What is the difference between an EMMC and an SSD?
Sometimes you can’t tell because they both store data on electronic chips no matter what the storage medium. The only way to differentiate them is by looking at their speeds and capacities.
An EMMC has a slower speed than an sd card, but it also stores more data. On the other hand, SSDs have higher read/write speeds than EMMC which makes them ideal for certain tasks such as gaming or video editing.
so why are we talking about the EMMC today because you can actually find it in many newer Chromebooks as well as entry-level Windows 10 laptops can also find any mini cell phones as well as tablets?
What is EMMC?
Benifits of EMMC
So let’s look at some of the benefits and some of the characteristics and compare those to other drives the EMMC embedded multimedia cart architecture puts the MMC components that is the flash memory plus their controller into a small ball grid array BGA IC package that measures only 32 by 24 millimeters in size it is used in circuit boards as an embedded non-volatile memory system.
This is normally different from other versions of MMC as this is not seen as a typical user-removable or upgradable card but rather a permanent attachment to the circuit board.
Almost all mobile phones and tablets use this form of flash for main storage up to around 2016 until the U FS or universal flash storage started to take control of the market.
Emmc Vs the SSD speed
The latest version of the EMMC standard the just D 84 – B 51 by J deck is version 5.1 released back in February 2015 with speed rivaling discrete SATA based SSDs at 400 megabytes per second that’s not necessarily a slow speed as SATA SSDs will top out around the same transfer speed.
However, it’s not just the overall transfer rate that determines how a device’s performance will be affected eMMC storage usually operates with fewer memory gates than an SSD.
it can still deliver at the same speed just not at the same volume let’s think of this as a highway the more lanes the more cars you can move at a time EMMC uses a single lane.
while an SSD uses a multi-lane highway as seen here so you go the same speed on either one but the line to get onto the road will be nearly slow on like multi-lane highway so if you want the fastest transfer speeds of data you would go with a PCI Express SSD.
so why don’t we just all have these faster storage units in all of our devices?
Well that comes down to a few reasons first off is cost makers of laptops and other portable devices have stiff competition and cost is a big factor EMMC storage costs much less than PCI Express SSD or any SSD storage for that.
EMMC vs Solid States Drives Energy Consume
For longer battery life for laptops, EMMC runs from 1.9 volts to 3.6 volts while consuming between 4 and 7 watts depending on the load emptier.
Solid State Drive Energy Consume
Solid-state drive varies from 5 to 8 watts depending on the load next is read/write speeds the newer EMMC 5.1 running at 200 megahertz at 3.6 votes is faster than the earlier e MMC e-versions but not as fast as the m2 SSDs.
