Re: [school-discuss] Replacement Hard Drive or Computer


In Laos there are plenty of Âcomputer labs with 10 year old units... Âthey are fineÂexceptÂthe low RAM... Â I went through the same issues in Cambodia a few years back building computer labs for teacher training centers... Âat least at that time I was able to source the ram locally.. Âtoday I can't even find it... Â

why not hop a plane on over and bring a stash of parts... Â:):)

Noes, usbflash is pretty inferior in terms of performance.
Part of the problem is USB, just compare an external HDD
being plugged via (e)SATA/IEEE1394 to the same one but
plugged via USB2 (didn't look at USB3 cages yet).

I have not been so lucky to try any of the high performance USB sticks.. Â I usually just buy the cheapest one... Â In looking at the read write benchmarks of some USB sticks it sure seems to me they are up there... Â

My two 128Gb SSDs are worth every penny of ~$540 I paid for them
but that's probably another case...

nice... but way out of our price range in Laos.Â

Nice thin clients, just in case. ÂA single dualcore or quadcore
system with 2..4Gb RAM (and ideally, two SATA drives in RAID1)
would make them all feel much more modern. ÂDid you consider
some LTSP based distros? (there was a Thinstation 5.0 release
announcement recently but I didn't mess with it yet)

too complex for the staff to maintain.. Âthey currently have one Ncomputing setup and it causing troubles.Â


USB flash isn't going help those really much but an extra stick
of 64..256M SDRAM would go much further (given some lightweight
distro and a desire to run things locally).

the problem is difficulty in sourcing older RAM and of course the high price...
