SATA drive's bridge chip

Does the bridge chip installed on Maxtor, WD and IBM/Hitachi SATA drives
affect performance significantly? I didn't realize that these makes of
drives didn't natively support Serial ATA. As I believe, only Seagate does.

The answer is still the same as from the post that you got that belief from.


@drian.

not heard that. but it dont mean it's not true.

my WD has jumper section for the PATA style setup, and also has a molex
power connection - maybe a standard metal shell to the HDD though that they
used for PATA and SATA drives. as for performance, i`m running WD raptor
(10k rpm, 8mb cache, 5.3ns seek) SATA drives in RAID0 config, and getting
71mb/s according to sandra (maxtor ATA133 ran at 30mb/s for comparison -
7.2k rpm, 2mb cache).

also i did my homework on the raptor drive, and it beats alot of the
tomshardware.com tested u320 scsi drives AS A SINGLE SATA150 drive. it was
competing with the maxtor atlas 10k6 (??) U320 scsi drive.

Yes, there is an article on Extremetech's storage section about it.

Yes, that is a fast drive!

Any drive not used for backplane systems should have a Molex connector.

That is quite bad for a drive that can do near 60 MB/s on its own.

(maxtor ATA133 ran at 30mb/s for comparison - 7.2k rpm, 2mb cache).

That is appalling. A single drive can do twice that.

What Atlas 10k6? What homework?

So far as the drive, he probably means the Maxtor Atlas 10K IV, probably got
the roman numerals reversed.

Hi,

71mb/s from RAID-0 Raptors? that can't be right?. Does the array feel fast
when you use it? maybe it's just the benchmarks reprting low?
