BUFFALO LinkStation Pro Duo 2-Bay Diskless Enclosure High Performance Network Attached Storage (NAS) - LS-WVL/E
  • 2-Bay
  • Usage High read/write performance with RAID
  • Diskless System
  • 1 x 10/100/1000M
  • 1 x USB2.0


Compact, affordable, inexpensive, gigabit Ethernet, reasonably intuitive web-based user interface, reasonably responsive for a NAS in this price range.


The cooling fan is a CHEAP, bushing-type, and mine started clattering after only three months of 24x7 use. And, it is getting worse every day.

Worse, the manufacturer has NO replacements for sale but, according to their tech support, they would replace it under warranty if I send the entire unit back. I really do not want to incur the cost and downtime to send the unit back to get another CHEAP fan installed. Why they did not use a ball-bearing fan is beyond me (save 50-cents?).

By the way, trying to find an aftermarket replacement is turning out to be impossible - they used a fan design with UNIQUE mounting hole spacing (a Nidec D34666-67) which differs from the vast majority of 50mm X 10mm fans generally available (I can say this after spending hours looking at specs of the replacements I can find in this size, CFM, voltage, and current ratings). There is a direct ball-bearing replacement for that fan, but I have been unable to locate one for sale in the US.

I have also purchased a couple other comparable (specification-wise) 3-wire fans and modified the mounting holes, but the NAS firmware complains they are failed; evidently the tach spec in the firmware must be very specific and the speed difference triggers the failure message (an e-mail every minute!) and flashing RED LED. Not many options left at this point.

If it were not for this, I would give it 4-eggs (the NAS has other minor nits for some of the features).

Though I have generally found Buffalo products to be reliable, it is time to look for another brand of NAS.

Other Thoughts:

Takes approximately 10-hours to complete the RAID1 initialization of a 2TB mirrored pair. Also, the monthly RAID scan takes nearly as long. Not too bad considering the price range, but it may be something to consider.
