Which SSD?

Not strictly a Win 7 question but folk here seem more sensible than some
other groups I've looked at.
Looking at Samsung SSD 840 EVO he
http://www.amazon.co.uk/Samsung-2-5-...ds=samsung+ssd
and Crucial BX200 he
http://www.amazon.co.uk/Crucial-BX20...ds=samsung+ssd
and can't decide.
Not too concerned about a few points here and there on speed, more concerned
with reliability. The Crucial states 3 year warranty, the Samsung doesn't
mention warranty so I'm assuming only the usual 1 year.
I replaced a failed HDD in daughters laptop with a 250GB Samsung SSD and the
difference was striking, like going from a Lada to a Ferrari.
Any opinions or advice welcome.

That Samsung is £25 cheaper than at Curry's where I bought mine well
over a year ago.

I've never had a spot of trouble with it. And a few weeks ago I did a
full scan with HDTune just to see how it was faring. Not a single dodgy
sector.

It has my full recommendation.
I have no experience of the Crucial one.

Have you tried alt.comp.hardware and/or alt.comp.hardware.pc-homebuilt?

850 EVO

A very good drive. Recently installed it because the old SSD became too
filled up. Runs very fast. And there are some handy tools with it.

For better or for worse, I just bought a new System SSD based on

Thanks for the replies, have ordered the Samsung.

Samsung

There are two grades of Samsung.
Pay a little more and it is a 10 YEAR warranty.

I know, I have three installed.

Now as to performance.
It totally depends on your PC chipset.

On two old laptops, Fujitsu, one had minor speed performance
improvements but a lot lower power usage. Still worth it!
On the other old Fujitsu it had significantly better on speed
performance. Definitely worth it.
On my new Toshiba laptop it had speed of light improvement (in a vacuum,
lol). It goes without saying, but I will. Wow!

You get Samsung Magician software to tune the SSDs. All features
available on my Toshiba.
The PC chipset needs to support the Magician capabilities too for best
integration.
One old PC did not like Magician.
But the SSD still works well there and does give some speed and lower
power and on top of that it has a 10 year warranty so I is worth the
effort and cost.

P.S. backup your data anyway!

It's an Acer laptop about 9 months old, Intel 4 core I5 CPU & 4GB RAM but
have been a bit disappointed with it's performance, hoping SSD will improve
it.

I find that Magician's "RAPID Mode" works; uses about 1GB of RAM for
fast caching, and probably needs 64-bit architecture.

You were wasting your time, because you will never see a bad sector on
an SSD.

Almost certainly yes. You'll be very happy with the performance
increase.

No time wasted at all. HD Tune works well with SSDs; whether it reports
them as blocks or sectors.

He is commenting on the sparing mechanism.

On a regular hard drive, a "spare" sector must
live in the neighborhood of a "defective" sector,
to take the place of the defective one.

Because of that, a bad spot on the disk can rapidly
deplete the supply of usable spare sectors. Once
there are none left, a sector can have a "CRC error"
because the automatic sparing is no longer able to
repair it. That's when you start to see sectors
with the CRC error status. They can no longer
be repairs.

The SSD has no "geographical" limit to sparing. The
entire device relies on indirection. LBA 0 could be
at location 1234. LBA 1 could be at location 5678.
The layout is not guaranteed to be "linear" inside.
It's a jumble. Without the information in the
lookup table, you'd never be able to figure out
where anything went.

When a sector goes bad in that jumble, something
from the sparing section can be used. It doesn't
matter where that spare is located, it could
be at 2468, the seek time to *any* location
is the same.

So all that happens, is a lookup table is
updated with the "new" jumbled order. One
of the table entries has a new value. The
HDTune benchmark performance remains consistent.

When the entire global population of spares
is used up, then, the drive will issue some
kind of complaint. I don't know though,
exactly what SMART statistic would "blow"
if that happens :-)

*******

Some brands of SSDs shut down, when the
theoretical wear life is exceeded, so there
are some properties of SSDs that the owner
should research, such as the end-of-life
behavior. Intel branded devices have
particularly obnoxious behavior (I would
call it "Enterprise compatible" behavior,
because it assumes the user is showered
in backups). Most home users are not
really prepared for the end of life
process of their SSD, which is why the
warning is delivered. I would expect the
average user, to have no backup for their
SSD at all. And if one day, out of the
blue, it would neither read nor write,
they'd lose their data (no backup).
This isn't a hardware failure, it is a
policy decision.

I disagree.

I have had memory sticks that did go bad. One would not accept
one directory structure's files without throwing an error on copying.
(Caught by verify?) I replaced the memory stick, and the new memory
stick works just fine.
