Interesting article. I was surprised to learn SSDs do not need
defragmenting, in fact it can actually be bad for them.

Time will tell which drive is best. If SSDs come down in price as much
as HDs have over the last decade. they should be a bargain. 

At the request of another group member, I just did a test of write
speed compared to a mechanical HD. Copying a 6.038 GB file from
another HD, the mechanical drive took 4 minutes 48 seconds, while the
SSD took 5 minutes 7 seconds. The mechanical HD was faster by about
7%.

I also tested the bootup time from power on to logon sound. I
re-imaged both the mechanical HD and the SSD so they would have
identical software and partition size on both. 

The mechanical HD took 51 seconds vs 40 seconds for the SSD. The SSD
was faster by about 28%.

Hope this info is useful.
