It has long-term warranty, but slow
performance and is an expensive hard disc.
When you are paying for a 1TB hard drive,
you should want the best. Unfortunately, Hitachi’s Ultrastar A7K2000 does not
have a good starting point, since it uses the old SATA2 interface instead of a
modern SATA3.

Not surprisingly, as for an old SATA2 hard
drive; the A7K2000 did not seem to be very fast in our read/write speed tests.
In large file tests, it achieved the write speed of 93.2MB/s and the read speed
of 135.7MB/s, which is slightly better. Actually, the read speed is quite
comparable to that of some other SATA3 models, but the slow write speed
performance causes the average write speed for large files to drop to
114.4MB/s.
The performance in the small file transfer
tests was slower, due to the more difficult nature of the test. The A7K2000’s
write speed for small files was actually faster than that of some SATA3 drives
with 49.4MB/s, but the read speed is only 47.7MB/s, which generates an average
speed of 48.6MB/s.

write speed for small files was actually faster than that of some SATA3 drives

The price is the biggest problem for tis
hard drive, as 8p per gigabyte is not enough to compete. Given that this hard
drive uses an old technology, that price is too hard to justify, even if it
includes a five-year warranty. Samsung’s 1TB Spinpoint F3 is faster and has
better values.

Hitachi Deskstar 7K4000 4TB – Perfect Disk with Much Space
It’s fast, large and of great value,
which makes it the perfect disc if you need much space.
Hitachi's storage department was acquired
by Western Digital, but it still remains independent. That's good news because
Hitachi’s Deskstar 7K4000 4TB is the best high-capacity hard disc currently.

If you install the disc on the PC, Windows
will split it into two NTFS partitions including 2,048 GB and 1,678 GB. If you
are running other operating systems, such as Linux, or installing the disc in
the NAS, other file systems will be able to handle the entire disc as a single
one.
Of course, this SATA3 disc is fast, with
the write speed of 149.3MB/s and the read speed of 160.4MB/s in the large file
transfer tests, which generated an average speed of 154.8MB/s. While small file
transfer performance was not very impressive, at only 32.4MB/s, the read speed
for small files is 71.7MB/s, which helps it achieve a total average for small
files of 52MB/s.
Hitachi Deskstar 7K4000 4TB is one of the
fastest hard discs we've ever seen; its small file processing was somewhat
inconsistent.
Although the Deskstar 7L4000 4TB outdid in
the large file transfer tests, which suggests that it is one of the fastest
hard discs we've ever seen, its small file processing was somewhat
inconsistent. However, with only 6.5 cents per gigabyte, it can’t be denied
that this hard disc is of great value. You also have a five-year warranty, so
the Deskstar 7K4000 4TB won a Best Buy award.
