Un bel link, secondo me, e riporto le parti "salienti":

Both product families feature five-year warranties, 24x7 100% duty cycle range, and Time Limited Error Recovery (TLER). TLER is a feature first introduced by Western Digital that reduces drive fallout by improving upon the communication coordination between the RAID controller and drive in handling drive errors. However, since the RE/RE2 drives expect to be connected to a RAID controller and handle error-recovery differently than the SE desktop product range, WD highly recommends against using these drives on the desktop.

Based upon the excellent performance of the RE2 drive series in the enthusiast market and the fact we have not experienced any direct issues with TLER enabled on the general desktop (although the possibility exists), we thought it might be interesting to see how these drives perform with our desktop benchmark suite. We should also note that the RE/RE2 drives carry a minimal cost penalty compared to their desktop counterparts. Whether this price difference justifies a purchase is up to the individual but the additional two year warranty, 24/7 operation rating, improved electronics, and other performance features of the RE/RE2 product seem to justify the cost in our opinion.

Throughout our intensive test schedule that has netted over 220 hours of drive testing, we did not find or experience any quality issues with this drive. While we did not experience any TLER related errors in our non-RAID tests, the possibility exists that a recoverable error could be marked as unrecoverable. However, we feel like if an error is not recovered within seven seconds then it probably is a true error and should be marked as such. It is still Western Digital's recommendation that you purchase the SE16 drive for general desktop usage although we find the RE16 to be a better overall value from a feature viewpoint. We will see shortly if it is also a better choice from a performance perspective.

Sia chiaro che sono d'accordissimo con l'apertura del thread, il dubbio è legittimo.
