A look at the PyPy 2.0 release
Actually I can remember that when writing to raw NAND we had also rates somewhere in the 10 to 15 MB/s range.
Optimizing Linux with cheap flash drives
Posted Feb 19, 2011 20:03 UTC (Sat) by arnd (subscriber, #8866)
* SATA is a much faster interface than SD/MMC
* NCQ and write caching allows optimizing the accesses by reordering and batching NAND flash accesses
* Using SLC NAND instead of MLC improves raw accesses
* Using multiple NAND chips in parallel gives a better combined throughput
* Expensive microcontrollers on the drive can use smarter algorithms
All of these cost money, so you don't find them on the low end drives that I analyzed.
