菜鸟问题：这个卡是不是每通道40MB/S的？请指教

deepecho

想要买一个卡玩raid：
AMI megaraid 428 Enterprse 1200 2－channel
但不知道它的通道接口类型，是不是40MB/s。说明书里说是：

Drive interface：Fast and Wide Ultra SE (SCSI 3)

据我所知SCSI 3是20MB/s的，但同时说明书里又有这段话：

MegaRAID is a family of high performance intelligent PCI-to-SCSI host adapters　with RAID control capabilities. MegaRAID has 1, 2, or 3 SCSI channels that　support Ultra and Wide SCSI, with data transfer rates of up to 40 MBs per SCSI　channel. Each SCSI channel supports up to 15 Wide devices and up to seven
non-Wide devices.

请用过这个卡或熟悉的高手帮忙。
