The correct answer is A. Procure a 136GB SAS interface storage device. A 15000 RPM spin speed indicates an enterprise-class hard disk, which is associated with the SAS interface - not consumer-grade interfaces like SATA, USB, or FireWire.
Question
A server technician is reviewing a server and notices the server hard disk supports up to 15000rpm. The technician is reviewing whether the hard drive can be upgraded from 40GB to 136GB for primary storage size. Given this scenario, which of the following is the technician MOST likely to do next ?
Options
- AProcure a 136GB SAS interface storage device
- BProcure a 136GB SATA interface storage device
- CProcure a 136GB USB interface storage device
- DProcure a 136GB FireWare interface storage device

Why each option
A 15000 RPM spin speed indicates an enterprise-class hard disk, which is associated with the SAS interface - not consumer-grade interfaces like SATA, USB, or FireWire.
SAS (Serial Attached SCSI) is the enterprise storage interface that supports hard drives spinning at 10000 and 15000 RPM, making it the correct interface for this high-speed drive. SATA drives are limited to 7200 RPM, so upgrading to a 136GB SAS drive is the only viable option that matches the rotational speed requirement. SAS also supports the large storage capacities needed for primary server storage.
SATA hard drives are limited to a maximum of approximately 7200 RPM and cannot support 15000 RPM operation, making SATA incompatible with this server's drive specification.
USB is an external peripheral interface designed for portable storage, not for primary internal server storage at high rotational speeds.
FireWire (IEEE 1394) is an external serial bus interface used for peripheral devices and external storage, not for high-speed internal primary server storage.
