So, given that demo, does a single SSD perform substantially better enough on a normal laptop to warrant the expenditure yet? (Last I heard, standard advice was to wait until the price drops.)
The 128gb Samsung SSD in my Dell M1330 is amazing. I don't regret a penny of the upgrade cost. When I got it, I ran benchmarks against my desktop's 10k RPM HDD:
Only if the drive is based on Intel's MLC or, even better - Samsung's SLC flash.
Regular (cheap) MLC-based SSDs are good only at reading big sequential files and lose out to 7200rpm drives when it comes to many small writes.
I can't find a ling to a guy who blogged about his disappointing experience compiling C/C++ sources on a regular MLC drive, but I googled Linus Torvald's experience with Intel:
I personally find that I just have all my software open all the time, most of what I need gets pre-cached in 4GB of RAM I have, and I never reboot, i.e. no need to restart anything [unless, of course, freaking Adobe Flash freezes my Mac]
Gives a lot of detail about the various types of SSDs and why the intel is currently the best bet. Warning, reading it might cause you to go into a "gear lust trance" and spend a lot of money.
Yes. It's definitely changed my computing life. Everything is instant and I can do things I can't do on my slightly more powerful but SSD-less work laptop.
I have a 64GB SSD in my laptop and I love it. Upon a clean Ubuntu install my system booted in 28 seconds. After tweaking my system some I got my boot time down to 12 seconds.
I tried opening OpenOffice after watching this video and found that OpenOffice writer opens in less than 1 second and opening all Office applications except for database and impress takes less than three seconds 3.
The difference between SSDs and HDs is definitely noticeable.
