What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Acer Aspire Revo R3610 WiFi Aerial Mod

I've hacked together a cheap and easy fix for the poor quality signal received by my internal WiFi card on my Revo 3610. As usual a video says a thousand words - but the picture above will have prematurely given the whole game away if you know anything about what sockets do and don't belong on a Revo.

Edit - (Update)... I thought I should mention that the reason I am sticking with the internal card rather than just using a USB WiFi dongle is because my internal mini PCie card works on the 5Ghz band and I can't find a 5Ghz dongle.

Wow that was quick work, I'm happy that you found this useful. I think that the wifi signal gets blocked by all the metal shielding inside the Revo. Please report back about how you got on.

Hello, I want to try this. It looks like the wireless card upgrade you did to the BCM4321 supports around 270-300 MBPS. Does the wireless router you use depend on whether you can transmit these speeds. The router I am using is

The issue I'm having is on my download speeds only get up to around 4 MBPs on the revo, while my desktop through ethernet gets around 25 MBPS. streaming video and downloading is slow and choppy on my acer revo. The wireless modem is only around 10 feet from the acer revo with no obstructions. Wondering if the attena mod along with replacing the wireless card to the BCM4321 will do the trick? If i do this might also be a good time to upgrade the 2 gigs to 4. Has anyone done this and seen worth while improvements. It's the 330 atom processor.

Unless I'm mistaken - that router is 802.11 b/g only and therefore there would be no point in upgrading your Revo to 802.11n because it'll only run at 802.11g speed.
I'm not too sure what speed you should be getting from 802.11g - but 4mbps might actually be normal.

If you are getting a good signal then there wouldn't be much point in adding the external aerial either - sorry I couldn't help more - maybe someone else could comment here with some advice.

Hi, i am looking at doing the same modification to my revo, i am having trouble finding the mini pci-e card wolud you please tell me where you brought yours from. Many thenks

No problem - just search Ebay for the following item "HP BCM4321" - you will find a number of people in HK/China selling them for approx £15. These have been pulled from Laptops and are in new condition. I have no idea why they have so many of these for sale. This is how I got mine.

Hi As for the Aspire Revo R3610, Did you experience in very slow in viewing online/internet tv programs, surfing the internet, etc?? I have 4GB RAM installed and running WIFI 802.11n
Hope u all can share this info. Thanks.

Hi Tom.
I have the same computer (R3610 with 4GB) and exact same problem. All browsing/downloading very slow compared with my laptop (which has less RAM and lower CPU) even though the signal strength is good

Acer just say to restore to factory settings, which means days spent reloading everything and may well not fix the problem. Any better ideas please anyone. Please.

I've got to say that I haven't experienced this (yet). What OS are you using?

July 1, 2010 | Unregistered CommenterTechmoan

I bought Revo couple of weeks ago. They have now upgraded the wireless card (with draft-N capability). But seems like it can only detect 2.4ghz signal, I have Dlink DIR-825 Quadband router with 2.4ghz and 5ghz dual access points. Even though my older laptop is able to detect the 5ghz signal, my revo is unable to do so (2.4ghz n signal is working fine). Any ideas or solutions to make it work ? Has anyone faced similar problem ? Thanks.
