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.

4 Bay Icy Box IB-RD3640SU3 External RAID System for 3.5" SATA HDD with USB 3.0 + eSATA Host is rated 4.0 out of 5 by 3.
Rated 2 out of 5 by from 'Icy Box' ? More like 'Toasty Box' ! Works OK as long as you leave the front door open. :( My unit worked great initially but data transfer slowed down to an unusable speed (a few Kbps) after an hour or so due to over-heating. The rear exhaust fan is more than adequate, however there is no air-intake when the front door flap is closed. After permanently removing the front door (and adding some internal baffling) the unit performed solidly. I did note thought that however hot the unit got, the fan speed did not automatically change as the documentation suggests. It can be changed manually though... The RAID configuration is simple though, all done from the front panel buttons, no setup software required. To conclude; easy to use and good value, but poor thermal design.

Rated 5 out of 5 by from Easy to set up - well built unit Purchased this unit for media storage purposes and configured it as Raid 10, using 4 x 6 TB HDD's. Seems to work well with my Dune media player and also with a laptop and desktop running Windows 10. The hibernation feature is useful as, providing the mains adaptor is always on, the unit will power up automatically when a connected computer or media player is switched on.

Questions & Answers

Can this unit be used just as extra storage?

Can I fit several drives, say 4 x 3 TB to give a total of 12TB of storage, to utilise 100% for such things as a music and/or film library, running as eSATA or USB and attached to either my main pc or laptop? I don't need a backup or mirror really just raw storage.
Asked by: Navydog
Yes you can. The controller supports RAID 0 or 'striping' but be warned that you might struggle to partition/use a single volume that size with some operating systems.

What RAID mode does this support,

I am looking to make a JBOD to act as a backup device for my home server (Server is running 4 x 2Tb disks as 2 x 2TB volumes using Windows Mirrored disks, so moderately safe'ish) I have the old 4 x 1Tb disks to back up onto, would be easier if it was a simple RAID so the 4 x 1Tb were addressable as single 4Tb space, but with 4Tb disks coming in at lower prices, I currently use a second home server as the backup device, but this could be neater and use less electricity if it works,
Asked by: Chief
This is dependent of your backup / fault tolerance requirements. The controller supports RAID 5, which would give you 3(ish) Tb with tolerance of 1 disk failure. Or, RAID 10 which will give you 2(ish) Tb with tolerance of 2 separate disk failures. If you use a single 4Tb disk, you have no fault tolerance. - I am using one of these with 4 x 2Tb drives in RAID5 to give 5 and a bit Tb usable, which works fine when now I've solved the overheating issue...

I want to use this as a backup for my Ubuntu server. I plan to configure 4x2gb disks in striped raid 0 and connect to my server over USB 3.0. Linux support is not mentioned in the documentation but I can't see why it wouldn't be supported as described above.. Please could you confirm this will work
Asked by: Sammyk
