revised Restoring the oxide layer of the NAND in a SSD to restore performance
Cleaned up the question to remove ambiguity.

comment How can I fit 6 7970 Graphics Cards in one computer?
Wouldn't it make more sense to wait for the 7990 dual-GPU card? That would give you six GPUs but in the space of only three ones, thus saving you the trouble of mounting six cards.

comment Will I experience problems running a Corsair Force GT SSD in IDE mode?
Not quite. If you look at the fine print of the specs for SSDs you see they apply when you run it from a native SATA controller. The Marvel usually used in the SATA expansion card is not quite as fast as the native Intel or AMD controllers and thus hurt the performance somewhat.

Modern SSD controllers use NCQ to populate as many controller channels at the same time as possible. It is somewhat similar to out of order execution. NCQ is not available in IDE mode so you loose significant performance.

comment Monitor amount of data a process writes to SSD/HDD
It was really nothing fancy. Just import the data, use stringsplit to get at the number and then add them up and put the results in a barchart.

I used Mathematica and the results are at the link I gave.

comment Monitor amount of data a process writes to SSD/HDD
I haven't found a way to do that with just Process Monitor. When I investigated writes to my SSD ( overclockers.com/forums/showthread.php?t=697061 ) I ended up exporting the log from Process Monitor and adding the number up in another program.

comment Firefox writes megabytes of data per minute to disk, why?
In about:config there is a setting called browser.sessionstore.interval. Interestingly according to it Firefox should store every 15 sec. This was not the interval I observed.

comment How to format an Intel 320 SSD to take advantages from their wear leveling function?
@DavidSchwartz: No, the controller does that, that is not the issue here. The problem arises when it does wear-leveling and garbage collection. Since it can only delete data a block at a time it is in the controllers interest to delay doing anything until all the data on the block is invalid and it doesn't need to move anything when deleting the block. But because of wear-leveling and other functions, sooner or later it must move data. Having lots of free blocks means it can delay doing these things until more of the data is invalid and doesn't need moving, thus lowering write-amplification.

comment How to format an Intel 320 SSD to take advantages from their wear leveling function?
@David Schwartz: The modern Intel drive (even though it is still the same controller) is not quite as brain dead as that document makes it sound. It will use all free space available to reduce WA. So you can partiton the entire space available and still achieve the same effect provided that a) you always make sure to leave empty space, and b) you make sure to TRIM the empty space so the controller knows it is empty. But that is the OP's problem: no TRIM.

comment How to format an Intel 320 SSD to take advantages from their wear leveling function?
@David Schwartz: It has to do with Write-Amplification. How much free space and over what area you are writing affects the WA of the drive, which in turn can have a big effect on drive endurance. Here is an old pdf from Intel discussing the matter: mralpha.s3.amazonaws.com/Intel-overprovisioning.pdf There is also more discussion over at Anandtech: anandtech.com/show/5518/…

This answer is not correct. While it is true that the Intel SSDs will do wear-leveling no matter what, the amount of writes they can handle greatly depends on free space and where you write. This is specially true for server situations or situations without TRIM.

comment Can winsxs be moved and if so how?
That discussion is true but misses a key point. On a newly installed Windows the winsxs is mostly hardlink to dlls elswhere. But when a dll is updated the old version is moved to winsxs and a hardlink to the new one is established. So if you have five versions of a dll four of them will be in winsxs and the fifth, newset one will have a hardlink to it. So after a few years of installs and updates you can end up with many GiB of real dlls in winsxs in addition to the hardlinks.
