Abstract :
The NAND flash memory based SSDs are considered to replace the existing HDDs. But the disadvantage of SSD is degradation of write performance. Because a write in flash memory should be preceded by an erase operation, a write performance is reduced. To maximize the write performance, SSD is used with the TRIM command. NTFS and EXT4 are known to support TRIM. This paper is compared by a write performance for TRIM on each file system.
