128GB SD Card issues

So this turned my attention to the SD Card Adapters and their performance (or lack of performance).
I found the following:

These Adapters returned similar, lower CrystalMark Results:
OLD Thinkware Adapter
NEW Thinkware Adapter
SURPAK Adapter

These Adapters returned similar, higher CrystalMark Results:
LEXAR Adapter
ROCKETEK Adapter

Based on the Adapter findings, I re-tested all the SD Cards using the LEXAR Adapter. All Cards were tested three times, and each Card returned very similar results.

Below are the Crystal Mark test results for the SD Cards using the LEXAR Adapter:

I have tried the SanDisk ExtremePLUS in my F750 (running F770 Firmware) and in my X550 and the Card was accepted, could be formatted in the DashCam, and appears to operate correctly.

I currently have the 128GB Card in my X550, and will run it overnight. In the morning, I will find out the length of time that the Card will record in the Continuous Record Mode before overwriting. I will also sample the Video Files to see if there are any errors.

After that, I will find out the length of time that the Card will record in the Parking Mode before overwriting.

I still have a SanDisk Extreme (P/N SDSQXVF-128G-GN6MA) and a PNY U3 Pro Elite (P/N P-SDUX128U395PRO-GE) inbound from AMAZON. These Cards were due here on Monday, but were "lost" in shipment. AMAZON is re-sending the order.

Wow RG.
Plenty of bed time reading there for the technophobes and credit to you for the time and effort, give me an engine, gear box, final drive anytime !!.
I did note the comment of the Thinkware Card Adapter, I was uncomfortable using it for the first time as it felt a little rough and required more effort than expected as did the entry into the camera itself.
I would be very interested in the total recording time using both cannels using a 128 card in a 770, for whatever reason I expected more than approx. 6 hours.
To add further regard my earlier comments of getting a message "Card requires formatting" while viewing on my laptop and appearing to lose all the data (It may well have been the adapter then RG), I returned my card to the camera and reformatted, a procedure that literally takes seconds ? I only had a 30 minute journey after which I checked the recording in the laptop and it was all fine.

Max.
 
Here's an interesting wrinkle.
I RMA'd back to LEXAR the original LEXAR 633x 128GB Card that worked in my F770 for several months and then failed.
The replacement Card arrived today, and it works in both my X550 and my F770.
They must have replaced it with one of the earlier cards.
Time will tell how long this one lasts.

RodeoGeorge
 
I gave up on the 128GB. Too much hassle. I think it's a bad design to not officially support 128GB and also limit to only Thinkware brand SD card.

Just use a 64GB card and be done with it. Buy 2 and swap between them when you need.

I think this is the best solution, for now at least.
 
I agree that for those that want stable operation, and are not concerned with the maximum record time, the 64GB Cards are the way to go.
In my case, I'm on the road traveling to Rodeos, and often make a 1100 mile trip (18 Hours driving time) that I wish to capture the largest possible Continuous Recording Time. That is why I'm researching the available options.
Now, on to the latest info and data.

I received a SanDisk Extreme 128GB (Rated at 90MB/s Rear and 60MB/s Write) and a PNY PRO Elite (Rated at 90MB/s Read and 90MB/s Write)
As I mentioned earlier, I also received a replacement LEXAR 633x 128GB Card for the one that I RMA'd, and it appears to be the older version of the 128GB Card that works in our Dashcams.
I found that the SanDisk Extreme performance was very close to the SanDisk ExtremePLUS.
I also found that the PNY fell far short of it's advertised performance, but did operate in the Dashcams.

I'm not posting the CrystalMark results for These Cards, but rather posting the bottom line on them in a spreadsheet format.
And the bottom line for me is that I've found the following 128GB Cards operate correctly in the Thinkware X500, X550, and F750(running F770 Firmware).

Hi RodeoGeorge,

I have been looking into these Lexar 633X 128gb memory cards and have noticed there are two different versions, the older ones come with a usb 3.0 card reader and the newer ones come with a sd card reader.

On amazon i found the the one with the usb 3.0 reader and have ordered it to see if it will work it has a part number of,
LSDMI128B1EU633R.

