DDrdrive固态硬盘上市价格昂贵性能超强

虽然性能无法超越ioDrive，但是DDrdrive发布的PCIe接口固态硬盘X1仍然在价格和速度上占有优势。

与普通SSD固态硬盘驱动器不同，DDrdrive X1使用了两种不同的存储单元，分别是4GB DRAM内存和4GB NAND闪存。通过PCIe接口卡，DDrdrive X1把两种单元混合在一起，依靠DRAM内存发挥性能，用NAND来存储数据。

据PC Perspective的评测显示，该驱动器的“独立单元IOPS（每秒输入/输出操作）性能无人能及”，如果与Fusion-io的ioDrive相比，实现同样IOPS性能的成本仅是ioDrive的五分之一。虽然与ioDrive相比要相对便宜，不过DDrdrive X1 4GB版本的价格仍然卖到了1495美元的天价。
