Ultrastar SSD1600MM SAS SSD

1600GB, 800GB, 400GB & 200GB
Enterprise MLC 12Gb/s SAS
Solid-State Drives

  • Outstanding Performance – Speeds up to 100 times faster than HDDs
  • Mainstream Endurance – 10 drive writes per day (DW/D) for five years
  • High Reliability – 2.5M hours mean time between failure (MTBF)
  • Encryption Options – TCG compliance, secure erase, instant secure

With the highest reliability rating in the industry for MTBF, it’s no wonder why year over year HGST is the #1 market share leader in SAS SSDs. To meet today’s ever increasing needs around reliability, endurance and performance in demanding enterprise environments, the second generation Ultrastar 12Gb/s SAS SSD family of products (SSD800MH.B, SSD1600MM and SSD1600MR) is a solid choice, resulting from decades of proven enterprise storage expertise in SAS design, reliability, firmware, customer qualification and system integration. The mainstream endurance Ultrastar SSD1600MM SSD delivers 10 drive writes per day for five years, and also offers a broad range of encryption options including secure erase, instant secure and TCG compliance.
