While I have had very positive experiences upgrading my 13" Late 2013 MBP to an nvme 1TB Adata SX8200,
I have had a very frustrating time upgrading my 13" early 2015 with 2TB Sabrent Rocket nvme SSDs.
Right out of the gates, kernel panics every time it would sleep.
Ran hot.
Tried a new short Sintech adapter. taped it.
Tried a new long Sintech adapter.
The kernel panics just kept getting worse.
Moved the drive and adapter, to the Late 2013 MPB and the problems followed the drive.
And the drive got worse and worse to the point where it would KP if you looked sideways at it.
Ergo the drive is faulty.
So I ordered a second 2TB Sabrent Rocket.
Initially: problem solved - 3 days of bliss free operation -- no kernel panics, no sleep or hibernation issues!
Seemed to run cooler too
Was about to post about it...
And the drive died. Non responsive, does not show up for love or money.
Dead.
So now I have a 2TB Adata SX8200 Pro inbound.
I hope "that the third time is the charm", and that by bad luck I just encountered two bad Sabrent drives.
