I'm developing an asterisk based PBX on a TRASCEND DOM (ssd).
At boot all seems slow, but since Linux kernels use higly buffered
read/write operations, i will not have problems at all.
But, consider to:
1. Use many many RAM. Astersik use few RAM but huge RAM is needed for
disk buffers.
2. Screw the system and avoid all unnecessary writes on disk: logs,
db, recordings, etc.
3. Do NOT use a journaled filesystem: i use ext2
3. Avoid swap (see 1)
Bye.

M bits/sec or bytes/sec?
If bytes, then that's a fast device! If bits, then it's about right.

The easy answer is to not run directly off the flash, but to unload the
flash into RAM and run from a ramdisk. This is what I do in my systems -
boot off flash into RAM, then everything runs in RAM.
Except a separate partition for voicemail.
Eg:
Filesystem Size Used Avail Use% Mounted on
/dev/ram0 136M 105M 32M 77% /
tmpfs 244M 0 244M 0% /dev/shm
/dev/hda3 64M 1.9M 63M 3% /data
Even if you're running "live" out of flash, it'll be fine as Linux will
buffer everything up in RAM anyway, so you might have a 'hit' the first
time round (unlikely though), but after that it ought to stay in RAM if
you've got enough.

I'd suggest rolling your own rather than running directly off flash
though.

25mb/sec isn't too bad it depends on how busy the system is.
You could place most read prompts in to a ramdisk, however, the Linux kernel
will cache frequently read files anyways...

Hi !
We are running our asterisk from a transcend ts8gifd25. The whole system, including the OS fit in this 8 gig disk. If you don't do any recording of calls, you don't need that much of speed.
We have 20 or so SIP phones, a PRI trough a quad-port sangoma card, one other port is a "pass-trough" to a dial-up RAS, another port is a point-to-point T1 data link to our office.
To date, we've handle a handfull of simultaniously calls without any performance degradation.
Regards,
