portable hard drive 640gb image
Bikash
I bought a Western Digital portable external hard drive of 640 GB. But once after I plug in my lap top it just shows 596 GB(with NTFS partition). I lost almost 44 GB. It makes me too disaapointed. Is there any way I can get all the 640GB space?
Answer
No...
640Gb = 640000000000 bytes
1 Kb = 1024 bytes
1 mb = 1024 kb
1 gb = 1024 mb
Therefore: 640000000000000/1024/1024/1024 = 596GB
They write it differently in the shop to make more money.

How are you defining "portable"? I've seen USB NAS setups (Network Attached Storage) with the possibility of RAIDing multiple terrabyte hard drives together, for a reported supported capacity of over 32TB. If you need that much space and not running a large company, you have some issues...those typically run upwards of $400. They are relatively portable, in that they have handles and can be picked up and moved, but not like thrown in a backpack or something. They are about the size of a briefcase or small suitcase.
Next step down (in physical size): raided 1.5TB drives (total 3TB). These are still about shoebox sized. They run about $250 or so. Still kinda big and heavy, but would fit in a backpack if needed.
Next step down: Standard external 3.5" drive, like a MyBook. 1.5TB. These run about $180-200. They are about the size of a moderate hard cover book.
Next step down: Standard 2.5" external drive, 640GB. These run about $150-200 at this size, depending on what other connectors you want on it. About the size of a small paperback.
Next step down in size: External 1.8" solid state drive. Largest I've seen is 256GB, but at a whopping price tag of over $1000 for one this large. About the size of a credit card.
Next step down in size: USB drive/Thumb Drive/Jump drive/etc. Biggest I've seen is 32GB (before going to 1.8" solid state drive), but one that large will run about $150-300. You can get smaller ones for much less. Slightly smaller than your thumb.
Next step down: MicroSD Card. About the size of a pinky fingernail. Max size I've seen is 8GB. However, this is not usb unless you have a media reader built in (which is technically always USB anyway).
