For example, a high-resolution JPEG image might range in size from megabytes. A 3-minute song saved in a compressed version may be roughly 3MB in size, and the uncompressed version may take up to 30 MB of disk space. Storage devices that hold 1, GB of data or more are measured in terabytes. Mostly the storage capacity of large storage devices is measured in TeraBytes.

Around , consumer hard drives reached a capacity of 1 TeraByte. Now, HDDs are measured in Terabytes e. Peta Byte One petabyte is equal to 1, TBs and precedes the exabyte unit of memory measurement. A petabyte is lesser in size than a pebibyte, which contains exactly 1, , , , , 2 50 bytes.

Most of the storage devices can hold a maximum of a few TBs, therefore, petabytes are rarely used to measure memory capacity of a single device. Instead, PetaBytes are used to measure the total data stored in large networks or server farms. Exa Byte One exabyte is equal to 1, PBs and precedes the zettabyte unit of memory measurement.

Exabytes are lesser than exbibytes, which contain exactly 1, , , , , , 2 60 bytes. The exabyte unit of memory measurement is so large, that it is not used to measure the capacity of storage devices. Even the data storage capacity of the biggest cloud storage centers is measured in PetaBytes, which is a fraction of 1 EB.

Instead, exabytes measure the amount of data over multiple data storage networks or the amount of data that is being transferred over the Internet for a certain amount of time.

Zetta Byte. One zettabyte is equal to 1, exabytes or 10 21 or 1, , , , , , , bytes. One zettabyte contains one billion TBs or one sextillion bytes which means it will take one billion one terabyte hard drives to store one zettabyte of data. Generally, Zettabyte is used to measure the large amounts of data and all the data in the world is just a few zettabytes. Yotta Byte One yottabyte is equal to 1, zettabytes.

It is the largest SI unit of memory measurement. It is a little bit smaller than yobibyte, which contains exactly 1, , , , , , , , bytes 2 80 bytes. It is a very large number that humans can evaluate. There is no practical use of such a large measurement unit because all the data in the world made of just a few zettabytes. The download speed Kbps is 1, Bits per second, not 1, Bits per second.
