High speed USB flash stick as timeshift?

spude · 2008-06-06, 16:50

Hello,
What do you think, can you use those high speed usb sticks as a timesift folder?
(in single seat system)
eg. Kingston Technology Company - Flash Memory - DataTraveler HyperX
It says, read speed of 30MB/sec and write speed of 20MB/sec.

I know that those slower sticks wont work, but no idea about these faster ones.
And yes, I know it will consume the stick earlier

of course, i use a sandisk cruzer. works fine (single-seat setup). for sd, 4-5 MB/sec will be enough, for hd, it should at least be 10 MB/sec. mine has about 15-17 MB/sec, no problems so far.

Hi,

I thought about this yesterday while watching TV when the harddisk clicking caused by timeshifting was audible. Is 2 GB sufficient capacity for a standard setup? I think this would be six files of 256 MB each, hence leaving enough space for deletion processes. What would be the recommended size for HD timeshifting?

Regards, Johannes

With DVB-T in the UK, 2GB should be able to handle about an hour of timeshift, not too shabby.

But with the cpst of them, i'd be tempted to go a lot bigger than 2GB. An 8GB Voyager is less than £18 - Scan Computers UK: 8GB Corsair Flash Voyager, high speed USB 2.0, 10 Year Warranty

it's more likely to be Mbit than MByte

so in terms of performance there's no real need for an expensive high speed stick

I have no idea if this will work, but I'm just going to throw it out there, in case it may inspire some other ideas..

With RAM being so extremely cheap these days, you could buy extra RAM, and run a utility that makes that into a RAM-Drive, fully accessible like any other drive on your system. I use this at our office for an application that needs to run through a 2GB database daily, and the speed is roughly 80% better than a Flash disk, without the USB overhead. Better yet, you don't have it hanging out of your system and you won't burn out the flash memory :-).

There are hacks out there that let you use a RAM disk as your windows page file, so this should work easily.
