Transcend launches JetDrive 820 PCIe Gen3 x 2 SSD for MacBook Pro/MacBook Air

The PCIe 4x NVMe drives are definitely faster. Though it seems you sacrifice some battery for that

This is bus limited too. If this macbook supported PCIe 3.0, I'd get somewhere around 3200 read and 1800 write

I wish I could get that thunderbolt enclosure without the drive itself

The JetDrive 825 enclosure looks like it's meant for Apple SSD's (I guess?) or the JetDrive 820. Were you looking (like a lot of people) for an enclosure for a standard PCIe NVMe SSD instead?

No, I just upgraded my Macbook with an NVMe SSD, and now have a "512GB" proprietary Apple SSD that's collecting dust

Yeah that's an option and probably what I'll end up buying. Thunderbolt would have been nice for the speed since the PCIe SSD can saturate the USB 3 bandwidth.

The specs for the JetDrive 825 says it's Thunderbolt 1, PCIe Gen3 x2. In my 2014 Mini (PCIe x2) with a x4 NVMe SSD, I get mid-700 MB/s read/write. That seems to be what MBP's with the x2 (AHCI) interface get as well, but people with the 1TB SSD are able to get close to 1000 MB/s in the pre-2015 MBP's. So, the 825 enclosure should be faster, but not by a 2x+ multiple (unless one has the 1TB SSD, which may approach the TB1 speed). I don't know what type of speed the OWC enclosure gets.
