2 Questions about SSD drives:<br>
<br>
First, I would appreciate of someone who has SSD disk will<br>
run<br>
hdparm -t /dev/sda<br>
and post the results here. (In the spirit of the recent thread about<br>
HW for linux).<br>
<br>
I have<br>
/dev/sda:<br>
Timing buffered disk reads: 586 MB in 3.01 seconds = 194.68 MB/sec<br>
And it interests me to compare results<br>

Does a result of, let's say, 400 MB/sec, which is double speed comparing the<br>
above result, will boost a task of building a linux kernel (on a dual<br>
core machine)<br>
in about 1.5 or 2?<br>
<br>
Second question:<br>
I must admit that I am a newbie with SSD, so this question might seem<br>
obvoious to others:<br>
I saw that inner SSD disks, which are sold in stores like KSP/Ivory,<br>
are in laptop form factor (2.5'').<br>
<br>
Is there some reason that there are no inner 3.5'' disks for Desktops (there<br>
are extenal SSD which can be , so I believe, used with desktops) ?<br>
Is there something which prevent us from connecting 2.5'' inner SSD to<br>
a desktop (I mean STAT2- based or SATA3-based) ?<br>
<br></blockquote><div><br></div><div>SATA connectors for 2.5 and 3.5 drives are the same (power as well as data). You can mount your 2.5 drive in a desktop, but if you don't have any 2.5 bays (which are available in some enclosures specifically for SSD drives), there are kits of 2.5 to 3.5 brakets you can buy (e.g., <a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16817994085">http://www.newegg.com/Product/Product.aspx?Item=N82E16817994085</a> ).</div>
