Long-term warranty, but high price and slow
file transfer rate decreasing its scores
Western Digital Caviar Black hard disc
series is supported by a five-year warranty, which gives you peace of mind if
you are looking for a disc for storing important data; however, you will need
to remember to back up all important data, because warranty does not recover
lost files in case of failure.

Digital Caviar Black 1TB With Long
The Caviar Black 1TB disc did a slightly
bad job in the large file transfer test, with an average throughput of
124.6MB/s, which is generated by the write speed of 123.3MB/s and read speed of
125.9MB/s. They belong to the type of the slowest large file transfer speeds
we've ever seen from a SATA3 hard disc. However, the performance of the small
file transfer test proved to be slightly better, with an average transfer rate
of 58.5MB/s, write speed of 60.3MB/s and read speed of 56.7MB/s. generally,
this disc is not the best thing if high performance is your highest priority.
With 11 cents per gigabyte, this 1TB hard
disc is a bit expensive. If you are looking for a system hard disc or a cheap
1TB storage disc, then Samsung Spinpoint F3 is better, even if it only has a
SATA2 interface. Meanwhile, the Western Digital Caviar Green 2TB, even if it’s
slow and just a little bit more expensive, it gives you double capacity.

Western Digital Caviar Black 2TB With Great Performance
It’s not the cheapest 2TB hard disc,
but if you want great performance, this should be the one for you to buy.
At the moment, 2TB discs have a convenient
position between price and capacity and it is ideal for PC users who are
addicted to media, or as a system disc or data disc with a fast boot SSD. With
9.5 cents per gigabyte, the Western Digital Caviar Black 2TB disc is definitely
not the cheapest on the market, but it has a 5-year warranty and has good
performance in our file transfer performance tests.

Digital Caviar Black 2TB
In the large file transfer tests, it
created an average throughput of 133MB/s, the write speed of 135.2MB/s and the
read speed of 130.8MB/s. The average file transfer speed of 68MB/s was also
pretty good, though it did not set a record, and the write speed of 62.5MB/s
and read speed of 70.7MB/s were very fast. Generally, compared to other
competitors, Western Digital’s Caviar Black 2TB hard disc is fast.
It's not as cheap as Seagate Barracuda 2TB,
which costs only $115, or more than 4.75 cents per GB. However, the Western
Digital disc is two times faster than the Seagate Barracuda disc when
transferring small files, which makes it more suitable to be used as the system
disc. This great performance, along with the reasonable price of the disc, made
this 2TB Caviar Black the 2TB hard disc that won our Best Buy award.

Western Digital Caviar Black 4TB - Large And Superfast
Hard Disc
Large and superfast, but the high
price decreases its overall scores.
Western Digital has made 4TB hard discs at
enterprise level for a long time, but the Caviar Black 4TB aims at home users.
It comes with a five-year warranty, which you would expect if you have to spend
that much money for a hard disc.
Western
Digital Caviar Black 4TB
The performance of the disc in our test
throughput proved to be excellent, which is what you expected from a premium
SATA3 disc at the spinning speed of 7200rpm. In the large file read speed
tests, the write speed of 151MB/s and the read speed of 143.5MB/s created an
average rate of 147.3MB/s. It was very fast in the small file transfer tests
when writing data, with a speed of 88.2MB/s. However, its read speed of
53.1MB/s was slower than what we had expected, which created an average small
file transfer throughput of 70.6MB/s.
The only real competitor of Caviar Black
4TB is Hitachi’s Deskstar 7K4000. Hitachi's storage department is currently
owned by Western Digital, so more or less the company has dominated the 4TB
discs market for consumers. Although Western Digital’s 4TB disc is faster than
Hitachi’s disc, it is much more expensive. Provided that Hitachi’s Deskstar
7K4000 is not bad, it will be a better choice.
