Cool. I want.


Maybe RPM can organize one for an upcoming competition?

$800. Ouch.

So now another question, these flash memories like the USB sticks, SD and Micro SD have transfer speeds of up to 90 Mbps, SSDs with NAND flash in them have write speeds up to 550Mbps.

In the specs of a WD 500Gb standard 500Gb 7200 RPM HDD I find an internal transfer rate of 164 Mbps, so Flash memory is still slower than an old fashioned 7200 RPM spinning disc.
So no use in using them as a replacement for your HD, even as you probably have to reformat them completely differently.

Is this a stupid thought ? I am not in IT, so just a question.

I want one of these for my Macbook. Would be a nice for extra storage.

The purpose of these is not to replace your HDD, but capturing pics and video on digital camera's and video recorders. You don't need 550Mbp to dump a photo to SD card.

Yep,I know, but always interested to venture new roads. And SSDs are still a bit expensive.

Until you're shooting 12 FPS bursts and the buffer fills up

Honestly though, I'd prefer to have more speed when emptying the card to my PC.

You know what I mean

Could be very nice on my Raspberry Pi, fot the capacity, if for no other reason.

 

[mintydroid]

All the Sandisk cards I have ever owned have randomly died in use.

The raspberry will write very very slowly onto that

What's the average lifespan of such sd cards then?

 

[xera]

Ja personally I'm more interested in lifespan and reliability. In my experience, micro SD cards have been the worst, and I wouldn't trust them with anything.
