Hard Drives. Why don't they???

Question

Everything is getting more added to it. Dual , quad core processors and video cards. I know a lot about computers and how things work but have they tried to make a Dual Read and Wright Head Hard Drive.

You know the thing that goes back and forward up to 50 times a second in a hard drive. Adding two should increase the performance somehow I would imaging?

But then again besides the stats of the hard drive and hooking them up and so forth I do not know exactly how they work 100%

Maybe one read and Wright head is already more good enough as it is already.

Answer 1

first of all they would take up too much space, second of all, the seek logic of a hard drive would have to be changed, possibly along with the file system making it incompatible with any OS
sata 3g has a seek logic called nqs (native Queing sequence) which means that it can read and write ques in their natural sequaence across the disk instead of 1 per rotation which has the same multithreading effect kind of like a dual core proc, also the other guy was right about hybrid hard drives, they can have a large flash buffer that can be used kind of like ram, but for the HD paging file, and be written to without spinning up the platters, but to read they will still have to spin up, unless windows prefetch has already loaded your program into a permanent section of the paging file

Answer 2

Well I don't know about having a dual right head, but the next thing in hard drives are hybrid drives, which will have up to a GB of flash memory cache so that the hard drive does not have to be spinning all the time. This should improve performance and make the hard drive use less power. You can read more here:http://en.wikipedia.org/wiki/Hybrid_drive

Answer 3

As far as performance, you can go high end if you want, ever hear about SCSI?

Answer 4

u better go to some school & learn how to spell " read & write"

wat is wright ?

u suck
