 SSD is Stand for Solid State Drive . Solid State Drive have improve lot in past few year . SATA ,NVMe , M.2 based SSDs are the most popular ones available now . 

The two primary interfaces that SSDs are available 

1. SATA 

2. PCI Express (PCIe)

SATA vs PCIe

Serial ATA is a computer bus interface that connect host bus adapters to mass storage device such as hard disk drive  , optical drive, and solid state drive . Serial ATA succeeded the earlier Parallel ATA (PATA)

                                                                SATA                                                   PCIe

 
Bandwidth Medium High
Queue Command Depth 32 65536

Advantages

 Half duplex data transfer, in-expesive, low power  comsumption  Super fast speed, faster then SATA, latency reduction 
Disadvantages Low transfer speed, 1m cable length  Limited capacities , expensive , ATA commands
Cost $ $$$
Ideal For  PC, desktop, tablets & datacentres Video editing, financial modelling, high end gaming

How to install a Graphics Card (GPU)

Hello Friends,                                Today i'll tell you how to install a Graphics Card in your gaming PC setup. Installing a GPU can make a world or difference when it comes to gaming on a PC 1. How to install your new GPU The main parts of this task involve the case and PCIe slot on the motherboard. Most GPUs sold today are connected to the PC via this PCIe slot. A motherboard can have more than one slot, but we'll want to use the first (x16) slot, which usually has the most bandwidth available. An x4 slot is shorter and can be used for other expansion cards (Wi-Fi cards, for example), and secondary x16 slots are usually reserved for additional GPUs or expansion cards . 2. Installing the GPU     1. Power down your PC 2. Switch off the power button on the back side of PSU 3. Extract the side panel. 4. Remove screws from the rear bracket  5. Unlock the PCIe slot clips. 6.Hower the new GPU over the PCI-e slots. 7. Push down the GPU to slide the connector into the slots.
