0:00:19.160 --> 0:00:30.320
<v Speaker 1>stuff works dot com where smart happens. Hi. I'm Marshall

0:00:30.320 --> 0:00:33.400
<v Speaker 1>Brain with today's question, what are the fastest hard disk

0:00:33.520 --> 0:00:37.479
<v Speaker 1>drives available today? If you look back through the recent

0:00:37.600 --> 0:00:40.479
<v Speaker 1>history of personal computers, you can see that there's been

0:00:40.520 --> 0:00:45.000
<v Speaker 1>a trend toward faster and faster hard disc drives and connections.

0:00:45.560 --> 0:00:49.400
<v Speaker 1>Several years ago, the standard was a spinning mechanical hard

0:00:49.440 --> 0:00:53.199
<v Speaker 1>disk drive connected to a parallel A T A connector.

0:00:53.840 --> 0:00:57.480
<v Speaker 1>Then the industry transition to a serial A T A connector,

0:00:57.880 --> 0:01:00.920
<v Speaker 1>first at one point five gigabits per second, then at

0:01:00.960 --> 0:01:04.440
<v Speaker 1>three gigabits per second, and now it's six gigabits per second.

0:01:05.560 --> 0:01:08.080
<v Speaker 1>No mechanical hard disc can really keep up with a

0:01:08.160 --> 0:01:11.200
<v Speaker 1>six gigabit per second connection. The reason they put that

0:01:11.240 --> 0:01:15.040
<v Speaker 1>in place is because of solid state drives. These drives

0:01:15.120 --> 0:01:17.760
<v Speaker 1>can actually pump data fast enough to make use of

0:01:17.760 --> 0:01:21.480
<v Speaker 1>that connection. So that's the latest high speed standard. But

0:01:21.560 --> 0:01:25.080
<v Speaker 1>people always want to go faster, so now they're taking

0:01:25.200 --> 0:01:29.520
<v Speaker 1>solid state drives, putting them on cards, connecting them straight

0:01:29.520 --> 0:01:34.080
<v Speaker 1>into the motherboard using the pc I express connection. Right now,

0:01:34.160 --> 0:01:37.920
<v Speaker 1>that offers a speed of about one gigabyte per second,

0:01:38.360 --> 0:01:40.039
<v Speaker 1>and it could go all the way up to about

0:01:40.040 --> 0:01:43.679
<v Speaker 1>eight gigabytes per second with the current pc I Express design.

0:01:44.200 --> 0:01:48.080
<v Speaker 1>These drives are described by one magazine as brain melting

0:01:48.200 --> 0:01:51.400
<v Speaker 1>lea fast. They can transfer a one gigabyte file and

0:01:51.480 --> 0:01:55.200
<v Speaker 1>about one second. Right now, these super fast drives are

0:01:55.200 --> 0:01:58.360
<v Speaker 1>fairly expensive, about fifty cents a gigabyte compared to a

0:01:58.440 --> 0:02:01.320
<v Speaker 1>dime per gigabyte for a norm most spinning hard disc.

0:02:01.720 --> 0:02:05.280
<v Speaker 1>But even these aren't the fastest hard discs available. If

0:02:05.280 --> 0:02:08.919
<v Speaker 1>you want to be the fastest, you would take dynamic RAM,

0:02:09.120 --> 0:02:11.520
<v Speaker 1>put it on a board, and plug that into the

0:02:11.520 --> 0:02:16.320
<v Speaker 1>pc I Express slot. Dynamic RAM has some disadvantages. It's

0:02:16.320 --> 0:02:19.560
<v Speaker 1>pretty big, relatively speaking, and you have to keep power

0:02:19.560 --> 0:02:21.920
<v Speaker 1>to it constantly, which means you need a big battery

0:02:21.960 --> 0:02:23.799
<v Speaker 1>to back it up in case the power goes out

0:02:23.880 --> 0:02:26.680
<v Speaker 1>or somebody turns off the machine. And it's also pretty

0:02:26.680 --> 0:02:30.600
<v Speaker 1>expensive about twenty dollars per gigabyte or so. However, it

0:02:30.800 --> 0:02:34.960
<v Speaker 1>is shockingly fast, much faster than flash memory. You could,

0:02:35.160 --> 0:02:37.720
<v Speaker 1>in theory, think of it as using up the entire

0:02:38.120 --> 0:02:42.480
<v Speaker 1>PC I Express bandwidth. For more on this and thousands
