但是，虽然SSD的成本每个季度都在递减，但是SSD仍然比HDD昂贵。
But although SSD costs are declining every quarter, SSDs are still more expensive than HDDs.
与之前十年相比（1.3%），递减速度自2000年提高了一倍，达到每年2.7%。
The rate of decline has doubled to 2.7% per year since 2000, compared to the previous decade (1.3%).
固定百分比余额递减折旧：一种加速折旧的方法。在这一方法中，折旧率是直线法折旧率的一个倍数，每年用此折旧率乘以资产的未折旧成本。
An accelerated method of depreciation in which the rate is a multiple of the straight-line rate, which is applied each year to the undepreciated cost of the asset.
