Things to Consider
This drive is not suitable for OS boot drives or application installations due to the relatively slow random access of HDDs compared to SSDs. The price tag of around ¥240,000 is significant, so budget-conscious users may want to compare with other 16TB external HDDs from Seagate or Western Digital. The cooling fan produces some noise, which may be noticeable in quiet rooms. Additionally, USB 5Gbps is not the fastest interface; if you need higher speeds, consider Thunderbolt or USB4 alternatives, though they may be more expensive.
