No one is representation particuarly right or wrong. Network speed: decimal bit/sec, 1kb/sec = 1000bit/secĬhoice of unit are purely cause by historical reasons/customs. HDD speed(SATA): decimal bit/sec, 1kb/sec = 1000bit/sec HDD speed: decimal byte/sec, 1KB/sec = 1000byte/sec HDD capacity(OS): binary byte, 1KB = 1024byte
HDD capacity(HDD OEM): decimal byte, 1KB = 1000byte RAM speed: decimal byte/sec, 1KB/SEC = 1000byte/sec RAM capacity: binary byte, 1KB = 1024byte There has always been serveral different representation systems used concurrently inside a computer: Consumer reparations is really just a side effect. The whole thing is about some greedy lawyers trying to sqeeze $$ out of HDD manufacturer. > I think that consumer protection is important, but this is a bit too overzealous… I think that consumer protection is important, but this is a bit too overzealous… It is really easy for DE developers and distributors to comply with the ways of the hard disk manufacturers simply by replacing the -h flag with -H in their graphical filemanagers and other disk utilities. On Linux, starting with fileutils-4.0, basic disk utilities such as du and df can report capacity and usage using either system: -h indicates the binary system and -H indicates the SI system. The hard disk manufacturers should not be liable for deceiving their customers, the OS vendors should bear that burden!! It’s not that customers are only getting 231 of the 250 GB they paid for, it’s that their OS is under-reporting the number of GB.
They knowingly report these quanitities in a deceiving manner. On the other hand, Microsoft and other OS vendors made an arbitrary decision to report capacity and usage based on the binary system even though it is widely known that hard disks use the SI system. However, they made their decision, and especially because it is in line with international standards, they are entitled to their decision. For the hard disk manufacturers, the binary capacity measures are an inconvenience, albeit a very small one. Hard disks are block devices, and therefore there’s no binary addressing scheme involved, unlike most RAM technologies. However, they think that the settlement wasn’t tough enough on WD, and suggest that this is a conspiracy to get people to buy more hard disks!!įirst of all, the notion that 1 GB = 1 billion bytes is actually the official SI standard. When the article started implying that they had a problem with the settlement, I thought for sure they were going to dismiss it as crap. I cannot understand how such frivilous lawsuits can be tolerated.
