I have been running the SSD cards for the last two years. Windoze has a problem with the card drivers - it can't boot off the card before you load the OS (duh!) but it works fine as a secondary drive. Fedora booted right up on them, but that's Fedora.<br>
<br>It is true that the SSD technology degrades over time, but when you look at the numbers in a real world scenario it simply doesn't make any difference. You would have to be running your machine 24/7 crunching data for 5 years before you saw any degradation, and how many of your top line servers are still current after five years of technology change? After reading a number of white papers on the technology I turned on swap and indexing on the SSD card and saw another good increase in responsiveness.<br>
<br>If you stick with the drive form factor (which is performance limited by bus speed) you don't see the driver problems I ran into with the cards.<br><br>Here are the cards I'm running:<br><a href="http://www.ocztechnology.com/ocz-revodrive-x2-pci-express-ssd.html" target="_blank">http://www.ocztechnology.com/ocz-revodrive-x2-pci-express-ssd.html</a><br>
740MB/s sequential speeds and random small file writes up to 120,000 IOPS<br><br>Which is higher than the comparable SATA form factor SSDs available at the time<br>Here are the current 3.5" format drives from the same manufacturer:<br>

The price has fallen where they're worth putting into an older system to bring it back to life.<br><br>Matt<br><br clear="all">---------<br><b style="color:rgb(51,102,102)">Matthew Campbell</b><br><font size="1">Storage Solution Consultant<br>

</div>My two year old notes say:<br>
1) the only disks worth even thinking about are Intel's<br>
2) and even so they're no good for heavy disk crunching (like<br>
repeated building of complex C++ projects like chrome;<br>
it starts off fast but then degrades.)<br>
<br>
My wife's been using a 100GB one for a year or two<br>
just to hold Windows 7, all her data is on a real disk.<br>
Boot times are indeed significantly faster.<br>
<br>
If I got one for Linux, I would put just the OS on it,<br>
not /var and not /home. But then I also don't buy<br>
cars with power windows.<br>
