Dell T2TPF / F7M4M SanDisk Lightning Ultra Gen II Write Intensive SDLTMDKW-400G-5C20 / T2TPF  400GB SLC 12Gbps SFF Enterprise High-Endurance SAS SSD - Brand New OEM


Lightning® Write-Intensive 12Gb/s SAS Enterprise Solid State Drives

The new Lightning® Gen. II product family of 12Gb/s SAS SSDs doubles interface

speed providing the highest performance for mission-critical hyperscale, cloud and

virtualized data center application workloads. This next generation of Lightning SSDs

offer capacities ranging from 200GB – 1.6TB with random read/write performance

up to 190K/100K and sequential read/write speeds of up to 1000/600 MB/s. These

SSDs utilize the latest 19nm SLC and eMLC NAND flash technology combined with

an innovative parallel processing architecture to deliver industry-leading, predictable

performance, superior reliability (DWPD=25) and maximum value.

Lightning Ultra™ Gen. II SAS SSDs offer industry-leading predictable performance with

high availability for the analysis of large data sets. Available in 19nm SLC capacities from

200GB – 800GB2 and with random read/write performance of up to 190K/100K IOPS

and sequential read/write speed of up to 1000/600 MB/s1

. These SSDs are designed

for write-intensive applications such as High Performance Computing (HPC), Big Data

Analytics, Data Warehousing, Database Logging, Media Editing, and Indexing with a

heavy workload comprised of a 50/50 read/write mix. This SSD offers 25 full drive writes

per day (DWPD) .

SSD performance is dependent on the grade of NAND flash memory used, and sophistication of the controller and firmware. Lightning Write-Intensive SSDs are designed with an advanced innovative controller that uses a parallel processing architecture with single firmware binary to provide the industry’s leading sustained performance, low response times under peak conditions for predictable performance, and proven and tested endurance for superior reliability. Lightning SSDs have been designed to meet demanding, mission critical, 24/7 applications.


This drive is compatible with any server that accepts small form factor (SFF) SAS drives.
