BlueSCSI v1 — is my performance correct?

Hello!

I’ve had a BlueSCSI v1 fitted in my SE (on System 6.0.8) for a while now, and it’s been great.

The other day, I was messing about with MacFlim to play full-screen video on that old machine. It’s surprisingly good!

However, the playback kept pausing to buffer. So I thought I’d delve into my BlueSCSI’s setup.

Using Snooper’s disk read test, I got a result of 0.15Mbyte/sec, which does seem on the slow side.

So I did three things:
  1. Reformatted the SD card as exFAT.
  2. Tried multiple branded, known-good SD cards.
  3. Flashed the latest USB-supporting bootloader onto my BluePill and upgraded to the latest BlueSCSI firmware.

Unfortunately, there was no improvement — the read test still returned 0.15MB/sec.

Now, before I go and buy a BlueSCSI v2, can anyone confirm my suspicion that this is slower than you’d expect, even on a stock 4MB Mac SE? Or, is this as good as can be expected for this machine?

Thanks!
Chris

Can you test with scsi director pro 4? IIRC a SE should be around 500k/sec on v1, and around 750k sec on v2.
