Overview
The MZTL27T6HBLA-00A07 is the 7.68 TB E1.S 9.5 mm build of the Samsung PM9A3 Gen4 enterprise SSD. E1.S (EDSFF 1U Short) is the OCP-driven replacement for M.2 in server storage: it hot-swaps from the front, has proper signal integrity for Gen4 and Gen5, and packs far more drives per rack unit than 2.5-inch carriers.
At 7.68 TB with a 1 DWPD five-year rating and 14 PBW published endurance, this is a data-tier drive rather than a boot device - the E1.S slot count in a modern 1U chassis makes it practical to build a multi-hundred-terabyte all-flash tier inside a single rack unit.
The 9.5 mm thickness is the E1.S variant that fits standard front-loading EDSFF backplanes; the OCP 1.0 compliance marker indicates it meets the boot-drive specification used by hyperscale operators.
Key Benefits
E1.S 9.5 mm: front hot-swap EDSFF for high drives-per-RU density. 7.68 TB at 1 DWPD: data-tier endurance with 14 PBW. 1,000K IOPS read: Gen4 performance at full capacity. OCP 1.0 compliant: hyperscale EDSFF specification.
Applications
High-density all-flash tiers, OCP-specification storage nodes, AI data staging inside a single rack unit, CDN and media caches, and analytics tiers where drive count matters.
