I was wondering what sort of bottlenecks to expect for 'Data Safe'

[smv1172]

I want to build as low cost as possible system that will:

-utilize a custom (but basic) touch screen GUI run in Linux.
-burn at 'max' burn speed on CD, DVD and Bluray.
-transfer large sums of data to USB2/3 device frequently and possibly bluetooth ideally at highest possible transfer rates.

for operating costs the OS/utilities will be on a small SSD, data on HDD.

Given those primary responsibilities & lack of need for general computing/games/media streaming/web browsing/etc, what bottlenecks can I expect? Most importantly involved with CPU/RAM, assuming OS can utilize multicore, will burning/data transfer/touch screen? Is more ram useful in this scenario? Ideally there should be no lag for operation and as little wait as possible for outbound transfers limited only by the delivery channel and receiving medium.

Hi

I own computer shops....this is an easy question of which you wont like the answer....

SPEED = MONEY....

In other words , you want fast anything i.e data transfer rate, its going to cost you big money...

All the best Brett

Thanks Brett, I am not so much expecting this to be cheap, just cheap as possible , so do you have suggestions on where I am going to want to drop that money to reduce hang-ups?

Like should I focus on faster proc, more cores, more RAM, yes to all of the above and are any of those more important than the others?

you need to realize that though usb3 can transmit at 480mb/s theres not many devices capable of those speeds. And for that data to come from your pc at full speed your going to need it to be on a real fast raid or ssd. Once you can acheve that - cd, dvd, BR burning wont be an issue.

Also speed of the touchscreen response is largely part of the touchscreen being used and not much to do with the pc itself. Microsoft is working on a super responsive screen technology that responds as fast as you can move. Its really nice.

Hi

Personally i would go for 15k Scsi for writing at speed and reliability....but as I said before, they are SERIOUS money....THOUSANDS for that sort of machine...

All the best Brett
