Not bad.
I made the "mistake" (OK, I don't really know yet), of ordering FIVE "Vaseky" (which appears, from their logo, to be the new name for "V7"? Which used to produce RAM). Anyways, I bought some 128GB NVMe SSDs. Yeah, I know, parallelism and all that. I don't think that they're MLC, either. I'll find out the performance, when I get them.
At least, for budget browser builds, I can check the "NVMe SSD" box on the builds. Hopefully, they are at least faster than a decent SATA6G 2.5" SSD. They're certainly more compact.
I can also use them in my Ematic 13.3" AMD A4-9120e / 4GB / 64GB eMMC laptops from Walmart, they have an M.2 slot with an access panel. The one laptop I opened and am using, fairly successfully, I put a 128GB TeamGroup SATA6G M.2 in, but the BIOS makes reference to NVMe, and the slot is dual-keyed, so I think an NVMe drive may work, although it may be limited to PCI-E x1 speeds. Perhaps I'll test.
(Edit: Regarding the Ematic 13.3" AMD A4-9120e laptops with 4GB / 64GB. I was apparently remembering wrong, the SATA SSD that I put into the first one was dual-keyed, but the slot was not, and I couldn't get the NVMe SSD to fit properly. Even thought the BIOS mentions NVMe. So I put in another one of my TeamGroup 128GB SATA M.2 SSDs. Which somehow, the "Master Password" got set on, from the BIOS, without me setting it. Weird. Don't quite understand that.)
Edit: I think that they were listed as SM2263XT controller-based? Which is TLC and DRAM-less? Yeah, I'm sure performance
could be better. But they were barely more than a 128GB 2.5" SATA SSD, so I consider it sort-of a "win".
These are the ones that I purchased. Mine said "Shipped from USA/Newegg". Now they say, "Ships from China". Guess I got lucky.
Vaseky V900 can greatly improve the speed of your laptop or PC while taking up little space thanks to its M.2 2280 form factor. Built with premium Micron/Toshiba TLC Storage Grains and 2263XT controller, it utilizes PCIe 3.0 x4 interface to deliver ultra-fast data transfer speed, with up to 1,322MB/s* read and up to 889MB/s* write. Now you can spend less time waiting and get more things done, as everything from boot-up to program launching becomes incredibly fast.
Vaseky V900 also runs stable. It has passed three tests including EVT (Engineering Verification Test), AVL Component Quality Evaluation and DEAM Characterization Test to give you full peace of mind.
*Speeds vary depending on system configurations.
"Storage Grains", LOL. Anyways, if those specs are true for the 128GB size too, that's actually not too shabby. 1322MB/sec read, and 889MB/sec write. Better than SATA6G at least.
