if you buy new nvme's ssd just look at power consumption specs
For example:
INTEL 760p Series SSDPEKKW010T8X1
Power usage: 0.01 watt
Standby usage 0.005 watt

SAMSUNG 960 EVO MZ-V6E1T0BW
Power usage: 5.7 watt
Standby usage: 1.2 watt

and who would have thought why samsung i so drainin' battery...

Haven't seen many posts about the 760p... anyone able to chime in?

Those numbers only apply when LPM or APST are in effect. You have to read the reviews to see what the actual power consumption when LPM not active. From what I have seen so far, only MydigitalSSD is the lowest since it uses only x2 PCIe link, everything else will cause your battery life to take a noticeable hit.

About about the Kingston A1000, another x2 SSD? On their site, they list power consumption as Power Consumption:
0.011748W Idle / 0.075623W Avg / 0.458W (MAX) Read / 0.908W (MAX) Write; not sure which number to use to compare to what people are seeing for the MyDigitalSSD.

Well I have bitten the bullet and gone ahead and ordered myself a raspberry pi from ebay and one of the clips (4.0.2) from Ghostlyhaks. In the mean time I have noticed my macbook doesn't drain very much at all with the Toshiba XG5 installed with the newest (10.13.5) bootrom installed. Of course I did do a fresh install of the OS and restored my files from the original SSD (I have a usb adapter for it). Shut the lid after ordering pizza (LOL) on the macbook when friend turned up, and the battery was at 100% this morning - surely it had to have drained some during the first phase of sleep! I will use some guides from Ghostlyhaks forums for setting up the flash environment on the pi, but rather than trying to remove an icloud lock, I will be following in Gilles_Polysofts footsteps and flashing the modified bootrom that way.

The raspberry pi was $100 from ebay (AUD) and the clip about $40 (USD --> AU Peso conversion). These clips service a lot of macbooks, so it won't be wasted on just the one. Also look forward to fooling around with the Pi for other tasks such as running my inverters and solar charge controllers.

Can you make understanble step-by-step guide how to perform this flashing with rasp pi after?

Yeah be happy too, its pretty similar to what gilles_polysoft did with his flash programmer, except the rasp pi has a disk to store efi files on, and you can pull and push read/modified roms to the pi via scp, and execute the necessary commands via ssh.

I'll first read the rom with dosdudes tool, bring it across, then pull the rom with the pi, and see if the md5's match.

I just messed with mine - the eeproms did not match between the dosdude tool and a direct backup. But I flashed a rom I made based on the dosdude backup anyway. Everything seems to work fine. I imagine some minor variables get altered during shut down.

I do wonder if as a workaround we could use something like rEFInd to load the proper driver before booting the OS.

Nobody has tried it out yet, if you feel adventurous, you should try it out and report back to contribute. I hope Kingston's firmware is more stable and don't have the wakeup bug as MyDigitalSSD, that's the only thing preventing the MyDigitalSSD from being the ideal choice for battery life conscious crowd.

Sorry, can you repeat what the wakeup bug is? I've been trying to read every message on this thread, but I must have missed that one. I was definitely leaning towards the MyDigitalSSD for price and power issues, but the Kingston is price comparable and a somewhat "bigger" name that perhaps has more support muscle behind it. Thanks.

Thanks.

Also important to the E8 platform's overall idle power consumption is how background processing is handled. When idle, the drive will periodically wake up to perform background processing such as garbage collection. For the first few minutes after the drive is powered on, the interval between those wake-ups is 0.8 seconds, then the drive slows to waking up once every 5 seconds. These wake-ups continue whether or not the drive has background garbage collection or SLC cache flushing to do. Since the drive's power spikes to just over 1W during these active periods and they last for about 200ms each, this increases the overall idle power draw by more than 20%.

I hope the Kingston doesn't have this bug

Nope that won't work, as soon as the system hibernates, refind will loose control of the booting process, and the driver wont load when the machine tries to resume from hibernation, crashing the system, and it will reboot again, performing a normal bootup through refind. Somehow the driver needs to be incorporated into EFI, and the only current way you can do it is by hacking the bootrom/efi chip then flashing it with a pi or similar equipment. The pi is the better way to do it as you can do it without the laptop being tethered to another computer. I will be testing with a pi zero W, to see if I can make it really cheap to do. Pi zero W's are only $20 here in australia, so probably cheaper to get over seas. A pi bakery script prepares the SD card, and you insert it into the pi, it boots, connects to your wifi with a static ip address so you can find it, installs flashrom and its dependencies then you SSH into it ready to perform the operations.

