  • 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

Description

The Western Digital Ultrastar DC SN655 ISE is an SSD with a capacity of 7.68TB. Its 2.5" form factor makes it ideal for replacing or upgrading a hard drive in a laptop, as well as an affordable choice for a desktop. It supports the PCI Express 4.0 interface and NVMe technology, delivering high speeds that can improve the experience of using demanding applications, provided the computer's motherboard supports them too.

Unlocking the full potential of SSDs for businesses

With dual-port redundancy and failover capability, end-to-end data protection, and additional business features, the SSD Ultrastar DC SN655 NVMe drives contribute to ensuring 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 datasets and reduce the time to retrieve information from big data, enabling efficient machine learning.

Benefits

The Ultrastar DC SN655 SSD drives 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 workloads of applications. Designed and built for the typical 2.5" SSD storage infrastructure, the SN655 includes support for U.2 and U.3 backplanes and features power loss protection and 2.5M (predicted) MTBF and 1.0 DW/D with a limited 5-year warranty.

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.
