Hitachi Unveils the Most Energy-efficient 1TB HDD
Hitachi Global Storage Technologies has rolled out its second-generation terabyte hard drive (HDD), which it claimed to be the most energy efficient 7200rpm 1TB HDD. The 3.5" Deskstar 7K1000.B consumes 43 per cent less power than its predecessor, Hitachi said. That's in part because it uses three platters, each holding up to up to 375 GB of data, rather than five, cutting the number of read/write heads from ten to six. Part of the energy-efficiency also comes from the fact that 3Gb/s SATA (SATA II) drives also use power management techniques developed for mobile hard drives.
Hitachi said the drives provide on-board automatic data encryption based on the Advanced Encryption Standard (AES)tough enough for the US government. The Deskstar 7K1000.B and an enterprise version designed for 24/7 operation, the Deskstar E7K1000, go on sale later this month priced at US $239 and US $279, respectively.

Edit-I have used hitachi drives quite a bit,in the old days hitachi drives were bad for faiilure,but not any more.When they used to fail a lot it was mostly the ibm/hitachi drives.
Maxtor drives are muuch worse,most in my experience with friends only last two years.
^^
Last time i bought a Maxtor was years ago and sure enough i did fail. they replaced it though, too bad for my data.
I RMA'd the drive but i think I ended giving it away or selling it in the end lol
theres places which sell all the decent gear - about 3-4 3storey Malls that sell nothing BUT computer hardware & other computer related goods.
hardware doesnt like when its hot n humid.
Also, the Samsung F1 1TB appears to be a very good drive in terms of speed and such but it seems to be associated with high failure rates as well which is what keeps me away from them. I would imagine it would really suck to lose a terabyte of data.
Saying that, we use WD at work and even though I'm not impressed by them, I've only seen 10 or so fail since I've been at my job (7 months).
I have two sp2504c 250's,been fine for two years now.
Considering these new Hitachi drives boast an areal density of 375GB per platter (perhaps greater than any consumer drive in the world), they are sequential read/write underperformers, when compared to the 334GB-per-platter Samsung F1 1TB and new 320GB-per-platter WD Caviar SE16.
Currently, WD Caviar SE16s seem to be the most balanced drives, in terms of price, sequential reads/writes, decibel output, heat, power consumption per platter, I/O performance, and built-in RAID optimizations/scaling. Unfortunately, however, I don't believe WD has released a 3-platter 1TB version of said drive as of yet (although they do have a slower 1TB drive not based on the new 320GB platters). So, this performance is bound to their 320GB and 640GB variants for the time being. The Samsung F1 is very fast – especially with sequential reading, but flounders in high I/O and seek scenarios – areas in which the Caviars do fairly well.
