Samsung always relies on multiple component vendors for its flagship smartphones. The Galaxy S8 and S8+ feature either the Snapdragon 835 processor or the Exynos 8895 chipset, depending on the market. The company also uses camera sensors from two vendors: Sony and System LSI. However, it appears that the company might also be using two types of storage solutions for its latest flagship smartphones.
Even though Samsung advertised that the Galaxy S8 and S8+ feature faster UFS 2.1 storage chips, the company is also using UFS 2.0 storage in some variants. According to a new report from XDA Developers, Samsung might be using Toshiba’s relatively slower UFS 2.0 storage chip in the Snapdragon variant of the Galaxy S8. Moreover, the company has quietly removed the mention of UFS 2.1 storage from its official specs list.
In day-to-day usage, you’re unlikely to notice the performance difference between UFS 2.1 and UFS 2.0 chips. However, if you still want to check the type of storage chip that is used in your Galaxy S8 or S8+, you can install a terminal emulator (like this one) and then enter the command: cat /proc/scsi/scsi and hit enter to see the specific model number. We’ve mentioned the chip model numbers in the list below.
- Samsung UFS 2.1 (KLUCG4J1ED-B0C1): Galaxy S8 and S8+ (Exynos variants)
- Toshiba UFS 2.1 (THGAF4G9N4LBAIRA or THGAF4G9N4LBAIRB): Galaxy S8+ (Snapdragon variant)
- Toshiba UFS 2.0 (THGBF7G9L4LBATRA or THGBF7G9L4LBATRC): Galaxy S8 (Snapdragon variant)
The sequential read speed of a UFS 2.1 chip could be somewhere around 800MB/s, while UFS 2.0 chips have read speeds of around 500MB/s. However, that may not be an accurate way to gauge real-life performance. Which storage chip does your Galaxy S8 or S8+ use?
