Western Digital's Raptors in RAID-0: Are two drives better than one?by Anand Lal Shimpi on July 1, 2004 12:00 PM EST

Overall System Performance - WinstoneHistorically, one of the most disk bound system performance tests has been the Winstone suite, composed of two benchmarks: Business Winstone 2004 and Multimedia Content Creation 2004.
Business Winstone 2004 tests the following applications in various usage scenarios:
- Microsoft Access 2002
- Microsoft Excel 2002
- Microsoft FrontPage 2002
- Microsoft Outlook 2002
- Microsoft PowerPoint 2002
- Microsoft Project 2002
- Microsoft Word 2002
- Norton AntiVirus Professional Edition 2003
- WinZip 8.1
With only a 20% boost in pure IO performance, we weren't expecting much from the real world business performance of RAID-0 - and we weren't greeted with any surprises. Migrating to two Raptors in RAID-0 resulted in a 3.6% performance improvement; definitely not worth the added cost of a second drive as well as the decrease in reliability.
Multimedia Content Creation Winstone 2004 tests the following applications in various usage scenarios:
- Adobe® Photoshop® 7.0.1
- Adobe® Premiere® 6.50
- Macromedia® Director MX 9.0
- Macromedia® Dreamweaver MX 6.1
- Microsoft® Windows MediaTM Encoder 9 Version 9.00.00.2980
- NewTek's LightWave® 3D 7.5b
- SteinbergTM WaveLabTM 4.0f
Although we saw a bigger theoretical performance improvement with Content Creation Winstone 2004 in our IPEAK tests, the real world improvement is even smaller than in the previous test; 2.6% is the only benefit that RAID-0 will give you here.
