1 00:00:00,240 --> 00:00:06,319 As ubiquitous as secure digital or SD 2 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. 3 00:00:09,040 --> 00:00:16,240 If you bought a digital camera back in the late 1990s or early 2000s, cuz 4 00:00:14,240 --> 00:00:20,160 you're old like me, you probably remember the confusing selection of 5 00:00:18,480 --> 00:00:26,560 memory cards that you had to choose from. Compact flash, smart media, memory 6 00:00:23,680 --> 00:00:31,840 stick. So, how is it then that SD ended up winning the format war? Well, 7 00:00:29,279 --> 00:00:36,239 although SD was originally pushed by several different companies as a 8 00:00:33,680 --> 00:00:42,640 removable storage format that supported DRM for music, hence the name secure 9 00:00:39,680 --> 00:00:48,000 digital. Everyone kind of forgot about that functionality soon after the cards 10 00:00:45,280 --> 00:00:53,039 hit the market and instead took note of their much more convenient size compared 11 00:00:50,719 --> 00:00:57,440 to compact flash and their greater storage potential compared to smart 12 00:00:54,879 --> 00:01:02,640 media. SD also had the advantage of being a more open standard than memory 13 00:01:00,160 --> 00:01:09,360 stick, which today is almost exclusively found on Sony devices, or the XD picture 14 00:01:06,560 --> 00:01:14,080 card, meaning that it became relatively cheap for companies to start including 15 00:01:11,280 --> 00:01:18,640 on their digital cameras, computers, and more portable things like GPS devices. 16 00:01:17,200 --> 00:01:26,960 Even though you could expect to pay about $200 for a 128 megabyte SD card 17 00:01:24,320 --> 00:01:31,680 when they first came out in 2001, prices quickly fell as the format was 18 00:01:29,280 --> 00:01:37,360 introduced into more and more gadgets. So by the mid200s, SD had clearly 19 00:01:35,040 --> 00:01:41,520 started to dominate the market, but the unyielding demand for smaller, higher 20 00:01:39,920 --> 00:01:46,880 capacity storage meant that the technology was still being pushed 21 00:01:43,280 --> 00:01:49,520 forward. 2003 brought us the mini SD 22 00:01:46,880 --> 00:01:56,000 card, followed by the much more widely adopted micro SD card in 2005. So, 23 00:01:53,360 --> 00:02:01,680 thanks to decreases in the size of flash transistors that actually store the data 24 00:01:59,119 --> 00:02:06,719 and an increase in how many can be crammed onto one card, we actually now 25 00:02:04,079 --> 00:02:10,479 have SD cards in capacities that were unthinkable 26 00:02:08,239 --> 00:02:16,000 less than two decades ago. with both standardsized and micro SD cards now 27 00:02:13,360 --> 00:02:20,080 available that can hold over half a terabyte. Meaning that the highest 28 00:02:18,000 --> 00:02:26,480 capacity micro SD card on the market right now can hold over 35,000 29 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 30 00:02:29,920 --> 00:02:37,040 smaller physically. Unfortunately though, these much higher capacities 31 00:02:34,480 --> 00:02:42,000 mean that not all SD cards will function properly in any slot that will 32 00:02:39,519 --> 00:02:48,959 physically fit them. The original SD spec only supported up to 2 GB, while 33 00:02:45,360 --> 00:02:52,080 SDHC cards can hold up to 32 gigs, and 34 00:02:48,959 --> 00:02:54,480 the newer SDXC can handle up to 2 35 00:02:52,080 --> 00:03:00,319 terabytes. Although cards that spacious aren't on the market yet, unlike 36 00:02:57,120 --> 00:03:02,879 standards like USB or SATA, SD cards 37 00:03:00,319 --> 00:03:08,800 aren't backwards compatible with older readers that only support an older spec. 38 00:03:05,599 --> 00:03:11,360 So SDXC cards won't work in that card 39 00:03:08,800 --> 00:03:15,440 reader from 2007. This matter made worse by the fact that it requires XFAT, a 40 00:03:13,840 --> 00:03:19,920 newer file system that some older versions of Windows don't support 41 00:03:17,440 --> 00:03:25,599 natively. Newer readers, though, are usually fine with older cards. So, aside 42 00:03:23,040 --> 00:03:30,319 from standard SD versus the higher capacity versions, you also need to pay 43 00:03:27,920 --> 00:03:37,200 attention though to the speed rating. Lower-end models might have a number 2 4 44 00:03:33,760 --> 00:03:39,920 6 inside a circle giving you an idea of 45 00:03:37,200 --> 00:03:46,640 the maximum right speed in megabytes per second. While higher-end cards are often 46 00:03:42,400 --> 00:03:49,440 classified as UHS1 or UHS2, indicating 47 00:03:46,640 --> 00:03:54,799 both higher bus speeds and right speeds, with UHS2 cards offering right speeds of 48 00:03:51,920 --> 00:03:58,319 at least 30 megabytes per second, which is important if you're trying to do 49 00:03:56,239 --> 00:04:04,080 something demanding like record 4K video, as the card needs to be able to 50 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 51 00:04:05,920 --> 00:04:12,319 for when shopping for flash memory, at least the days when there were six or 52 00:04:10,000 --> 00:04:17,759 seven different completely different physical formats vying for your 53 00:04:14,319 --> 00:04:20,720 attention are over. Just try not to drop 54 00:04:17,759 --> 00:04:24,919 your micro SD card between your uh couch cushions, if you know what I mean. 55 00:04:24,960 --> 00:04:30,800 Was that a getting something stuck in your butt joke? 56 00:04:28,080 --> 00:04:34,639 What?
