Western Digital RE4 Drives vs Western Digital AV Drives
I've been using 3GB/s RE4 drives in RAID 1 and have been happy so far. But I've recently learned of the WD AV drives designed for always on streaming. The RE4's have 64MB caches while the AV drives have a 32MB cache. The 3Ware 9550SXU controllers have their own cache.
Are these better drives for servers?
