First, a garbage collection process on a victim block of flash memory may be initiated. A garbage collection process may comprise a plurality of garbage collection operation. A program command and corresponding program data may be received. After a first garbage collection operation has finished and a portion of flash data from the victim block has been written to a free block, a portion of the program data may be written to that free block. If data remains in the victim block, a second garbage collection operation may be performed.

摘要： Disclosed herein is a mass prefetching method for disk arrays. In order to improve disk read performance for a non-sequential with having spatial locality as well as a sequential read, when a host requests a block to be read, all the blocks of the strip to which the block belongs are read. This is designated as strip prefetching (SP). Throttled Strip Prefetching (TSP), proposed in the present invention, investigates whether SP is beneficial by an online disk simulation, and does not perform SP if it is determined that SP is not beneficial. Since all prefetching operations of TSP are aligned in the strip of the disk array, the disk independence loss is resolved, and thus the performance of disk arrays is improved for concurrent sequential reads of multiple processes. TSP may however suffer from the loss of disk parallelism due to the disk independence of SP for a single sequential read. In order to solve this problem, this invention proposes Massive Stripe Prefetching (MSP). MSP includes an algorithm that detects a single sequential read at the block level. When a single sequential read is detected, prefetching is aligned in a stripe, and the prefetching size is set to a multiple of stripe size. Accordingly, the parallelism of disks is maximized.

摘要翻译： 这里公开了一种用于磁盘阵列的批量预取方法。 为了提高具有空间局部性和顺序读取的非顺序的磁盘读取性能，当主机请求读取块时，读取块所属的所有条带的所有块。 这被指定为条带预取（SP）。 在本发明中提出的节流带预取（TSP）是通过在线盘模拟来研究SP是否有益，如果确定SP不受益，则不执行SP。 由于TSP的所有预取操作都在磁盘阵列的条带中对齐，因此可以解决磁盘独立性损失，从而提高了多个进程的并行连续读取的磁盘阵列性能。 然而，TSP可能由于SP的单独顺序读取的磁盘独立性而受到磁盘并行性的损失。 为了解决这个问题，本发明提出了大规模条带预取（MSP）。 MSP包括在块级别检测单个顺序读取的算法。 当检测到单个顺序读取时，预取在条带中对齐，并且预取大小设置为条带大小的倍数。 因此，磁盘的并行性最大化。
