was using my cell phone tho. It's not suited for serious digging. ;-) Dale :-) :-) P. S. After I do the CPU upgrade, I'll have a spare CPU. Then I'll need another mobo, and memory set so that I can put that CPU to use. No need it sitting around on a shelf right??? ROFL
