Re: SATA disk detected as IDE? SOLVED
Hello Amrit. One option of the BIOS of the motherboard was allowing use with much less speed, I don't understand how much how run this, because install XP CD don't detect any SATA disk but Linux treat disk as IDE, and now seems that runs really much more fast, more than twice.

Why do you say that it is detected as IDE. Normally IDE disks using deprecated IDE driver are shown as hda, hdb etc. where as SATA and the same IDE disks with newer PATA driver are shown as sda, sdb etc. For you it is showing the disk as sda. Take a look at "lspci -k" to see which kernel driver is getting used. Also a very easy method to see the reading speed of the disk is dd if=/dev/sda of=/dev/null bs=1M count=1024 This will read the first 1024MB of your disk. I think a good disk/controller gives you more than 70MB per second or so.

I think a good > disk/controller gives you more than 70MB per second or so. That depends on many factors, the big one being whether the drive and controller both support NCQ, and if they both have a good implementation of it. Look at the ATA_NCQ_HORKAGE list to see a group of drives whose performance _drops_ considerably with NCQ enabled, or suffer other more serious problems with NCQ enabled such as filesystem corruption, data loss, etc. Other factors affecting sequential read performance (dd) are the elevator used, and the nr_requests and read_ahead_kb settings. Bumping read_ahead_kb up from the default 128 to 512 or 1024 will produce a decent increase in sequential read performance, about 10-20%. For example, a quick test on one of my lower end systems produces a 16% increase in sequential read performance: /$ dd if=/dev/sda of=/dev/null bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 16.8026 s, 63.9 MB/s /$ echo 1024 > read_ahead_kb /$ dd if=/dev/sda of=/dev/null bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 14.4375 s, 74.4 MB/s (This system only has only 384MB RAM so little to none of the performance increase was due to buffers/cache from the first dd run) _But_ a high read_ahead_kb setting causes a huge rise in the size of kernel I/O buffers, eating system memory like candy. This one test caused a 6 fold increase in my kernel buffer size, to over 260MB. Playing with read_ahead_kb for testing can be useful in measuring absolute hardware performance, but I wouldn't run day-to-day with a setting much higher than the default. There are some specific server applications where high read_ahead_kb is useful, such as streaming media servers, but they are few and far between. -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".

ATA_HORKAGE_NONCQ isn't new to 2.6.33. I don't know how long it's been
around, but it does go back quite a ways in 2.6.x. Here it is in 2.6.31.1,
which is the oldest source I have sitting around.
