A computer-implemented method, according to one embodiment, includes: receiving an access request for data in a first block of storage space in memory, and returning the data in the first block of storage space in response to the access request. An identifier at an end of the data in the first block of storage space is also located, and pointers included in a trailer appended to the identifier are used to identify additional blocks of storage space which include data having temporal locality with the data in the first block of storage space. The data in each of the identified additional blocks of storage space is further prepared for use.
