difference between SAS Drive Technology : Large-LFF and Small-SSF

Dear all;

What is the difference between SAS Drive Technology : Large-LFF and Small-SSF, and which is better ?

thanks

The main advantage of SFF is that it is still now, only available for small disks and is very quieter and more reliable than the other ones, it is also very smaller. If you look at the HP Compaq 6000 Pro, you will notice that it is small form factor PC. The best part is that you can choose the Intel processors for it, the Intel Q43 express chipset, DDR3 Memory, and integrated dual display capability help you get the job done and much more. Read more about it here.

what do you mean by it is still now, and more reliable than the other ones?
Is that means the SAS LFF is out of the market ?and it's not reliable?
you know I'm going to take this server:

Part number: 470065-300
HP ProLiant DL380G6 E5520/3x2GB RAM/1x300GB 15K SAS
HDD/1x460W/ Rack Server

The drive is 300 G/15k SAS LFF

that's why i'm asking? is it a good server to act as a domain controller?

thanks

I think that there isnt any problem with your server specs, it is just fine. Usually SAS is the successor to SCSI, so it is not an issue having it. SAS is a serial technology where every drive can have it's own dedicated 'pipe' or bandwidth lane to the SAS RAID controller as opposed to traditional Parallel SCSI whose drives share a 'pipe' to a single channel on the SCSI RAID controller.

Thank you and best regards
