Question 1

does this need a heatsink?

Accepted Answer

It purely depends on your use.  SSDs have a butter-zone of temperature for optimal usage.  This is roughly 35-50 degrees Celsius.  However, if you hit around 65-80 degree Celsius the cache, controller and eventually the internal pipeline on the NAND may overheat.  This will cause the SSD to thermal throttle to prevent issues.  Such throttling reduces performance.

Heavy random access loads, such as those created by some high resolution open world games with a lot of on-demand texture loading, particularly when the SSD has poor airflow or is in regions of the motherboard with high ambient temperature.

The label heat spreader is OK on these, but not as good as the heat sink on the heat sink version.  I would recommend the heat sink version over the other versions.

Most normal day to day computing and moderate gaming should not require a heat sink.  The same goes if you have a case with exceptional airflow.

Also, do note that the heat sink doesn't hurt, and it looks nice.

Question 2

Should I buy the WD_BLACK SN770 2TB or the WD_BLACK SN850X 2TB?

Accepted Answer

Choose the WD_BLACK SN770 2TB if you want a lower-cost PCIe 4.0 drive for gaming, everyday use, and general storage expansion. Choose the WD_BLACK SN850X 2TB if you want higher-end performance for heavier sustained writes, top-tier benchmark results, or a more premium desktop gaming build. Western Digital positions the SN850X above the SN770 in its lineup, and review data consistently shows the SN850X delivering materially higher peak throughput, while the SN770 remains a strong value-focused gaming SSD.

Question 3

Is the WD_BLACK SN770 2TB a good upgrade from the WD_BLACK SN750 SE?

Accepted Answer

Yes. The WD_BLACK SN770 2TB is the better choice if you are upgrading from an SN750 SE-class drive and want a newer PCIe 4.0 option with higher advertised throughput and better efficiency. Western Digital explicitly positions the SN770 as faster and more power efficient than the SN750 SE, and third-party reviews support that the SN770 is the more capable drive for modern gaming and mainstream performance use.

Question 4

Should I get the WD_BLACK SN770 2TB for a laptop, or choose a higher-end SSD for a desktop?

Accepted Answer

Choose the WD_BLACK SN770 2TB for a laptop or compact system if you want a fast PCIe 4.0 SSD with a strong reputation for efficiency and low-friction everyday responsiveness. Choose a higher-end model such as the SN850X if your desktop build is aimed at maximum benchmark performance or heavier sustained workloads. Reviews and community discussions often describe the SN770 as a practical fit for gaming laptops and mainstream systems, while flagship drives make more sense when peak speed matters more than efficiency or price.

Question 5

Is the WD_BLACK SN770 2TB worth it over the WD Blue SN580 2TB?

Accepted Answer

Buy the WD_BLACK SN770 2TB if the price gap is small and you want the faster option within Western Digital's DRAM-less TLC lineup. Buy the WD Blue SN580 2TB if your priority is keeping cost down for everyday gaming, school, or office use. Reviews commonly place the SN580 close to the SN770 for normal consumer workloads, but the SN770 is generally positioned and tested as the slightly faster step up.

Question 6

Who is the WD_BLACK SN770 2TB best for?

Accepted Answer

It is best for buyers who want a fast 2TB internal SSD for gaming, everyday productivity, and general PC upgrades without paying for a flagship model. It suits desktop builders and many laptop upgraders who want strong game load times and large storage capacity. It is less ideal for users who specifically want top-end sustained write performance, built-in heatsink convenience, or a PS5-focused drive.

Question 7

Should I buy the SN770 2TB or step up to a WD_BLACK SN850-class SSD?

Accepted Answer

Buy the SN770 if your priority is value, fast game loads, and a simple Gen4 upgrade for PC use. Step up to an SN850-class model if you want a more premium option for heavier workloads, stronger sustained performance, or clearer PS5-oriented positioning. In short: SN770 is the better value pick for many PC gamers, while SN850 is the better performance and console-focused pick.

Question 8

Is the WD_BLACK SN770 2TB a good SSD for a gaming PC or laptop?

Accepted Answer

Yes. The SN770 2TB is a good fit for mainstream to upper-midrange gaming PCs and many laptops that support an M.2 2280 PCIe NVMe drive. It offers fast Gen4 performance, 2TB of capacity, and good efficiency for everyday gaming, load-time reduction, and general use. The main trade-off is that it is a DRAM-less design, so buyers doing heavier sustained file transfers or workstation workloads may prefer a higher-tier model such as the WD_BLACK SN850 class.

Question 9

Is the WD_BLACK SN770 2TB a good choice for PS5 storage expansion?

Accepted Answer

Usually no, not as a first-choice PS5 upgrade. Retail Q&A repeatedly centers on PS5 compatibility and heatsinks, and the safer buying decision is to choose a PS5-targeted Gen4 drive with a heatsink, such as the SN850/SN850P class. The SN770 may physically fit with an added heatsink, but it is not the most straightforward option for buyers who want clear PS5-oriented compatibility and fewer installation questions.

Question 10

Does the WD_BLACK SN770 2TB need a heatsink?

Accepted Answer

For a typical desktop motherboard with an integrated M.2 shield or a laptop designed for NVMe upgrades, usually no separate heatsink is required. For PS5 use, buyers commonly ask about heatsinks, and adding one is generally expected. The practical decision point is not that the SN770 always requires a heatsink, but that console installs and some bare motherboard installs may need one depending on the host device.
