should be good for 1300 - 1500 r/w speeds with a reasonable 4 lane ssd
Someone else here mentioned this one which seems to be a good price.

should be good for 1300 - 1500 r/w speeds with a reasonable 4 lane ssd
Hello. I need more space in my MacBook Pro 2015 i5 2.7 16GB.
Now I have 128GB (original) SSD, but I decided to upgrade it to 1TB. I really need good battery life, write/read speed is not so important for me. Can you guys can help me, which SSD is the best for battery? Are they all worse than original from Apple? :/
Thank you for your help!
How's battery life compared to before the upgrade?Six months later report
- Original: Macbook Air 2013 13" 256GB SSD 8GB ram
- Upgrade: Adata XPG SX8200 1TB (not the Pro)
- Adaptor: Short adaptor with 183307 stamped on it, and on the green circuit board it says NFHK N-941A. (Possibly no longer available). Purchased from Amazon UK.
All working fine. Macbook Air far, far faster, far more snappy, far more usable after the upgrade. Occasional black screen / force reboot on waking. Especially if battery is under 5% when putting to sleep.
Old Apple SSD: around 400MB/sec
New Adata SSD: Around 1300MB/sec

Important comment on the Adata SSD especially degrade in performance when filling up. To be expected but good to be aware.

Next project:
I've just got a 2015 MBP 15", 16GB ram 512GB Apple SSD, 700MB/sec.
Feels 'slower' than the Air, even though the MPB has an i7 & fresh OSX install and the Air has an old undervolted i5. It's all because of the SSD (!)
I have a new Crucial 1TB CT1000 P1 which might be slower than the Adata. Considering moving the 1TB Adata to the MPB and putting the Crucial in the Air, but it's a lot of hassle.
I have a spare short 183307 adaptor (accidentally brought two last June). Any updates on adaptors? if not, I will use that for the MBP.
intel660p should be good for you
What about sabrent sb rocket, because Intel 660p is QLC and I read that this is not like TLC.
As far as I can tell, about the same. Functionally a little bit less because I have to be more careful now about not letting it go under 5% while asleep if I don’t want to loose unsaved work.How's battery life compared to before the upgrade?
Thanks for your comments. Could you post some iStats screenshoots to have a look at power consumption?As far as I can tell, about the same. Functionally a little bit less because I have to be more careful now about not letting it go under 5% while asleep if I don’t want to loose unsaved work.
Overnight it loses a couple of %, but quite minimal.
After doing some digging in the Apple supplied EFI tools, Ihavehad a strong suspicion it should be possible to develop a software-based solution to flashing a modified bootrom that should fix the Late 2013 hibernation issues.
Some users reported to have achieved this successfully around November/December 2018, but their guides or information are incomplete or don't deliver the desired results anymore.(https://apple.stackexchange.com/que...use-of-a-sintech-adapter#comment444229_333495)

Modifying the firmware updater is very similar to modifying the extracted bootrom image (through hardware extraction with a CH341A or /usr/libexec/Firmwarecheckers/eficheck/eficheck). The main difference is you're changing an firmware updater file, and not a rom image from the chip. The chip files use rom or .bin.
- Extract the latest firmware updater file for your specific MacBook from the a Mac Install.app(Open Contents->Contents->SharedSupport->InstallESD.dmg->Packages->FirmwareUpdate.pkg->Scripts->Scripts->Tools->EFIPayloads). For my Late 2013 it was MBP111.scap
- Extract the firmware for the 2015 Macbook. For my 13" Late 2013 I used MBP114.fd
- Use UEFITools 0.24 to extract the NVMe driver (GUID
51116915-C34B-4D8E-86DB-6A70F2E60DAA) as a separate file from the MBP114.fd, I named it DXE NVME2015, and the added extension was .ffs- Execute a "Replace as is" on the NVMe driver in the MBP111.scap and replace it using the DXE NVMe.ffs file
- save the firmware updater file, and you could be required to rename the extension back to .scap
- Use terminal and execute sudo /usr/libexec/efiupdater -p /Path/To/Folder/Containing/fixed.scap --force-update
- This should pre-stage the EFI firmware and write it to the EFI partition with bless -mount / -firmware
- According to the users reporting success, if you'd shutdown the Mac, wait a few seconds, and turn it back on, it should go to a grey screen and a progress bar, indicating it is flashing the pre-staged firmware update to the actual bootrom. Actual quote from second link above: "Shut down your mac from menu, wait until it will turn off.
Wait a bit, then turn on your computer but do NOT hold the power button down. The screen will turn black and remain in that state for up to 40 seconds. A gray screen will appear and a status bar indicates the progress of the update."
Until step 8, everything works and gives good outputs. I can see the changed firmware in the EFI partition. It just doesn't flash it when booting the first time after it. I've tried running the efiupdater from recovery as well, not different results.
For now I'll flash my MacBook tonight with the CH341 and Pomona clip I have waiting at home. But I'm sure someone with a bit more knowledge can fix this method too, and save a lot of people the risk of flashing manually.
=====EDIT=====
After some more testing, I tried to pre-stage/flash an unmodified MBP111.scap to my Late 2013. Same terminal response, but it DID flash it with a visible progress bar when rebooting afterwards.
So:
There is probably some firmware signing taking place, meaning this would never work.... Maybe it's been added since Mojave, leading to some users being successful previously
Hi, i'm having a problem when i try to connect the ch341a to my secondary mac... it doesn't recognize the chip and i don't know where to find drivers of it, how can i ask you some questions about it?
Thanks
brew install flashrom
flashrom -p ch341a_spi -r dump1.bin -c "MX25L6406E/MX25L6408E"
The only downside are the kernel panics which occur.
They seem to occur when my macbook is in hybernation and password locked on.

They seem to occur when my macbook is in hybernation and password locked on. I tried disabling power nap and put ssd in sleep when possible. Still doesnt work. I tried a reinstall of the soeftware but no luck either.
Im out of ideas.
do a pram and smc reset see if that helps.Hi @All,
meanwhile my "short" sintech adapter has arrived, together with the adata 8200 pro in place insde my macbook pro retina 13" early 2015; hdd clone installed - and - it works finally. As well as without the "bulge" on the backside as with the usage of the "long" adapter.
And yes - temperature is getting higher than with the original apple sdd - but seems not to be an issue so far - but:
My macbook has slown down significantly - at startup and also at startup of simple appes (like safari etc.).
Quick test with an SDD test has shown writing speeds up to 1.300 MB/sec and reading speed up to 1.500 MB/sec (with 5 GB files).
Does anybody of you guys have an idea what could have gone wrong?
BTW - "FileVault" is still off - I did not change anything in the configuration.
Thanks in advance,
Carioquinha

How’s battery life after the upgrade?Hey guys,
I don't have any idea - but after formatting the SDD again and installing the same clone as before - the system seems to be working well...anybody with an idea why?
Cheers,
Carioquinha
Hi,Looks like it panics because of nvme driver or something related. What version of bootrom your mac has?
I did some research and found that bootrom 188.0.0.0.0 is available for my macbook.
