For this you would get a 0.004-GHz 8-bit processor with 0.064 Mbytes of RAM, a 12-inch monochrome text-only display, a 0.16-Mbyte floppy drive, and no possibility of a hard drive. Compare that with a PC purchase to...

متن کاملFlashing up the storage hierarchy
The focus of this thesis is on systems that employ both flash and magnetic disks as storage media. Considering the widely disparate I/O costs of flash disks currently on the market, our approach is a cost-aware one: we explore techniques that exploit the I/O costs of the underlying storage devices to improve I/O performance. We also study the asymmetric I/O properties of magnetic and flash disk...
متن کاملFlashing up the storage layer
In the near future, commodity hardware is expected to incorporate both flash and magnetic disks. In this paper we study how the storage layer of a database system can benefit from the presence of both kinds of disk. We propose using the flash and the magnetic disk at the same level of the memory hierarchy and placing a data page to only one of these disks according to the workload of the page. ...
