High-Performance, Maximum Reliability SATA 3Gb/s RAID Solution
         
SuperTrak EX8350 Highlights ◎ 8-Port Serial ATA (SATA) RAID controller with 3.0 Gb/s per port ◎ PCI-Express x 4 Host Bus Interface ◎ Support RAID levels 0, 1, 5, 6*, 10, and JBOD ◎ Linux open source driver support ◎ Online capacity expansion and RAID level migration to add capacity as needed ◎ Hardware- accelerated RAID 6 Capable for maximum reliability ◎ Intel IOP333 XScale I/O processor ◎ Multiple logical drive support ◎ Automatic/manual rebuild of hot spare drive ◎ PerfectRAID™ technology for robust error handling and recovery ◎ Battery backup module optional High Performance SATA 3Gb/s RAID Controller for Servers and Storage Systems The SuperTrak EX8350 RAID controller is a cost-effective high-performance, high-capacity solution for internal storage systems. With support for SATA 3Gb/s drives and Promise's proven RAID engine, the SuperTrak EX8350 RAID controller is designed to meet the needs of disk-to-disk backup, NAS storage, security and surveillance, video editing, and near-line storage. Enterprise-class RAID Features and Management The SuperTrak EX8350 RAID controllers include advanced RAID features for greater data protection and management. Greater than 2 TB support allows for very large arrays in 64-bit platforms. An enhanced RAID platform with advanced features such as multiple logical drive support, media patrol™, read check table and bad sector remapping protects your storage investment. Equipped with the new web-based Promise Array Manager (WebPAM™) software, SuperTrak EX8350 is extremely easy to manage for both Windows and Linux environments through a browser-based graphical user interface. SATA 3Gb/s Support The SuperTrak EX8350 controller supports SATA 3Gb/s drives and conforms to Serial ATA II, Extensions to SATA 1.0 specification with Native Command Queuing and Disk Activity LED headers support. Command Queuing increases I/O performance by intelligently reordering data requests so that data can be accessed more quickly. Supports PCI-Express for High Throughput The SuperTrak EX8350 takes advantage of the high throughput performance of the PCI-Express host bus interconnect. Using the x 4 PCI-Express bus, the controller is capable of achieving throughput of up to 1GB per second. Intelligent RAID Architecture The SuperTrak EX8350 delivers exceptional multi-drive performance by taking advantage of Intel's XScale 80333 I/O processor technology. It offers advanced RAID 6 technology for high level fault tolerance, allowing multiple simultaneous drive failures without downtime or data loss.

(드라이브 4개를 RAID 5로 묶어서) 그 당시 테스트를 돌리다가 Promise 직원들에게 제지를 받았는데 아직 테스트 버전이라 성능 측정을 말아달라고 하더군요, 쓰기 속도가 60인가... 아뭏튼 100 이하로 나왔던걸로 기억 합니다만 정식 바이오스 에서는 어떤지 모르겠습니다. 그 때 찍었던 사진 몇 개 올립니다. 결과적으로 64bit 슬롯이 없는 싱글 보드에서 저 정도의 속도가 나오니 앞으로 저렴한 워크스테이션과 영상랜더링용 시스템 구축의 길이 활짝 열릴것 같습니다.^^
