Introduction

With the announcement and release of Seagate's new 160GB 5400.3 2.5" notebook drive, which utilizes the new perpendicular magnetic recording method, we have many questions regarding the performance of these new high density platters being manufactured for an extremely critical part of our systems. Because of this introduction to the new technology, we are also wondering what the threshold is as far as the maximum density and the performance of current longitudinal recording technology.

Seagate Technology is currently the single largest manufacturer of hard disk drives with over 40% of the market share after the acquisition of Maxtor Corporation in late December 2005. Seagate has a wide range of products from desktop external storage, all the way up to serial-attached enterprise hard disk drives, with the bulk of their sales to the mainstream market being desktop hard disk drives. Their sales have boomed with the help of a handful of third party PC manufacturers and also some technology partners who use Seagate products in their own.

After our review of the 500GB 7200.9 unit, many of you kindly requested a look at the 160GB 7200.9 Barracuda drive, which featured the new high density 160GB platter. The only other drive in the 7200.9 line that features this platter is the 80GB unit, but we decided to look at the 160GB version because we had a handful of 160GB drives to which to compare performance. The 160GB 7200.9 features an 8MB buffer, a SATA 3.0GB/sec interface and, obviously, a 7,200RPM spindle speed. Take a look at how the highest capacity platter performs compared to the others.

    If you have a large, PATA backup drive, then the chance of failure issue really isn't that big a deal, especially with the longer warranties (Raptors are enterprise class products for WD, aren't they?).

    The interesting question to me is, does performance increase with 10,000 RPMs, SATA bandwidth AND increased platter density.

    I believe the Raptors aren't 3.0 GB/s SATA but they still should have plenty of room to run, and if I remember correctly, the 150 GB Raptors gained their extra space by a higher density platter than the 74 GB version.

    Now that's a setup that might be worth $600. It all depends if it lives up to the potential. AnandTech, let's get a SATA RAID-0 Shoot Out going!!
