  • 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
500 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.

Write Endurance (TBW)

Shows the total amount of data (in TB) that the SSD can write over its lifetime, according to the manufacturer’s specifications. A higher value means greater theoretical endurance for frequent data writes.

The type of flash memory used by the SSD. It affects the drive's durability, performance, and cost.

Dimensions

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
680000 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.

    Stay away, guys, don't buy it, I've experienced it myself. It has a problem that doesn't occur for everyone, but you might be "lucky". Specifically, if I shut down the PC and then open it after a few hours, it doesn't detect the hard drive or the BIOS. I either have to reboot multiple times or cut off the power and turn it back on. You'll find more details in the following thread opened by WD themselves, who haven't provided any response.

    It entered the 11th generation NUC and works flawlessly. If it was going into my main system, I would either get the version with the cooler or install an aftermarket one, but for use in this specific system, it is not necessary.

    No complaints, it functions as it should.

    Flawless and fast, it does not come with a heat sink, so you have to buy it separately.
    I paired it with the be quiet cooling for the PS5. And in a test, I moved the 100GB game GTA from the storage space of the PS5 to the SSD in 1 to 1.5 minutes.
