DELL ST3300657SS 146GB 15000RPM 3.5" SAS internal hard drive

SKU CH-3X8Y-X1QFG

146 GB 3.5" SAS internal hard drive spinning at 15000 RPM with 16 MB cache

  • 146 GB capacity stores critical server data
  • 15 000 RPM spindle delivers rapid transaction response
  • 6 Gb/s SAS interface ensures reliable host connectivity
  • 16 MB cache buffers burst I/O workloads
  • 5 inch form factor fits standard drive bays

Dell Cheetah 15K.7 146GB SAS Drive

This new 3.5 inch internal hard drive delivers 146GB of storage at 15000RPM for servers and high-performance workstations. The SAS 6Gb/s interface and 16MB cache support demanding enterprise workloads. It suits IT professionals who need reliable, fast mechanical storage for critical applications.

SAS 6Gb/s Interface Throughput

The 6Gb per second SAS link sets the maximum sustained transfer rate for this drive. Real-world throughput will be lower due to protocol overhead and the mechanical limits of the 15000RPM platters. Systems must provide a compatible SAS backplane or controller to operate the drive.

15000RPM Spindle Speed

The 15000RPM rotation speed is the primary factor determining random access latency and sustained throughput. This speed suits transaction-heavy databases and high I/O environments. Buyers needing larger capacity per drive or lower power consumption should consider alternative storage types.

Questions about this item

Is the 146GB capacity the only option for this model?

The part number ST3300657SS identifies a single 146GB capacity; other capacities carry different part numbers.

What does the 15 000 RPM spindle speed mean for real workloads?

The 15 000 RPM rotation reduces rotational latency, giving faster random access for transaction-heavy server workloads.

What does the SAS 6Gb/s interface limit in practice?

The SAS 6Gb/s link caps the host transfer rate at 6 Gbit/s, while the 16MB cache buffers bursts between the media and the bus.
