It's quite popular nowadays for consumers and enthusiasts alike to own at least one or two external hard drives and hot swap them for data logistic purposes. Unfortunately, most of these devices are limited to either eSATA, USB or Firewire on the external interface. These products certainly make mass data storage dvices more portable and accessible, but its nature makes it only a temporary means of physical storage (Placing it on your desk and using it in a permanent fashion doesn't really cut it). For those users that want the convenience of an external drive and performance of an internal drive, but without the fixed format of an internal drive, an internal hot swapping bay may be a viable solution -- making it extremely convenient to swap hard drives, yet taken into a semi-permanent space. Let's say you have five people who wants to use a single computer, but does not want to mess around with the data on one hard drive, and penta-booting is not an appropriate way of solving this problem. Solution: Have five hard drive, one for each user, and let each user plug in their own hard drive for their own usage session. That may not be everyone's case, but hey -- we're just giving a possible scenario. Today, we will be taking a look at the iStarUSA T5F-SS, an internal SATA hard drive hot swap bay. I have to admit I never heard of iStarUSA before writing this review, but they do seem to be a long standing maker of OEM and ODM products.
