View attachment 961187 Good evening, I'm new in the forum, congratulations on the discussion... Do you think this ssd can be good for the NFHK adapter? Thank you in advance

It will work. Although you need to be careful with kingspec, some of it shipped with a chipstar controller who tend to die without any warning. Better get SN520 from WD or use long SSD instead.

Hi guys!
I have the same problem... When I shutdown the MacBook Pro 2017 (A1708) with the charger plugged in and try to turn it on with the charger it just don't detect the SSD and my MacBook Pro won't turn on... Any suggestions to solve this strange issue?

Im using the NFHK adapter and Sabrent Rocket 2242 512gb.

My MacBook turns on without any problem if I don't have te charger plugged, and it also turn on if I unplug and plug it again.

Any suggestions? thank you!

Hi everyone,

Thanks for all the work in this thread. I am trying to follow but it's too much information to comprehend. I'm wondering if you could help with my case.

I have a 2016 nTB MBP 13 with the 256 GB drive. Currently I'm getting 2300 MB/s and 1300 MB/s read and write speeds respectively. I'm looking to upgrade to a 512 GB or 1 TB drive. Is there any consensus on the best adaptor and 2242 drive to use? Any issues with slow DRAM-less drives? Could I expect the same speeds of a stock 512 GB or 1 TB Apple SSD, so ~2500 MB/s and ~2000 MB/s read and write speeds? Does the adaptor and 2242 drive fit like stock?

Thanks.

I've been using NFHK for around half dozen of nTB macbook, and all work just fine. Can't comment about other brands, since i havent tried it for this particular model.

It will fit like stock when paired with 2230 or 2242 SSD. Although you rarely got an ssd with high speed spec in that short form.

If you use ssd with higher rated spec, you can get up to 3000+ on read and write. Although it seems generate higher heat as well.

My suggestion would stay with an SSD that rated around 2400-2600 Mb/s , better if it has DRAM, but you wont notice a difference in daily task even if you use DRAMless one. You'll only notice a drop in performance with DRAMless SSD if you continuously writing or dropping high size or plenty of data into it.

If you worry about temperature, install mac fan control to manage your fan speed better.

One think for sure is that it's about compatibility with the SSD itself,

You gonna need to do a bit of trial and error with multiple brand and models,

from my experience, surprisingly, the one that doesnt have this issue are mostly a midrange budget SSD namely :

XPG SX6000 Pro
Biostar M700

HI otosan, I‘ve read here that the nvme ssd that work best with the adaptor on MacBook A1708 is the WD SN520 2242, no hibernation issue, etc...you think that the WD SN520 in 2230 format work the same as the 2242? I’m waiting delivery of a sabrent rocket, but it seems that this ssd have some issues, so I’m thinking to return the sabrent to pick the wd sn520 (2230 or 2242).

thanks in advance!!

SN520 should work just fine in term of proper fit, the only downside is it's lower than stock read and write speed. It can only hit 1700 at maximum read. But thats common for all 2242 form, mostly come with M+B key socket (which indicate it has older/lower speed spec)

Other drive i found working fine with no charger issue is Hynix BC511 and Netac N930s,

Hynix one can hit 2100Mb, while Netac is on par with SN520 and its cheaper (at least in my country)

Dear Otosan, thank you for your valuable advice. I have actually placed an order for the 1TB Sabrent Rocket on Amazon yesterday but since it hasn’t arrived my forwarding address yet, I have cancelled the order since I have been reading many issues about hibernation and charger issues with this SSD.

The 512GB Netec SSD seems like a cheaper alternative in my country. However, the ones available to me is the Netec N930ES but you mentioned N930S. Is there any difference ? Because I can’t find any info on the N930S though.

Have you personally tested the NETEC N930 2242 SSD? I understand the speed is lower but I just use it for documents and excel. Just need a bigger capacity though.

Thanks again!

is the WD noticeably slower than the sabrent in terms of speed in real life use? My stock Apple 128gb ssd hit only 750mb in write speed, up to 2000 in read...

I’ve just mounted the sabrent nano, everything works fine, speed performance around 1600mb write and 2100mb read. the only issue is the question mark when booting with the ac adapter plugged in.

The nano being 2242 or the 2230?

