WD SSC enabled

Hello sir I want to know about the enabled module of WD SSC so please provide me suitable information about the same.

WD SATA hard drives are factory set for workstation/desktop use. For enterprise storage requirements, the jumpers can be set to enable spread spectrum clocking or power-up in standby modes.

WD SSC

WD SATA drives are shipped from the factory either with or without a jumper shunt in the spread spectrum clocking (SSC) enable/disable position (on pins 1 and 2).

It is not necessary to add or remove the jumper shunt on the drive for workstation/desktop use. For enterprise storage environments, use the following advanced settings:

1. SSC Mode (Default 1):

Spread spectrum clocking feature enabled or disabled.

Default 1 setting is disabled or jumper shunt placed on pins 1–2. Removing the jumper enables the spread spectrum clocking feature.

SSC Mode (Default 2):

Spread spectrum clocking feature enabled or disabled.

Default 2 setting is disabled or no jumper shunt placed on pins 1–2.

Adding the jumper to pins 1–2 enables the spread spectrum clocking feature.

PM2 Enabled Mode:

To enable power-up in standby (power management 2 or PM2) mode, place a jumper on pins 3–4.

This mode enables controlled spinup by spinup command in accordance with ATA standard and is mainly for server/workstation environments operating in multiple-drive configurations.

Note:

The PM2 feature is not available on all WD SATA drives.

OPT1: 150 MB/s data transfer speed enabled or disabled.

Default setting is disabled. To enable 150 MB/s data transfer speed, place a jumper on pins 5–6.

OPT2: reserved for factory use (pins 7–8).
