*Green purchasing is the practice of considering carefully whether you really need the product or service you are purchasing, and considering its environmental impact along with the usual criteria of price, quality, convenience and design. Purchasers are encouraged to seek out products with the least environmental impact (such as Eco Mark products).
I-O DATA product categories that conform to the criteria of the Law on Promoting Green Purchasing are as follows.
The energy consumption efficiency shall not exceed the Standard Energy Consumption ate obtained by the formula of applicable category in Table
1.Magnetic disc drive units that meet any of the following criteria will not be regarded as a magnetic disc drive unit under consideration in the evaluation criteria in this section.
Category | Formula for calculating standard energy consumption efficiency | |
---|---|---|
Type of magnetic disk unit | Shape and performance of magnetic disk unit | |
Single Unit disk | Disk size exceeding 75mm; 1disk | E = exp(2.98 x ln(N) – 28.6) |
Disk size exceeding 75mm; 2 or 3 disks | E = exp(2.98 x ln(N) – 29.3) | |
Disk size exceeding 75mm; 4 or more disks | E = exp(2.98 x ln(N) – 29.5) | |
Disk size exceeding 50mm, and no more than 75mm; 1 disk | E = exp(2.98 x ln(N) – 28.6) | |
Disk size exceeding 50mm, and no more than 75mm; 2 or 3 disks | E = exp(2.98 x ln(N) – 29.4) | |
Disk size exceeding 50mm, and no more than 75 mm: 4 or more disks | E = exp(2.98 x ln(N) – 29.8) | |
Disk size exceeding 40mm, and no more than 50mm; 1 disk | E = exp(2.98 x ln(N) – 27.2) | |
Disk size exceeding 40mm, and no more than 50mm; 2 or more disks | E = exp(2.98 x ln(N) – 28.8) | |
Sub-system | E = exp(2.00 x ln(N) – 19.7) |