Ah I figured something like that would be the case.

I've got an SPI programmer that works fine for this (just flashed my 2012 rMBP EFI w/ the 2013 wifi driver and flashed my 2014 with the 2015 NVMe driver successfully), but it would be nice to have a pure software solution. I've got a rasberry pi lying around somewhere too, I guess I can give that a shot too for ***** and giggles.

Might have to look into finding the flash routine and bypassing the signature check too. Would be nice to be able to update to modded scap files without having to disassemble / reassemble whenever Apple releases a new EFI.

finally
upgraded my MBP mid 2014 15" to intel 760p 1tb ssd with sintech black (long) adapter


everything looks goods, no problems. Restart, shutting down works perfect. I do not have bootcamp so can't test problems with that.
Tonight I will do long sleep for Mac and in the morning will see...

How's the battery consumption?

That would be nice, it would save pulling out 10 screws, disconnecting the battery, getting the fiddly connector onto the diagnostic port, triple checking the wiring, etc.

But now the secret is out, and its easy enough to do (and the equipment to do it is common place), it should take all of 20 minutes to fix Apple's stubborn-ness of not giving these machines the upgrade in lieu of making us buy even more upgrade unfriendly machines. Heck I could store a pi zero W, wifi pocket hotspot, usb stick and the flash cables in with my usb -> sata cables that allow me to look at other hard drives, and my HDMI cable to plug the machine into a bigger screen. The power adapter for the mac is more of a nuisance to carry than those items. A power bank in my backpack can power the pi when its needed, it'd provide plenty of juice for flashing the bootrom. Mod the bootrom, SCP the modified file to the PI on the mac, then a quiet spot located to pop out the screws, dislodge the battery connector, plug in the pi, and use the ipad to SSH in and run the flash commands (that could theoretically be scripted).

A software solution would be good though - save a lot of messing around.

with the naked eye it's look like it's not drain faster than original ssd in usual scenario (browsing, youtube etc...) but i will test it more accurately in next days. And in usual use scenario it's absolutely not heating

Guys i have a question: how is conditions to force computer to hibernate? This night i was
switched to sleep my MBP and it was in sleep more than 6 hours and woke up without any problems. So i think it was not go to hibernate because my magsafe was plugged in am i right?

update:
so today morning i plug out magsafe then left my macbook in sleep and go out. When i came back right now (after 10 hours) i hit space (like i usually do) and macbook awoke without any problems or any kernel panics etc. From start of sleep battery was at 73% and when i awakened MBP it shows 68%. So it around 5% for 10 hours

Soo my question is open: how to get error from deep sleep?

hi everyone. since my MBP is an late 2013 (core I7 2.8/16gb), and already on the latest high sierra version, I have the choice either to buy an auro pro X, or.. a newer from any vendor, but I'll face issue with hibernation, am I right on the current situation? an old samsung sm951 wouldn't change anything (I mean, since I have only 2X pcie lane...)?

hi, bro. Excited to heard your experience, I really wanna know about the power performance of intel 760p because my battery life decline nearly 50% after upgrading 960evo. And I wish you could install 'Battery Monitor' in Appstore and check the power usage while staying at desktop doing nothing with 50% brightness (960evo is about 7watt). Thanks a lot ! !!

So just did this to mine. Used an HP EX920 1TB drive

Drive installed and flashed the firmware w/ the 2015 NVMe driver:

Restored my backup and everything just works. No delay when booting, detects as an internal drive, etc.

Wow, You mean you can hibernate your MBP2014 mid from now on?
How did you do that? Do you have a SPI programmer?

Yes he/she used a programmer - you can see it and the clip on the right hand side of the first photo. It presently is the only known way to flash the bootrom with a hacked/modified one in these machines.

My raspberry pi zero just turned up yesterday - it cost $38 all up including a little adafruit protective case for it. Its presently sprouting f/f connecting cables for the ghostlyhaks clip, ready to do its work on the macbook.
