Hello All,

To let you know our opinion (from the point of view as recovery products
and services company):

USDB HDD can be used only for backups. Database should be on RAID1/5/10
(according to your budget).

> 2) Pen Drive : more compact.

Welcome to our recovery service :)

We have tested RAM Disks - no performance advantages found when
comparing to the properly tuned Firebird.

With best regards,
