我准备买一台有SSHD的新笔记本电脑.它代表固态混合驱动器,这意味着它有一个大型的常规硬盘驱动器,带有一个小的,通常是8GB的SSD,用于缓存经常访问的文件.

既然我是Linux用户而且我想要纯SSD速度,所以我认为如果我可以将SSD从HDD中分离并完全分开使用它会很棒.
我已经google了这个话题,但找不到任何有用的东西.根据*,有一个标准与驱动器分开通信,但我可能误解了.

有谁知道这个话题？

解决方法:

*的文章接着说,在某些情况下,可以从主机管理SSHD缓存：

SSHD products operate in two primary modes:

Self-optimized mode
In this mode of operation, the SSHD works independently from the host operating system or host device drives to make all decisions
related to identifying data that will be stored in NAND flash memory.
This mode results in a storage product that appears and operates to a
host system exactly as a traditional hard drive would.

Host-optimized mode (or host-pinning mode)
In this mode of operation, the SSHD enables an extended set of SATA commands defined in the Hybrid Information feature of the Serial
ATA International Organization standards for the SATA interface. Using
this feature, decisions about which data elements are placed in the
NAND flash memory come from the host operating system, device drivers,
host software or a combination of these host level components.

一点点谷歌搜索告诉我patches使用SerialATA Revision 3.2第13.20节中的混合信息功能已经提交审查,并且主机固定支持可能最早合并到3.19版本.
