Our customer want to work with multimedia files about 500GB and more. He is
deciding to buy storage system about 3TB.

Hi Ales.
The Max NTFS partition size and File size is supposed to be in excess of
17billion GB or 16 exabytes however that it a theoretical number because I
don't know of any Hard drives that big so as far as NTFS go's you shouldn't
have any trouble. Unfortunately its a little more complicated that just how
big your hard drive can get I know there are some problems with XP home and
hard drives bigger than 120GB which as far as I know is fixed in SP1. there
are also known issues with files bigger than 2GB specifically AVI and media
files this is dependant on the codec and what version of AVI. I know some
programs have trouble copying files larger than 2 GB. so in short NTFS can
handle the files and the storage system but I don't know about the software
he will be running on that system. it might be best to find out more about
the software he is using to produce the multimedia files

You'll hit a hardware limit long before you hit the file system limit.
A 28-bit controller can only address 128 gigabytes; 2^28 sectors * 2^9
bytes/sector / 2^30 bytes/GB. That's why some folks buying 200 GB hard
drives ran into problems. Some IDE controllers or their drivers could
be updated to support 48-bit addressing or you had to get a new
controller to support up to 128 petabytes; 2^48 sectors * 2^9
bytes/sector / 2^50 bytes/PB. NTFS can address up to 2^64 bytes, or 16
exabytes. So in perspective:
28-bit IDE controller can handle 2^37 bytes, or 128 gigabytes.
48-bit IDE controller can handle 2^57 bytes, or 131,072 terabytes, or
128 petabytes.
NTFS can handle 2^64 bytes, or 16 exabytes.
kilobyte = 2^10 = 1024 bytes
megabyte = 2^20 = 1,048,576 bytes
gigabyte = 2^30 = 1,073,741,824 bytes
terabyte = 2^40 = 1,099,511,627,776 bytes
petabyte = 2^50 = 1,125,899,906,842,624 bytes
exabyte = 2^60 = 1,152,921,504,606,846,976 bytes
The limit above is just the theoretical limit for NTFS. See
http://support.microsoft.com/default.aspx?scid=kb;en-us;325722&Product=w
in2000 where it says the actual limit is 2 TB (maybe 256 TB with larger
sized clusters). So the 48-bit controllers are more than enough to
handle NTFS for quite awhile. Western Digital makes a 250 GB IDE hard
drive, so you would need about 34 million of them to hit the current
NTFS limit.
Warn us when before you power them all up so we'll know when to expect
the next power outage.
