Well, IIRC the seagate also boasts of similar specs. The media to
buffer xfer rate is something like 280 Mbits/s. The interesting thing is
if you assume that the overheads (intersector gap, crc, sector framing on
the physical media) make the cost of 1 byte on media to be about 12-14
bits of physical storage - this is a guesstimate, more knowledgable people
are welcome to correct me - then the raw transfer rate works out to about
20-25 MB/s max.
And I get about 18-20 MByte/s on the samsung. Good enough, and in
typical linux way, close to the best you can theoretically get :-).
The funny thing is, I don't understand what is the point in
touting udma-66 with 66 MB/s as the peak transfer rate on the IDE bus when
there is a limit of just 2 disks per cable, and the disks are still
predominantly 5400 rpm, and on top of that you can't have multiple
simultaneous requests on the same ide channel to different devices -
making it impossible to use the available bandwidth.

Kedar.
