First i will start to set the record straight that you can here very well know which device is delivered and what it can: - Read more detail either the product description of the sales page here at Amazon, - Or upon delivery to the packaging schaun where is clear that this is the Fantec QB-35US2 in black (it exists namely in white !!) is. Fantec has incidentally also a homepage "fantec.de" where you see "External housing - 3.5" enclosure - Raid systems - 4x 3.5 "raid" the various models can appearance and where performance can be found. Staff will then also that the QB 35US2 for Raid is not suitable and the higher model QB 35RFE if necessary (dominated 0/1/3/5/10 & Big) must dodge! Also found is that both models are suitable for 4x2 TB HDD. So I have procured me the model of this Amazon page, the Fantec QB-35US2 because I have no need for RAID. For me it was primarily concerned here massive movie data in any form in order to save streaming over a Popcorn Hour C-200. I must say that the equipment meets exemplary this purpose, but sequentially. The housing itself is much smaller than it looks in the pictures. Take 4 3.5 "hard disks, they either stack and it is no longer very far from the actual size of Fantec. Apart from the front door of plastic affects the device relatively sound. The front flap hangs down a just and you have to watch that when transporting the door will not simply fall down. If you switch the hard drives (which by the way very easily and quickly goes) becomes clear why Fantec has the front cover only suspended and not firmly fixed. The access to the drives is so much easier! 2 negative points should not be concealed that might annoy especially when watching films: 1) The fan is already clearly visible when the unit is close to the spectators. For me, it is, however, behind a glass door, making it silently for me and not a problem. 2) The blue LEDs are significantly überdimensionniert and brighten the dark at access occasionally the whole room. I will try this soon disconnected respectively abzukleben with electrical tape so that this issue is resolved. I have stocked the Fantec 4 Samsung EcoGreen F3 HD203WI 2TB hard drives. Accordingly, a total storage capacity of 8 TB. You can connect the device via USB or eSATA. USB is expected to represent at most no problem here all 4 disks are recognized and supported without hesitation and in full capacity. Will you connect the device via eSATA, you need an eSATA port which is Portmultiplying-capable, otherwise only the first disk is displayed. I have here in the Amazon "Adaptec RAID 1225SA eSATA RoHS Kit" card bought for this purpose the support the Portmultiplying under my operating system Windows 7 Ultimate 64bit. This requires a free PCI Express x1 slot on the motherboard. Install driver, and select when configuring the Soft "Direct Attached Storage setup" to a JBOD (Just a Bunch of Disks) and thus to ensure the simple selecting each disk to a total capacity of 8 TB. Advantage of the eSATA interface is of course up to 3 times faster compared to USB. Who therefore often move large quantities of data should allow this alternative by no means unused! In conclusion remains to say that I believe met with the Fantec QB-35US2 a good option to have. So far, the part has laid no quirks of the day and all of the settings have to prepare hingehaun bigger headache immediately and without me. I can because I herumhantiere with some material assure that the exception than the rule in Windoze universe rather ;-) Accordingly, full 5 stars for these little giants !!!
