Abstract: Systems and methods are disclosed herein for multithreaded access to cloud storage. An exemplary method comprises creating a plurality of mount points by mounting, by a hardware processor, a plurality of file systems on a computer system, creating an image file on each of the plurality of mount points, instantiating, for each of the plurality of mount points, a block device on the image file, creating a union virtual block device that creates one or more stripes from each block device, delegating a request for accessing the union virtual block device, received from a client, to one or more block devices and merging a result of the request from each of the one or more block devices and providing the result to the client.
