SKU CH-46KW-YP21C

1.8 TB SAS hard drive spins at 10,000 RPM with a 128 MB buffer and includes a 2.5 inch system caddy

  • 8 TB capacity stores large server workloads
  • 10000 RPM spindle delivers fast data access
  • 12 Gbps SAS interface provides high throughput
  • 128 MB cache buffers burst I/O efficiently
  • Includes IBM system caddy for direct installation

1.8 TB 10 000 RPM SAS Drive

The IBM HUC101818CS4200 is a 2.5 inch internal hard drive built for servers and storage arrays that demand high throughput. Its 10 000 RPM spindle and 12 Gbps SAS interface suit transactional workloads and mixed read-write environments.

Included IBM System Caddy

A matching IBM system caddy ships with the drive so it slides directly into compatible hot-swap bays without extra hardware. The 128 MB buffer helps smooth burst I/O while the SAS link maintains dual-port redundancy.

2.5 Inch Form Factor Build

The compact 2.5 inch chassis fits dense enclosures and blade chassis where 3.5 inch drives cannot. Standard SAS connectors ensure broad backplane compatibility across supported IBM and third-party platforms.

Questions about this item

When will the 128MB cache or mechanical parts need replacement?

The 128MB cache is solid-state and does not wear out; the 10000RPM mechanism is rated for continuous operation and typically lasts years before any service is required.

What limit appears first during sustained 12Gbps SAS writes?

The 10000RPM spindle and 128MB buffer set the sustained throughput ceiling; the 12Gbps SAS link is faster than the drive can feed continuously.

How much heat and noise does the 2.5" 10000RPM drive produce all day?

The 2.5" form factor and 10000RPM speed generate moderate heat and audible seek noise typical of enterprise SAS drives under constant load.
