There is no fix recommended size, it depends on what storage hardware you have, please read the following docs:

If you google for it, you'll see that folks generally use very small storage blobs for quorum.  On Sun HDS storage, I've use the smallest LUN device support by the array for quorum devices e.g. OPEN-E LUNs.  I've seen other folks use devices as small as 50MB or even 20MB.  The actual "storage" on your quorum device is actually ignored and never used.  The quorum device must be shared and for clusters with more then 2 nodes must support SCSI-3 PGR.  2 node clusters use PGRE.  The PGR keys for all the nodes in the cluster are registerd onto the quorum device(s) in a private area outside of the actual data section of your quorum disk - as I recall that is.
