Anything which swaps out a lot or otherwise carries out a lot of disk writes will be bad for solid state drives, as flash memory has limited rewrite cycles, beyond which the memory will begin to degrade. I don't know the extent to which this affects SSD, but it is certainly a consideration for Compact Flash.

So basically, you want an OS which doesn't use vast amounts of RAM to reduce swapping, and doesn't access the disk unless it's actually doing anything. Windows is therefore not ideal, as it seems to use the swap file all the time, and also seems to be carrying out disk activity for certain purposes even when the machine is supposedly idle.

Probably the best bet would be a light-weight Linux distro which has a small memory footprint and has minimal background services running.

well you can always completely disable swap file.

Better sorry than worry.

If you disable the swap file then it should use physical RAM. But if you don't have enough then you will have problems, as Windows appears not to cope well if it starts running out of physical RAM when there is no swap file.

Any Linux should do.
I run Debian Lenny with KDE on my Eee 900.
Performance is good with 2Gb of RAM, even when I have a few server apps running.
As a comparison I have dual boot to WinXP Pro, and it does work ok, but performance wise it is not even near Debian.

According to some white papers I read on SSD's, you can write to them and erase the whole card every day for about 21 years though I don't believe they will last quite that long.  Depending on the manufacturer, they will warranty it for 2, 5 or 10 years.  It all depends on the manufacturer because they may use different switches or have different quality and your hardware or software needs to use wear leveling technology.  There are also people who want to defrag their solid state drive and the truth is there is no need because a study has shown there is no benefit speed wise to defragging your SSD drive.

Some of the manufacturers have white papers online and most of the public believes the myth they must wear out really quick.

I disabled all swap files but winXP still accesses my HDD every few seconds  :madashell:

how does one configure an ubuntu for no swap ? disabling the swap partition will do ?

does anyone know a good ram drive for winXP ?

I'm not sure you can have no swap easily, however you can definately tune the kernel to discourage swapping.

You could try setting /proc/sys/vm/swappiness to zero. You can just echo into it on a running system or you can set vm.swappiness in sysctl.conf

Could be anything, first things to check are microsoft components though, indexing and windows update are usual suspects.
Restraining orders are just another way of saying I love you!

Be very careful not to try to defrag or REFORMAT these puppies low level. It will KILL the drive according to people I know that have these.. Try adding an 8 GIG SD Memory card and moving the swap file to it, similarly if you were in vista or win 7 you could readyboost the device..

ok, first ... why would you want to low level format it if indeed it is possible?

second, in the case of windows you cant use a removable drive for the PAGE file.
