When im using my mac with the new intel drive, the battery drains much faster than it used to with the apple ssd. And I notice my mac is significantly warmer as well compared to before...
Hi Gymboy,
maybe your drive hasn't yet been finished to index..
This is very common with freshly installed OS.
You may look at "mdworker" process in the activity monitor.
Also look at any other process that uses the processor on background.
A freshly installed OS can present 20-25% background CPU utilisation for indexing purposes. You may also have some software that need to resyncrhonize data.. (e.g huge imap folders which resynchronize, or dropbox or Google drive, adobe updates etc.)
After a few hours/days, and with every software up to date and every unnecessary launchagent/daemons carefully desactivated, the processor must be at 95% "inactive"...

Very helpful thread. I am upgrading my Macbook Pro 15" mid-2014 with a 512gb Kingston KC1000 and Sintech adapter.
Off-thread :
I have a Macpro 5.1. I want to install into it the Apple propriatery SSD (from my Macbook). Does it exist an adpater to plug the Apple SSD into a PCI-e card (like a Sonnet or Lycom dt 120)?
Hi,
Yes this is off thread but this card will do perfectly the job :

It will work in any MacPro from the 2006 MacPro 1.1 to the 2012 Mac Pro 5.1.

Question:
Theres a SSD drive I'm looking at getting but not sure if i'll run into 'known issues' & what read/write speeds i'll truly get out of it.
It was removed from an Dell Alienware 17" R4, Toshiba SK Hynix 1TB PCIe NVMe M.2 SSD.
Would it be worth it to save $120 and get this drive for $360 instead of getting the Intel 600p 1tb?
.
Hi,
the 1TB NVMe drive in the Alienware should be a Toshiba XG4. $360 is quite a good price for it, and this drive has the advantage over the Intel 600P of being a little faster and able to be formated in 4K block so that it can be used back to 10.12.
Nervertheless, being it a used drive from an Alienware notebook you won't have any warranty on it...

Thank you for the constant good work!
Please add the following:
PM961 512GB MZ-SLW TLC CXY70H1Q $350 No 1200MB/s 2600MB/s No issue Yes No 6.1W
Hi
tetet,
Thank you too, I'll add it to the table !
For the ADATA SX7000NP, I got about 800MB/s read and 1500MB/s write on MBP 15 2015. However, the write is only about 1000MB/s on any other models. Could you please double check on this?
Oh.. I do apology : the test of the Adata I made was on a 13" so only PCIe 2.0 4x lanes...
So my results of 890MB/s write 1090MB/s read are quite coherent with your 1000MB/s write. You have read speed lower that write speed on the 15" ? I'll try to test on my 15" and tell you..
Furthermore, how often do you see kernel panics on Samsung drives, and what could be the trigger? I used a PM961 for about 3 months (mainly plugged in) with no issues at all.
I have tested 5 Samsung drives so far :
- a Samsung 960 Evo 512 GB
- 2 Samsung 960 Pro (one 512 GB and one 2 TB)
- a Samsung SM961 but only 128 GB (so, no daily use of this one because not enough room to have my datas)
- a Samsung PM981 512 GB
This last one was the most frustrating : I wasn't able to copy data or install a system neither do write speed tests on the PM981.. it fails... I think it will need a firmware update soon. But surprinsingly I was able to install Windows 10 and a recent Ubuntu on this same drive and with the same rMBP 13" without issue...
I'll do test on it again as soon as I have time...
About the 960 Evo and Pro, I did have kernel panics a few times, only after a few hours of intense use and with no clue to repeat the problem...
I eventually found a 100% reproductible way to have a kernel panic : do a full backup with CCC 5 on a fast Samsung T2 USB 3.0 SSD.
No kernel panics at all occured while doing full backups (400GB) from the Samsung 960 evo/pro with CCC to a slow platters HD.
No kernel panics occured while doing a full backup (400GB) from all other tested NVMe SSD (intel 600P, Kingston KC1000, Toshiba XG3/4, WD Black, etc) with CCC to the fast Samsung T2 USB 3.0 SSD (all backups did fully succed normally)
And kernel panics occured 100% of times (with the backup failing always after 30-50 GB data copied) while doing the same full backup (400GB) from a Samsung 960 evo/pro to an external fast (300MB/s) samsung T2 usb 3.0 ssd.
