AHA-1540CP
For performance, ease of use and compatibility, the AHA-1540CP family of SCSI host adapters is the ideal choice for PCs that run in today's multitasking environments. The AHA-1540CP family combines a powerful multithreaded SCSI I/O interface with a high-performance bus-mastering Direct Memory Access (DMA) architecture. The result is faster data throughput and higher overall system performance that enables you to run multiple applications.
