Usually it even uses the same interfaces (SATA or SAS) as regular disks.<BR /><BR />One of the main advantages of a SSD is that its seek time is effectively _zero_. Because of this, defragmenting a SSD is pointless.<BR /><BR />In a system where disk performance is the limiting factor of overall system performance, using SSDs in place of regular disks can really speed up the system.<BR /><BR />MK Tue, 01 Jun 2010 03:47:25 GMT https://community.hpe.com/t5/proliant-servers-ml-dl-sl/ssd/m-p/4640347#M102957 Matti_Kurkela 2010-06-01T03:47:25Z https://community.hpe.com/t5/proliant-servers-ml-dl-sl/ssd/m-p/4640348#M102958 hi ess,<BR /><BR />check this link :<BR /><BR /><A href="http://en.wikipedia.org/wiki/Solid_state_drive" target="_blank">http://en.wikipedia.org/wiki/Solid_state_drive</A><BR /><BR />i think there is very good explanation.<BR /><BR />mikap Tue, 01 Jun 2010 04:11:10 GMT https://community.hpe.com/t5/proliant-servers-ml-dl-sl/ssd/m-p/4640348#M102958 Michal Kapalka (mikap) 2010-06-01T04:11:10Z
