1. A capture system, comprising: a file system configured to organize data on a disk and to regulate read and write accesses; a plurality of queues associated with captured objects that are received through the capture system via network traffic, wherein the queues are associated with captured objects based on content of the captured objects, and wherein the disk is divided into a plurality of partitions for storing at least some of the captured objects, wherein the captured objects are indexed with a tag database comprising a data structure, in which each record of the data structure is configured to index a corresponding captured object according to information about the captured object, the information of each captured object including a content type associated with the captured object; a scheduler configured to select one of the plurality of queues for performing a particular write operation, wherein the scheduler implements a write policy that defines a threshold level of write performance to optimize the file system for write operations over read operations, and wherein the threshold level of write performance is adjustable up to a physical limit of the disk; and a block manager configured to select one of the partitions of the disk, wherein blocks of data are written from the selected queue to the selected partition.
