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.

A lot of wireless N cards only work on 2.4ghz, 5ghz is a lot rarer. It sounds like you'll have to restrict yourself to using the 2.4ghz band with your Revo 2.4 ghz transmits further than 5ghz anyway - so as with everything it's a trade off.

Hi Techmoan,

I took your idea a bit further. Since the wifi card has two connectors and uses two antennas for antenna diversity I removed both existing internal antennas (which are just pieces of sheet metal - those held to the casing by yellow tape) and their connectors, and replaced them with two male sma to u.fl adapters. I decided to place the sma sockets in the existing antenna cavities and I drilled the holes aligning them with the small cable notches in the metal shielding. This way the placement of the two sma sockets on my 3610 Revo is as follows: one next to the nVidia Ion label and the other on the "bottom" corner, next to the cable lock slot.

Now I can connect any two aerials and look for the best configuration. Just for the looks however I ordered a pair of those small D-link 2dbi antennas, in white - they should match up nicely with white casing of the Revo.

I have one question: How did you know this particular card that you used would work with the Revo? How do you determine wifi N card compatibility? Is there a guide you can follow?

The WiFi card was just a lucky guess. I got the cheapest N 5ghz model I could find and fortunately it worked perfectly. You'll have to let me know how you get on with the twin aerials. I think one is for transmission and one is for reception (but I'm not 100% on this).

Thanks for the great video etc. It's given me the idea to do the same as I could do with 80211.n speeds, I was just wondering if anyone has an idea about what SMA antenna to use as they are usually made for the 2.4Ghz band and not the 5Ghz or does in not matter that much at all... any suggestions on which one would get the most out of the wireless in terms of make/brand within reason cost wise?
Thanks again.

After I made this video, I found out that there were different aerials for 5ghz and 2.4ghz frequencies. As my aerial was a bit floppy I decided to buy a replacement 5ghz equivalent model.

It didn't make a tiny bit of difference to the signal quality or strength received for me, so based on my experience I'd say just get the 2.4ghz aerial.

I ordered 2.4 GHz - 2dbi D-link and 5 dbi Linksys antennas, and I also found a 5GHz - 9dbi model that is only 13 cm long.

You can get any of these on Ebay for less than 5 USD each, shipping included, sent from Hong Kong or China, if you don't mind waiting around 10-15 days. I'm still waiting for mine to arrive.

Hello Techmoan,
Thanks for the proof that the Revo actually has the ability to achieve wireless N speeds with an external antenna. I also replaced the Atheros pci-e card with a ebay'd chinese hp card (HP Intel 4965 (441086-001)) and downloaded the W7x64 Home Premium driver for the 2530p laptop from (card choice was based on my being stateside). My speed jumped from a pitiful 15Kbps to about 3Mbps and I can stream everything but HD flash from the TV networks (eg - wireless properties indicate 5 bars and 130Mbps; cpu is 50-60%, free memory is 1GB w/ 4GB installed. I'm going to follow your lead and see what happens! Kudos.

@ Tom & Freydis,
The R3610 will only support up to 3GB RAM and Acer don't seem to have any plans to update the BIOS for 4GB support, little bit dodgy considering they were selling them with 4GB?! They've stopped now and you can't get a 4GB box off the shelf anymore.

My Revo is actually faster browsing than my desktop. My revo has an upgraded intel 5100 mini pci-e, but just the standard antenna (waiting for my u.fl to sma pigtail to arrive) and my desktop has a 9DBi external antenna - fingers crossed it'll pick up even more with an external. Some flash video was a bit choppy but installing flash 10.1 beta soon sorted that out.

Brilliant video, I was stuck between a ASROCK ION 330-HT and the revo, your video swung it and i'm very happy with the revo. Cheers mate!
