What eats a lot of storage should be in Windows/Temp , you would need to log as admin to see the pointless .tmp files.

Bit growth is solid but to claim that supply is far bellow demand while reducing capacity instead of expanding it, is absurd. It's the opposite of grabbing that claimed opportunity.

There must also be a disconnect between data creation and how much of it has sufficient value to be retained long term. Even if that chart is accurate, it likely means that enough older data is being deprecated for supply to be sufficient. One could theorize that cheaper storage would allow for less data to be deprecated but that's a matter of cost not volumes- how long one keeps surveillance footage, depends on TCO not supply. At the very least they purposely ignore demand elasticity.

Seagate is stuck with HDDs and by claiming that demand is much higher than supply, they try to make the case that HDDs have a long life ahead because CAPEX for NAND is very high.


A lot of data is being generated but not all is stored long term as cost is always a factor.

Realjjj,

Thanks you for your comments. Using one chart, commenting it and giving credit to the source ought not to qualify for "lot of the data from Seagate's marketing materials." Seagate is an authority in the field of data storage and I did not question the authenticity of their chart. But I wonder if the drop in HDD production is affecting drives of less than 1 TB. Today, I would not purchase a drive with less than 1 TB, preferably 4 TB. And next year probably 10 TB. It must be tough for storage companies to keep up with such a fast moving target.

I am traveling in India, but once back to the West Coast, I will check with my contacts at other storage companies and possibly comment further.

Again, thank you for this opportunity.

@TonyTib: I like to use PortableApps (from http://www.portableapps.com ) which are all free, and includes some free disk cleaners.

CCleaner has a portable version with no installer intended for sysadmins and advanced users.

Note that sometimes you can be over-aggressive.

Which I why I recommend looking at CCleaner's configuration and making sure you understand what it will delete.  You can shoot yourself in the foot.


Another area to look is the Windows swap file, which defaults to twice your memory size. On our machines with 32G RAM, the swap file defaults to 64G - and those PC's never swap.  So I I set the initial swap size to 2G.

It's technically possible to run with no swap file, but I use a minimal one as well.  I have 8GB RAM in the current desktop (the max it will take), and I normally never see memory usage exceed 50%.

And I boot from an SSD, but have an HD as well, so the swap file is placed there.

On desktop machines, look and see if the hibernate file is there - if you have a lot of memory it can also be quite large.  I never hibernate my desktop, and thus set Windows to remove it (Google for instructions on how to do this) You probably don't want to remove it on a laptop.

I use Hibernation on a laptop, but the desktop is on 24/7.  When I went to Win10, I discovered I had to disable the new "Hybrid Shutdown" feature.  That doesn't do an actual true shutdown, and on my machine, required a power cycle to shut it down.  (I dual boot Windows and Linux, and sometimes want to be in Linux instead of Windows.)  So no hiberfile.sys file here.  MS makes the blithe assumption the world is running on a laptop where battery power is the scarce resource, and everyone wants to suspend and resume as quickly as possible.  Er, no...

@jimforbroadcom: Thanks, Dennis.  I will check out CCleaner.  I've tried CleanSweep before and wasn't too impressed.

I haven't looked at CleanSweep.  I've been using CCleaner since the old days when it was called Crap Cleaner.  There's a payware Pro version with more features, but I haven't needed it.  It will also optionally check for newer versions and offer to send you to where you can get them.

CCleaner installs right-click context-menu shortcuts on the Recycle Bin to open it or run it.  Open it, tell it to Analyze, and it will scan the system and return a list of what it will remove.  You can fine tune that if desired.

By default, it empties the Recycle Bin, and deletes various junk files elsewhere.  It does warn you it's an actual delete operation, and be sure you want what it will clean to go away.

Install it, open it, and spend a bit of time in the Windows and Applications section to fine tune what it removes.  Once you've done that, you should just be able to run it periodically.

Messy housekeeping?  I can relate.  If we could attach photos I'd show you my desk and lab benches.  They'd almost make Bob Pease or Jim Williams blush!

I had a co-worker a while back whose office was like that.  He didn't have a problem because he knew what pile to look under, but $DEITY help anyone else who had to find something in his office if he was out...

@jimforbroadcom:  No, I don't spend a lot of time or effort on garbage collection, and I don't really believe I should have to.

In an ideal world, I'd agree. In the imperfect world we live in, you do need to expend some effort.  That doesn't mean doing it manually.  That means installing tools to do it, teaching them what junk is, and running them on occasion.

I recommend a freeware application called CCleaner from an outfit called Piriform.  CCleaner is used to delete junk files created by the OS and applications, and has a steadily increasing number of apps whose junk it knows how to clean.  You need to configure precisely what it will count as junk and delete, but that's a one time exercise.

The late husband of a friend was a sloppy housekeeper and didn't throw stuff out, and extended the bad habit to his PC.  His widow asked me to look at it, and CCleaner removed gigabytes of junk and made it useful.

Running Windows 7.  I don't remember the exact files.  Our IT helpdesk tech remoted into my computer and deleted the unnecessary junk.  No, I don't spend a lot of time or effort on garbage collection, and I don't really believe I should have to.  This is a computer, after all.  It's like the old days of UNIX engineering workstations when you had to RM CORE every week or so or the computer would drown in its own $#!+  Sigh...

@jimforbroadcom: So tell me why my 237 GB hard drive recently got completely filled up!  I had to get IT help to delete a few 10's of GB of unnecessary files just to get my laptop computer to work again!

What OS is on your laptop, and what sort of useless files were those?

I'm fussy about digital housekeeping, what gets stored locally, and precisely where it's put, and I periodically throw out the trash to keep things tidy.

It sounds a lot like you don't have a process in place to manage such things, and need one.
