External Storage questions in Home Storage and Computer Hardware Posted October 29, 2015 · Report reply I decided to buy something cheaper the first time so I am thinking about these two external enclosures: 1. Ultra U12-42069 USB 2.0 Dual Bay External HD Enclosure http://www.amazon.com/Ultra-USB-Dual-External-Enclosure/dp/B009A8ZID2 2. Rosewill Aluminum 3.5-Inch USB 2.0 DUAL BAY External Enclosure R2-JBOD Black http://www.amazon.com/Rosewill-Aluminum-3-5-Inch-Enclosure-R2-JBOD/dp/B004AA0QO6 They have good reviews, has anyone of you guys had any experience with these external enclosures? I want to put 2 HDs inside and use them as separate HDs (I don't want RAID for now), I hope I can do this with these 2 external enclosures. I have an interesting question now, both of these external enclosures are supposed to stand vertically, but I prefer if they were designed to stand horizontally (HDs parallel to the ground), so I intend to use them in a horizontal position (HDs parallel to the ground). Is there some negative effect if I use them positioned horizontally? Or is it better if I use them positioned vertically as they were originally designed to be used? I also intend to put one 2.5" HD in one of these 3.5" external enclosures just to try if it will work OK compared to the other 3.5" HDs. I read somewhere that to use a 2.5" HD in a 3.5" external enclosure you must use a Disk Holder type C or some other type, so I guess I need to buy 1 of these Disk Holder types too if it's not possible to manually tighten and screw the 2.5" HD somehow in the 3.5" external enclosure.
