WEBVTT 00:00:00.240 --> 00:00:06.319 As ubiquitous as secure digital or SD 00:00:03.520 --> 00:00:10.880 cards are these days, it wasn't too long ago that they weren't king of the hill. 00:00:09.040 --> 00:00:16.240 If you bought a digital camera back in the late 1990s or early 2000s, cuz 00:00:14.240 --> 00:00:20.160 you're old like me, you probably remember the confusing selection of 00:00:18.480 --> 00:00:26.560 memory cards that you had to choose from. Compact flash, smart media, memory 00:00:23.680 --> 00:00:31.840 stick. So, how is it then that SD ended up winning the format war? Well, 00:00:29.279 --> 00:00:36.239 although SD was originally pushed by several different companies as a 00:00:33.680 --> 00:00:42.640 removable storage format that supported DRM for music, hence the name secure 00:00:39.680 --> 00:00:48.000 digital. Everyone kind of forgot about that functionality soon after the cards 00:00:45.280 --> 00:00:53.039 hit the market and instead took note of their much more convenient size compared 00:00:50.719 --> 00:00:57.440 to compact flash and their greater storage potential compared to smart 00:00:54.879 --> 00:01:02.640 media. SD also had the advantage of being a more open standard than memory 00:01:00.160 --> 00:01:09.360 stick, which today is almost exclusively found on Sony devices, or the XD picture 00:01:06.560 --> 00:01:14.080 card, meaning that it became relatively cheap for companies to start including 00:01:11.280 --> 00:01:18.640 on their digital cameras, computers, and more portable things like GPS devices. 00:01:17.200 --> 00:01:26.960 Even though you could expect to pay about $200 for a 128 megabyte SD card 00:01:24.320 --> 00:01:31.680 when they first came out in 2001, prices quickly fell as the format was 00:01:29.280 --> 00:01:37.360 introduced into more and more gadgets. So by the mid200s, SD had clearly 00:01:35.040 --> 00:01:41.520 started to dominate the market, but the unyielding demand for smaller, higher 00:01:39.920 --> 00:01:46.880 capacity storage meant that the technology was still being pushed 00:01:43.280 --> 00:01:49.520 forward. 2003 brought us the mini SD 00:01:46.880 --> 00:01:56.000 card, followed by the much more widely adopted micro SD card in 2005. So, 00:01:53.360 --> 00:02:01.680 thanks to decreases in the size of flash transistors that actually store the data 00:01:59.119 --> 00:02:06.719 and an increase in how many can be crammed onto one card, we actually now 00:02:04.079 --> 00:02:10.479 have SD cards in capacities that were unthinkable 00:02:08.239 --> 00:02:16.000 less than two decades ago. with both standardsized and micro SD cards now 00:02:13.360 --> 00:02:20.080 available that can hold over half a terabyte. Meaning that the highest 00:02:18.000 --> 00:02:26.480 capacity micro SD card on the market right now can hold over 35,000 00:02:23.920 --> 00:02:32.560 times as much data as a standard 3 and 1/2 in floppy while being over 50 times 00:02:29.920 --> 00:02:37.040 smaller physically. Unfortunately though, these much higher capacities 00:02:34.480 --> 00:02:42.000 mean that not all SD cards will function properly in any slot that will 00:02:39.519 --> 00:02:48.959 physically fit them. The original SD spec only supported up to 2 GB, while 00:02:45.360 --> 00:02:52.080 SDHC cards can hold up to 32 gigs, and 00:02:48.959 --> 00:02:54.480 the newer SDXC can handle up to 2 00:02:52.080 --> 00:03:00.319 terabytes. Although cards that spacious aren't on the market yet, unlike 00:02:57.120 --> 00:03:02.879 standards like USB or SATA, SD cards 00:03:00.319 --> 00:03:08.800 aren't backwards compatible with older readers that only support an older spec. 00:03:05.599 --> 00:03:11.360 So SDXC cards won't work in that card 00:03:08.800 --> 00:03:15.440 reader from 2007. This matter made worse by the fact that it requires XFAT, a 00:03:13.840 --> 00:03:19.920 newer file system that some older versions of Windows don't support 00:03:17.440 --> 00:03:25.599 natively. Newer readers, though, are usually fine with older cards. So, aside 00:03:23.040 --> 00:03:30.319 from standard SD versus the higher capacity versions, you also need to pay 00:03:27.920 --> 00:03:37.200 attention though to the speed rating. Lower-end models might have a number 2 4 00:03:33.760 --> 00:03:39.920 6 inside a circle giving you an idea of 00:03:37.200 --> 00:03:46.640 the maximum right speed in megabytes per second. While higher-end cards are often 00:03:42.400 --> 00:03:49.440 classified as UHS1 or UHS2, indicating 00:03:46.640 --> 00:03:54.799 both higher bus speeds and right speeds, with UHS2 cards offering right speeds of 00:03:51.920 --> 00:03:58.319 at least 30 megabytes per second, which is important if you're trying to do 00:03:56.239 --> 00:04:04.080 something demanding like record 4K video, as the card needs to be able to 00:04:01.120 --> 00:04:08.080 support the high data rates to keep up. So, while there's still a lot to look 00:04:05.920 --> 00:04:12.319 for when shopping for flash memory, at least the days when there were six or 00:04:10.000 --> 00:04:17.759 seven different completely different physical formats vying for your 00:04:14.319 --> 00:04:20.720 attention are over. Just try not to drop 00:04:17.759 --> 00:04:24.919 your micro SD card between your uh couch cushions, if you know what I mean. 00:04:24.960 --> 00:04:30.800 Was that a getting something stuck in your butt joke? 00:04:28.080 --> 00:04:34.639 What?
