Product Overview The external JBOD enclosure can accommodate a total of eight SATA I / II / III hard drives or SSDs. It consists largely of aluminum and is therefore stable and dissipates heat very well. The cooling of the drives is achieved due to two temperature controlled 80mm fan on the back and corresponding air-inlets support below the drive bays on the front. The door of the enclosure can be locked.

The display of the JBOD system informs through various LEDs about operation, fan, interfaces and disk usage. As a huge JBOD data storage system can provide its full function. Except the existing external interfaces USB 3.0 and eSATA the ability to use hard drives without any capacity constraints play a big role as well as .

Among the capabilities of the JBOD enclosure are various other convenient functions. Such as, for example, the strapless hard disk installation and energy-saving standby mode. As well as hot-swap capability, plug & play and support fpr both Windows and MAC systems.

For users with larger demands the ICY BOX IB-RD3680SU3 enclosure provides support of RAID Level 0 (striping) / 10/5/50 / BIG (Spanning). Features • Silent operation by thermal controlled fan
• Energy saving by supporting sleep modus!

TekSpek Guides
Date Issued: 21st Oct 2008

You've probably read the USB Tekspek, and perhaps your intrigue, or product interest, has lead you to look up Firewire as well. The two are similar in some respects, particularly some of the products that use the two technologies. However, Firewire has its differences, which means it has both benefits and drawback when compared to USB. This Tekspek will look at Firewire and also look at it with respect to USB.

8 Bay Icy Box IB-3680SU3 External JBOD Case for 8x HDD SATA 3 to USB 3.0/eSATA Host Ports is rated 4.0 out of 5 by 1.
Rated 4 out of 5 by from Great device, great throughput, bad fans. I bought this device to move a disk array out of a home media server to reduce the power drain and increase reliability and expansion capability. The box itself is attractive, with matte aluminium housing and brushed black aluminium panel and cool blue LEDs on the front control panel. The LEDs show the settings and disk access. I personally find flashing LEDs annoying and would have liked a way to switch them off, but they aren't overly bright. The silent operation is definite marketing blurb though, and the whir of the fans would irritate if you had to be in the same room as the IcyBox for any length of time. As such, it's in the hallway cupboard and neither the fans nor the LEDs bother me. Access to the disks is easy. The front panel is a lockable door (keys provided). Inside are two other doored compartments housing 4 disk trays each. These doors are secured with thumb screws. The disks themselves need a handle attaching to the front before inserting into trays in the IcyBox. Handles and screws for this are provided. This is the only part of assembly which needs a screwdriver. The disks slip easily into the trays, and the compartment door can be screwed closed after insertion. However, the door doesn't secure the disks in any way: I had one disk that I hadn't pushed in fully enough to connect to the SATA and power pins at the back of their mount, yet the door closed without a fuss and I only realised my error when the disk didn't show on the system. The SATA connection capability of the IcyBox is only SATA2, so I went with the USB3 option. Plus I didn't have an 8-way multiplexing eSATA controller. The USB3 outperformed the SATA3 controller on the motherboard, and I was very pleased with the throughput (see below for testing). The units ships with both USB3 and eSATA cables, so if your computer has the capability you can try either connection option without further expense. For the price, I think this is a very good device. There are a few small niggles as mentioned. I would liked to have connected via SATA3, as some Linux utilities are limited when the disks are hidden behind the USB controller (smartmontools and some hdparm tests can't get to the identity of the disks), but performance wasn't impacted at all. Some throughput numbers comparing USB3 to SATA3 ======================================== The purpose of testing was to check the effectiveness of USB3 versus SATA. In particular, if the USB3 would be a bottleneck. As such, the asymmetric RAID architecture/number of disks between the two systems is not a problem, but also not an accurate reflection of the SATA/USB3 capabilities. The following tests compare read and write speeds from an EXT4 filesystem on a RAID1 array of 2 disks with a ZFS filesystem on RAID10 (mirroring plus striping) of 6 disks (stripes are across 3 vdevs of 2 disk mirrors). The RAID 1 is hooked up to SATA3 ports on the motherboard, and the RAID10 is the Icy Box, connected via USB3. The system is an Intel(R) Core(TM) i5-4430 CPU @ 3.00GHz, running Gentoo Linux, kernel 4.9.6, with ZFS v0.6.5.9 All disks are Seagate BarraCuda (3TB) 3.5 inch Hard Disk Drive (7200rpm) SATA 6Gb/s 64MB, Model=ST1000DM003-1CH162 Note that all tests were performed 3 times while the server was unloaded. The output shown below is representative of the values returned, which were consistent across runs, with a variation of < 2%.

