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.

Incase you are wondering, both disks are using no barriers.

========================================================

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:
