美光 Micron 3400 SSD 评测:规格、实测表现与购买前须知

Micron 3400 是面向 OEM 整机的 PCIe Gen4 SSD。本文整理其不同容量规格、1TB 独立测试结果,以及购买或替换时的兼容性与保修检查要点。

Micron 3400 是一款面向 OEM 整机厂商的 M.2 2280 PCIe Gen4 NVMe SSD,并非以零售升级盘为主要定位。它的官方顺序读取标称值为 6,600 MB/s,但 StorageReview 对 1TB 样品的测试中,顺序读写峰值约为 3.4GB/s 和 1.25GB/s;评测认为它在合成负载下落后于多款主流 Gen4 SSD。若你在预装电脑里遇到这块盘,或考虑购买 OEM 拆机盘,关键是同时核对容量、主机兼容性、整机保修和实际售价,而不能只看规格表上的读取速度。

Micron 3400 是什么类型的 SSD?

Micron 3400 是 Micron 面向客户端 OEM 市场的固态硬盘,采用 M.2 2280 尺寸、PCIe Gen4 接口和 NVMe 1.4。Micron 将该系列定位用于工作站、游戏电脑和企业 PC;StorageReview 在 HP Z2 Mini G9 中取得了评测样品。它因此常见于预装整机,具体零售或拆机产品的来源、配件和售后则要看卖家说明。

Micron 官方产品页将 3400 列在客户端 SSD 产品中;其产品简报列出 512GB、1TB 和 2TB 三种容量。Micron 3400 官方产品页 · Micron 3400 产品简报

官方规格:容量不同,标称写入速度也不同

下表的顺序速度、随机读取和耐久度来自 Micron 2021 年产品简报,属于厂商规格值,并非任意电脑或负载下都能达到的实测保证。简报注明规格可能变更。

#1 Best Overall
Micron 3400 512 GB Solid State Drive - M.2 2280 Internal - PCI Express NVMe (PCI Express NVMe 4.0), 0.9"x3.1"
  • With a capacity of 512 GB, you have large storage space for all your documents and data
  • 256-bit encryption protects your PC from hackers and thieves by encoding all your data
  • With the stunning reading speed of 6600 MB/s, get faster boot times and improved overall computing performance
  • Write speed of 3600 MB/s enables you to perform write-related tasks in seconds rather than minutes
  • PCI Express NVMe 4.0 interface provides quick data transfer and greater throughput
容量 标称顺序读取 标称顺序写入 标称随机读取 标称耐久度
512GB 6,600 MB/s 3,600 MB/s 360K IOPS 300 TBW
1TB 6,600 MB/s 5,000 MB/s 630K IOPS 600 TBW
2TB 6,600 MB/s 5,000 MB/s 720K IOPS 1,200 TBW

Micron 简报还列出该系列随机写入标称值为 700K IOPS、典型读取延迟 55µs、典型写入延迟 14µs。厂商规格有助于确认产品档次,但不同测试的队列深度、数据类型、盘体状态和主机平台并不相同,不能据此直接推断实际应用速度。

StorageReview 实测表现如何?

StorageReview 于 2022 年 4 月 12 日发布的评测针对 1TB 样品。其合成测试报告 4K 随机读取峰值 396K IOPS、随机写入 206K IOPS、64K 顺序读取 3,400 MB/s、顺序写入 1.25 GB/s。测试结果低于该评测中多款主流 Gen4 SSD;这些测试的负载、队列和预处理设置各异,不能与 Micron 产品简报的标称值当作同条件的一对一对照。

在该评测的 SQL Server 测试中,使用 Windows Server 2012 R2 客户机、SQL Server 2014 和 15,000 个虚拟用户,1TB 样品平均延迟为 5ms,在参测产品中居中。这是特定服务器负载与测试平台的结果,不代表日常桌面任务的延迟表现。

StorageReview 的总结认为,3400 相较其定位而言,表现不及主流 Gen4 消费级 SSD。评测当时的对比组包括 Corsair MP600 Pro XT、Kingston KC3000、Sabrent Rocket 4 Plus、Samsung 980 Pro、Seagate Firecuda 530 和 WD SN850;这组旧评测不能说明这些型号今天的价格或市场排名。StorageReview:Micron 3400 SSD Review(2022 年 4 月 12 日)

Micron 3400 值得买吗?

如果你的电脑原本就配有 Micron 3400,或厂商指定了这一型号,规格和 OEM 来源本身并不构成升级或更换的理由。若你在选购一块通用零售 Gen4 SSD,现有独立测试没有显示 3400 在合成性能上胜过主流同代产品,因此不宜单凭 6,600 MB/s 的标称读取速度下单。只有在具体容量、价格、兼容性和售后条件都合适时,才有必要把它纳入候选。

StorageReview 当时记录该盘没有独立公开保修、保修随整机销售。购买 OEM 拆机盘或单独销售的产品时,不能据此假定自己享有 Micron 独立保修;应以卖家书面退换条款及原整机厂商对该序列号的保修政策为准。

购买或替换前,逐项核对这三件事

  1. 确认接口和尺寸:检查电脑说明书或厂商支持页面,确认有 M.2 2280 插槽,并支持 NVMe/PCIe SSD。M.2 只是外形规格,不能据此认定 SATA 与 NVMe 盘可以互换;还需核对主板支持的 PCIe 代际及整机限制。
  2. 核对容量与实际产品:确认商品是 512GB、1TB 还是 2TB,并核对标签和型号。不同容量的标称顺序写入速度不同,拆机盘还应确认是否为所述型号、是否附带原机配件或散热片。
  3. 落实保修和总成本:询问卖家保修由谁承担、期限多长、是否支持退货,以及 OEM 盘能否凭序列号获得厂商服务。当前价格、库存和商品页因销售渠道而异,应以购买当时的实际报价及书面售后承诺判断是否划算。

拆下来的 3400 能否做外置盘?

若换下的 SSD 状态正常,可以考虑配合支持 NVMe/PCIe 的 M.2 2280 外置盒使用。下单时要确认外置盒明确支持 NVMe/PCIe,而不是只支持 M.2 SATA;两者外形可能相似,但协议不同。实际传输速度还会受外置盒控制器、USB 或其他连接接口、线材和主机端口影响。
