This is a hot discussion topic that won't be settled here...but
Aren't most large flash drives MLC now?
Consider the case where your flash drive is full except for one block.
You have a continually updated log file that writes OFTEN.
With no wear leveling, you've got big trouble.
With excellent wear leveling, it may not matter at all.
And wear leveling is probably not in the spec or discoverable by
legal means.  I'd expect a usb flash to have little and a SSD to
have a LOT of wear leveling.  YMMV.

I just don't buy into 4000 years life.
I've seen anecdotal reports on wearing out a flash drive in a month
with windows without taking any precautions to limit writes.
People who used the embedded windows tools to limit writes fared much

Only those cheap no-name flash has no wear leveling. And what happens is
like any other drive. The area is marked as bad and the capacity gets
less and less. All of the information still stays save though.

I know a guy who claims that those cheap no-name flash drives only lasts
him 2 months on average. He runs VMs on them with tons of writing. Shall
I say constant writing on them.

I on the other hand, have never worn out a single flash yet. And in the
beginning, I used to worry about writing to them a lot. But after no
failures in all of these years, I have dropped my guard.

And in the newsgroups, I don't hear of anybody complaining of flash
drive failures except the cheap ones. Adata for example, I haven't heard
one reported case yet.

I have three 16GB adata flash drives for two years now and no problems
with them yet. And writing to them on average 100MB per day, it would
take thousands of years to write each cell 100,000 times.

My SSD are not failing and my flash drives are not either. Let's see, I
have 5 SSD and 12 flash drives. And I decided not to worry about them
until one or two of them had failed. So far (knock on wood), no problems
to report. ;-)

Nonsense. MTBF for solid state drives are 227 years. 7 times longer than
hard drives. Writing 100MB per day to a 4GB flash would take like 4,000
years to wear it out. To wear one out very quickly, I would have to
overwrite it completely 24 times per day for the next 11 years before it
was toast.

Secondly what everybody is missing completely is the netbook also has a
4GB solid state drive (aka flash drive). So you are moving stuff from
one flash drive to another. The one in the netbook is soldered in place
and cost $150 to replace (if you do it yourself). And the one you all
are worried about costs $8 and can be replaced in a second.

Not all flash drives are created equal for one. They come in different
speeds for both read and write. And there are two types of flash. SLC
and MLC types. The later are much slower at writing than SLC types are.
And the vast majority of the time things in the Program Files folder are
only being read and not written too.

Incorrect. You cannot use mount a drive in a FAT32 folder. It must be
formatted in NTFS.

You propose to install a 240GB hard drive in a netbook which has a solid
state drive soldered on the motherboard? How in the world are you going
to pull that off? I do have two netbooks with replaceable solid state
drives. But they use PCIe connections and 2.5 inch hard drives don't
fit. There just isn't enough room inside for one.

Secondly, you just believe you can wear out a flash drive. Cheap ones,
you probably can. As they can only handle a few thousand writes and they
are toast. Others won't die in your lifetime. ADATA for example
guarantees theirs for life. Or you get a free replacement.

Thirdly, your hard drive suggestion is a very expensive option when you
want portability. As hard drives are lucky to get just a years worth of
use while being moved around. This is do to vibrations and shock. I just
got two disk errors show up in my event logs just this morning while
using this laptop on my lap. Yet SMART shows 100% healthy. With flash,
you can move around all you want too. Even go on a Space Shuttle launch
if you want (this is what NASA uses for their computers).

Fourth, solid state drives are usually faster than hard drives. It isn't
uncommon to have half of the boot time when moving to a flash drive vs.
a hard drive. In the next couple of years, I will replace all four of my
laptops hard drives with flash drives. One of them that lives mostly in
a dock, can't even be undocked while running do to the fact that disk
errors will appear in the event log. Moving to flash drive, this problem
