With the Silicon Power 4TB UD90 NVMe M.2 SSD, you can expect great results in the aspect of storage capacity, and speeds. As aforementioned, game sizes especially with triple-A titles, are growing rapidly, with some above 100GB. With this in mind, a 4TB is certainly necessary and will keep you sustained for a very long time.

The read and write speeds on this occasion are also not features to scoff at. Data transfers that once took a while to complete, will now be over and done within seconds or minutes. This is dependent on how large these files are and the drive type the data is being transferred to.

This is thanks to the UD90’s NVMe M.2 nature, which is faster than SATA drives, and is leaps and bounds ahead of HDDs. Games and your chosen OS will load at a much faster rate, creating a near-seamless gaming and startup experience.

It’s important to keep in mind that those using handheld gaming devices like the Steam Deck, Lenovo Legion Go, or ROG Ally will need to rely on third-party adapters to use this SSD. This is due to the 2280 form factor size, which fits most PC or laptop motherboards.

Is now a good time to get your hands on this SSD?

While any time is a good time to get your hands on a 4TB SSD, pricing is always a huge aspect of this. Thanks to research on Camelcamelcamel, we can see that the Silicon Power UD90 is only just $34.01 above the lowest-ever price of $157.97.

With this in mind, you can confidently get your hands on this SSD without worrying about overspending. The price may fall in a future sale or perhaps Easter which is just days away, but most likely not too far below its lowest price. This is a steal for a 4TB SSD, likely ensuring you won’t need an upgrade any time soon.
