[Bug 119730] Re: Slow SATA performance

[Jonatan Magnusson]

I have the same problem:

My setup:

 * Gigabyte P35 motherboard
 * 1 WD 500G IDE drive
 * 1 Seagate 500G SATA drive

hdparm ("hdparm -tT") gives 2966/109 MB/sec (cached and buffered reads)
for the SATA-drive and 3026/74 MB/sec for the IDE-drive. No problem
there.

In Windows XP there is no problem with either drive. Both are fast
(~30-40 MB/sec).

Here are the tests I've done:

 * Reading from the IDE-drive is fast (+30 MB/sec)
 * Writing to the IDE-drive is fast (+30 MB/sec)
 * Reading from the SATA drive is SLOW (~3.5 MB/sec)
 * Writing to the SATA drive is fast (+30 MB/sec)

I've done these tests on two partitions of the SATA-drive, and using
both FAT32 and ext4.
