SATA Disk Types

Factors that determine Storage Devices

1. Form Factor

It is the chip design parameter that determines which type of hard drive fits the motherboard or cellphone.

Cellphone is a computer.

2. Connections

Type of connection that the device has to fit the HDD, SATA or NVMe drive..

3. Dimensions

Size determine the price and the mass production at the chip factory.

HDD

Drive is considered outdated. 

But this is where I started long before SATA came into existence.

HDD has mechanical parts and has the slowest rate of data transfer.

It's wear and tear is high.

Because it is made of magnatic hardware it can store data for a long time without destruction.

The data transfer is slow due to mechanical parts. This is technically called Latency 

Other BUSS words are Efficiency and Performance. Each device had its own performance quality and efficiency of data transfer.

1. SATA

SATA is considered outdated but I have 3 of them.

120 to 320 to two of 1 terabyte. 

All are functional and I have no desire to go for an expensive m.2 or NVMe devices.

All my academic and non academic data are stored in them. I do not need Google store them in cloud. Infac, I have removed all but the data of the last 3 years.

m.SATA

The letter m in m.SATA stands for mini or smaller, I believe 

Above types slo into SATA interface.

3. NVMe 

They need PCIe slot or interface in the motherboard.

It is the most modern.

NAND flash

NAND comes from the computer terminology the NAND gates of memory blocks. This are modern chips which can be programmed beyond binary program s.

I think the technology refers to Non Volatile Computer Memory.

HDD drives have non volatile memory and the Magnetic Tape can Store more data and they are used by network servers.

Data recovery is possible  with HDD but in SSDs DATA recovery is next to nothing if they are digitally damaged.

1. Form Factor 

3. Mounting Options

Ultimately it boils down to read and write and data transfer which is important in playing digital games

I am too, old for fast games but I promote Linux games but not Windows.

Valve's Steam is ruling the game world.

Solid State Drives were developed to replace old CD/DVD drives. Finding a laptop with CD/DVD ROM is a luxury now.

SATA are defined by the so called Form Factor which defined the interface with which it interact with the operating System and the Boot Loader (BIOS and new GRUB).

1.mSATA

Old laptops

Old SATA interface

2. Mini mSATA

New Slimmer laptops and cellphones.

Old SATA interface. 

3. M.2 SATA

Modern laptop with a slot (interface) to mount the disk.

SATA interface

4. M.2 NVMe

PCIe interface

OCI has 3 generations 3, 4 and 5.

They are not interchangeable.

Non Volatile Memory express.

Speed of 3500 MB in Gen 3

Speed of 7500 MB in Gen 4.

Speed of 14,000 MB in Gen 5.

Motherboard's BUSS support determined the speed of data transfer even though they fit into the same interface or slot.

 

Volatile Memory Blocks

Data are recorded in Units called cells. These cells are stacked one above the other likes bricks.

1. One brick layer is called Single Cell.

.

2. Two brick layer is called multiple not Dual 

3. Three cell layes are called Triple.

4. Four stack layers are called qudreple.
