SeriTek/1eVE4 4-Port 1.5Gb/s eSATA PCI / PCI-X Host Adapter

Up to 4 SATA devices | Fully Bootable
The SeriTek/1eVE4 Host Adapter provides an easy and affordable way for Macintosh users to add inexpensive, high-speed storage. With four external shielded eSATA Serial ATA ports, each offering 1.5Gbits/sec performance, the SeriTek/1eVE4 provides the high bandwidth to meet the needs of performance-hungry applications. The SeriTek/1eVE4 is PCI-X compatible, permitting Power Mac G5 users to take advantage of the latest extended PCI technology while maintaining backward compatibility with older Power Macintosh systems.
  • Latest external eSATA ports with hot-swap capability; supports hot-swapping of independent and RAID volumes
  • Plug-and-Play ease of use
  • Completely self-contained booting functionality, no driver installation necessary
  • Boosts overall system performance with per-port data transfer rates of up to 150MBytes/sec or 1.5Gbits/sec
  • Supports Power Mac G5 PCI-X (Peripheral Component Interconnect Extended) bus
  • Compatible with all PCI-based Power PC Macintosh computers
  • Supports Mac OS 9, and OS X version 10.1.5 or later
  • Provides performance and protection: Supports native OS X RAID 0/1; OS 9 RAID with 3rd party software
  • User-upgradeable firmware
  • 48-bit LBA support for drive sizes larger than 137GB
  • Perfect for upgrading and expanding legacy and G5 Macintosh computers
  • PCI-X 1.0a compliant 64-bit at 133/100/66MHz bus speeds
  • Backward compatible with standard 32/64-bit PCI at 33MHz and 66MHz bus speeds
  • Direct Port Access: Enhanced performance by allowing data transfer to all four drives simultaneously
  • Bus master operation enhances multitasking during disk transfers and increases CPU efficiency: The CPU is free to handle other tasks during data transfers between the PCI Bus and system memory
  • Data protection: Supports OS X RAID, OS 9 Software RAID (third party software), and other storage utilities
  • Reduced setting on storage devices (no master/slave) means easier installation and replacement
  • Ideal for a variety of Power Macintosh applications: Desktop publishing, Audio/Video storage and editing, photo/graphics storage and editing, servers, and gaming

  1. IDE to Serial ATA converter module required for Parallel ATA and Ultra ATA133/100/66 drives
  2. Early Hitachi Serial ATA hard drives are incompatible with the SeriTek/1V4 Host Adapter. This is due to a seldom-used Serial ATA feature called SSC, which is enabled on these hard drives. The SeriTek/1V4 does not support this feature. Newer model Hitachi Serial ATA hard drives should be compatible with SeriTek/1V4.
  3. At this time, the following Hitachi Deskstar hard drives have the SSC feature disabled, and are compatible with the SeriTek/1V4 host adapter:
    • Model 7K400 (400GB) - Part Numbers 0A30984 and 0A30985
    • Model 7K250 (250GB) - Part Number 0A30340
    • Model 7K250 (160GB) - Part Number 0A30339
    • Model 7K250 (120GB) - Part Number 0A30338
    • Model 7K250 (80GB) - Part Number 0A30337
    • All of the Hitachi SATA drives offered by OWC comply with this SSC specification.
    Other Serial ATA hard drives from manufacturers such as Maxtor, Seagate, and Western Digital do not have this feature enabled by default and are therefore compatible.
