Green Commitment

Enhancing energy efficiency with Promise Technology

As energy costs rise and businesses look to use power in more sustainable ways, Promise is making strides to offer technology solutions that better manage resources and waste. Since disk drives comprise 70% of the total power usage of the subsystem, Promise provides its customers with a tiered power management option that is user configurable and adaptable to application environments.



Green design

Using Promise's stepwise process, users can configure different levels of power stages. Each step in the management level is designed to save power. From the Active state to Level 1 when drive heads are unloaded, there is a 10 – 20% power savings. Level 2, with lower spindle speeds has a savings of 30 – 40%. Level 3, when drives are spinning down, promotes 70 – 80% in power savings. Additionally, when needed, the entire process can be skipped pending user discretion.

Promise mitigates environmental impact by developing green products that reduce power consumption. We have adopted a high-efficiency power supply with 80PLUS Bronze/Silver/Gold certification for the Vess and VTrak product lines with MAID 2.0 support and On/Off power scheduling.

Green production

All Promise products are RoHS, WEEE, ISO14001 and REACH compliant. Additionally, we are reducing the use of hazardous materials like Pb, Cd, Br and halogens in all our products.  Promise has also made a commitment to increase its usage of recycled materials whenever prudent.

Product recycling management

Our company hopes to bring all PROMISE products into compliance with the 3R Principles, Reduce, Recycle and Reuse. The goals we wish to achieve in this effort include:

  • Lowering Product Hazard
  • Extending Product Life
  • Energy Saving
  • Ease of Recycling

The details of efforts to achieve these goals are listed below according to location.

EU Zone:

Recycling plans follow the Waste Electrical and Electronic Equipment (WEEE) Directive from the EU and other regulatory requirements in various EU nations. Products sold in the EU zone will be recycled using the available local recycling systems. Products sold in the EU are required to be labeled for recycling into WEEE bins in compliance with WEEE Directive regulations.

We ask PROMISE customers in the European Union to please scrap PROMISE electronic and electrical products according to the WEEE Directive. Please send discarded products and materials to a qualified local recycling and disposal company for disposal.

Please DO NOT discard any WEEE labeled materials with general household waste.


The recycling process for waste IT products is primarily handled by the Environmental Protection Administration (EPA) in Taiwan. Companies are required to pay fees for the recycling process which are conducted according to regulations for imported products. These fees will be used for recycling, issuing subsidies, audit approval for quantities processed, management of recycling firms, and administration duties by the EPA.

For relevant recycling information in Taiwan, please refer to the website of the EPA’s Recycling Fund Management Board:
