In addition to disabling the pagefile system, I disabled a
couple more things:


Disable Background auto-layout:

Key Name:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Op
timalLayout Value Name: EnableAutoLayout Type: REG_DWORD Value:
0


Disable Prefetch

Key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session
Manager\Memory Management\PrefetchParameters Name:
EnablePrefetcher Type: REG_DWORD Value: 0


The above made perfect sense.


But I am not too sure I want to do this one:


Disable update of filesystem's "last access timestamps"

"Key Name:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
Name: NtfsDisableLastAccessUpdate Type: REG_DWORD Value: 1


All of the above are from this article:

He talks about valuable info but doesn't explain his

well enough to judge. But I do disable indexing and
generally disable unnecessary services. When I check the
number of writes on my system it's miniscule compared
to the projected life of the drive. I also don't scrimp
on drives. They're not very expensive. I don't need a

that before they get too old. I haven't had any problems
with SSD.

File system's last access time updates generally occurs more frequently than both defrag-on-idle and prefetch (on program execution). Adding to that, the system also writes event logs and registry from time to time which mostly
based on events. Write cache won't help much, since the location of the
written data will likely be scattered throughout the disk. It'll simply
delay the disk write operations.

It's recommended to use a tool to temporarily monitor applications which are used daily. Just to find out how frequent they perform disk operations which are not cached. Both read and write.

FYI, anti-virus is a heavy disk accessor, since when an executable file is loaded, the system simply maps the file into memory. While the system do
have to read the file's header part, it doesn't actually need read the other parts of the file until a code needs to be executed, or a data needs to be read. IOTW, the system doesn't have to read the whole executable file when
it's being loaded. But not for anti virus, where it must scan all data in
files which are being loaded, be it executables or not. While data is cached into memory and the cache capacity will auto resize itself as needed,
there's still a limit of how much it can grow. Not to mention that, it will shrink if applications allocate more memory when there's no free memory
space left. The cache won't guarantee that all files' data are kept in the cache.

And FYI, these don't apply to just XP. They apply to all OSes.

Hello Newyana2!

He talks about valuable info but doesn't explain his
reasoning with those settings. I don't understand them
well enough to judge.

I think it's all about avoiding "writes".

But I do disable indexing and
generally disable unnecessary services.

I still have a pile of services running. But indexing sounds
like a good candidate to turn off.

When I check the
number of writes on my system it's miniscule compared
to the projected life of the drive.

How do you use to "check the number of writes"?

I also don't scrimp on drives. They're not very expensive. I
don't need a big one. So I mantain 2 500 GB drives on each
machine and mirror the data. About $50 to replace. I
generally do that before they get too old. I haven't had any
problems with SSD.

Well.. this 1TB drive is my first. Now, I need I need a 2TB or
larger HDD/SSD just to do image backups.

Most likely, NtfsDisableLastAccessUpdate would be disabled on
Win10 or Win11 machines as well, by Microsoft. On winXP, you do that
yourself.

Right in the main window: Total Host Writes

I don't really worry about it and don't often look at it. My
writes are currently under 1 TB. I calculated it once and according
to the experts, the Midwest US may be an ocean again
before I exhaust the write capacity. So I just watch for any
write problems that might indicate failure, and I don't push it.
At about $50 each, I think of disks like car tires. You don't wait
until one blows out. If it's getting old I just replace it.

CrystalDiskInfo 8.4.2 shows

F6 Total Host Sector Writes <=== Raw data is sectors
F7 Host Program Page Count
F8 Background Program Page Count

Your F6 shows Vendor Specific and 376A7BCB
or 929,725,387 sectors or 464,862,693 KB
or 453,967 MB or 443GB.

Where your Health Status in the upper left says "Good"
it should say "Good 99%" or the like. Your drive is
360 TBW so you've used approximately 1/720 of life
(0.1%).

Since you just cloned it, day to day writes will
be a lower/different number than the cloning incident.
If there were a "projected lifespan", it should grow
with time.

If you edit raw videos (200GB) on it 12 hours a day, yes, that'll
make a dent. But just web surfing (cache set to use RAM and
not disk), it'll last a hell of a long time.

Are you sure that's not something else pushing ads? I don't see
any code for that in their source. Though I also don't generally
enable script. They do try to load script from usefulcontentsites.com.
What I see, not needing any script, is the picture I uploaded, on a
gray background, with not much else.

Why not use HOSTS file and/or NoScript, uBlock Origin,
etc. The bulk of the crap on websites is unsafe and need
not be loaded.

I don't know where it gets that. It's probably about 4 years old.
It must count every time it wakes from sleep. I usually only
turn it off at night, but I put it on sleep whenever I leave it.
That could typically be 5+ times per day.

When I invoke nextdns, the site responds very fast and no
scripting. Only your image shows up. So.. nextdns seems to be
the key to success here.

etc. The bulk of the crap on websites is unsafe and need

The HOSTS file - how?

I tried uBlock in the past but it seemed abit confusing to and
frustrating to constantly make adjustments to the sites that I
really need to use frequently.

Nextdns seems simpler and works without added programming.

In any case, SSDs of today are quite long lasting for the
average user, and TRIM is not critical - only nice to have.

This the report of a friend's 250GB SSD. It's over 8 yrs old,
and never saw a TRIM.

I didn't know about NextDNS. That sounds like a good
solution if you trust them. HOSTS and extensions are
more work to set up.

I forgot to post the following with that. It's the structure of

The Linux partions have undergone many installs, reinstalls and
experimentation of various distros over the years.

So.. not bad for a roughly 7-8 yr old SSD, without TRIM.
