00:00.080 --> 00:03.530
Solid state drives as briefly mentioned before.

00:03.770 --> 00:10.730
SSDs are non-volatile storage media and use Nand flash memory in an array to hold data.

00:11.300 --> 00:13.910
SSDs have been around for quite some time.

00:14.150 --> 00:19.220
However, mainstream use would have been greatly hampered by the high cost of the drive.

00:19.340 --> 00:31.670
Samsung first released a 32GB SSD with a Pata interface in 1996, followed by Sandisk's 32GB SSD but

00:31.670 --> 00:33.650
with its Sata interface.

00:33.860 --> 00:40.430
Although SSD drives use flash memory, the materials used are more high end than that found in flash

00:40.430 --> 00:46.340
drives, which makes it the much preferred option for use as a hard drive but again contributes to the

00:46.340 --> 00:47.420
very high cost.

00:47.450 --> 00:52.760
Some advantages of SSDs come from the fact that there are no moving parts in an SSD.

00:53.360 --> 01:00.450
No moving parts make the SSD more durable in the event of a fall or swift foot to the PC tower as there

01:00.450 --> 01:04.230
are no platters or actuator arms to be scratched or struck.

01:04.350 --> 01:10.620
Also, the faster reads slash write speeds and access times greatly reduce the time taken for the device

01:10.620 --> 01:16.620
to boot or start, and even gives an enhanced experience when using resource intensive software and

01:16.620 --> 01:17.250
games.

01:17.280 --> 01:23.880
As far as digital forensics goes, SSDs are still a relatively new technology that will be constantly

01:23.880 --> 01:26.130
improved upon for some time to come.

01:26.190 --> 01:31.890
It's important to remember that you are not dealing with a mechanical drive and that data on an SSD,

01:32.070 --> 01:38.280
much like a flash drive or memory card, can be lost or wiped within minutes or even seconds.

01:38.400 --> 01:45.270
Although traditional tools can be used to image and recover data from SSDs, I strongly suggest researching

01:45.270 --> 01:52.020
any SSD drive before performing any forensic activities to get a better understanding of its workings

01:52.020 --> 01:56.070
and complexities such as chipping and wear leveling algorithms.

01:56.100 --> 02:02.970
Take note of the pin layout interface for the SSD Connector left side, which connects to a PCI interface

02:02.970 --> 02:06.780
on the board instead of the usual Sata connectors.

02:06.990 --> 02:15.000
The connector in the preceding photo is an M2 non-volatile memory express Nvme SSD connector type.

02:15.000 --> 02:16.950
But there are other types as well.

02:17.070 --> 02:23.880
When performing forensic acquisitions on SSDs, which may require the use of a USB adapter, be sure

02:23.880 --> 02:26.190
you know which connector you are working with.

02:26.220 --> 02:29.520
Different SSD interface types include the following.

02:30.000 --> 02:34.410
Sata 3.0 up to six GB s bandwidth.

02:35.160 --> 02:40.410
Msata up to six GB slashes bandwidth found in older computers.

02:40.650 --> 02:45.450
M2 Sata up to 32 GB slashes bandwidth.

02:46.290 --> 02:48.870
M2 Nvme up to 32.

02:48.900 --> 02:56.190
GB slashes Bandwidth U2 up to 32 GB slashes bandwidth but not very common.
