    500GB is the largest 2.5" HDD size on the market.

    The largest is a 500GB. ;)

    A 750GB and 1TB NB HDD's seem to be down the road a year or two. ;)

    WD7500KSRTL seems to be a 3.5" drive according to Newegg... are you sure you have the model right?

    I have a question about speeds. The faster the drive, the faster something loads (as long as your computer has the power to load it ASAP) right?

    if your comparing 2 of the same capacity drives then yes for example a 7200rpm 320gb hard drive would be slightly faster than a 5400rpm 320gb drive. However, a 320gb 5400rpm drive is faster than say an 80gb 7200rpm drive.

    Oh. Why? Less space should equal easier reading because the data is more spread out...

    No, this is wrong. The speed actually comes from things being crammed together really tight. Remember it is a mechanical device so the shorter distance it has to go to get the data the faster it will be.

    Lower capacity HDDs are not necessarily slower, if they are new models. For example, the 80GB version of the Hitachi 5k320 has one head reading one side of one platter and has the same performance as the 320GB version of the 5k320. I haven't seen benchmark results for that HDD but the 160GB versions of the Hitachi and Samsung 320GB HDDs have the same performance as their higher capacity siblings.

    On the other hand, 80GB in an older HDD using 2 platters and 4 heads will be relatively slow (and probably use more power).

    i thought the bigger drive the slower it is, i.e 160GB 5400RPM would be faster than 320GB 7200RPM ?

    In general, high capacity means faster data transfer since more data will reach the head during one revolution of the disc.

    There is an OCZ 250GB SSD on the shelves.

    Samsung 256GB SSDs should be out shortly. Those are the ones that would probably be the best bet. I will wait for the price to drop a bit.

    Like a lot of things, if you have to ask you don't wanna know. :D I'd guess about $800.

    Why does the memory come in powers of 2, or sums of powers of 2 (385, 768)? I mean. I understand computers function on powers of two, but does all the memory have to be like this?

    As for HDDs. 500. For SSDs, it's probably 2^8 instead of 250 :p

    You answered your own question, it's because computers run in binary.

    What I'm asking is why do HDDs come in nice, rounded-number sizes like 250, 320, 500, etc? Computers clearly function in base 2. It's all fine, but then why do SSDs come in capacities in base 2, such as 64, 128, 256, etc. Does it have something to do with the fact that a HDD is a "bulk" kind of thing, with all of its storage on one disk, and that SSDs are flash, so that they use little storage "patches" that come together to form a single drive? (not that great with terminology here xD)

    Do you think the rounded numbers on the HDD (not accounting for that 24/GB difference) are a marketing thing? Why those numbers instead of the powers of 2 like the SSD?

    Yeah, I was referring to the 256 GB SSD, which is 2^8 as opposed to the similar HDD size of 250 GBs.
