LSI MegaRAID SAS 8888ELP使用的是新一代LSI SAS 1078 ROC(RAID on Chip), 內建一顆
500MHz PowerPC Processor及Hardware RAID 5 & 6 engines, 能提供Raid 0/1/5/6/50/60多種
模式, 號稱最高處理速度(Throughput)可達1.5GB/s.
而Intel新的IOP348 I/O Processor亦同樣內置了8 port的SAS控制器, 與IOP348相比, 到底誰比
較快, 實際效能又相差多少, 目前還不能確定.
LSI 8888ELP還有一個特別之處, 就是可根據自己的需要而選擇使用內置或外置的接頭. 卡上擁有
兩組內置和兩組外置的接頭, 可設定為二組外置/二組內置或是一組外置加一組內置的配撘, 彈性
相當大.