The newer card has a part number of, LSDMI128BBEU633A, i believe these are the ones that dont work. Can you confirm what part number ones you use?

I have tried the samsung evo plus 128gb cards and they dont work and also tried a sandisk 128gb ultra micro sd XCI they dont work either.

Thanks
 
The LEXAR LSDMI128B1NL633R is the Card that DID work for me.

The LEXAR
LSDMI128BBNL633A is the Card that DID NOT work for me.

RodeoGeorge

My prediction is that all part numbers that finish with the A will not work. I'm from the UK possibly your part number is a different country but same principle.
 
Has anyone tried any of the sandisk extreme pro 128gb micro sd cards?

I'm currently using a SanDisk Extreme Pro 64 GB MicroSDXC UHS-I with absolutely no issues.

Hi,

I received the slightly older Lexar 633X 128gb micro sd card today from amazon, the card ending with the (R) formatted it to exfat and popped it into the F770 and guess what it works! No errors or nothing, i used the app on my iphone to format the card as well and its still all working fine.

Ive also found a place that has some the older cards and now have ordered as spares just in case one fails.

I bought 2 days ago the 128GB Samsung EVO+ card (red,UHS-I), and I have same problems with it, like Gil. First day, I formatted it to FAT32 with 32K sectors with application named Rufus 2.14. It worked, but another day just memory card error. I checked the card, it worked for few records, than the last was corrupted, and thats is. I formatted the card to FAT32 again, but this time it not helped. Then I tried to format the card with the Thinkware app, which is typically located on the SD card, it formatted it to exFAT, but no luck. Always "memory card error" with cycling restarting, or "insert memory card" announcements from the dashcam, so no chance to format the card in the dashcam. I will buy today another card from another manufacturer.

I tried that card and all I got was memory card errors, I could not get it to work at all. This old lexar 633x though works with no issues at all. I formatted the card to exfat and it just works.

Here is some info about the Samsung EVO+ 128GB microSDXC card.

Hi, I have updates. So, I just returned the Samsung micro SDXC 128GB EVO Plus card to shop, and bought SanDisk Micro SDXC 128 GB Ultra Android Class 10 UHS-I card with SD adapter. As first, I checked it in PC. The card was formatted az exFAT, but here is one detail. The first 16MB of the card isn't used (check the image). So, I made a printscreen, and inserted the card to the dashcam. No card error, so I connected thru wifi to the dashcam, and formatted the card in the dashcam. It worked without any problems.
I'm at the night shift right now, I will inform you if it fail tomorrow like the Samsung EVO+, or not.

Gil and co.: Try to format your card with first 16MB unused. Maybe it will help. :)

UPDATE: The Sandisk card after 10 hours at place with lot of motion around the car still working. :)

Hi, what a delay in my reply.

So few things:
1. Any update so far? I hardly believe that since April, you had zero issues with the 128GB. If you did, I'm willing to try it myself.
2. For the last 5 months, I was using the Samsung 64GB EVO, which also had random issues. Unlike the 128GB Samsung, this 64GB was accepted by the F770 and when errors happened, the camera would reboot and somehow would continue to work. This means I had gaps in videos... imagine that happens exactly when you don't want it.
3. I've decided I had enough and I paid $90AUD for the ThinkWare branded 64GB card.

It's MLC architecture and has 90MB/s (I believe it to be read, not write). I have this card for a week now and had zero reboots or issues what so ever. In addition, the F770 boots faster with this card.

I don't know if the 128GB Samsung EVO+ I bought on January is MLC architecture, but it's think it has similar specs as the Thinkware SD card.

One thing to note, on the packaging of the Thinkware SD card, it is stated that the card is equipped with power loss fault tolerance / ability to recover from sudden loss of power... something along these lines. I'll dig up the package and upload an image.
I do not know if it's unique to Thinkware, or if it's a standard across all SD cards.
 
This is the card I posted as using SanDisk 128gb SDXC UHS-1 in March this year, it has performed impeccably throughout to date, bought it from Argos.

Max.
