I’m thinking about getting one of those cheap Chinese ssd from ebay and plug it with an m.2 to u.2 adapter and a cable that needs a sata power cable.
On the drive label I’ve noticed that it need 12V and 3.3V.
My idea was to use a PSU with a molex connector that has 12V and 5V.
Is the 3.3v required or will the drive step-down the voltage internally?
Is for a R86S mini PC so it seems like an overkill to get a full PC PSU for just a 3.3V line at 1mA.
You’ll probably burn up the drive that way. Over voltage / over current! Best to just go with a sata power connector if you don’t want to cause damage / fire hazard!
Don’t feed 5V where 3.3 are expected, you will blow it up otherwise.
I just got the intel D7-p5600 ssd 6.4TB. for $359.
Reviews of most consumer SSDs said that they were able to sustain peak throughput for less than 10 seconds before falling down to 300MB/Sec. Reviews of this say it does between 5GB/sec and 7GB/sec over pcie4x4 and never drops down to a lower speed. These drives are rated for 5 years at 3DWPD. Hopefully I will be able to tell after receiving the drive, and will report here. Instead of searching for a specific model, search for “u.2”, or “u.3” on amazon, there are less than 5 pages. I also set the constraint of $150 to $900 as there are many new drives of this type still for sale around $5000.
Yeah, do not put 5v where 3.3v is expected LOL
Yeah it needs the full 5 pins on the SATA power adapter - not many drives do, but when they do, they really do. As does my weirdo EVGA sound card, which uses a SATA power connector and does not work if I only use a 4-wire extension.
Thanks for the answers. My plan was never to feed 5V into the 3.3V but wondering if it could work without the 3.3v.
The drive arrived and it works perfectly with a sata connector that only has 12V connected to it. The sata connector goes into the U.2 cable. I’m not 100% sure but I think it draws the 3.3.v from the U.2 connection that comes from the the m.2 slot.
u.2 devices need either 12v or 3.3v. The molex that can supply 5v can probably also supply 12v.
