前两天在用macbook时,把u盘和移动硬盘连接在mac上存储文件时,发现只能读取不能存储文件。当时比较懵。
难道macbook不能兼容移动硬盘和u盘。 后来查阅了一下才清楚,原来我的移动硬盘和u盘是ntfs格式的,macbook是不能存储ntfs格式的。mac能正常读取和存储的格式是 fat32和exFAT这两种格式。
具体说一下 fat32 exFAT 和 ntfs 这几种格式的区别吧。
首先先给大家介绍下这三种格式的特点。
FAT32
FAT32文件系统用4个字节(32位)空间来表示每个扇区配置文件的情形,所以叫FAT32。分区容量最低是512M,而上限的话不同的操作系统都不一样,WinXP系统最大可以做到2TB的FAT32分区。存储单个文件不能大于4GB, 可以在 windows 和 mac 下正常使用。
NTFS
NTFS文件系统是windows NT核心和高级服务器网络操作系统环境的文件系统。NTFS系统比FAT32的可靠性更高,可以支持更大的分区和更大的文件,此外还有不少FAT32没有的功能,比如压缩分区、文件索引、数据保护和恢复、加密访问等。可以操作大于4GB的单个文件, 不能在 mac 系统下存储文件。
exFAT
exFAT文件系统是微软在windows embeded5.0以上引入的一种适合于闪存的文件系统,主要是为了解决FAT32不支持4G或更大文件的问题而推出的。
FAT32与exFAT可用4GB文件的区别:
大多数优盘在格式化时默认FAT32,最大优点就是在一个不超过8GB的分区中,FAT32的每个簇容量都固定为4KB,与前代相比可以大大地减少磁盘的浪费,提高磁盘利用率。
虽然对于最大分区容量的支持上面,FAT32的2TB最大分区容量至今仍不过时,但FAT32无法传输并存放超过4GB容量的光盘ISO镜像、高清视频、各种图形作品文件等等,这是最致命的弊端。而exFAT格式在苹果本或者是Windows电脑上都可以格式化,并且在两个系统之间可以互相无障碍使用。相比之下,exFAT格式就没有4GB文件传输限制了。
其实FAT32与exFAT存在着一个升级关系,这两种文件系统都支持OS X系统与Windows系统,如果你将U盘格式化成这两种文件系统,在不同操作系统电脑上可以畅通无阻地使用。
NTFS相比FAT会让闪存性能降低
NTFS是相当流行的,但多见于硬盘。XP、Vista、Win7默认都会将分区格式化为NTFS系统,可以说NTFS是目前最好的磁盘文件系统。
优盘在格式化为NTFS时,实际可用容量与其他文件系统形式也有所差别,虽然使用中感受并不是很大。另外,在格式化U盘时,容量在64G甚至更大规格时,系统识别自动格式化为exFAT与NTFS格式,会便于优盘在不同操作系统电脑上无障碍使用。
但是,NTFS也有他的缺点,NTFS分区采用“日志式”,因为要记录磁盘的详细读写操作,对U盘这种快闪存储介质会造成较大的负担,比如同样存取一个文件或目录,在NTFS上的读写次数就会比FAT32更多,理论上NTFS格式的U盘比较容易损坏。并且由于U盘带宽有限,NTFS频繁读写占据通道会让磁盘性能降低。
以上便是关于U盘文件系统FAT32、exFAT、NTFS之间的区别和特点介绍,FAT32与exFAT之间最大的差别在于能否支持4GB及以上容量单个文件的传输、查看与编辑;而FAT系列文件系统与NTFS之间最大的区分在于文件存取的方式,后者长期使用可能会让闪存类存储产品性能降低.
综上所述 ,结论就是: 在windows台式机中系统盘和硬盘基本 格式化为NTFS 就好了。 移动存储(移动硬盘和U盘)就格式化为 fat32和exFAT 这两种格式就行了。 也可以分成2个分区 ,一个分区格式化为fat32 用于小文件的存储 ,一个分区格式化为 exFAT 格式, 用于存储大于4GB的文件。 fat32和exFAT 两种格式都能被 windous 和 mac 正确识别。
