I use an SSD in my laptop. However, the failure rate with some manufacturers
SSDs is horrific. A disk drive, when it crashes, you can often still get
critical data off of it. An SSD either (a) soft-errors and causes random data
corruption and windows crashes, or (b) hard locks instantly. Either way, you
aren't getting valid data off of it.
If you use an SSD, have a really good
backup strategy that keeps a history of changes. I use rsync. Apple's Time
Machine would work too. I have not had any Intel SSDs fail yet. I have had a
significant number of failures with the other major manufacturer's SSDs.
If
you use a hard drive, make sure it is in a computer, and is periodically scanned
to verify the integrity of the backup. I've been noticing that the newer hard
drives can fail silently. They have such large capacities, you won't find out
it is failed until it is way too late to copy the data off. I've caught two
drives in the portable carriers silently failing. As such, I've been doing my
current backups to full computers (not portable drives.) This way I can verify
the "backup" is actually a backup by reading the data back.
If you run
Linux, try:
rsync --checksum --backup --backup-dir=backdir
-avS indir outdir
The --checksum forces complete file reads,
and will alert you if your storage media on either side is unreliable. The
--backup option prevents rsync from deleting the old data files, as the failure
could either be an unreliable SSD on the laptop or a unreliable (portable) hard
drive on the desktop. [ Reply to This | Parent | # ]

One further follow up: When running Linux with most of the newer SSDs, it is
no longer necessary to do a special track/cluster format with Linux to get
maximum drive life. Simply install Linux as normal, and disable the paging
partition.
Windows 7 on the other hand, has a bug with certain models of SSDs
where if the computer goes into suspend, then the SSD stops responding
permanently. By default, Windows 7 loves to suspend on a laptop. I've seen
Windows 7 go to suspend during system updates in Windows 7. The good news is
that the manufacturer will send you a new (blank) SSD if you have been bitten by
this bug during the warranty period.
Other disadvantages of Windows 7 with
SSDs are:
- Windows 7 likes to have a page file, which wears out SSDs
quickly.
- The disk footprint of Windows 7 with Office and Antivirus is
typically larger than that of Linux with LibreOffice.
- Linux often boots
quicker than Windows 7 if suspend is not used.
Lesson: If you are going to
use SSDs on a laptop, run Linux. [ Reply to This | Parent | # ]

SSD's can fail too, I set Mageia up on one for a brother it worked for one month
has now corrupted and failed 4 times in a week. It now has corrupt sectors that
Mageia will not allow it to format or repair.
Unfortunately from the other normal HD in the system running Windows 7 it is
still able to format and or repair it. Shame it ran blisteringly quick and is
back to the supplier this weekend. It isn't due to a system hardware failure it
is the SSD![ Reply to This | Parent | # ]

I'm running my SSD based laptop with Solaris 11 x64 - loving it (SSD coupled
with ZFS - match made in Cyber-Nirvanna), FDE goodness to boot.[ Reply to This | Parent | # ]
