I'd like to upgrade the M.2 SATA NGFF style SSD in my Dell Venue model 7140 tablet/laptop to a 512GB or 1TB but am having trouble finding any M.2 SATA SSDs of any capacity from a decent brand. They would need to be 2230, 2242, or 2260 size. All I'm finding is tons of AliExpress/Chinese knock-offs. Don't get me wrong, I know they're all made in China, but there's a big difference in the decent name-brand stuff from a reputable manufacturer and the KingGamer, KindData, KingSpec. Does anyone know anything about the Transcend brand?

WD still produce them at least under the blue/red labels. You might also find some crucial MX500 kicking around too.

Do you have any links? Because I can't find any information on either of their sites for current devices that meet my needs, nor can I find anyone selling them, anywhere. From what I can tell, neither of these manufacturers make much of anything other than NVMe drives, which are not compatible with my system and were not what I was asking about. I need specifically a drive that is SATA and has B & M key connector and is 60mm or shorter. I did see a couple of SATA NGFF type drives on the WD site in the series you mentioned, but only in 80mm, which I can't use and wasn't asking about.

Thanks.

I checked the interface rather than the length the WD's are 2280. Looks like you may well be life with junk drives then.

Yeah, that's what I was concerned about.

Transcend and Silicon Power are two brands that seem to be regarded reasonably well in the user forums.

Yes, I've found a 1TB Transcend of the right type, a compatible size and a decent price. I think I'm going to give them a try. I'll look into Silicon Power as well.

Thanks!

For the record, I couldn't find anything made by Silicon Power other than 2280 drives. I ordered a Transcend 1TB M.2 SSD 430S.
