There have been tested 5 hard drives using different tests (mainly
surface access times tests):
1. Samsung HD204UI in Verbatim 2 TB 3.0 USB enclosure.
2. Samsung SP1614N
3. WDC WD6400AAKS
4. WDC WD1600BEVS
5. Seagate ST320410A
The tests results are in 149 files of the screenshots of these tests,
available to download in this thread:
1. Generally Samsung drives (even the new 2TB Samsung HD204UI) seem to
have considerably poorer quality of the surface comparing to the 3 years
old (or so) Western Digital WDC WD6400AAKS.
2. I would like to see similar tests, in particular of other brands and
models of 2 TB hard drives. Please upload your tests results in that
thread (click the link above).
3. I wonder why in some hard drives slower access times can bee seen
aligning in some diagonal patterns (in HD204UI) and why in some other
drives (in WDC WD1600BEVS) a checkered pattern appears (only from the
second half of the scan) which "shape" changes regularly depending on the
part of the disk surface scanned, while in some other drives no such
regular patterns are present?
4. Why is there such a difference in SMART status health notification
between various software for Samsung SP1614N (it is red for most of the
tests in HDD Health and everything OK in HD Tune)? There is also a
significant difference in MHDD scan result and HDDScan result for
5. BTW, it took ca. 31 h to test Samsung HD204UI in Verbatim 2 TB 3.0 USB
enclosure on USB 2.0 port.
