Subject:  Re: SATA kernel-buffered read VERY slow (not raid, Promise TX300 card); 2.6.23.1(vanilla)


I got my Promise card and everything is up and running without problems,
using kernel 2.6.24-rc6 and the sata_promise driver out of the box:

00:0c.0 Mass storage controller: Promise Technology, Inc. PDC40775 (SATA 300 TX2plus) (rev 02)
        Subsystem: Promise Technology, Inc. PDC40775 (SATA 300 TX2plus)
        Flags: bus master, 66MHz, medium devsel, latency 72, IRQ 17
        I/O ports at b400 [size=128]
        I/O ports at b800 [size=256]
        Memory at ef025000 (32-bit, non-prefetchable) [size=4K]
        Memory at ef000000 (32-bit, non-prefetchable) [size=128K]
        [virtual] Expansion ROM at 98020000 [disabled] [size=32K]
        Capabilities: [60] Power Management version 2
        Kernel driver in use: sata_promise

Drive is a Samsung HD321KJ 320 GB and hdparm says the drive does ~75
MB/s; with dd it does buffered writes at ~85 MB/s and reads ~295 MB/s. So
all in all I'd say it's not the card or the driver..

hth,
Holger
