   Hi All,

   I own an Acer Aspire 5930G and would like to install a external case for two HDDs.

   I saw the following two models:

   http://www.raidsonic.de/en/products/details.php?we_objectID=6863

   http://www.icydock.com/product/mb662us-2s.html

   On the first model is said it does not provide a eSata port multiplier (only one drive will be seen), while the second seems to have it, but the machine needs to support it.

   Hence, the question is, does my laptop support "eSata port multiplier"?

   needless to say this is the first time i have to deal with that, so i'm a bit lost.

   In the other hand, i saw there is a Express Card providing USB 3.0 ports (which i assume works without problems on my laptop), maybe that's the best way to go with? (even when the full speed will not be used)

   Thanks in advance for your advice.

   Hello diegocr,

   I assume you would prefer to configure the case with the hdd's to have data redundancy with a raid setup ? If not, I honestly don't understand why you need two. I would buy a simple USB hub and two separate external hard drives and plug both into the hub and then connect the hub to the laptop.

   The USB 3.0 card will work on your laptop as it uses your USB 2.0 port although both cases do not run on USB 3.0 as described in the specifications. So if you bought a USB 3.0 Express card, it would run on 2.0 to both mentioned devices at 480 mbps.

   The port multiplier is just the same thing as a usb hub. The difference between eSATA and USB is the connection and the speed (480 mbps and 3.0gbps). Your laptop has a combined USB 2.0 & eSATA port, which you COULD use. Now since most of you always buy stuff online, it would be useless to say to "test it first".

   I can only add that if it doesn't work, you can only use ONE drive with eSATA but BOTH drives with usb 2.0 - if you'd go for the JBOD setting if I read correctly. Since these storage cases are mostly used for 'storage' and backups, speed is not necessarily up for discussion - as transfers run casually when the time is right and backups run when no one is around. So the device is not used as a "memory stick" in the sense of extremely fast hardcore-plug-and-play-copy-paste-on-the-run action.
