PC Stats has posted a review on the Portwell EZDRV-300NCF
Every once in a while we stubble across a really useful product. The Portwell EZDRV-300 fits into a 5.25" drive bay, and what makes it really unique is that is contains a CD-ROM, floppy drive and hard drive in just one bay! The unit manages to squeeze in all these things because it uses drives originally designed for notebooks - stack up an ultra-thin CD-ROM, FDD, and a 3.5" HDD and they are less than 40mm in height.Read more
Ultimately this set of drives is the perfect space saver for cases which have run out of free bays, for serves where expansion space is always limited, or for anyone faced with installing or testing lots of computers (like a IT person) that generally carries around a HDD, FDD and CDROM taped together to get the job done. Of course that last one won´t apply to many of you, but in terms of space saving capabilities this is one very compact solution. It can give any server, or for that matter any case, some well deserved extra room for burners, zip drives, RAID drives, or whatever.
