Blackvue DR650S-2CH Power Consumption

I've tested my new dashcam for current consumption.
Tests were made at my desk with lab power supply B&K Precision 9110 connected directly to the cam.

Setup conditions

1. GPS is on but in a building it can't acquire satellites.
2. Firmware v1.000-EN that came out of the box. Few measurements were done with v1.001-RU - current looks the same.
3. Cloud service not set and not used.
4. Memory card from the package: Blackvue 16GB CL10 MLC.
5. Disconnecting/connecting rear camera done during full power off
6. Measurements taken at stable mode: 1 or more minutes of working in that mode.
7. Power on measurements was done with charged supercaps, no long power off stay.

From the manual we have these numbers

1. Avg. 400 mA (4.8W at 12V, when GPS and WiFi is On)
2. Avg. 300 mA (3.6W at 12V, when GPS and WiFi is Off)
3. Actual power consumption may vary depending on use conditions and environment.

Test condition		14V, mA engine on	average		12V, mA engine off	average
Power ON		460 (peak 500)
Power ON		450 (peak 660)
Front		180...220	200		220...260	240
Front + WiFi		200...250	225		240...290	265
Front + Park		140...180	160		180...230	205
Front + Park + WiFi		170...220	195		200...250	225
Front + Rear		280...310	295		340...380	360
Front + Rear + WiFi		310...350	330
Front + Rear + Park		250...290	270		300...350	325
Front + Rear + WiFi + Park		270...310	290		310...370	340

Abbreviations

• Front = Front camera
• Rear = Rear cam attached
• Park = Parking mode activated

Memory card that was used

Conclusions for 12V usage as it more important because that is the voltage when engine is off and usage of dashcam drain your battery.

1. Consumption is bigger when engine is off, so be aware and I recommend to use Power Magic Pro with any dashcam to save your battery and shutoff cam when it comes to critical levels. Mine set to 12.0V threshold.
2. When WiFi is on it adds 30mA in idle, not used connection. Maybe it has some sleep mode with less current - I don't know.
3. Using rear cam adds 100mA.
4. Parking mode reduces consumption by 40mA.

SLC vs MLC vs TLC

Выбор карты памяти для регистратора.

Купил тут я значит новый видеорег для авто - BlackVue DR650S-2CH. Уж очень мне они нравятся во всём. Да и уже 3 раза в авариях меня выручали, старый давно уже окупился :-)
Брал на еБае за $360 с доставкой из Америки, при получении таможня содрала ещё 110 шек.

В общем, заморочился выбором карты памяти правильной. Оказывается есть неправильные! Это я раньше знал, но как-то думал, что я всегда правильные покупал. Оказалось, нет :-)

Вначале немного теории на английском, потом я резюмирую ниже.

• SLC - Single level cell provides high performance, low power consumption; faster write speeds, and higher program/erase cycles per cell, but at a higher cost. These devices are mainly used in high end server applications.

• MLC - Multi level cell provides a lower cost than SLC; however, MLC has a lower endurance limit and lower program/erase cycles than SLC, and is a good fit for commercial/workstations platforms and applications.

• TLC - Three level cell provides higher density, but has lower endurance limits, slower write read speeds, and lower program/erase cycles than SLC and MLC. To this point, TLC NAND has been used primarily in flash devices; however, technological advancements are making TLC an option for normal applications.

NAND cell technology

A single NAND flash die is typically subdivided into 512 MB blocks, and each block is typically subdivided into 4 KB pages. You can read and write to individual pages as long as they are empty; however, once a page is written, it can’t be overwritten - it must be erased first before it can be written to again. This sequence of writing, erasing, and then writing again is known as the Program/Erase cycle. The P/E cycle can serve as a criterion for quantifying the endurance of a flash storage device.

 Physically, all three NAND technologies consist of similar transistors; the only difference is that they store different amounts of charge. All three work similarily, applying voltage to a cell to go from an “off” state to an “on” state. SLC uses two distinct voltage states representing one bit per cell and two logic levels (0 and 1). MLC uses four distinct voltage states representing four logic states (00, 01, 10, 11) or two bits. TLC uses eight distinct voltage states representing eight logic states (000, 001, 010, 011, 100, 101, 110, and 111), or three bits.

Резюмирую.

1. SLC - cамые надёжные (до 100К циклов перезаписи ячейки), нереально дорогие и обычно доступны на небольшие объёмы. Используются в важных устройствах, где надёжность главное.
2. MLC - менее надёжны (до 3-5К циклов), используются в менее важных устройствах.
3. TLS - самые не надёжные (до 1К циклов), самые дешёвые - продаются во всех магазинах для рядовых пользователей. 

Вот список, который я составил по разным источникам.
В Израиле проверил несколько компьютерных магазинов, не нашёл MLC вообще. На еБае и Амазоне ещё есть MLC варианты с доставкой, ищите по кодам.
