Q0. What is the difference between NASPi & NASPi-Lite? [[File:NASPi-NASPi-Lite-Compare.jpg|900px|NASPi & NASPi-Lite Compare]] Q1. The SSD cannot start or is very slow
A： If you have a Raspberry Pi 4 and are getting bad speeds transferring data to/from USB3.0 SSDs, read this https://www.raspberrypi.org/forums/viewtopic.php?t=245931
A: As our test, 2.4G WIFI AP was usable. But different Raspberry Pi individuals have different degrees of WIFI interference. As well as aluminum alloy case will interfere with pi 4’s WIFI to a certain extent. So it is strongly recommend to use Ethernet or 5G AP. You can refer to video test of 5G WIFI AP: https://youtu.be/LKJVIBQFYXs
A: The thickness of 2.5" HDD/SSD on the market is generally 7mm, 9.5mm, 12.5 and 15mm，You only can choose <span style="color:red;">7mm or 9.5mm</span> thickness HDD/SSD, NASPi Lite is not compatible with 12.5mm and 15mm thickness 2.5" HDD/SSD.The thickness of 2.5" HDD/SSD should not exceed 9.8mm. In fact, most 2.5" HDD/SSD on the market are only 7mm thick.
A: Please refer to: [[Raspberry pi 4 can't find 5ghz wifi]]
A:The read and write performance is determined by the speed of the Raspberry Pi’s USB 3 bus and SSD. It should be noted that the Raspberry Pi’s USB3 bandwidth is only 3Gbps. Normally, the R/W speed is about 300MB/S.
A: According to the customer feedback(based on 2021-05-07-raspios-buster-arm64-lite), the NASPi is OK to use with PoE splitter, but make sure to use high quality PoE splitter, or the power maybe not enough to power the NASPi kit.
