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.

and i just bought a 400GB Seagate... oh well.Live - Monday, October 10, 2005 - link
The sound info from Seagate is so obvious bull. And also the comments regretfully often found here @ AT:A sound being drowned out does not make it silent. And assuming that everybody uses 8 delta case fans at full speed and thus does not care about the sound from hard drives, PSUs and graphic cards is just plain stupid in my opinion. With today’s water cooling and heat pipe technologies a lot of people are turning to the silent side. A hard drive in my system is one of the noisiest components.
Don’t know what I am commenting tough, I thought I clicked an article but it turned out to be nothing more then an advert. Leave this kind of info for the news section and be an independent hardware site that you usually do so well.

Well thats somewhat obvious, and my experience with Seagate dictates they havent been as quiet as the old Barracuda IV was. Those drives *were* basically silent, you could almost never hear them... even if they were under load.andyc - Monday, October 10, 2005 - link
How would the Seagate's new line compare with the Western Digital's:"Western Digital Caviar RE2 400GB 7200RPM SATA 16MB 8.7"
"Western Digital Caviar SE16 400GB 7200RPM SATA 16MB 8.9MS"
"Western Digital Caviar SE16 250GB 7200RPM SATA2 16MB 8.9MS"
I've had nothing but good experiences with Western Digital...but I might turn over to Seagate if they turn out to be more superb.

The Seagate line I think matches the Western Digital line very well.
It has less platters at 400GB capacity, 3x133 Design vs WD 4x100 design and less platters at 250GB 2x125 vs WD 3x83. Seagate has SATA2 from 80GB-500GB, where WD is limited to 120GB to 250GB for their SATA2 drives, only downfall is that to get the 16MB buffer is only available at 300GB & higher for Seagate, where WD has a single model SATA2 drive with 16MB Buffer the 250GB model, the other 120GB to 250GB drives are like Seagate limited to 8MB buffer. Seagates 80GB to 250GB for 8MB is competitive. Plus seektime is 8.5ms. Plus for Seagate their drives get a 5 Year Warranty, not like WD which only get 5 Years on it's RE and Raptors lines I believe and 3 Years on the rest.

Is the Seagate 7200.9 16MB 300GB 3x100 or 2x150 with the advent of 160GB Platter technology from Seagate.

If you look at the table of specs, you'll notice the 300GB has the same wattage as the smaller models including the 1 platter(12.4/12.8/7.2 watts). Also it's got the same acoustics as the smaller models of 2.5 idle and 2.8 seek. The larger 400/500 models have slightly higher wattage and 2.8 idle/3.2 seek. This leads me to strongly believe that the 300GB model is also a 2 platter design using 150GB a platter...and is therefore slightly short stroked on a 160GB platter. I hope I'm proven right, because assuming it's a reasonably quiet drive...it's definitely the one I WANT! Looks like a candidate for the best drive with the features of quiet, a decent amount of storage, SATA 2.5 and a 5 year warranty!coldpower27 - Tuesday, October 11, 2005 - link
Yeah I hope so to, I am so far fond of the 2 platter design drives. I don't really want to a larger number of platters if unecessary.JarredWalton - Monday, October 10, 2005 - link
I believe it's 3x100GB. It might also be 3x133, but only using five heads (i.e. 2.5 platters). Actually, 5 heads seems more likely, but I don't know for sure.There are a few specific platter sizes that are common. Right now, those are (as far as I know):
60GB (old and on the way out, if not gone already)
80GB (fading fast)
100GB (still in production, but diminishing over time)
120/125GB (Relatively new; different brands might go one way or the other)
133GB (only a slight bump from 120/125, really - still new. Some "failed" platters might be formatted for 120/125GB)
160GB (brand new starting with certain Seagate 7200.9)
There is variance to a degree within those sizes. I think some of the 250GB drives, for example, use 133GB platters that are downgraded to 125GB capacity.

why don't some hdd maker sticks 2-3gb of flash memory to a 200gb something hdd.i don't even have to list the possibilities of such a solution, do i?
