OCZ SSD is the worst SSD!

ocz_ssdOK, let me share this to the world how bad this OCZ SSD. Bought 3 OCZ SSD months ago. First SSD is where my OS installed, Windows 7 Professional. 2nd SSD is my MySQL Database, 3rd SSD is my Development Source Codes. OS SSD crashed first after 6 months and undetectable. Then the vendor replaced the SSD with Samsung and works fine until now. Next is the DB SSD crashed after 9 months. Dev SSD crashed after 12 months. How can you rely on these OCZ SSDs? I lost tons of files because of these SSDs. If you want SSD, buy Intel SSD or Samsung SSD and they are the reliable brands. Never again be fooled with those other SSDs. Too much promising yet they are all crap! Advise: NEVER BUY OCZ SSD! FULL OF CRAP!
Linux: Serial Port Communication
Posted: 25 Nov 2014, 6:18am - Tuesday
Since HyperTerminal was removed in Windows 7, I decided to look up on Linux tools for serial port communication and found minicom command. Here's how to install & use it (in my case I used Linux Mint):
# apt-get install minicom
Then after installation, cast a command:
# minicom -s

            | Filenames and paths      |
            | File transfer protocols  |
            | Serial port setup        |
            | Modem and dialing        |
            | Screen and keyboard      |
            | Save setup as dfl        |
            | Save setup as..          |
            | Exit                     |
            | Exit from Minicom        |
Then you have to setup the serial port,
    | A -    Serial Device      : /dev/ttyUSB0                              |
    | B - Lockfile Location     : /var/lock                                 |
    | C -   Callin Program      :                                           |
    | D -  Callout Program      :                                           |
    | E -    Bps/Par/Bits       : 9600 8N1                                  |
    | F - Hardware Flow Control : Yes                                       |
    | G - Software Flow Control : No                                        |
    |                                                                       |
    |    Change which setting?                                              |
So in my case, I used USB to Serial connector, so I set Serial Device to ttyUSB0 After that, go to Exit and you'll be connected to the device you want to connect like Cisco routers/switch.

[gallery] When my friend's Card Reader goes something wrong, I tried to fix it and found that the wires are pulled out. So I found the solution (shown below) to resold the wires back into its position.
Pin one side Signal Description Pin other side
1 USB Vcc (Vbus) usually RED, wire should be 20-28 AWG 1
2 USB Data - usually WHITE, wire should be 28 AWG 2
3 USB Data + usually GREEN, wire should be 28 AWG 3
4 GND usually BLACK, wire should be 20-28 AWG 4
