Lenovo has again showcased the capabilities of their upcoming gaming smartphone, the Legion Y90. This time they showed off their storage chip capabilities.
First, the storage in the Legion Y90 does not only use a UFS 3.1 chip, but also an SSD. This is not the first time that a cellphone has used an SSD chip as storage, because Apple has been doing it since the iPhone X.
However, the Legion Y90 does not only use an SSD, but also a UFS 3.1 chip configured with RAID 0 to produce higher speeds, as quoted by GSM Arena, Monday (21/2/2022).
For information, RAID is a data storage virtualization technology that combines multiple physical drives into one. There are several configuration options with different purposes, such as RAID 1 for data security (1 storage will be used as a backup), or RAID 0, as used in the Legion Y90.
In a RAID 0 configuration, the stored data will be 'split' into two or more storages. As a result, the speed (in theory) will be equivalent to the sum of the speeds of each storage.
However, there is a downside to RAID 0, which is that there is no redundancy or data stacking. So if one storage chip is damaged, then all the data including the other chips will also be damaged.
RAID 0 is commonly used in high-end PCs or laptops, but this may be the first time it has been used in commercially available mobile phones. Lenovo claims read and write speeds in the Legion Y90 storage will increase by 50%.
This gaming phone is scheduled to launch on February 28, and is the successor to the Legion 2 Pro. The screen is 6.92 inch AMOLED, with Snapdragon 8 Gen 1 SoC.
5,600 mAh battery with 68W fast charging, which promises to fully charge the dual cell battery used in 36 minutes.
