I've been trying different setups; on Win XP Pro x64, Win 7x64, different controllers (on-board CERC and Adaptec 1430SA), using manually adjusted partitions (XP x64), running Intel SSD Toolbox, proceeding recommended optimalisations and NOTHING HELPS.</P><P></P><P>Bandwidth seems to be cut on certain level, see the atto results.</P><P></P><P>Read speed is, let's say, satisfying: ~200 MB/s (on 1430SA). </P><P></P><P>Magic 50 MB/s is not to overleap. If you have experienced similar problem and found the solution please share.</P> Mon, 22 Aug 2011 11:44:31 GMT https://community.solidigm.com/t5/archive/intel-ssd-on-dell-precision-workstation-670-slow-write-speed/m-p/14346#M9589 idata 2011-08-22T11:44:31Z https://community.solidigm.com/t5/archive/intel-ssd-on-dell-precision-workstation-670-slow-write-speed/m-p/14347#M9590 <P>Intel 320 SSD 40GB 45MB sustained write is according the specifications.</P><P></P> Mon, 22 Aug 2011 13:27:23 GMT https://community.solidigm.com/t5/archive/intel-ssd-on-dell-precision-workstation-670-slow-write-speed/m-p/14347#M9590 idata 2011-08-22T13:27:23Z https://community.solidigm.com/t5/archive/intel-ssd-on-dell-precision-workstation-670-slow-write-speed/m-p/14348#M9591 <P>OK.
