Why you need the Micron M550 for your laptop

An SSD card otherwise known as a solid-state drive is a computer data storage device that uses flash memory chips and it doesn’t have moving parts. It keeps data safe and performs faster than HDD cards (hard disk drive). If your laptop doesn’t have an SSD card then you are missing out on fast performance and a number of other features that will save your time.

An SSD card doesn’t have any moving parts so data stored inside will be safe even when it falls to the ground. Because there are no moving parts inside an SSD it won’t come up with any mechanical problems.

Laptops that rely on HDD cards have to supply energy to the card before it works. A laptop that uses an SSD card wouldn’t sacrifice any power to in order to service the SSD card because it doesn’t come with a motor like we find inside an HDD card.

A laptop that uses SSD card has faster read and write speeds than a laptop that uses HDD card. there is the need for an HDD card to spin before it works and it slows down the read and write speed. An SSD card uses flash memory chip and data read and write speeds happen instantly and that’s why it is fast.

 Maybe you have heard some weird noises when carrying out a graphic demanding task on your laptop well sometimes it’s the HDD card inside. Using an SSD card like the Micron M550 guarantees almost zero noise because we don’t have any parts moving. It also generates less heat an SSD card is better if you want your workflow to be faster.

Selecting the Best SSD Drive for your Laptop 

The Micron M550 looks almost the dame with its predecessor the Micron M500. It has a smooth and refined metal finish that is durable. The solid-state drive is finger proof thanks to the metal finish. At the front we have some stickers that labels the drive alongside Microns Logo and model number.

We have screws by the side of the Solid-State drive that will be used to mount the SSD drive. It comes in a slim profile and its just 7 millimeters thick. The Micron M550 will fit in many ultra-books and many other laptops.

We have the SATA power and data connectors at the front of the SSD card. the 1TB variant uses the Marvel 9189 controller as well as 16 NAND die, each NAND die is 64GB. If you are wondering what a NAND die is then it’s the highest level of a NAND flash component.

The successor to the M500 also offer more storage capacity for example you get 514 GB instead of the 480 GB model on the M500 line up. We have three form factor that include the 2.5 inch, mSATA, and the M.2 form factors that give you an option depending on the type of laptop or system you might want to pair it with.

The SSD drive has three years warranty and it comes with a number of other hidden features like sleep support, native write acceleration, and garbage collection. The read speed is 550MBps at maximum and it has a write speed of 500Mbps at maximum which is pretty decent.

Here are 6 key points for selecting the Micron M550 for your laptop

Good Build Quality

The SSD drive has a metal finish that makes it cold to the touch and also durable. It has four screws that allows it sit inside any Ultrabook or laptop. Micron made the SSD drive slim at 7mm and it will work perfectly fit inside many laptops. the SSD card is versatile and comes in different form factors.

Low Power Consumption

The SSD drive doesn’t have any moving parts unlike we have inside a hard disk drive. It works continently and doesn’t make any sound while working. The Micron M550 doesn’t consume power because it doesn’t have any moving parts. When idle the SSD drive measures 1.0 watts of power when in use it reads between 2.46 watts and 4.37 depending on what it us been used for.


The Micron M550 comes with 3 years warranty which is really amazing. During the first three years of usage if there should be any technical problems with the solid-state drive then you can qualify for a replacement because of the warranty. You need to keep the stickers and box intact however because if they are not available they might deny you the warranty.

NAND Technology

The Micron M550 uses a NAND flash memory that makes it perform fast while keeping your data safe. they added NAND die which is the highest level of NAND flash component. It performs consistently and it also has some smaller chips that adds to the NAND flash to keep the performance consistent all the time.

Great Performance

The SSD drive is going to deliver top notch performance with a read and write speed of 550MBps and 500MBps. This is actually one of the few SSD drives out there that come in at an affordable price and still deliver great performance. the 4K read and write speed is also decent although the SSD card was not made to give industrial level of performance.

Different Form Factors and Storage Options

The micron m550 come in three form factors that include an M.2, mSATA, and 2.5 inch. You also get to select the different storage options available that start from 64GB up to 1TB for the 2.5 variant while the mSATA, and M.2 variant max out at 512GB.

 Having different form factors available gives users options depending on where they want to fix the SSD card. more storage option would also give you room to choose the storage capacity you want.

A Closer Look at the Micron M550

We have 8 screws securing the drive four on the case and four for PCB. The high-performance Marvell controller tends to get warm after a while but Crucial added some thermal pads to allow the casing dissipate heat from the controller and DRAM cache. Crucial opted for a slightly improved controller by Marvell for better performance and lower power consumption.

The 512 GB variant is equipped with 16 modules of 128GB 20nm synchronous MLC NAND for a capacity of 512 GB. For DRAM buffer they used a single 4GB module of micron LPDDR2 that gives the drive an ideal 512 MB DRAM buffer.

The SSD drive also includes power loss protection capacitors which will allow the drive to flush data from its volatile DRAM cache into non-volatile NAND in event of sudden power loss. This is an enterprise grade feature that is almost never found on consumer-grade SSD drives.

The new Marvell controller that was used inside the SSD drive gives it better benchmarks and performance result during tests. It addressed some of the issues that consumers had with the Micron M500. Another important thing that Crucial addressed with the M550 is the fact that they settled on completing the storage instead of 418 GB on the M500 you are getting the complete 512 GB on the M550.
