Waarschuwing: Laptops with Solid State Drive (SSD) cannot be turned off

From Dafna Tachover, We are the Evidence
Our investigation reveals that wireless / radiation in its laptops with Solid State Drive (SSD) cannot be turned off. HP admitted.
Apparently the SSD in HP laptops uses wireless to communicate rather than a wired circuit as with regular hard drives. So even when you disable all wireless antennas and drivers, the computer continues to emit radiation and the levels are not insignificant. We measured about 0.5 Milliwatt/m2.
How did we discover it? A friend bought a new laptop and although I disabled all relevant drivers, it continued to emit RF. I identify the area from which the transmission was coming - it was on the right side, near the edge in the middle. I contacted HP tech department and after an hour on the phone they confirmed that the reason for the RF is that while the SATA drive connects internally with a wired circuit, the SSD connects wirelessly.
What is SSD ? The difference between hard drives and solid state drive is in the technology used to store and retrieve data. HDDs are cheaper and you can get more storage space. SSDs are faster, lighter, more durable, and use less energy.
What about other manufacturers laptops - I haven't made an inquiry about the SSD in other manufacturers laptops, but I suspect the situation will be similar. When I try and buy a new laptop a few months ago, 4 of them were SSD and in all of them despite disabling all wireless they continued to emit RF. But I didn't contact the tech departments and made a thorough inquiry as I did this time.
What to do? Buy computers with Serial Advanced Technology Attachment (SATA) drive.
