Physically there’s not too much different between the black and the green, at least on the outside, and even inside the black uses the same four 500GB platters as the Green Edition.

Now WD finally brings us the first 7,200 RPM 2TB drive in the form of the Caviar Black. Western Digital is certainly counting on the continued need for mechanical hard disk drives, being the first manufacturer to produce a 2TB hard disk in the form of the disappointingly slow 5,400 RPM 2TB Green back in march. SSDs will get cheaper over time but for now at least the vast majority of us will continue to use them only as a boot disc the SSD remains very much a luxury, enthusiast product. Speeds here are two samples averaged individual drives can vary significantly.Offering capacities which SSD manufacturers can only dream of and at a cost per gigabyte of less than 10p, the hard disk drive is still the only realistic place we can store our MP3 and video collections.

The Caviar Black 2TB performs about 20% faster than the Hitachi 7K2000 for reads, and 12% faster for writes, which is a very impressive advance! However, it comes at about an 80% price premium.Īll speeds on this page freshly tested with Mac OS X 10.6.4, which appears to have improved read/write speed slightly, because the Hitachi 7K200 is testing 5-7MB/sec faster than my tests on 10.6.1 in late 2009. However, I saw no such variance with the enterprise-grade Hitachi A7K2000, which is steady at 125MB/sec. The speeds shown below are thus what I feel is accurate based on my extensive experience with them you could in theory “cherry pick” them up to about 135MB/sec. They do vary up to 10% in speed, ranging from about 120MB/sec to about 135MB/sec, averaging about 125MB/sec.

Versus Hitachi: my data storage requirements and backup needs mean that I have about twenty of the Hitachi 7K2000 drives, so I know them really well.

Testing was performed with DiskTester, part of the diglloydTools software suite, using the run-sequential command. I tested sequential read and write speed both singly and in a RAID-0 stripe.

Of course, when heavy disk seeking is happening the RE4 makes the usual seeking noise that all hard drives do, but it’s not particularly different than most drives. Nor did I hear any oddball recalibration noise as is found with some drives.

The Caviar Black is whisper quiet- I ’m not even sure I could hear them over the fan of the Mac Pro while the overnight DiskTester fill-volume test ran. I put a pair of the Caviar Black 2TB drives through their paces. The 2TB Caviar Black model (WD2001FASS-00U0B0) reviewed here costs a lot less money, so how does it stack up against the enterprise version? Reviewed just prior was the Western Digital RE4, the enterprise-grade 2TB version.
