Technologies for establishing and managing a high-performance memory region of a solid state drive include reserving a region of a volatile memory of the solid state drive for storage of host data. Memory accesses received from a host may be directed toward the reserved region of the volatile memory or toward a non-volatile memory of the solid state drive. Due to the structure of the volatile memory, memory accesses to the reserved region may exhibit lower access timing relative to memory accesses to the non-volatile memory. As such, the reserved region may be utilized as storage space for journaling and logging of data and/or other applications. Upon shutdown or a power failure event, data stored in the reserved region of the volatile memory is copied to the non-volatile memory and subsequently reinstated to the volatile memory upon the next initialization event. 用于建立和管理固态驱动器的高性能存储器区域的技术包括保留固态驱动器的易失性存储器的区域以用于对主机数据的存储。从主机接收到的存储存取可以指向易失性存储器的保留的区域或者固态驱动器的非易失性存储器。由于易失性存储器的结构，对保留的区域的存储器存取相对于对非易失性存储器的存储器存取可以展现较低的存
