A customer has an x445 and uses the internal LSI adapter to manage two 146GB drives in the chassis.  The customer is noticing performance issues when deploying a database with significant write activity on the internal drives.  Should they consider using a ServeRAID-6M with 256MB of cache instead， and why or why not？（）

• A、Yes， the internal LSI SCSI adapter has no write cache.
• B、Yes， the internal LSI SCSI adapter is unreliable.
• C、No， the downtime to install the card and reformat the drives would be cost prohibitive.
• D、No， there will be no performance benefit， because drive performance is the bottleneck.
