About me

Hi I am madhankumar;

Firstly I would like to thank you for giving me this opportunity to introduce myself.

I am madhan from  kumbakonam tamil nadu. I completed my BCA from Annai college  of arts and science it affiliated to Bharathidhasan university with 68.5% and i have completed my +2 from government higher secondary school with 85%.I have done my schooling from same school. Now i am studying MCA at government arts college in kumbakonam. 

having working experience in a bluetech hardware and networking service 

Want to know who i am 

just see here

M2.SSD INTRODUCTION

M.2 SSD

An M.2 SSD is a solid-state drive (SSD) that conforms to a computer industry specification written for internally mounted storage expansion cards of a small form factor. The specification, originally known as the Next-Generation Form Factor (NGFF), is pronounced M-dot-2M.2 SSDs are designed to enable high-performance storage in thin, power-constrained devices, such as ultrabook and tablet computers. They are generally smaller than mSATA SSDs, for which they are intended as an alternative.

        

The M.2 form-factor specification was defined by the PCI Special Interest Group (PCI-SIG) consortium of technology industry vendors and the Serial ATA International Organization. The M.2 specification supports applications such as Wi-Fi, Universal Serial Bus (USB), PCI Express (PCIe) and Serial ATA (SATA

M.2 SSD vs. mSATA

M.2 is commonly referred to as an mSATA replacement, but mSATA SSDs still exist and will probably continue for some time in laptop platforms that support that form factor. Because M.2 and mSATA cards are different form factors and have different connectors, they cannot be plugged into the same devices.

M.2 SSDs are faster and store more data than most mSATA cards. M.2 SSDs support PCIe 3.0, SATA 3.0 and USB 3.0 interfaces, while mSATA only supports SATA. M.2 SATA SSDs have similar performance to mSATA cards, but M.2 PCIe cards are faster. SATA SSDs have a maximum speed of 600 MB per second, while M.2 PCIe cards can hit 4 GB per second.

PCIe support also allows M.2 cards to take advantage of the nonvolatile memory express (NVMe) protocol, which brings a large performance advantage over other types of interfaces due to reduced latency, increased IOPS and lower power consumption.

As of early 2017, the largest M.2 SSDs support 1 TB of capacity, more than any mSATA drives.

M.2 connectors support four lanes of PCIe bandwidth, or one SATA or USB lane.
