And in fact, historically, the earliest SSDs did not use flash storage.
Flash Storage vs SSD - Apple Community
Future SSDs might also use a medium other than flash. Most solid state drives use the same form factors as HDDs. This makes it easier for users to migrate from disk-based storage to solid state storage. Enterprises can purchase individual drives or SSD arrays already populated with drives. SSDs have been around quite a bit longer than flash.
EAROMs also appeared in some early video games, but the technology never really took off. Like flash, RAM is fast. This poses some pretty obvious problems in the case of a power outage, so many of these early SSDs had battery backup systems.

Over that time, they also experimented with other technologies that could be used to create SSDs. In the early s, Intel created a product called Bubble Memory that generated a lot of buzz and was incorporated into some early PCs, including the Apple II. But its designers ran into technical problems when trying to expand the capacity of Bubble Memory, and Intel soon abandoned it. Around the same time that Bubble Memory seemed like the hottest new thing, a Toshiba employee named Fujio Masuoka came up with the idea for flash memory. He presented his invention at an industry convention in , and in the late s, the first flash memory products hit the market.
Flash-based SSDs began to be available in the early s, but the price tags were high. That exorbitantly high price tag put flash out of reach for most applications, and it also wasn't as fast as RAM, both of which were points against the technology.

However, the non-volatile nature of flash made it appealing enough that researchers continued developing it even as they sold RAM SSDs. Then in the s, the price for flash began to drop to the point where enterprises could afford to replace older storage technologies, such as HDDs and even tape, with faster SSDs based on flash storage. As previously stated, today, nearly all the SSDs on the market are based on flash technology, which is a big part of the reason why people sometimes think that "flash" and "SSD" are two words for the same thing.
However, it might not always be this way. Manufacturers are continuing to look for new alternatives to flash. However, like flash in its early days, 3D XPoint is still extremely expensive, and few products currently on the market are using it. So far none of these other options, including 3D XPoint, has become a major part of the storage market.
Only time will tell whether one of them becomes the next flash or if they go the way of Bubble Memory.
HDD, SSD or Flash Storage? Which storage option is the best for the Mac Pro?
For the foreseeable future, most SSDs will continue to be based on flash storage technology. And that likely means that much of the storage industry including, on occasion, EnterpriseStorageForum will continue using the terms "flash" and "SSD" interchangeably. They are both one and the same, technology wise similar. SSD is a drive in itself.
Flash is also similar to SSD but this uses no power to store data. Essentially both kinds do not use a mechanical moving parts to store and retrieve data. To many people the terms are more or less interchangeable but SSD refers to the unit itself the drive whereas flash storage refers to the memory chips that are contained in the unit. Flash storage also refers to the technology itself. That's like asking "what are the differences between an electric car and a hydrogen fuel cell?
The Difference Between SSD and Flash Hard Drives
If the SSD is non-volatile i. SSD's not based on flash storage would need constant power to retain their data. A Solid state drive, or an SSD, is a lot faster in terms of read and write speeds that a conventional hard drive. Posted on Jan 16, Page content loaded. Jan 16, Flash storage in a Mac refers to storage that is integral with the motherboard. Both devices are more or less identical except for the physical connection. Flash storage may be faster than some SSDs, but not all. Yes, that's correct. Unless the flash drive is implemented as a device that is plugged onto the motherboard - a daughterboard - it cannot be removed and replaced.
It would not be upgradeable.
Jan 16, 2: Can you please, very please, post two pictures on how a Flash Storage integrated on a motherboard, and another picture of how a SSD is just plug on a motherboard. Jan 16, 3: The bottom device is what a Retina may carry as solid state storage. OWC makes it for those who scrimped when they purchased their Retinas, only to discover they couldn't live in GB.
