Description
NAND Flash Memory Type and Density
The Seagate XS3840SE70055 Nytro 3350 3.84TB SAS 12GB/s Scaled Endurance Internal Solid State Drive uses 3D TLC (Triple-Level Cell) NAND flash memory, which is a type of non-volatile memory that stores data in cells by varying the amount of electric charge held in each cell. 3D TLC NAND flash memory is known for its high density and cost-effectiveness, as it can store multiple bits of data per cell, allowing for higher storage capacity at a lower cost.
The XS3840SE70055 Nytro 3350 has a density of 3.84TB, which refers to the amount of data that can be stored on the drive. This capacity is achieved through the use of multiple NAND flash memory chips, which are arranged in a specific configuration on the drive’s printed circuit board (PCB).
The use of 3D TLC NAND flash memory allows the XS3840SE70055 Nytro 3350 to provide high capacity and reliable performance while remaining cost-effective, making it a suitable choice for enterprise applications that require large amounts of storage without sacrificing performance.
Interface and Speed
The Seagate XS3840SE70055 Nytro 3350 3.84TB SAS 12GB/s Scaled Endurance Internal Solid State Drive uses a SAS (Serial Attached SCSI) 12Gb/s interface, which is a high-speed, point-to-point interface that provides faster data transfer rates and greater reliability than traditional SATA (Serial ATA) interfaces.
In terms of speed, the XS3840SE70055 Nytro 3350 has sequential read and write speeds of up to 2100MB/s and 1700MB/s, respectively, and random read and write speeds of up to 240K and 40K IOPS (Input/Output Operations Per Second), respectively. These high-speed performance specifications make the drive suitable for demanding enterprise applications that require fast and reliable data access, such as data analytics, cloud computing, and virtualization.
Form Factor and Physical Dimensions
The Seagate XS3840SE70055 Nytro 3350 is a 2.5-inch internal solid-state drive (SSD) that follows the Small Form Factor (SFF) standard. It has a thickness of 15mm, making it thicker than standard 2.5-inch drives, which typically have a thickness of 7mm or 9.5mm. This allows the XS3840SE70055 to pack in more NAND flash memory chips and achieve a higher storage capacity of 3.84 terabytes.
The XS3840SE70055 uses a SAS (Serial Attached SCSI) interface with a speed of 12 gigabits per second (12Gbps), providing high data transfer rates and low latency for demanding enterprise applications. The drive also supports the SAS protocol’s full duplex capability, allowing data to be transmitted and received simultaneously, further improving performance.
The physical dimensions of the XS3840SE70055 are as follows:
- Form Factor: 2.5-inch
- Height: 15mm
- Width: 69.85mm
- Depth: 100.45mm
The drive’s SFF form factor and 2.5-inch size make it ideal for use in space-constrained server environments where larger drives may not fit.
