Hye Guys. want your opinion on hdd i want to buy. I read reviews that WD green is using only low consumption on power so good to save energy..n..
1- Is WD green 5400rpm 1tb is sufficient enough to store and watch movies/anime?
2- Any side effect if using green WD for running OS / heavy games?
Should be fine. I'm using 6x 1TB WD Caviar Green (most as data drives for audio/video storage, one as a OS drive) - no issues with it at all. My rigs run 24/7 folding.1- Is WD green 5400rpm 1tb is sufficient enough to store and watch movies/anime?

I just bought a transcend storejet 320GB portable hard drive but when i check the capacity after plugged in to my pc it only states 298GB.
Is this normal? where are the balance capacity?
Yes that's normal. It's all a matter of how you define 1MB as. HD manufacturers define 1GB = 1000MB, and 1MB = 1000KB, etc.. but operating systems like Windows use a different definition 1TB = 1024GB, 1GB = 1024MB (because computers are essentially binary machines, everything has to be a power of 2). In addition, once a disk is formatted, some space will be reserved for the OS to use.Is this normal? where are the balance capacity?

Capacity measurements
Raw unformatted capacity of a hard disk drive is usually quoted with SI prefixes (metric system prefixes), incrementing by powers of 1000; today that usually means Gigabytes (GB) and Terabytes(TB). This is conventional for data speeds and memory sizes which are not inherently manufactured in power of two sizes, as RAM and Flash memory are. Hard disks by contrast have no inherent binary size as capacity is determined by number of heads, tracks and sectors.
This can cause some confusion because some operating systems may report the formatted capacity of a hard drive using binary prefix units which increment by powers of 1024; today that would be Gibibytes (GiB) and Tebibytes (TiB). To make matters more confusing, these reports may be mislabeled as GB and TB rather than GiB and TiB.
A one Terabyte (1 TB) disk drive would be expected to hold around 1 trillion bytes (1,000,000,000,000) or 1000 GB; and indeed most 1 TB hard drives will contain slightly more than this number. However some Operating System utilities would report this correctly as around 931 GiB or 953,674 MiB, although the report might be incorrectly displayed as 931 GB or 953,674 MB, using the wrong labels. (The actual number for a formatted capacity will be somewhat smaller still, depending on the file system). The following are all correct, if possibly confusing, ways of reporting one Terabyte.
SI prefixs (Hard Drive) equivalent Binary prefixes (OS) equivalent
1 TB (Terabytes) 1 * (1000 * 1000 * 1000 * 1000) 0.9095 TiB (Tebibytes) 0.9095 * (1024 * 1024 * 1024 * 1024)
1000 GB (Gigabytes) 1000 * (1000 * 1000 * 1000) 931.3 GiB (Gibibytes) 931.3 * (1024 * 1024 * 1024)
