Ive been looking to buy an External HDD. I need around 1TB of storage, id be willing to get any amount of storage between 0.750-1 TB of storage. I recently have discovered that there are many many differences that will help the I/O speed of a plattery drive. Besides the RPM of the drive i undertaand that the platter density plays a big role when it comes to transferring data and loading movies and whatnot. i Have MRoogled and Googled have came up with only a few webpages about what Platter Density is and i couldn't quite grasp the concept.!!!!! This is where all of you very intelligent members get to help me! So i think (in a very very tight nutshell) that plattery density means how (Dense, for lack of better word lol) the platter is. (god that sentence makes me sound so stupid) or like how compact the Platter is and therefore it can find stuff faster and load fater? so apparently i want a very high density platter for speed!? or do i have this entirely wrong and a dense platter means that everything is crammed together and you DO NOT want a dense platter HDD if you are looking for speed? If you are not going to read the above please read and respond to this. I only have about 300$ and i REALLY NEED an EXTERNAL HDD. NOT SSD. i need it to be very quick. im willing to sacrifice space in order for more speed (ie get a faster 800GB opposed to a slower 2 TB or something like that) ALL i want to use this drive for is games and BLU-RAY discs. i have about 90 gigs on my other external but ITS SO INCREDIBLY SLOW. Can anyone recommend for me, and everyone else out there a drive that is very very fast? Im looking for one of the fastest EXTERNAL HDDs that money can buy (within a $300 price range!) Noise doesn't bother me and if you can find me a really fast eHDD and its noise i don't care, also if it has to be plugged into the wall, again i don't care. All i want is an external HDD that i can store hundreds and hundreds on, but again i want to be very very fast so that it can transfer the movies from my external HDD to my macbook to stream on my TV, via moshi MD-->Samsung 60 inch Plasma =). I have read reviews about 10k and even 12k RPM hard drives? should i look into these? Also, this thread is for anyone and everyone that needs a one stop shop for buying quick and higher end HDDs. THanks to anyone and everyone that helps me out on this! i know im not the only one that needs a speedy HDD for the transfer of movies!!!
