I. Introduction
Two days ago mushroom bought a surveillance camera, focusing on taking care of their own car downstairs, usually the car parked downstairs always feels not so safe, before the rear of the car always inexplicably appeared some traces of other colors, very unhappy.
But check the property surveillance video also need to open a certificate, watch the monitoring is more troublesome, very waste of time, at least to delay a morning time, and then have to find the license plate number, and then communicate, the efficiency is too low. I thought, otherwise, I can monitor it myself, it will be much more convenient to check my own monitoring, and then I bought a surveillance camera and put it by the window.
After the surveillance camera arrived, it was embarrassing, the TF card in the mushroom hand was 64G, 128G, 256G, but the surveillance camera only supported 32G at most, which was very uncomfortable and had to be bought again.
Then, under a selection, I chose a HIGH-SELLING, RELATIVELY CHEAP PRICE, BANQ's JOY JD.com co-brand card.
Second, banq driving recorder monitor TF memory card unboxing
▼ The packaging of TF is very simple, it is a piece of cardboard.
▼However, this piece of paper is very beautiful, red and white color, and there are some parameters of the TF card on it.
▼In addition, this memory card should be specially customized for driving recorders and monitoring, and optimized for high-intensity reading and writing.
▼ On the back of the package is some information introduction, including some capacity information.
▼ TF is stuck in a plastic shell, which is sealed in a cardboard sheet, and it takes a little violence to try to take it out.
Third, the Banq driving recorder monitors the appearance of the TF memory card
▼ The appearance of the memory card is very beautiful, red and orange color, there are various information about the memory card on the front, and JD.com's JOY, which is very good-looking. Look carefully at some of the labels on the front of the TF card, the capacity is 32GB, and the speed labels are A1, U1, C10, V10, etc., and it seems that the speed performance is OK.
▼ The back of the TF card only has contacts, and there are no other silk screen prints or the like.
▼ The rear of the TF card is slightly higher, which is convenient for inserting and removing the TF card.
Fourth, the Banq dashcam monitors the TF memory card for testing
▼ Ready to test it simply, with chuanyu's card reader.
▼ The size of the TF card is very small, it is easy to insert it, and it is necessary to rely on the small steps at the end of the TF card to pull out.
▼ The nominal capacity of the memory card is 32GB, and the actual capacity is about 29.1GB.
▼ The default file system is FAT32, ok.
▼ Personally still recommend exFAT file system, but this still depends on hardware compatibility.
▼ Simple run a test, the test file size is 1GB, the sequential read speed is 77.9MB/s, and the write is 40.38MB/s. oh? This performance is very good! You know, the price of this TF card is only about 10 yuan, which is very cheap.
▼ Then switch to the DiskMark test, the test file size is 1GB, the sequential read speed is 78MB/s, and the write speed is 62MB/s, and the performance is very good.
▼ The test file was replaced by 8GB, and the sequential read speed and write speed were not reduced at all, and even improved a little, which was amazing.
▼ Finally run a 20GB continuous read and write, the write speed fluctuates around 40MB/s, and the read speed is stable at 80MB/s, which is a very good performance.
5. Summary
Very surprised, this Banq's Jingdong Joy co-brand card TF card is so cost-effective, the price is only more than ten points, but the sequential reading can go to 80MB/s, the write speed can be stabilized at more than 40MB/s, the performance is still very strong.
This kind of writing speed, coping with normal 1080P video recording, 2K video recording is still very easy. In terms of driving recorders, front and rear double recording can also be easily supported. In addition, the reading speed of this card is not slow, it can be stable 80MB/s, and daily video export will be quite fast.
I just don't know how the life expectancy performs, and I have to keep looking at it. However, this TF card has been said to be dedicated to monitoring, compared to its optimization for high-intensity continuous reading and writing, it should not be too worried.
Thank you!
