1 00:00:00,110 --> 00:00:06,560 Flash memory cards like flash drives, flash memory cards or memory cards as they are fondly referred 2 00:00:06,560 --> 00:00:07,070 to. 3 00:00:07,640 --> 00:00:14,810 Also use Nand flash memory, which, as we previously learned, is a non-volatile solid state memory. 4 00:00:15,200 --> 00:00:21,830 Unlike USB flash drives, however, these cards do not come with a USB interface and must be used with 5 00:00:21,830 --> 00:00:24,320 either an adapter or memory card reader. 6 00:00:24,890 --> 00:00:31,370 Over the years and decades, we've had several formats of memory cards graced our desktops, laptops, 7 00:00:31,370 --> 00:00:37,310 mobiles and other devices, including cameras, MP3 players and even toys. 8 00:00:37,460 --> 00:00:42,920 Although I'll only cover some of the more popular cards used today, it is important that you are at 9 00:00:42,920 --> 00:00:46,910 least familiar with memory cards and are also able to identify them. 10 00:00:47,450 --> 00:00:51,260 The flash memory card types we will look at are as follows. 11 00:00:51,590 --> 00:00:57,410 Memory Stick Pro Duo Mspd Proprietary Card developed by Sony. 12 00:00:57,440 --> 00:00:58,850 Secure Digital. 13 00:00:58,850 --> 00:01:03,390 SD Secure Digital High Capacity Sdhc two. 14 00:01:03,480 --> 00:01:05,430 232 GB capacity. 15 00:01:05,460 --> 00:01:16,410 Many Sdhc Microsdhc Secure digital extended capacity Sdhc 32GB two TB capacity. 16 00:01:16,500 --> 00:01:20,620 Compact flash cf Multimediacard. 17 00:01:20,670 --> 00:01:21,200 Emmc. 18 00:01:22,290 --> 00:01:23,940 Xd-picture XD. 19 00:01:24,240 --> 00:01:25,410 Smartmedia. 20 00:01:25,590 --> 00:01:28,530 Some of the aforementioned card types. 21 00:01:28,530 --> 00:01:31,980 I've opted to show three from my collection in the following photo. 22 00:01:32,010 --> 00:01:35,430 The card to the left is a Sony memory Stick pro duo. 23 00:01:35,460 --> 00:01:41,490 The card in the middle is an SD card that has a sliding lock to the side used to prevent data from being 24 00:01:41,490 --> 00:01:42,300 overwritten. 25 00:01:42,300 --> 00:01:46,500 And the card to the right is the more common card of today, the micro SD. 26 00:01:46,800 --> 00:01:52,260 I'd like to do a brief comparison of these three cards developed at least a decade apart. 27 00:01:52,290 --> 00:01:59,220 The older Du card is larger with a capacity of two gigabytes, although not seen on the SD card. 28 00:01:59,250 --> 00:02:03,930 Its capacity is four gigabytes and the smallest and newest car to the right. 29 00:02:03,960 --> 00:02:09,330 Micro SD actually has a whopping 64GB of storage capacity. 30 00:02:09,780 --> 00:02:14,010 Have a look at the following photo to see a close up of the micro SD card. 31 00:02:14,040 --> 00:02:22,530 It shows the capacity of 64GB and also the class of the micro SD card class, 1060 four gigabytes of 32 00:02:22,530 --> 00:02:25,260 data on something as small as a fingernail. 33 00:02:25,380 --> 00:02:34,620 Still, micro SD cards are being developed with even larger capacities of 128GB and even 256GB. 34 00:02:34,650 --> 00:02:41,490 The various classes of micro SD cards identify their reads, slash write speeds and suggested uses. 35 00:02:41,700 --> 00:02:45,900 I do suggest getting a class ten C ten micro SD card. 36 00:02:45,900 --> 00:02:53,280 If purchasing one as the C ten is much faster than the other classes two, four and six and supports 37 00:02:53,280 --> 00:02:56,640 constant HD and even 4K video recording. 38 00:02:56,700 --> 00:03:05,100 Classes two, four, six and ten support speeds of up to two MEPs, four MEPs, six MEPs and ten MEPs 39 00:03:05,100 --> 00:03:08,610 respectively, and are known as SD Speed Class. 40 00:03:08,820 --> 00:03:16,410 Class one and Class three are known as the HS speed class and support speeds of up to ten MEPs and 30 41 00:03:16,410 --> 00:03:17,790 maps respectively. 42 00:03:17,820 --> 00:03:25,080 The newer video speed class, which is recommended for HD video in 4K and 8-K, supports much faster 43 00:03:25,080 --> 00:03:25,860 speeds. 44 00:03:25,890 --> 00:03:36,570 The v ten v 30 v 60 and v 90 cards support speeds of up to ten minutes, 30 maps, 60 Mbps and 90 MEPs 45 00:03:36,570 --> 00:03:37,680 respectively. 46 00:03:38,100 --> 00:03:45,030 As mentioned earlier, flash memory cards require card readers which connect to laptops, desktops and 47 00:03:45,030 --> 00:03:47,670 other media players using USB ports. 48 00:03:47,700 --> 00:03:53,960 The following photo shows one of my many card readers which supports compact flash memory Stick, pro 49 00:03:53,960 --> 00:03:58,080 duo, Secure Digital and even the Smartmedia cards. 50 00:03:58,440 --> 00:04:04,770 I'd suggest getting yourself a few USB card readers that support the various card types to easily access 51 00:04:04,770 --> 00:04:08,060 cards, whether for ordinary use or data recovery. 52 00:04:08,070 --> 00:04:16,110 As most newer laptops, desktops and devices may only support SD card slots and USB interfaces here.
