三星 T5 的规格与设计
三星在 2017 年发布 T5 时列出的容量为 250GB、500GB、1TB 和 2TB。不同容量与版本的配色不完全相同，后续资料还列出玫瑰金和金属红。机身重 51 克，尺寸为 74 × 57.3 × 10.5 mm，体积小，适合随身携带。

以上是三星发布资料中的规格，不等于每台电脑上的实测结果。三星在发布新闻稿中由 Memory Business 品牌产品营销高级副总裁 Un-Soo Kim 表示，T5 延续了三星在便携存储领域的领先与创新；这是厂商宣传性表述，不是独立性能测试结论。三星 T5 发布资料
实际速度：540 MB/s 是标称上限，不是保证
三星公布的最高传输速度为 540 MB/s。能否接近这个数字，取决于电脑端口、线缆、系统、文件类型和传输条件；接口标为 USB 3.1 Gen 2，也不代表所有连接组合都能达到标称速度。

El País 在 2019 年对其测试的 250GB T5 进行文件夹复制，40GB 文件夹的一次记录用时 2 分 44 秒。不过，该文报告重复传输结果波动明显，约从 2 分 30 秒到 7 分钟。这个单一媒体测试及其波动只能说明特定测试环境中的表现，不能用来预测你的拷贝时间。El País 的 T5 测试
连接电脑或其他设备前要检查什么
三星发布资料称包装内附两条线：USB-C 转 USB-C，以及 USB-C 转 USB-A。连接前应确认设备端口、所用线缆和操作系统支持相应连接；仅凭随附线缆不能保证每种电脑、手机或其他设备都兼容。三星公布的包装线材信息

密码保护与 AES 加密如何理解
T5 的密码保护是可选功能，三星称其使用 AES 256-bit 硬件加密。不能把这项能力理解为硬盘出厂时已经自动启用保护：需按设备提供的设置流程启用密码功能。三星资料还说明了安全功能，但这里没有足够依据承诺忘记密码后能够恢复盘内数据或绕过保护。三星 T5 产品信息

T5 仍可作为基础便携 SSD 考虑，但它是较早发布的型号，购买判断应以目标市场实际商品为准。三星英国官网的 1TB 产品页标注“不再销售”（No longer available）；这只说明该地区、该容量的官方页面状态，不能据此断定全球所有容量都已停产或无货。三星英国 1TB T5 产品页

- Superfast read write speeds: SSD with V-NAND offers ultra-fast data transfer speeds of up to 540MB s (up to 4.9x faster than external HDDs); Ideal for transferring large-sized data including 4K videos, high-resolution photos, games and more

- 购买前核对容量、卖家、商品状态、保修条件及所在地的实际价格。
- 如果是二手或较旧库存，确认商品来源与状态，避免只依据产品名称判断版本或真伪。
- 若速度优先，可把三星 T7 纳入比较。TechRadar 2026 年选购文章列出的 T7 标称最高读取速度为 1,050 MB/s、写入速度为 1,000 MB/s；这不是与 T5 在同一条件下进行的对照测试。购买前仍应核对 T7 的本地价格、容量、接口与现货情况。TechRadar 2026 年便携 SSD 选购文章
因此，T5 是否划算取决于你能否以合适价格买到状态可靠、容量合适的产品。若没有明显价格优势，比较更新型号的规格与当地商品条件更稳妥；不要把 T7 的速度数字当作两款硬盘同场测试的结论。
