2009-04-16 12:49:08     pata-bf54x + CompactFlash write speed low

Vlad Shakhov (BELARUS)

Message: 72764   

On our custom board, based on BF548, I use the CompactFlash connected directly to IDE (ATAPI)

I have 2 CF Transcend cards - old 80x (PIO4) 1GB and brand new 16GB 300x (UDMA4) TS16GBCF300.

Read speed: 4MB/sec for old, 10MB/sec for new card

Write speed: 3Mb/sec for old, 1.8 MB/sec for new

Speed test perfomed as "time dd if=/dev/zero of=/mnt/test bs=1M count=128"

Switching to  PIO (bfin_atapi_mode=p) result the small write speed decrease (10-15%).

Testing the TS16GBCF300 outside bf548 show, that it's not the TS16GBCF300 problem (even on slow USB 2.0 card reader it perform 4MB/sec on Write)

Compare to another CF card and Toshiba Disk Drive (MK4032GAX)

Totally 3 devices benchmarked on our custom board:

1) 16 GB Transcend CF UDMA/66 300x card - 1.8mb/sec write

2) 1 GB Transcend CF PIO4/80x card - 3.0 mb/sec write

3) 40 GB Toshiba disk drive UDMA/66 - 10 mb/sec write

Target device is the 1) device.

There was also some benchmarking outside of bf548 board. It show that 16GB card can write much more fast.

And it's seem to be a some kind of BF548 or pata-bf54x regression, not the Transcend CF defect.

Could you try to test again through USB card reader on bf548. Is that much faster?

At last I got the benchmarks:

Write speed via USB Card Reader is:

    5.1 mb/sec for 16GB CF (UDMA, 300x)

    4.6 mb/sec for 1GB CF (PIO4, 80x)

It's 2.8x times faster ( 1.8mb/sec with direct connect) than directly via ATAPI for target 16GB CF card.

Also need mention that 1GB CF (PIO4) card is 1.5x times faster via USB CardReader.
