OCZ Vertex Drive: UDMA33 mode only

W

WeaponX

Hi, does anyone know what I'm missing or what I did wrong?

I have an OCZ Vertex drive but for some reason FreeBSD is unable to assign UDMA6. In the bios I have no AHCI option nor SATA150/300 selection hence I can only assign UDMA1-6 option but when I boot another OS such as linux or windows with the same motherboard, SATA300 or UDMA6 gets assigned. I've been dealing with this problem for a while now with no luck, I'm stuck at UDMA33 on FreeBSD :(

Here's are the technical details:

Problem is not in disk, but in controller. Your chipset ID seems rare and unknown to the driver. Please apply this patch and report how will it go:

Hi Mav,

Your patch worked! I'm getting UDMA5 which is much better than UDMA33!! Any idea if UDMA6 driver might get supported in the future?

Also will this patch end up in the stable branch? Many thanks!

Thank you for the report. I will commit it now and merge it down after 9.0 release.

PATA mode for SATA devices intentionally limited to UDMA5 as workaround for buggy SATA<->PATA bridges and it is irrelevant for native SATA devices. For native SATA devices (modern SATA devices) it is not important what UDMA mode is chosen. Only important is it PIO or DMA. Transfer speed limited only by SATA connection speed.

Even without this patch your drive should be as fast as with it. Difference is only in some details, such as device probe logic, hot-plug support, device reporting and so on.
 
Hi Mav,

Thanks for helping me with a patch, regarding your last post, with my ocz vertex, I'm only getting 30mb/s at 4k writes which I find it slow for what the manufacturer claims. Does this sound reasonable to you? (using UFS file system)

I did my test using:

dd if=/dev/urandom of=/cache/test400m.bin bs=1m count=400
dd if=/cache/test400m.bin of=/home/test400m.bin bs=4k
 
I would say it is indeed not much. Just two points:
- You are writing with 4k block to the file on the file system. Most likely file system aggregates writes at least to the FS block size. That should improve performance, not reduce, but it's just about correctness or your test.
- If you are using your SSD for a long time, you could already wear it. After one year use without TRIM my OCZ Vertex become MUCH slower in some cases. Now after I erasing mine, I can write about 80%-90% of it's capacity quite fast, but then speed drops significantly.

Is this still an issue with FreeBSD 9.0 RELEASE, or was the patch not necessary anymore?

Patch was committed into 9-STABLE branch on January 2, but that was after 9.0-RELEASE. Next 9.1-RELEASE will include it.
