  • 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.

Capacity
4000 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.
Communication Protocol
PCI Express 4.0

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.

NVMe
Yes

NVMe

Communication template that enhances the performance and speed of SSDs.

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

Form Factor
M.2 (Type 2280)

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.

M.2 (Type 2280)
The motherboard must support the form factor in order for the SSD to be installed on it. It is worth noting that M.2 drives are divided into those that use the SATA protocol and those that use PCI Express. Of the SSDs that use the PCI Express protocol, most also support NVMe technology, which allows them even faster speeds if supported by the motherboard.

Maximum 4KB Random Write
900000 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.

    This review is about the capacity: 2000 GB

    ​An absolute best in the PCIe 4.0 generation. It's fast, runs cool, and is highly reliable. Yes, it's DRAM-less, but that's exactly what makes it run much cooler. Highly recommend both the SSD itself and the seller!

    I have been using it for a few months as storage for large files and folders, so far it is flawless. I would recommend downloading the WD/SanDisk Dashboard for health monitoring and firmware updates.

    I use the drive for a second OS. Linux is indeed lighter and faster than Windows, but even with that in mind, the drive flies. It reaches almost 7 gbps in large file transfers, just as advertised

    Amazing drive, especially for laptops, because it heats up much less than its cousin, the SN850X (which is probably only for desktops), while maintaining comparable performance.

    Very good balance of cost, performance, temperature, and consumption.

    Ideal choice for a laptop where priority is increased autonomy and low temperature, with "quite good" performance.
