An eX5 client is concerned about the cost-per-GB of the proposed SAS disk-based solution, and suggests using SATA disk technology in order to reduce costs for their 24x7 mission-critical Microsoft SQL Server application. Which of the following addresses the customer issues?（）
- ASAS drives support automatic rebuild upon failure, SATA must be rebuilt manually
- BSAS drives support Fibre Channel attachment to eX5 servers, SATA does not
- CSATA drives require different, more expensive cables, and require more floor space compared with SAS
- DSATA storage is slower, has lower mean time between failure, and designed for a lower duty cycle compared with SAS
