750GB/1TB hard drive

I am looking for a hard drive, must satisfy:








-worth it for the price








I'm really looking for a steal for the 1TB :thumbsdown_anim: but I'll be happy with 750GB.


I mean, why do I need this?


ANSWER: I have a 160GB right now.   You know what that means.  It also has a crappy 8MB cache, is one of the budget WD models, and scores really low on Sandra, Geekbench,...

I recently purchased a Samsung 750GB Spinpoint HDD for my HTPC hackintosh. It is very quiet and very fast (it out-performs and is quieter than my WD 320GB AAKS, and Segate 320GB 7200 HDD).


The 750Gb model cost around $180 on newegg. I also wanted a 1TB drive but could justify paying an extra $100 for 250GB of space.


Something to note - i install Leopard on this drive using the GUID partition table. Leopard Partition: 150 GB, Storage Partition: 550 GB, which totals 700GB. (not 750GB!?). I think it has something to do with a kilobyte = 1024 bytes, and not 1000 bytes. (So the HD is marketed as 750GB (based on a 1000 byte kilobyte) but the OS allocated at 1024 bytes per kilobyte -- i havent done the math but 50Gb seems like a lot to give up due to this conversion).

Technically, they didn't like to you. It is your OS that is lying to you. 1 kb = 1000 bytes, 1 mb = 1000 kb, 1 gb = 1000mb, etc.

The 1024 notation is actually slightly different. 1 KiB = 1024 bytes. 1 MiB = 1024 KiB, 1 GiB = 1024 MiB. Which is the unit that operating systems uses, because well powers of 2 are easier for binary.

So 1 GB = 10^9 bytes. 1 GiB = 2^30 bytes. So 1 GB = 0.931322574615478515625 GiB. Multiply that by 750 and you get approximately 698 GiB. Which makes sense. You're not losing any data. It is just 2 different Units.


Hardware Companies prefer to use metric units. They are engineers. Engineers will tell you stick non SI units up your ... you know where. Everything else they do is in metric and they deal with a lot more complicated math, so I would say that it makes sense.

The Software world has always tried to stick to the binary notion and powers of 2. if you look at it closely. 1 KiB = 2^10, 1 MiB=2^20, 1 GiB=2^30, so there is a metric like similarity, but it is a different unit and this disparity is due to the change in units.


Unfortunately software in general likes to call GiBs GBs, so people think that hardware companies are jipping them GBs when its the software company that is misinforming them. Lots of programs do make the distinction between the metric and binary units, but most of them are network programs.
