HDD vs SSD vs M2 Drives
Welcome to the innovatory new age, the cutting edge of modern technology! You’re searching for a kind of drive that many people don’t even realize exists. Technology is moving and changing daily, and we need to evolve with it. So, let’s take a look at the differences between HDD, SSD and M2 Drives.
For many years PC’s primarily used mechanical hard drives which have great capacity potential but slow speeds. The maximum data transfer speed of mechanical hard drives is less of an issue than the slow seek times due to the spinning disk mechanism in a mechanical hard drive. The actuator arm needs to position itself in the right location on the track to find the data and this is known as seek time. Modern hard drives have a seek time of around 5 to 10 milliseconds an SSD has no moving parts which are why it’s called a solid-state drive.
With SSD, since the NAND flash doesn’t have to physically move to find data, there is no seek time. Instead, the delay in finding data for SSDs is known as latency and is only around 30 to 100 microseconds. This is one major reason why solid-state drives provide such a massive boost in performance over mechanical hard drives. Data requests are handled much more quickly allowing for snappier performance and faster loading times. However, the problem with traditional 2.5inch SSDs is that they are stuck on an interface created from mechanical hard drives known as serial ATA. With SATA the third generation of this interface was first released in 2009 and has a maximum theoretical rate of 600 megabytes per second. SATA 3 is perfectly fine from mechanical hard drives which have slow seek times and a sequential transfer rate of around 180 megabytes a second. While this interface was also good for SSDs initially, they quickly maxed out their transfer rate and became bottlenecked. NAND flash can go much faster therefore replacement was needed.
A new interface created specifically for SSDs known as MDOT 2 arrived on the market. An MDOT 2 site connects to a motherboard directly which also provides it with power. M2 can support SATA interface SSDs in this new form factor but it is brought about a new high-speed SSD known as NVME or non-volatile memory Express. It reduces latency even further to around 10 microseconds and it also increases the maximum transfer speed to 3 gigabytes a second. What NVME can transfer in one second would take the average of the mechanical hard drive 17 seconds that’s 17 times faster. Make sure the width and especially the length will work in the space available for the drive. Most will be 22mm wide, but the length varies: 42mm, 60mm, 80mm, 110mm are the most common sizes.
What it comes down to is speed. HDD is for your budget consumers who do not require fast speed and want to download their own files. SSD are for the speed warriors, who need to work at a faster pace such as video editors or sound engineers. The latest in speed and storage technology is the M2 Drive, so this would be to successfully run small businesses if you want to keep up with the latest technology, especially as it is always changing and progressing.
