very poor Internal flash memory performance on new HTC devices

[fatso485]

it is very surprising that file transfer performance hasnt improved a bit in the last years. i mean it takes my xperia the same time to install a cab or to launch the same app from my 6-year-old Magican


is there something that is preventing HTC from using these crazy SLC-based 100+MB/sec flash chips found in new SSD drives. really appriciate any insite on this

Those chips aren't really that fast, they are just being run massively parallel in raid like arrays. Even still though, a setup as fast as what they use in compact flash cards would be nice.

- there are some major improvments in flash performance just take any normal flash drive (no RAID-like voodoo going on here) these days and compare it to the ones you used to have 3-4 years ago. the difference is MASSIVE even on low 1GB flash drives.

-what's wrong with running parallel flash chips in a raid-like fashion on a mobile device. it seems like one way to gain massive performance increases only

I really don't think it is the chips, it is the CRAPPY Qualcomm processors HTC uses for our expensive phones.

With the size of the chips, the price, the controller, etc... would get sort of expensive. For example, an Intel SSD looks like this. http://blog.wired.com/photos/uncategorized/2008/12/02/inside_an_ssd.jpg and costs a fortune. Their controller is the only one sofar that doesn't suck horribly at small file writes.

Look at this little glimmer of hope though :D

Too bad the a phone would probably make horrible use of it. My class 6 card might as well be a class 1 for how well my phone makes use of it.

thats exatly my point. why are $800+ 2009 devices perform identically (internal flash memory) to 2003 devices. people seem to only care about obvious things like CPU speed when hey talk about performance.
