Scratch space is space on the hard disk drive that is dedicated for storage of temporary user data. It is unreliable by intention and has no back up. Scratch disks may occasionally be set to erase all data at regular intervals so that the disk space is left free for future use. The management of scratch disk space is typically dynamic, occurring when needed. Its advantage is that it is faster than e.g. network filesystems.

| - Der Scratch-Speicher (häufig Scratch-Disk, von engl. scratch, kratzen) ist ein nichtflüchtiger separater Speicherbereich, der einzig für temporäre Dateien verwendet wird. Während Computer früher regelmäßig über separate Hardware für Scratch-Speicher verfügten, ist der Begriff heutzutage nur noch in Nischenbereichen des Big Datas verbreitet, etwa High Performance Computing, Videobearbeitung oder Bildbearbeitung.

- 塗銷空間（英語：Scratch space），在硬碟上的一塊記憶空間，只提供暫時的資料儲存，不能被用來儲存可以被永久備份的檔案。系統可以設定周期性的清空這個區域的所有資料，讓這塊磁碟空間在將來可以繼續使用。這個區域的管理，通常是動態式的，只有在需要使時用時才進行。 塗銷空間通常使用於圖形設計程式，像是Adobe Photoshop。當程式需要更多記憶體空間，而系統的RAM提供的數量不足時，也可以使用這塊空間來暫時儲存資料。 (zh)

- Scratch space is space on the hard disk drive that is dedicated for storage of temporary user data. It is unreliable by intention and has no back up. Scratch disks may occasionally be set to erase all data at regular intervals so that the disk space is left free for future use. The management of scratch disk space is typically dynamic, occurring when needed. Its advantage is that it is faster than e.g. network filesystems. Scratch space is commonly used in scientific computing workstations, and in graphic design programs such as Adobe Photoshop. It is used when programs need to use more data than can be stored in system RAM. A common error in that program is "scratch disks full", which occurs when one has the scratch disks configured to be on the boot drive. Many computer users gradually fill up their primary hard drive with permanent data, slowly reducing the amount of space the scratch disk may take up. Partitioning off a significant fraction of the boot hard drive and leaving that space empty will ensure a reliable scratch disk. Hard drive space, on a per-gigabyte basis, is far cheaper than RAM, though performs far slower. Though dedicating a separate physical drive from the main operating system and software can improve performance, a scratch disk will not match RAM for speed. (en)
