PX05S 系列的第 4 代企業級 SAS 固態硬碟,延續了廣受市場肯定的 PX04S 系列產品優勢。PX05SH 系列,則針對寫入密集型虛擬資料中心、大數據分析以及高效能運算 (HPC) 等工作負載,進行最佳化。隨機寫入速度達 120k - 125k IOPS、隨機讀取速度達 270k IOPS 的 12.0 Gbit/s SAS 固態硬碟,提供獨特的客戶可調式電源與效能功能,確保了電源效率的最佳化或效能最大化。


其他功能還包括斷電保護及資料路徑保護等。每一機型皆可作為內建立即安全清除功能的自我加密磁碟 (SED),同時支援 pin-3 電源斷電機制,對於儲存媒體的機箱服務控制亦顯著改善。


全新的企業級寫入密集型固態硬碟,旨在因應最高等級的 eSSD 效能、可靠度和高品質的用途,可支援到傑出的 25 DWPD (每日磁碟寫入量)。PX05SH 系列提供了 200GB 到 1.6TB 的不同容量任君選擇。

  • Definition of capacity: KIOXIA Corporation defines a megabyte (MB) as 1,000,000 bytes, 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.
  • A kibibyte (KiB) means 210, or 1,024 bytes, a mebibyte (MiB) means 220, or 1,048,576 bytes, and a gibibyte (GiB) means 230, or 1,073,741,824 bytes.
  • 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.
  • DWPD: Drive Write Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day for five years, the stated product warranty period. Actual results may vary due to system configuration, usage and other factors.
  • Read and write speed may vary depending on the host device, read and write conditions, and file size.
  • IOPS: Input Output Per Second (or the number of I/O operations per second)
