A technician is auditing and sorting computer storage interface hardware. Match each storage interface standard on the left with its corresponding physical cabling or operational characteristic on the right.

SATA Revision 3.0Uses an internal 7-pin data connector supporting standard throughput up to $6\text{ Gbps}$
eSATAUses shielded external cabling up to $2\text{ meters}$ without supplying power to the drive
NVMe M.2Connects directly to PCI Express (PCIe) lanes for low-latency high-speed communication
SAS (Serial Attached SCSI)Enterprise drive interface whose host controllers are backward-compatible with SATA drives

Cevap

SATA Revision 3.0 matches the internal 7-pin connector supporting up to

6\text{ Gbps}

; eSATA matches shielded external cabling up to

2\text{ meters}

; NVMe M.2 matches direct connection to PCI Express (PCIe) lanes; SAS matches the enterprise interface whose controllers accept SATA drives.

SATA 3.0 uses internal 7-pin cables capped at

6\text{ Gbps}

; eSATA supports external cables up to 2 meters without power delivery; NVMe M.2 interfaces directly with PCIe lanes; SAS controllers are enterprise-grade and support SATA drives.

Adım Adım Çözüm

Identify the speed and internal cabling characteristics of SATA Revision 3.0.

SATA 3.0 employs an internal 7-pin data cable capable of

6\text{ Gbps}

transfer rates.

This is the primary standard for internal 2.5-inch and 3.5-inch consumer drives.

Identify the external drive interface specification for eSATA.

eSATA uses shielded cables up to

2\text{ meters}

for external connections without carrying power.

eSATA requires separate power cables or external power adapters for connected drives.

Determine the bus architecture utilized by high-performance NVMe M.2 drives.

NVMe M.2 solid-state drives interface directly with PCIe lanes.

Using the PCIe bus allows NVMe drives to achieve much higher transfer speeds than SATA controllers permit.

Determine the compatibility features of enterprise SAS controllers.

SAS host bus adapters support plugging in standard SATA drives.

SAS signal protocols and connector design accommodate SATA drive compatibility on SAS controllers.
