Performance analysis of SSD write using TRIM in NTFS and EXT4

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.
