My Sony says to to use memory cards that are at least class 4. Over at Biglots, they have PNY sdhc 16g cards Class 4 for only $10 each, a weekend sale.
In the past I used Transcend class 10 memory mainly because they were cheap, but these PNY chips look pretty tempting for my vacation.

If it's a camcorder and says you only need a class 4 card, there is no advantage for class 10. You won't get better video. Class 4 is actually the minimum speed the card provides; will do at least that advertised speed or higher.

If it were a DSLR, then it might matter for burst photos or if you had a hacked camera with option for high video bit rates.

An advantage of getting good cards now is they are more future-proof for devices you may eventually own that may require better cards. Transfer from card to pc transfer time may help with a faster card, but not the video quality or performance if only class 4 is required.

I like fast cards when uploading my videos using my USB 3.0 card reader using the USB 3.0 port on my PC. My last card purchase was March 15 for a pair of Sony 16GB SDHC cards for $18.95 ($9.45 each ) with free shipping from B&H with ratings of :
•Class 10 Speed
•Max. Read Speed: 94MB/s
•Max. Write Speed: 45MB/s
•Ultra High Speed Class 1

That was a very good price. It that sale comes again, we should all buy some. Unfortunately, that sale was short term. I tried and missed it!

But without such a sale, the OP has a chance to buy Class 4 for the same price.

He may not have USB 3.0 card reader. So, how many real minutes a day does it save to have the Class 1 cards?

Speed is fun, but it may not always be worth the dollars.

My SD600 would take whatever I would give her.
1920x1080 60p.

Not one bad clip.

I don't see any advantages of using class 10 on the modern cams.

Good time to buy computers and computer parts: NEVER

So $8 with free shipping is too much for a Class 10 16GB SDHC card ? I don't care if my cameras would work with a Class 1 card, I just prefer fast uploads of my videos than slow uploads.

I use and recommend the SanDisk 64GB SDXC Memory Card Extreme Pro Class 10 UHS-I http://www.bhphotovideo.com/c/product/824149-REG/SanDisk_SDSDXPA_064G_A75_Extreme_Pro_64GB_SDHC_SDXC.html

Max. Read Speed: 95MB/s (claimed)
Max. Write Speed: 90MB/s (claimed)

5GB Blackmagic file R/W test (limited by my Clevo laptop's card reader) 76MB/s read, 72MB/s write.

Do buy only the fastest cards for a whole bunch of reasons.

eg, after a days shooting on holidays, I may return to my hotel room @ 5:00pm, and immediately back up both my cameras 64GB cards to my laptop's SSD. Typically I might be backing up 15 - 30GB per day. Q - just how long do you want to wait ? A slow card will take a loooong time to do this. Once on the laptop, I may quickly delete the obvious rubbish (unusable footy), then copy what is left from the lappy to a portable USB3 HDD. Then reformat the camera SD cards.

ALLWAYS have your shots in 2 places ! I don't trust the laptop or the HDD !

Whilst the lappy to HDD backup is going, I have a shower, get ready for dinner of the evening's other activities.

After an evening's shooting, I will backup my cameras' cards to the lappy, or if to 'tired' do it in the morning before breakfast.

So, obviously using the fastest SD cards is a big help in the real world of travel.

5GB Blackmagic file R/W test (limited by my Clevo laptop's card reader) 76MB/s read, 72MB/s write.

In my 60D:
Previous Sandisk card has 45MB/s read, 41MB/s write. This allowed a burst of 8x continuous shots @ 5.3 shots per second, then 1 shot per second thereafter capturing RAW+JPG each shot, ie 33MB per shot. (will also allow 50x shots continuous JPG only).

But, this new 90MB/s Write card has transformed my 18Mpix CANON 60D camera. Allows 8x RAW+JPG shot initial burst, then a just perceivable pause (eg 0.25sec), then another 6x RAW+JPG shot burst before slowing down. Effectively 14x RAW+JPG shot continuous bust now = 460MB captured to the camera's buffer just in 3.5 seconds ! This is a huge improvement. And the camera is ready for another shorter burst after another second pause. I had found the 8x shot burst limiting for kids sports.

18Mpix RAW only – now is 15x shot continuous burst (no pause) before slowing down.

VIDEO: The change here is the recovery time when banging of still shots during video. The cycle time is much shorter and little of the video is lost now (was typically 1sec of video lost – intrusive for sports).

From 8x shot burst (also CANON's specs) to 15x shot burst.

Best camera upgrade ever
