WD_Black SN770 review: A very good SSD for PC and PS5

So the M.2 band is presented in its dark attire and Without heatsink for 1TB model that we had. It is Gen4 SSD, which means it is compatible with Playstation 5. So we will have the opportunity to measure its performance under these circumstances.

The packaging is classic for the brand. Five years of warranty, performance information, desktop and laptop compatibility… It’s a pity that we didn’t take the opportunity to talk about PS5 compatibility, an uninformed user might miss out.

less energy

One of the first things that was highlighted for this new model is its energy efficiency. declared gain 20% Compared to the previous generation (750 SE). Consuming less for better performance also often means less heating.

When subjected to intense testing, when transferring several tens of gigabytes, its temperature is about 2 ° C lower than that of the Samsung 980 Pro. Both are equipped with the same general heatsink in order to prevent deterioration of their performance. So their energy efficiency appears to be real. The 770 was installed at a maximum of 38.8°C on the PS5.

On the other hand, Under pressure CrystalDisk, the latter is still installed at 67 ° C (with heatsink) on PC, which we strongly advise you to equip it with a heatsink if you activate Game Mode (maximum performance). In fact, from 60°C, the performance curve collapses in order to maintain the integrity of the SSD. This is not unacceptable, as it is a situation that does not exist in normal gameplay where temperatures reach PS5 temperatures.

If you compare it to its direct predecessor, the 750SE, it really needs to warm up seriously before it deteriorates enough to put itself in the best sequential reading.

Faster than his older brother

It must be said, the 750SE may seem disappointing in terms of performance gains, especially for the Gen4 bar. The 770 obviously performs better with read speeds of around 5100MB/s, versus the 3600 MB/s that the 750SE is offering. Obviously, this is felt in the game mode on the PC, but also on the console, because we did not fail to install it in the PS5. Remember while going through that Game Mode (which can be activated on PC) requires a device restart and keeps the power supply at full read load without trying to save power.

Equipped with a heat exchanger, Surprised by his speed. Transfer times were pretty good, even if you think first writes to an SSD are always faster. We note for example that it performs much better than the Samsung 980 Pro in this segment. Only the GT Sport makes it exceed the minute with a capacity of 115 GB.

However, it is the load times of the games that will be the rulers of peace and the results are also excellent in this sector. We find ourselves at similar times, at least very close to the Samsung 980 Pro and very tolerable compared to the console’s internal storage. Not content to be effective on PC, so the SN770 will be perfectly in place on the console.

Result with coolant on PS5: 38.3°C max

WD_Dashboard on PC to improve performance

Like many other brands, Western Digital introduces its own SSD management tool. The latter allows you to access SMART information about the health of your hardware (this is common to all SSDs), but also and Especially to activate the “Game” mode for the 770. An ability that it would be irrational not to activate on equipment of the black range and which, let’s remember, is intended for demanding use in games, both on a desktop and on a mobile device.

We also note with the various Workbench and especially the core CrystalDisk that the promotional mentions are not usurping. We often turn around 5187 MB/s, even when the disc has been severely damaged. Performance found in downloading and using games. Keep in mind that if it’s Gen 3 compatible, these numbers are obviously only valid if you have a PCI 4.0 port.

Performance is in accordance with the manufacturer’s data

The DW_Dashboard is perhaps less elegant than Samsung and its “Magician”, but it allows you to monitor what your SSD is doing in real time and take action if there should be an anomaly. In addition to the 800,000 IOPS advertised in the technical description, Western Digital reports an estimated uptime of 1,750,000 hours before any errors appear. Endurance ranges from 200 to 1200 TB depending on the capacity of the SSD considered. Life will be more than enough before you consider moving to the next evolution of a solid state drive (SSD) from Western Digital.

The 770 is a true evolution of the American group of memory media manufacturers. Much more than the 750SE over the 750SE, it improves performance enough to justify buying it. If it’s not the ultimate brand, it already offers pretty much enough offerings for fun use on a daily basis.