Questions & Answers

Which port multiplier technology does this use, Command-based switching or FIS-based (frame information structure)?

Asked by: JimS
Don't know - as I guess you're aware, finding any info on stuff like this is nigh on impossible. For what it's worth, I'm using it with a StarTech PEXESAT32 which is based on a Marvell 88SE9128 chip. Works just fine. [Note: ...but this card, although it has 2 x eSATA ports, only has port multiplier capability on a single port at a time. I also tried a StarTech PEXESAT322i which claims to provide port multiplier capability on 2 ports concurrently. This card is based on an ASMedia 106x chip. I had intermittent problems (logged as drive controller errors) so gave up on that one and now have 2 x PEXESAT32 cards installed, using 1 port on each to connect to 2 external enclosures. No, I'm not using RAID.] Hope this helps

How are the Drives Powered + what else is NEEDED other than the Drives?

If there was an 'Included in the Box' statement or complete Product Details this question may not have been necessary? How are the Drives Powered - Internal PSU? - Via USB3 Cables? - or? How many USB3 Cables are required, the photo is not clear enough to determine if the rear Ports are eSATA or USB3? Seems obvious that they will but don't want to waste time, please confirm that the 2.5 to 3.5 All Metal Drive Adaptor Scan # LN46274 will slot into this box. Thanks for your time, best wishes, Stan TAYLOR NB. The 'Related Products' field below could not find LN46274!
Asked by: Gelphyn
1. The disks are supported on narrow rails and plug into SATA power and data connectors on a backplane in the enclosure 2. The disks are powered from an internal power supply. A mains lead is provided 3. There are 2 rear ports, one eSATA and one USB3. Cables for both are provided. If you are using eSATA, then the controller in the PC must have port multiplier capability (because you are attaching multiple drives to one SATA port) 4. To insert and remove the disks you must attach a (somewhat flimsy) plastic handle to the front screw positions on each disk. More accurately, the handle is used to remove the disk from the SATA connectors - just move it to the 'down' position. 8 handles + 16 screws + small screwdriver are in the box. 5. Once the disks are inserted, they are held more securely in position by a metal door + thumbscrew arrangement. There are two of these, one at the top and one below, each retaining 4 disks. 6. The case door is lockable and is also held in place by a plastic clip affair. You may want to remove this (2 screws) as it is unnecessary and may require a sharp tug to open. 7. Also in the box are two (pretty useless) instruction leaflets, one in English, one in German (ICY BOX products are distributed by the German company RaidSonic Technology) 8. The enclosure is much smaller than the picture suggests - 13&quot; high x 5&quot; wide x 8.5&quot; deep. 9. What else is needed? Nothing - other than the correct ports on the PC. 10. No experience of using drive adapters in this enclosure, so I can't answer that one. The adapter would need to provide the same external dimensions as a 3.5&quot; disk, position the connectors in the right place, and be able to accept the screw-on handle... 11. Err - that's it... Hope this helps - kind regards PS: I have no connection to either Scan or RaidSonic

Is the eSATA port on this device limited to SATA2 (3Gbps)?

Asked by: JimS
Seems like it. The spec details on the RaidSonic site give the transfer rate as: USB 3.0 up to 5 Gbit/s, eSATA up to 3.0 Gbit/s Hope this helps
