What does Write Speed mean?

Write speeds are generally the most important feature of a memory card. Write speeds determine the amount of time it takes to transfer the data, the moment you for example, click the button on your camera to ask the camera to take the image. You will probably remember that back in the early days of SD memory cards, there was an awful amount of lag time on cards, i.e from when you heard the click on the button (when you asked your camera to take the picture), to when you heard the double click (which is normally when the image has been written to the card).

What does Read Speed Mean?

Read speeds indicate the amount of time it takes for a card to transfer the data to a PC/Laptop. I.e the amount of time it takes to read the data off the card. Generally the higher the capacity of the card, this will naturally give a higher write speed. So a 4GB card will offer lower read speeds than a 32GB memory card. Read speeds are particularly important on higher capacity cards as if you have a 32GB full up with data and the read speed is poor/low then you will wait much longer to transfer the data from the card. A Pretec P240 USB 3.0 Memory Card Reader Writer will drastically reduce wait times for transferring data. Up to 5Gb/s! Thats up to 10x faster than the traditIonal USB 2.0!

If I see 45MB/s What Does This Mean?

If buyers are particular about what they need in respect of fast read or fast write speeds then you need to make sure that you are aware of this number quoted on the card. More often than not, this will be the read speed quoted, and not the write speed. This is a bit cheeky of the manufacturers really, as most specific users that look into this figure, require high value write speeds, and instantly you assume the number quoted on the card is the write speed, but it is infact usually the read speed, as the read speed is always a higher number than the write speed.

What impact do Write Speeds have on HD devices?

Generally a class 10 card and above is recommended for HD movies/video capture. Again this boils down to the write speed, and the amount of time it takes to write the data to the card. There will be a more seamless writing efficiency, with a class 10 card for HD video. i.e no interuptions in the recording smoothness. You may find your device will encounter issues with anything below a Class 6 SDHC memory card.

If I See Something Like 133x, What Does This Mean?

This is just another way of showing a read or write speed. Below is a list of how to convert a figure with an ‘x’ on the end into the more industry standard MB/s.

8X = 1.2 Mb/sec
12X = 1.8 Mb/sec
20X = 3.0 Mb/sec
25X = 3.8 Mb/sec
30X = 4.5 Mb/sec
40X = 6.0 Mb/sec
60X = 9.0 Mb/sec
66X = 10.0 Mb/sec
80X = 12.0 Mb/sec
90X = 15.0 Mb/sec
133X = 20.0 Mb/sec

What Memory Card Is Suitable For My Device?

This really depends on two things, your budget, although flash memory is very affordable now, and what you need your memory card for.

If you simply require your memory card for a simple compact point and shoot digital camera, then anything around the Class 4 product range will be perfect. E.g the Kingston Class 4 SDHC Memory Card.

If you have a compact digital camera that will shoot HD video, then any brand of memory card that’s class 10 rated will be more than suitable.

If you have a more precise camera such as a digital SLR camera then something along the lines of the new UHS SDHC memory cards would probably be more suitable for your needs.

Transcend Class 10 SDHC Memory Cards are ideal for today’s HD devices that require fast write speeds in order to capture the HD video in all its glory.

So here we have the Transcend 4GB Class 10 SDHC Memory Card which we tested using the H2testw software to verify, as near as available to the average punter, the read and write speeds.

The 4GB Class 10 cards came out with impressive results;
Read Speed: 18.4MB/s
Write Speed: 9.67MB/s

You will no doubt see from the above that the 4GB does’nt quite write at over 10MB/s. However we must add that host devices, conditions etc do have an effect on read and write speeds, so we wont worry about this slight discrepancy on our test results.

The most important data as always is the write speed, which is the speed at which is takes to write the data to the memory card. So in easy language if you’re not tech minded, from when you click the button on your device e.g digital camera, the time it takes to issue the image you have just taken, to the memory of the card. So in theory with fast write speeds, then you should be able to take more images and frames per second.

A HD video device, e.g camcorder or camera is slightly more specific on what card is required. You ideally will need a class 6 memory card or above to shoot in HD, this is to prevent breakup of the video when recording, and to improve the smoothness of the video as video flows rather than an image, which is captured as a still.

Read speeds are critical for time that it takes for data to be copied to your PC or Laptop for example. So if you have a 32GB memory card full of data, then a higher read speed will take less time to transfer that data to your PC/Laptop. It is actually quite noticeable when it comes to read speeds, especially on the 32GB cards, as a card full of data can take quite a while to read/transfer the data. So if you’re not into waiting around for long transfer times then we recommend the faster read speeds! Generally, the higher the write speed and capacity of a card, is reflected in the read speeds.  E.g a 32GB card class 10 will have a higher write speed over a 4GB class 10 SDHC memory card.

These Transcend cards are rated at 10MB/s but as you can see from the above they’re well over the minimum sustained write speed. The test results screenshot is shown below.

We often imagined that the memory card read and write speeds that were claimed by manufacturers, would be similar to the claimed 0-62mph sprints of cars. By this we mean unachievable. However, how very pleasantly surprised after doing our own tests on the read and write speeds of the Transcend SDHC Memory Cards in this particular instance.

Transcend Class 10 SDHC Memory Cards are ideal for today’s HD devices that require fast write speeds in order to capture the HD video in all its glory.

Speed, Speed and more Speed. This is what heavy users of modern technology products that accept memory cards require today. Less waiting time to transfer files. Less waiting times to write files to cards. Well Transcend have come along and helped out with this by releasing their range of class 10 MicroSDHC (MicroSD) Memory Cards.

Class 10 cards are recommended for HD recording. This is a bit of a myth really that class 10 cards are required. Its not the memory card that dictates the HD video, its your device. So technically a Class 2 card would be OK for HD video, although we’d recommend something above a class 4. Its probably the motion/movement that would suffer on lower class rated cards. I.e the time it takes to write the data to the card from your device, hence why class 10 are recommended, as less time to wait, 10MB/s transfer rate (as this card will give) will write data to the card from your device at 10MB/s, as opposed to a class 2 which would write data to the card at 2MB/s.
