There is only so much time to worry about these details in a bigger picture of things. My bigger picture involves catching up with maintenance requirements on five computers, adding drives to my server, cleaning up offending sources of red and yellow event log entries, discovering failed RAM modules and getting them ready for RMA.
But I briefly looked into this -- may even have posted a thread and question about it.
Lo and behold! When I replaced my SSD+HDD ISRT configuration with a single Sammy 840 Pro, I find that "Magician" had it covered. Usually, the size of the swap-file is equal to the size of RAM; Magician suggests letting it vary between 200MB and some larger amount which is still a fraction of the default.
But the consensus seems to be this. You may tweak the default swap-file size, but it "does good" and does no harm.
Everybody frets and frets about the prospective life-span of their SSD. Two years ago, a friend told me he bought a Sammy 830 SSD and was happier'n-a-pig-in-s*** with it. Now he's telling me that performance has declined, and it looks to be "goin' south." But my friend has a penchant for collecting old hardware and skimping on his OS upgrade expenditures. He was using it with either a Win XP or Vista-32 install. After my consultation, he is now focused on whether the drive is getting "TRIM." Only with my vague recollections of a table published at the M$ web-site, I'm pretty sure that he wasn't getting TRIM on his SSD.
We spent the big bucks for these SSDs, and we were assured they'd last ten years. But everyone is so worried about writes and re-writes to the drives.
Do we have any panic threads from people saying "Oh, no! My SSD took a dump, and I was using it thus and such a way!" . .. ?
The only thing I worry about at the moment is Samsung's S***A** tech support. Magician tells me I don't need it, but I cannot be absolutely certain as to when and if I will.
