3.3 – SSD Flashcards
SSD = Solid State Drives
flash chips to read & write data electronically
in SATA & M.2 form factors
—Most motherboards have SATA, not everyone has M.2
SSD = Solid State Drives
Advantages
o Ideal for mobile since there are no moving parts
o FASTER at reading / writing data
SSD = Solid State Drives
Disadvantages
o MORE EXPENSIVE than traditional HDDs
—Price per GB is how we determine the value of the drive
o Limited write cycles
SSD Connectors
M.2 Connector
NVMe [M.2]
SATA [M.2]
SSD Connectors:
M.2 Connector
supports PCIe & SATA
o Have quickly become the preferred SSD form factor
o Smallest drive form factor
o Replaced the older mSATA standard
o Supports SATA & NVME SSD
o Formerly NGFF = Next Generation Form Factors
o M.2 slots are keyed to identify what type of device / drive is supported
SSD Connectors:
NVMe [M.2]
runs on PCI Bus
o MUCH faster
o 4 lanes
SSD Connectors:
SATA [M.2]
runs on SATA Bus
o Slower
o 1 lane
NVMe = Non-Volatile Memory Express
o PCIe based SSD drive which provides the BEST performance
o FASTEST SSDs on the market
o Available in different lengths
