日消息，苹果在即将推出的macOS 26 Tahoe 中首次引入了名为 ASIF 的磁盘映像格式，在虚拟存储技术领域取得重大进展。磁盘映像将得到大幅加速，几乎达到原生 SSD 的速度。ASIF 格式极大地提升了磁盘映像的处理能力，也包括虚拟机映像。磁盘映像长期以来一直是许多 Mac 用户日常使用的一部分 —— 无论是用于加密数据存储还是用于虚拟化。然而，之前的格式常常存在访问速度慢的问题，尤其是在启用加密时。即使在现代 Mac 的快速内部 SSD 上，传统映像的传输速率也常常低于 100 MB/s。ASIF 现在带来了巨大的飞跃：在 WWDC 2025 开发者大会上展示的新操作系统 Beta 版测试中，读写速度几乎达到了 SSD 的原生性能。在一台配备 M3 Pro 的 MacBook Pro 上，100 GB 的 ASIF 映像在读取时达到了 5.8 GB/s，写入时达到了 6.6 GB/s。即使启用加密，传输速度仍然很高，分别为 4.8 GB/s 和 4.6 GB/s。在一台配备 M4 Pro 的 Mac mini 上，甚至测量到了超过 8 GB/s 的写入速度。IT之家查询苹果开发者文档获悉，ASIF 全称为 Apple Sparse Image Format（苹果稀疏映像格式），该格式的文件在主机或磁盘之间传输更高效，因为它们的内在结构不依赖于主机文件系统的功能。ASIF 文件在文件系统中占用的空间与磁盘映像中实际存储的数据大小成正比。macOS 26 中，ASIF 映像只能通过硬盘程序或终端进行创建修改，因此门槛还是比较高的。此外，该格式目前只能用于 macOS 26，苹果尚未说明其他早期版本 macOS 是否以及何时可以读取 ASIF 映像。\n\n\n海量资讯、精准解读，尽在新浪财经APP","kind":"news","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0
