BG4 系列

客戶級SSD


BG4 系列為體積輕巧的單一封裝 NVMe™ SSD,容量高達 1,024GB,並採用 PCIe® Gen3x4 通道介面,以及 KIOXIA 96 層 TLC BiCS FLASH™。BG4 SSD 具備更高的頻寬,以及更優異的快閃記憶體管理和主機記憶體緩衝 (HMB) 技術,提供單一封裝固態硬體中最佳的讀取效能 (高達 2,300MB/s 循序讀取和 390K IOPS 隨機讀取),以及高達 3.7W (標準值) 的有效耗電量。

 

BG4 系列推出 128GB、256GB、512GB 及 1,024GB 四種容量,外型規格選項包括表面黏著 M.2 1620 單一封裝或可拆式 M.2 2230 模組,因此適用於超薄型個人電腦、嵌入式裝置,以及資料中心的伺服器開機等輕薄型系統設計。

 

BG4 系列具有支援 TCG Opal 2.01 版的自我加密硬碟 (SED) 型號選項。

 

* 各地 SED 機型系列的供應情形並不相同。BG4 自我加密硬碟 (SED) 的規格將於 2019 年第三季發佈。

More features
  • Host Memory Buffer feature is supported.
  • SLC cache is supported.
  • Sanitize command is supported.
  • Product image may represent a design model.
  • Availability of the SED model line-up may vary by region.
  • Definition of capacity: KIOXIA Corporation defines a gigabyte (GB) as 1,000,000,000 bytes and a terabyte (TB) as 1,000,000,000,000 bytes.  A computer operating system, however, reports storage capacity using powers of 2 for the definition of 1GB = 230 = 1,073,741,824 bytes and therefore shows less storage capacity.  Available storage capacity (including examples of various media files) will vary based on file size, formatting, settings, software and operating system, such as Microsoft Operating System and/or pre-installed software applications, or media content.  Actual formatted capacity may vary.
  • 1 MB (megabyte) = 1,000,000 bytes.
  • IOPS: Input Output Per Second (or the number of I/O operations per second)
  • Read and write speed, tested on the state of "Host Memory Buffer (HMB) = On", may vary depending on the host device, read and write conditions, and file size.
  • MTTF (Mean Time to Failure) is not a guarantee or estimate of product life; it is a statistical value related to mean failure rates for a large number of products which may not accurately reflect actual operation.  Actual operating life of the product may be different from the MTTF.
