Ordered the SSD from newegg.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820167013
It comes in a small box with the SSD and a single page about how to
install the SSD. Attached it to a 2.5-3.5" converter so it would fit in a
standard case.
====
When I got the SSD, it showed 54 hours of usage and 66 power cycles, I
assume this is testing at the factory, in any case, this is what the smart
stats look like and some basic dd speed tests, as shown in the techreport
review, write speed is quite fast, 227MiB/s.
The machine used to take about 60-70 seconds to boot, it now takes about
5-6 seconds.
When opening browsers etc, I no longer hear my (previously) 750 gig disk
grinding away loading all the libraries, everything is instantaneous.
====
Btw, no temp sensor.

Due to the 100k write cycle lifetime, I will not be performing any
more benchmarks on the SSD itself, such benchmarks are available on
techreport.com but just wanted to send out the smart data for the
smartmontools list and point out it is working with linux+ich7+xfs.
Overall, whenever I do anything now its just like the entire machine is
sitting in a ramdisk (similar when you boot knoppix and load to ramdisk).
The techreport benchmarks are here:

Ordered the SSD from newegg.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820167013
It comes in a small box with the SSD and a single page about how to
install the SSD. Attached it to a 2.5-3.5" converter so it would fit in a
standard case.
====
When I got the SSD, it showed 54 hours of usage and 66 power cycles, I
assume this is testing at the factory, in any case, this is what the smart
stats look like and some basic dd speed tests, as shown in the techreport
review, write speed is quite fast, 227MiB/s.
The machine used to take about 60-70 seconds to boot, it now takes about
5-6 seconds.
When opening browsers etc, I no longer hear my (previously) 750 gig disk
grinding away loading all the libraries, everything is instantaneous.
====
Btw, no temp sensor.

Due to the 100k write cycle lifetime, I will not be performing any
more benchmarks on the SSD itself, such benchmarks are available on
techreport.com but just wanted to send out the smart data for the
smartmontools list and point out it is working with linux+ich7+xfs.
Overall, whenever I do anything now its just like the entire machine is
sitting in a ramdisk (similar when you boot knoppix and load to ramdisk).
The techreport benchmarks are here:

Very nice figures there, interesting to see the initial 54 hours usage

Actually I'd like to know... how does it behave during powerfails
while it is being written to?
Flashes I seen (USB / SD) developed bad sectors in that case, and
ext2/ext3 can't handle that. (And I don't think xfs can handle that
either).

I have a UPS for all of my machines, so that will not be a problem in my
case. I do not wish to trash a $720 SSD or my current install, if someone
else wants to try feel free though :)
With barriers, presumably it would be safe-- but as always, a UPS/and
barriers and/or RAID, there is no excuse not to have regular backups
incase of a failure at any time..
I do recall however one instance where there was an apt-get dist-upgrade
going and the power was cut to a machine on purpose (before/not
using barriers) and suffice to say-- it got mucked/suffered many corruptions
all over the place.

Hi guys, can you take smartmontools-database-owner@lists.sourceforge.net
out of cc please? The list owner can't help with your discussion ;) Did
you mean smartmontools-database@.. ? Though that list is for collecting
hard disk data.
HTH,
Volker (list admin)

UPSs fail too.

I've done various powerfail tests with and X25-M and as expect it
behaves perfectly fine as long as you either disable the write cache
or use barriers. The default ext3 setup without barriers corrupts
the filesystem left, right and center, but that's the same as other
recent disk drives with large caches.
