Seagate's Upcoming Offerings
Perpendicular recording has been in the news recently, with Toshiba bringing to the market the first drive utilizing the technology. We asked Seagate how soon it would bring a product using the new recording method to the desktop and notebook market. Back in June, Seagate introduced the 160GB Momentus 5400.3 notebook drive, the highest capacity notebook drive to date, achieved by using perpendicular recording and higher density platters for the increased disk space. The 160GB version of the 5400.3 will use two 80GB platters in combination with 4 heads to achieve this capacity. The 5400.3 line will offer 40GB, 60GB, 80GB, and 120GB as well with an 8MB cache and both PATA and SATA 1.5Gb/sec transfer rate with Native Command Queuing.
Another offering that we are looking forward to is the Momentus with FDE (Full Disc Encryption) technology. This implements a hardware-based encryption method to protect the contents on a lost or stolen drive. Since the encryption is hardware-based, there is virtually no chance of breaking into a locked volume, and in cases where the drive is to be disposed, the Disc Erase feature will completely wipe the platters clean of any sensitive data. The Momentus 5400 FDE line will come in 40GB, 60GB, 80GB, 100GB, and 120GB sizes. It will feature an 8MB cache and looks like it will be offered only in the PATA flavor - at least initially.

The best would be if they reported sound power, as sound pressure depends the enviroment, and the power is constand for a given sound source (and you can calculte the pressure at a given distance in a given room). But it's almost the pressure who is given in computer-components. And the ear "hears pressure" so for the hearing its more useful to talk about the pressure.jkostans - Monday, October 10, 2005 - link
What do HD manufacturers call 1,000,000,000 bytes a GB?ATWindsor - Monday, October 10, 2005 - link
Because the SI-system (which is centuries old), clearly defines Giga as 1 000 000 000. The fact that some software doesn't follow the standard can't be blaimed on the HD-manufactureres.rendezvous - Monday, October 10, 2005 - link
Because the SI-system (which is centuries old)Centuries as in from 1960?

The modern version of the metric system is from the 1060s, so i guess i was abit unclear, however, the metric system itself, which the SI-system is built upon is fomr the 18th century.JarredWalton - Monday, October 10, 2005 - link
Basically, the problem is that KB, MB, and later GB, TB, etc. all came from ealy computing days, where 2^10 was close enough to 1000 that they abbreviated it to KB. Later on, SI came into being and really got pissy about the use of "Kilo" for "1024" rather than "1000". The hard drive manufacturers are of course using the multiples of 1000 because it makes their product look better. Why say 93.13 GB when you can say 100 GB?SI later proposed the "kibi, mibi, gibi, etc." prefixes to get around the discrepancy. In reality, few companies are using these terms at present. That may change in the future, but in truth most people don't care. We mention this discrepancy more so that people are aware of why the difference is there than to place blame.

So you're saying windows reports "gibibytes" not gigabytes?ATWindsor - Monday, October 10, 2005 - link

So they can make smaller drives?Well, that and:

I have one 7200.7 SATA, so far no problems but seek noise is loud, I was waiting for 7800.9 to get one 500GB drive.Please make some acoustic tests when u review 7800.9.
Also with NCQ ON/Off, the 7200.7 sometimes was slower with NCQ ON.
Bench with Maxtor, WD, Hitachi and Samsung drives would be nice.
