https://community.hpe.com/t5/disk-enclosures/mixed-disk-question/m-p/3687957#M18699 Sorry that this is such a basic question but...<BR /><BR />I have an MSA30 with 14 x 146gb drives in. I am trying to get my company to upgrade to 300gb drives but they asked me if it's possible for them only to buy 5 and not 14 - Is this possible or will it just not work ?

You will find that the extra space (154Gb) on the 300Gb discs will not be used.<BR /><BR />Jeff Thu, 08 Dec 2005 19:38:44 GMT https://community.hpe.com/t5/disk-enclosures/mixed-disk-question/m-p/3687958#M18700 Jefferson Humber 2005-12-08T19:38:44Z https://community.hpe.com/t5/disk-enclosures/mixed-disk-question/m-p/3687959#M18701 Thanks Jeff Thu, 08 Dec 2005 19:43:11 GMT https://community.hpe.com/t5/disk-enclosures/mixed-disk-question/m-p/3687959#M18701 Gary Fossella 2005-12-08T19:43:11Z
