Therefore, the performance of the hard disk will directly affect the output efficiency of video creators. So, for a video creator, how to choose a hard drive that meets the needs?
Why do video clips need high-performance hard drives?
A computer dedicated to video editing is actually dominated by CPU. In the process of video rendering and editing, CPU needs to do a lot of operations, especially in video output and coding, which consumes more. The performance of CPU depends on the number of cores and main frequency. So choose CPU is relatively simple, try to rely on multi-core multi-thread on it.
The second is memory and hard disk. Generally speaking, for professional computers commonly used for video production, we recommend building multi-channel computers with a capacity of 32GB or higher.
The role of the hard drive is that all the video creation material is read directly from the hard drive into the editing software. If the speed of the hard drive is not fast enough, or if there is something wrong with the hard drive, the editing software will easily stutter or even crash.
Because of the slow reading and writing speed and high delay, the traditional mechanical hard disk can easily slow down the processing speed of the whole machine and become the bottleneck of the whole machine, and the bucket effect will be very obvious.
Why do you need NVMe M.2 SSD? for video clips.
The reading and writing speed of mechanical hard drives is generally about 150MB/s. In contrast, continuous reading and writing of SATA SSD, up to 550MB/s can bring higher fluency to video clips. However, the physical characteristics of SATA SSD make it not an ideal hard disk for video clips.
Limited by the interface, SATA SSD theoretical speed is only 6Gbps, and only supports the old AHCI protocol. The AHCI protocol transmits only one queue at a time, and a queue has only 32 instructions. If we compare the NVMe protocol of interface M.2, we can see why the AHCI protocol is outdated.
The NVMe protocol can provide 64124 queues at a time, and each queue can provide 64161024 instructions. It far exceeds the size of 32 instructions in a single queue of the AHCI protocol. In other words, the NVMe protocol fully unleashes the potential of the transport channel.
In addition, NVMe M.2 SSD is directly connected to the PCI-E bus, that is to say, it is directly connected to the CPU, without transfer, and can distribute the load on multiple queues to the CPU core at the same time, with faster speed and lower delay, which greatly improves the transmission efficiency and makes the system more smooth when carrying out multitasking operations.
What NVMe M.2 SSD can I recommend?
The NVMe M.2 SSD, used for video clips considers nothing more than two factors, one is speed, the other is capacity.
In terms of speed, of course, the faster the better. Therefore, for users with no shortage of money, HOF PRO M.2 is recommended, with continuous reading and writing of up to 5000 MB/s 4400 MB/s (take the 1TB model as an example), which can bring a faster video transmission experience. At the same time, in terms of multitasking capability, its 4K random read and write capacity reaches 760pm 700K iops, far surpasses PCIe 3.0K SSD, let alone SATA SSD.
In addition, HOF PRO M.2 provides two high-capacity options: 1TB and 2TB, which can fully replace SATA SSD and mechanical hard drives.
If it is the pursuit of high performance while taking into account the ratio of performance to price, the continuous reading and writing of M.2 1TB up to 3300 and 2000 MB/s can easily meet the video creation needs of users.
