WD Caviar Black high performance 3.5-inch SATA hard drives combine 7200 RPM spin speed, 32 MB or 64 MB cache, SATA 3 Gb/s interface, and up to 2 TB capacity for the ultimate in power computing. High Performance Electronics Architecture: Dual processor – Twice the processing power to maximize performance. Colossal cache – Bigger, faster cache of up to 64 MB means faster performance. Rock Solid Mechanical Architecture: Dual actuator technology – A head positioning system with two actuators that improves positional accuracy over the data track(s). The primary actuator provides coarse displacement using conventional electromagnetic actuator principles. The secondary actuator uses piezoelectric motion to fine tune the head positioning to a higher degree of accuracy. StableTrac – The motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking, during read and write operations. NoTouch ramp load technology – The recording head never touches the disk media ensuring significantly less wear to the recording head and media as well as better drive protection in transit. Massive Capacity – WD Caviar Black SATA drives are available in capacities up to 2 TB. Compatible – We perform tests on hundreds of systems and a multitude of platforms in our FIT Lab and Mobile Compatibility Lab to give our customers confidence that our drives will work in their systems.

I gave it a try and bought 2 of them. They seemed good for 2-3 months, then I started to get SMART monitoring errors...hrm, ok well, they were in a s/w raid1 array and western digital claims the drives should not be placed in any raid configuration.
OK - reconfigure the drives to run as single units and follow best practices/etc. Drive 1 dies a few weeks later. WD replaces it easily with a newer version w/ a much higher serial number (the original was very low so I might have gotten some of the first production batches).
That drive is now running fine, w/o any real issues, although the SMART load_cycle_count has been increasing faster than it should which could be fixed for most controllers, but not w/ the 3ware JBOD controller I'm using. Hrm...well, it might fail a few years down the line and I'll deal with it then. WD does have a 5yr warranty.
Drive 2 fails about 6 months after purchase. Monitoring picks up huge numbers of offline uncorrectable errors. This drive also had a very low serial number so it could have been suffering initial production problems. RMA'd easily. However, WDC sent out a "recertified" drive with a modestly low serial number and this drive is reporting errors within days of install.
I have 5 of the WDC enterprise RE4 drives installed for ~6months w/o any issues (smart reports show wonderful health) and the only drives I've had issues with are the caviar blacks which are tending towards 150% failure rate... I'm going to try upgrading the SATA cable of the current problematic drive.
Going forward, for WDC SATA, I'll only be buying the RE4's. No more caviar black.
While not specifically supporting RAID configurations they have had very few false array failures from extended error recovery time. This too speaks to their reliability.
The black line drives seem to be somewhat more noisy than the green and blue line drives. This isn't a problem for my clients as their PC's tend to be under their desks and that muffles any drive clicking enough.
Today when I have clients who need faster performance than conventional drives like these provide I'll move them toward a SSD drive. If you want the conventional drive economy the WD Black line should be a good choice.
Do better next time plz..
I purchased these drives to increase the storage space in my home office media server (Dell PowerEdge, 3.0Ghz HT, 2 GB DDR2 RAM, PCI/e SATA II RAID controller). Before selecting a final RAID configuration I did extensive testing of these drives to determine read performance (write isn't that much of an issue when streaming video and music to various locations) and here are the results of those tests.
The "control" group was the PowerEdge's two 360GB WD green drives configured in RAID 1 (disk mirroring) (the OS drive is a pair of EIDE 10GB drives in RAID 1). These results are the average of four passes with HD Tune.
RAID/Space/Max Read (MB/s)/AVG Read (MB/s)/CPU
1 / 360GB / 99.6 / 76 / 2.1%
1TB WD Black drives
RAID/Space/Max Read (MB/s)/AVG Read (MB/s)/CPU
0 / 4 TB / 205.3 /168.8 / 6.1%
1 / 2 TB / 108.6 / 86.3 / 2.9%
0-1 / 2 TB / 207.3 /168.6 / 6.5%
5 / 3 TB / 233.0 / 205.9 / 8.6%
Comparing "apples to apples" in a RAID 1 configuration the 1TB WD Black drives are noticeably faster than the smaller Green drives. I was rather surprised that the RAID 5 configuration scored so much faster than the RAID 0-1 configuration and in the end I went with the RAID5 configuration as it gave me the best "bang for the buck" (reliability, speed, and available space).
Prior to implementing RAID5 with these drives on the server the average transfer rate from the WD Green drives to my laptop via 802.11g router was 1.8MB/s (this was tested using large audio and media files). With that same router I am now seeing 4.6MB/s (roughly 42Mbs), which is near enough to the theoretical limit of 54Mbs on the router that I suspect the reason it isn't faster are due to limitations of the router. Doing hardwired tests (plugging the laptop into the 100Mbs ports on the router via a network cable) would seem to confirm this as the transfer rate improved from 1.9MB/s to 10.3MB/s.