I installed a Sabrent 2242 500GB 3 months ago and have had so few issues. I have had that flashing question mark a couple of times, but not sure if it always happens when booting plugged in. Just so easy to boot with ac unplugged. I rarely boot the laptop anyway.

2242 1tb...it seems the this is the only issue at the moment...the next week I'll buy the WD SN520 to test how it works

Hi all,
I just wondering if it is ok to use a 2280 size at all or are people getting problems using them, I know it will be a bit of a "hack" job, but the pros seem to outweigh the cons.

The SSD i'm looking to use is Samsung 970 EVO 500gb 2280

Yes, i personally installed NETAC on few of my customers A1708 , all work great without questiin mark issue nor sleeping issue. Only cons is, stock kinda limited.

2280 is fine as long as you know what ypu are doing, and do it properly,

just dont use samsung, it's way too hot.

Please let know how the WD SN520 compares to the Sabrent

I just connected my MacBook AC adaptor in my USB-C hub which has a type C port for power delivery, no question mark when boot via usb c hub

I have an OWC Thunderbolt 3 Dock and will try powering the MacBook through it and see if it avoids the problem too. This is a curious solution and the only reason I can think is that maybe the hub puts through slightly less power than directly powered to the socket?

Personally the only advantages I see is the slightly cheaper cost and better availability of the standard 2280 size, but the installation is a total hack as you can see in the video I posted on the 13th of May (Post #15) and can have no advantages for heat issues and the durability of the SSD as well as forcing the back plate of the laptop. These are costly machines and I think, personally, not worth saving a few $ - I would go for a 2242.

I also concur that Samsung is not proving the best match, there is a list in several placed of 2 or 3 Samsung NVMe that are proving incompatible in general with Macs. Though I do not now remember if the 970 EVO is one of them.

I thought the same thing...since the power socket is plugged through the hub I haven’t seen the question mark folder anymore

I wonder if some one can give a more technical explanation, I can only see that there could be less power.

Do you know how many watts your USB C hub passes through? I have the first version of the OWC Thunderbolt 3 Dock that passes through 60W.

it’s an Asus Mini Dock type C, I’ve read the specs but nothing claims how many watts passes through the power delivery port

I report some thoughts about the sabrent 1tb nvme ssd coupled with the NFHK branded adapter. As someone else report, the sabrent seems suffer of throtthling, I’ve tested the ssd’s speed when freshly installed the OS, and the w/r results were 1600/2100. After the installation of some of my main apps, I’ve repeated the speed test, and the results were 490/1900. I called this issue “throttling”, but I’m not so sure, ‘cause I’m not a technician, so if someone with better knowledge about it can chime in and explain this, is welcome.

For charging, the hub should pass through the same amount of power as it needed by the unit, else it would be problematic. So i dont think it's power issue righ there, especially when its not happening on every ssd.

Hi ritchie69,

I have a same problem, my first installation was done with time-machine backup. When I found out that write speed is around 400mb/s, I thought that reason for this is because I used time-machine backup. So today I erased my disk and tried to do clean installation and guess what ... yup same problem.

My last guess why is this happening is because when I've been removing the original Apple SSD from a socket a removed that black tape in the way it was not possible to stick it back. Also I discovered that when I let Macbook to cool out, set fan to the max and then I tried disk speed I discovered that the write speed is instantly kicked to the 1,3gb/s and slowly decreasing to the 600mb/s and the with next try it sits on 400mb/s. This looks like the thermal problem and reason why the write speed is limiting is MAYBE because of the missing tape ?

Don't know ... did you removed that tape too ?

Arcius, I don’t think the low speed it’s thermal related, I guess it depends from the SSD’s cache, I’ve read that when the cache is full, the performances will go down quickly. Also, I‘ve made a speed test when the Mac was just turned on, and it was cold...I replaced the black tape with a thermal pad.
I discovered the disk slow performance after installing the apps, but the first test was done with the empty ssd, just the OS, in that case the speed was good, let’s say 1600/2100.
anyway, I’ll try to reproduce your test with the fan at maximum, I hope you’re right!

I dont think thats due to thermal, but due to your ssd cache filled up.

You dont have to continuously run the speedtest, run it for 1-2 times is enough, since thats how likely u will used your macbook in daily task,

unless you copying and extra big file continuously, your cache shouldnt filled up that quickly.
