1
00:00:00,640 --> 00:00:07,240
this is going to be a relatively quick unboxing this is the Seagate momentus XT

2
00:00:05,200 --> 00:00:11,679
and it is an unbagging rather more than an unboxing this is a 320 GB version of

3
00:00:10,200 --> 00:00:17,240
the drive but it's available in a few different capacities and this is a

4
00:00:14,400 --> 00:00:23,080
revolutionary device the reason is because and you can see that when I open

5
00:00:19,520 --> 00:00:25,920
it up it will come out of the bag and it

6
00:00:23,080 --> 00:00:30,920
will be 2 and2 inches and it will have a SATA interface or SATA 2 rather power

7
00:00:28,720 --> 00:00:34,079
and data and then jump but so far I haven't shown you anything

8
00:00:32,480 --> 00:00:38,239
revolutionary about it what's revolutionary about this is actually

9
00:00:35,600 --> 00:00:42,520
what's under the hood this is a magnetic drive that's why you get a nice high

10
00:00:40,039 --> 00:00:49,280
capacity at a very reasonable price but it also has a small 4 gig SSD built in

11
00:00:47,399 --> 00:00:54,359
now that doesn't mean that you actually get uh any significant capacity boost

12
00:00:52,600 --> 00:01:00,239
you're not adding the SSD for that you're adding the SSD built in in order

13
00:00:57,239 --> 00:01:03,359
to get a speed boost so while you won't

14
00:01:00,239 --> 00:01:05,360
quite get the speed of an SSD you won't

15
00:01:03,359 --> 00:01:09,280
be stuck with the speed of a hard drive now I'm also going to explain a little

16
00:01:07,000 --> 00:01:14,080
bit how all this works we've had cash on hard drives for a very very long time

17
00:01:11,880 --> 00:01:19,119
cash acts as a way for the hard drive to take frequently accessed data and throw

18
00:01:16,640 --> 00:01:23,840
it onto a much faster storage medium so that for for like a quick random read or

19
00:01:21,720 --> 00:01:28,560
a quick random write you can use the cash for much faster performance than if

20
00:01:26,400 --> 00:01:34,439
you actually had to wait for the disc to rotate for the ARM to seek and for it to

21
00:01:31,000 --> 00:01:37,600
find that bit of data now what an SSD

22
00:01:34,439 --> 00:01:39,399
allows us to do is have a much larger

23
00:01:37,600 --> 00:01:44,159
cach typically even on a high-end desktop Drive these days you're going to

24
00:01:41,280 --> 00:01:50,640
see only about a 32 Meg to a 64 Meg cache so when we start introducing a 4

25
00:01:46,960 --> 00:01:53,479
Gigabyte SSD cache that well it's not as

26
00:01:50,640 --> 00:01:58,399
fast as normal cache but it is much bigger and it does give much much better

27
00:01:56,439 --> 00:02:03,159
performance for small random reads and writes versus me magnetic okay so

28
00:02:01,240 --> 00:02:07,920
basically what cate's aiming to do with this is take some of the very frequently

29
00:02:05,320 --> 00:02:12,000
used data things like your OS so you can reduce things like boot time as well as

30
00:02:09,920 --> 00:02:16,280
very frequently Asked uh accessed programs and you can speed up the

31
00:02:14,280 --> 00:02:21,680
performance of this drive and then you can also just have regular performance

32
00:02:18,280 --> 00:02:24,480
when you load on your main programs and

33
00:02:21,680 --> 00:02:27,840
any sort of large data storage files so what they're doing on a micro scale is

34
00:02:26,519 --> 00:02:31,599
what a lot of people have been doing for a while is they're taking a small SSD

35
00:02:30,120 --> 00:02:36,239
and using it as their boot drive for their boot Drive in their critical applications and then they're installing

36
00:02:34,640 --> 00:02:42,959
a separate magnetic hard drive in their system for mass storage well now it's

37
00:02:38,360 --> 00:02:42,959
all in one unit very cool
