Systems and methods for automatic isolation of write data in non-volatile storage devices

A method comprising:

• receiving, from a host by a controller configured to control a non-volatile memory (NVM) comprising a plurality of blocks grouped into a plurality of superblocks, a first write command to write first write data and a second write command to write second write data;
• identifying one or more isolation regions comprising superblocks specified by the host, wherein the first superblock and the second superblock do not belong to the one or more isolation regions;
• determining, by the controller, a first lifetime of the first write data and a second lifetime of the second write data;
• determining, by the controller, that the first write data and the second write data are not to be mapped to the one or more isolation regions;
• determining, by the controller, that a difference between the first lifetime and the second lifetime is greater than a threshold;
• and
• in response to determining that the difference is greater than the threshold, and in response to determining that the first write data and the second data are not to be written to the one or more isolation regions, programming the first write data to a first superblock of the plurality of superblocks and the second write data to a second superblock of the plurality of superblocks that is different from the first superblock.
