The front air intake grill has 5 slots with which you could hardly slide in a piece of letter size paper tells you how restrictive if any air could get in.
The exhaust is less restrictive in comparison, but not much better. Using an external probe, I measured 48°C HDD surface temp on the one that is "on top" at 24°C room temp.Conclusion:
Is two better than one when you have two extra small capacity SATA hard drives sitting around after an upgrade? At a retail price of ~$70 you could get two Eagle Consus T or M series for less; especially when software operated Raid 0 does not give any speed increase over JBOD spanning or Single Drive via USB or Firewire.
It would be a different story if Raid 1 was implemented instead of Raid 0, since there is no gain in using Raid 0 for the sake of more secure data protection.PROS
Ability to use two HDDs in a single external housing
USB & Firewire connections
Software Raid 0: no speed increase, higher data loss risk.
Restricted air flow
I like to thank Eagle Tech for the review sample, and Geeks Computer Parts
for supplying us the Seagate HDDs in this review.
