TSUNAMI EDATAII 3500 3.5At the top end of the Tsunami 3.5" enclosure range is the TSUNAMI EDATAII 3500 3.5" External 2xHDD JBOD/RAID Enclosure.  This enclosure allows the installation of two 3.5" SATA drives and gives a range of setup options including RAID0 (Striping mode for faster disk access), RAID1 (data backup solution: one HDD acts as a backup for the other) SAFE33 and SAFE50 (1/3 or 1/5 of the drives act as RAID1 and the other portion acts as JBOD). The array of options covers pretty much any possible two drive array that anyone could require.

Installation of the drives is very straightforward and as with other Tsunami enclosuresand case, the panels are securely held in place with chrome screws which are removed using the provided allen key. The TSUNAMI EDATAII 3500 3.5" External 2xHDD JBOD/RAID Enclosure is a very well designed drive manufactured from cast aluminium, similarly to the other EDATA drives.  As with other external enclosures basic drive function can easily be monitored by an array of blue LEDs mounted on the front of the enclosure.

TSUNAMI EDATAII 3500 3.5The case is simply disassembled both top and bottom.  The HDDs are then installed into the internal metal cage, which additionally houses the insulated circuit board between the two hard drives with air gaps between for airflow and heat dissipation. There is also a switchable 40mm fan installed that can be used to blow air across the HDDs and circuitry.

Once the HDDs are correctly installed, the desired mode is selected, the enclosure turned on and the reset button held (presumably to reset the firmware).  The drive (or drives, dependent on mode) when we used the used the RAID1 function was instantly recognised in Windows XP and Windows Vista. Connection to a PC or mac is through either USB2.0 or eSATA (cables are supplied for both and an eSATA blank and connector is supplied for desktops).

We tested the GUI (graphical user interface), SteelVine_V5.1.18, which is included.  This software allows the complete management of the drive, which is especially useful for SAFE configurations (RAID1, SAFE33 and SAFE50).  The software can be configured to send email alerts should a drive fail in order that a rebuild can take place quickly and data integrity maintained.

The only drawback that we can find the Tsunami range related to the included manuals which can be a little confusing, although  Tsunami have gone a long way to rectify this by providing detailed support pages on their website.

All in al, if you are an experienced PC user, you shouldn't find any problems in installing and using the enclosureand from all aspects the hardware and software appear to be both well designed and stable.
