Storage devices having minimum write sizes of data

A storage device, comprising:

• a non-volatile storage unit, wherein a capacity of the non-volatile storage unit is divided into a plurality of streams, and wherein the non-volatile storage unit comprises a plurality of dies, each of the plurality of dies comprising a plurality of planes, each of the planes comprising a plurality of erase blocks, and each of the erase blocks comprising a plurality of wordlines, wherein each stream comprises a plurality of user data dies of the plurality of dies, a first parity die, and a second parity die, wherein the plurality of user data dies are dedicated to storing user data;
• a volatile storage unit;
• and
• a controller coupled to the non-volatile storage unit and the volatile storage unit, wherein the controller is configured to:
• store p-parity data in the first parity die;
• store q-parity data in the second parity die, wherein q-parity data is a same size as p-parity data;
• calculate a minimum write size for commands to write data received from a host device, wherein the minimum write size is calculated to write a full wordline size of one erase block of each plane of each die dedicated to storing user data within a stream;
• restrict the host device through a verbal agreement or a handshake agreement to send the commands to write data in the minimum write size;
• receive one or more write commands from the host device in a size smaller than the minimum write size;
• hold the one or more write commands in the volatile storage unit until the one or more write commands aggregate to the minimum write size;
• and
• write the one or more write commands to the non-volatile storage unit once the one or more write commands are aggregated to the minimum write size, wherein the writing the one or more write commands to the non-volatile storage comprises programming the aggregated one or more write commands to a wordline of each erase block of the stream concurrently.

• a volatile storage unit;
• means for receiving commands to write data received from a host device in a minimum write size, wherein the minimum write size is set by multiplying a number of erase blocks in a stream dedicated to storing user data times a pages per cell of the wordlines times a wordline size, subtracting an amount of space dedicated to storing metadata of the storage device, store p-parity data in the first parity die, and store q-parity data in the second parity die, wherein q-parity data is a same size as p-parity data;
• means for aggregating one or more commands to write data received from the host device having a size smaller than the minimum write size, wherein the aggregating occurs within the volatile storage unit;
• and
• means for programming the write data in the minimum write size to the stream, wherein the means for programming occurs to a wordline of each erase block of the stream concurrently.
