Dell 1.8TB 10K SAS server drive
This Dell ST1800MM0159 is a new 1.8TB 2.5-inch internal hard drive spinning at 10000RPM with a 12Gbps SAS interface and 256MB cache. It ships in a lot of 10 with Gen14 caddies included for immediate installation.
Suits 14G PowerEdge bays only
The tray fits PowerEdge R340 R440 R540 R640 R740 R840 R940 R740XD R940xa R6415 R7415 R7425 C6420 servers. Builders using other generations or non-Dell chassis should look elsewhere because the caddy will not mount.
12Gbps SAS interface decides fit
Your backplane and controller must support 12Gbps SAS to use the full bandwidth. A 6Gbps-only system will work but at half speed. Verify the controller spec before purchase.

Spørgsmål om denne vare
How do I fit the GEN14 caddy into a PowerEdge R640 bay?
Slide the 2.5 inch SAS drive into the supplied GEN14 caddy until the connector seats, then insert the assembly into the hot-swap bay until the latch clicks. The step often missed is securing the caddy screw before closing the chassis.
Which part of the ST1800MM0159 will need replacement first under heavy write workloads?
The mechanical spindle and actuator arms in a 10000RPM SAS drive wear before the 256MB cache or electronics, so plan for drive replacement once SMART reallocated-sector counts rise.
What performance limit appears first during sustained sequential writes on this 12Gbps SAS drive?
The 10000RPM rotational speed caps sustained throughput well below the 12Gbps interface ceiling, so the mechanical media transfer rate becomes the bottleneck first.
