  • Communication Protocol

    Most SSDs use SATA III or PCI Express.

    Almost all 2.5" SSDs connect via SATA III while most M.2 SSDs connect via PCI Express.


    PCI Express connection offers higher speeds, but this is mainly noticeable in demanding applications (high-resolution video processing, transferring large files, etc.) and is not necessary for everyday use.

  • Write Speed

    Indicative size for the maximum speed of the hard disk during data recording. The larger the size, the faster the data recording.

    For an SSD that uses the SATA III protocol, the average recording speed is 300MB/s, while for one with NVMe it is 1200MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

  • Read Speed

    Indicative size for the maximum speed of the hard disk during data reading. The larger the size, the faster the data reading speed.

    An average reading speed for an SSD using the SATA III protocol is 600MB/s, while for one with NVMe it is 2000MB/s.

    These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.

Description

The Ultrastar SN655 by Western Digital is an SSD drive with a capacity of 15.36TB. The 2.5" size makes it ideal for replacing and upgrading a hard drive in a laptop, as well as a cost-effective option for desktops.

It supports the PCI Express 4.0 communication protocol, offering high speeds that will enhance the user experience in demanding applications, provided that the computer's motherboard also supports it.

For installation in a desktop computer, you will need:

  • A SATA III data cable
  • An available SATA port on the motherboard
  • An available SATA power cable from the power supply

For installation in a laptop, no cables are needed, and the SSD simply plugs into the SATA slot.

Unlocking the Full Potential of SSDs for Businesses

With dual-port redundancy and failover capability, end-to-end data protection, and additional enterprise features, the Ultrastar DC SN655 NVMe SSDs help ensure the security and availability of your data when needed. With high-capacity and low-latency performance reaching up to 1.1 million IOPs, storage providers are able to effectively increase capacity for modern applications that process large unstructured data sets, reduce time to insight from big data, and enable efficient machine learning.

Features

The Ultrastar DC SN655 NVMe SSDs include the next-generation Western Digital NVMe 1.4b controller with PCIe Generation 4.0 interface and Western Digital BiCS5 TLC 3D NAND to enable higher capacities and performance at scale for increasingly larger application workloads. Designed and built for the standard 2.5" SSD storage infrastructure, the SN655 includes support for U.2 and U.3 backplanes and features power loss protection and MTBF 2.5M (predicted) and 1.0 DW/D with a limited 5-year warranty.

Capacity
15360 GB

Capacity

The golden ratio of cost and capacity for now is 500GB and 1TB.

For gaming or professional programs that require a lot of space for their installation, a capacity of at least 500GB is recommended. 

As an indication, a 1TB hard drive can hold about 250 thousand photos taken with a 12MP camera or 250 movies.

Dimensions

Form Factor
2.5''

Form Factor

The term form factor refers to the physical size of SSDs. The motherboard must support the form factor of the SSD in order for it to be installed.


The higher speeds offered by an NVMe drive are mainly applicable to demanding applications (such as high-definition video processing, transferring large files, etc.) and are not necessary for everyday use.

2.5''
The most classic size of SATA SSD hard drive.

HDD hard drives in laptops are of this size, so upgrading with an SSD is the right choice.

Performance

Read Speed
6800 MB/s

Read Speed

Indicative size for the maximum speed of the hard disk during data reading. The larger the size, the faster the data reading speed.

An average reading speed for an SSD using the SATA III protocol is 600MB/s, while for one with NVMe it is 2000MB/s.

These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable. 
Write Speed
3700 MB/s

Write Speed

Indicative size for the maximum speed of the hard disk during data recording. The larger the size, the faster the data recording.

For an SSD that uses the SATA III protocol, the average recording speed is 300MB/s, while for one with NVMe it is 1200MB/s.

These differences make sense in particularly demanding use cases (e.g. high-resolution video editing). For most users, the differences will not be noticeable.
Maximum 4KB Random Write
1100000 IOPS

Maximum 4KB Random Write

Indicative size for the maximum speed of the hard disk in data recording during general use, for example (opening the computer/using applications). The larger the size, the faster it is in these functions.

Average read speed for an SSD using the SATA III protocol is 80,000 IOPS, while for one with NVMe it is 380,000 IOPS.

These differences make sense in particularly demanding use (e.g. high-resolution video editing). For most users, the differences will not be noticeable.
