Is this a decent external RAID enclosure? (Raidon GR5630-WSB3)

[moviemarketing]

I need an external RAID enclosure with USB 3.0 and eSATA connections with at least 4 bays that can be configured in Raid5.

Firewire800 is nice as well.

This is the unit I'm thinking of buying:

Anyone have experience with this brand?

Any other suggestion?

Oxford 936QSE is decent RAID chip set - it capable of transfer over 200MB/sec but it lack of enhance feature as a hardware raid should have:
_ email notification
_ SMART monitoring
_ Support over 2.0TB HDD

BTW USB3.0 is slower than eSATA (3.0Gb/sec) port

I have T5-R-eSUF. Love it

On the other hand you can DIY with these two bridges:

USB3.0 to SATA bridge and


Connect USB3.0 bridge to host # 2 of SATA to SATA HW raid controller. Now you have USB3.0 and eSATA driver less 100% hardware raid
