A stack of ten silver 2.5 inch SAS hard drives with black caddy trays

DELL

DELL X162K ST9146852SS 146GB 15000RPM SAS 2.5in internal hard drive

SKU CH-XXJ4-1386G

A 146 GB, 15000 RPM SAS drive with 16 MB cache, hot-swappable 2.5-inch form factor and included caddy tray

  • 146 GB capacity for dense storage in a 2.5 inch form factor
  • 15000 RPM spindle speed delivers fast data access for demanding workloads
  • SAS 6 Gb/s interface supports high-throughput server and storage array connections
  • 16 MB cache buffers bursts to sustain performance during heavy I/O
  • Hot-swappable design with included R Series caddy enables drive replacement without system downtime

146 GB 15 000 RPM SAS drive

This 146 GB Dell X162K spins at 15 000 RPM and connects through a SAS 2.0 interface running at 6 Gbps. It uses a 2.5 inch form factor and ships with an R-series caddy for hot-swap bays. The drive is new and intended for Dell PowerEdge servers and storage arrays. A 16 MB buffer handles burst traffic.

Suited for high-IO server workloads

The combination of 15 000 RPM spindle speed and 6 Gbps SAS suits transaction-heavy databases, mail stores and tier-one storage pools that demand low latency. Systems limited to slower interfaces or lacking hot-swap backplanes cannot use the drive as designed. Buyers needing more capacity per spindle or solid-state latency should consider other options.

SAS 2.0 6 Gbps interface decides fit

The single specification that determines compatibility is the SAS 2.0 interface operating at 6 Gbps. Your controller or backplane must support this exact protocol and speed; otherwise the drive will not negotiate a link. Verify the host adapter and cabling before purchase.

Questions sur cet article

Which lot size should I choose for my storage array?

The listing is a single lot of 10 drives, each 146 GB, so you receive ten 2.5-inch SAS units with trays in one purchase.

What does the 15000 RPM rating deliver in a server?

The 15000 RPM spindle gives very low latency and high IOPS for random workloads such as databases or virtualisation on Dell PowerEdge systems.

What does the SAS 2.0 6 Gb/s interface cap in practice?

The SAS 2.0 link tops out at 6 Gb/s, so sustained throughput cannot exceed that ceiling even on faster backplanes.
