I'm always reluctant to believe MTBF claims. They may be correct,
but with numbers as high as 227 years, I have no confidence in them.

Same here, but I have done the math. If every cell of a SSD can be
written to 100,000 times, it would take a person overwriting the
whole SSD 24 times a day for 11 years before you would wear one out.
That is a lot of writing. So I can see the average user might get
227 years out of one.

So I guess the bottom line is it sounds like there's really no issue
with using the SSDs to replace conventional HDs except for the price
(no matter which type, but skipping the DRAM ones, which don't seem
useful for the general consumer).

IOW, they will outlast any conventional HD (no matter what type of
SSD), and are certainly a lot faster. I'm still not sure about the
permanence of of the data stored in flash memory in terms of its
shelf life (or maybe that was expressed in its MTBF stats), but I'm
guessing that's not an real issue, either, in comparison to the
mechanical drives.

Yes that is about it. Except I wouldn't call the real cheap MLC SSD (vs.
more expensive MLC SSD and better yet SLC SSD), as fast. As they do make
some really slow MLC types. For example Super Talent has one called
FPM16GHAE PATA PCIe SSD with a read speed of 45M and a write of 15MB.

My personal experience is that HDD has an early failure rate of 3 out of
21. And they lasted a month or less. SSDs are hitting the same ratio, 1
out of 7. And they usually fail in a few months. And this one will work
if you let it sit with power for 90 minutes. So remember this trick if
you ever have one fail. And there might have been a recall on that lot.
And I believe it was a failed controller on the SSD board and not any of
the SSD chips themselves.

MTBFs are a little like statistics; you can make them say different things
at different times. Folks should remember the calcs for MTBFs are usually
for laboratory conditions of a controlled environment, etc. etc.. I
wouldn't expect to see an SSD drive last 200 years in use any more than I
would a HDD last 37 years in use. Whether it's alpha migration or physical
parts wear, neither comes out very "real" in MTBF calcs. Grease dries,
irradiation degrades and all that good stuff. I've never seen a single
instance of a product making its MTBF numbers, have you? MTBF is really
only useful (sometimes) as a comparison factor, not real numbers.
Like in the G's tests, you have no idea how the products were dropped if
they don't say so and there are many different ways of speccing how to
calculate (not measure) them.
I used to have to do a lot of MTBF on my designs and I hated it; it felt
like lying to the customers because marketing always hyped it as how long
the product would last, which it definitely is not. You CAN do actual-use
calcs for MTBFs, but it's expensive and time consuming so all most engineers
do is use the means of the various parts within a product. It has its uses,
but not in advertising, marketing or anything for the public, in reality.

Actually, HD MTBF numbers are PURE statistics!

Actually if less than 37 years holds true, I have some HDD that still
have half of their life to go. And they are still working just fine the
last time I checked. ;-)

From what I've read it'll happen over a relatively short period of time
compared to mechanicals but you also get some extra time out of it because
it quits using the bad "sectors" and moves over to other good ones. That
goes on until there's no space left unless you're watching it. I know of
some SSD drives in a CT business (UTC) where my son works, where they're
being used but not on the system drives; so far not a problem anywhere.
They're surprisingly cheap bought in quantity which tells us, I think, prime
time isn't too far off. They're using 64 Gig drives right now; really tiny
in size!

Actually all SSD that I know of uses wear leveling. This increases the
number of writes, but the whole mass storage is written to evenly. Thus
at the end of its life, the whole thing just dies. Too bad they don't
add a counter or something to let you know how far you are in its life
cycle. ;-)

Hi friends on the site there.
This is James.
My Windows XP SP3 is not getting as faster as I want and sometimes it loses the USB or not recognize the USB device. Other if it finds and when I try to remove by remove safely the drive then it denies for that. How does it happen? Give me reply.
Thanks.

Do they not have the equivalent of SMART?

Actually they do use SMART. Although SMART doesn't have SSD useful
information as a standard yet. Programs like Hard Disk Sentinel does
help in this regard though. As it keeps a running tally on how much is
written to the SSD.

I'd be very interested in going SSD as my main drive, but the lifespan is
always what scares me. I want my data to be relatively safe. Being that the
technology is newer than a hard drive is what worries me since I have no
experience with it.

SMART attributes aren't always a good measure of a drive I'm told. Different
programs read differently. I'm monitoring my drives at work and they list
33% health left. I still had a Windows 98 machine running here up until a
few months ago with the original hard drive.

If speed is your objective, and cost is not a deterrent, image your
current drive, install a SSD HD, re-install the image. "Chris Prillo" did
and says its a slam bam for performance. I would sure like to hear from
an average joe who tried it.

Hi Shawn! MTBF for SSD is 227 years. While hard drives MTBF is 37 years.

SMART attributes aren't always a good measure of a drive I'm told.
Different programs read differently. I'm monitoring my drives at work
and they list 33% health left. I still had a Windows 98 machine
running here up until a few months ago with the original hard drive.

Google research showed that SMART is unreliable. I take it as a small
gauge. But not something you should depend on 100%. As 40% of failures
are not detected by SMART.
