If you're new to flash storage in general, the class 20 should be plenty sufficient for your needs. Sure there will be more performance from the Class 40, but you NEED to have a good motherboard to take full advantage of it too (assuming the SSD supports 4 lanes which a class 40 should).
People also ask, what are the different classes of SSD?
What Do The Different Classes of Solid State Disk (SSD) Mean?
|CLASS ||Marketing Name ||Sequential Read/Write |
|20 ||Mainstream ||500mb/300mb |
|30 ||Performance ||550mb/350mb |
|35 ||Performance ||800mb/1200mb |
|40 ||Performance ||1500mb/350mb |
Also, is PCIe faster than SATA?
PCIe provides a faster interface speed than SATA. An SSD connected via a PCIe 3.0 x16 interface can have a link speed of 16 Gb/s. In contrast the SATA 3.0 standard only provides 6.0 Gb/s. Solid State Drives (SSDs) come in a number of different form factors and are available with different interface connects.
Is M 2 an SSD?
An M. 2 SSD is a solid-state drive (SSD) that conforms to a computer industry specification and is used in internally mounted storage expansion cards of a small form factor. M. 2 SSDs are designed to enable high-performance storage in thin, power-constrained devices, such as ultrabook and tablet computers.
What is a Class 50 SSD?
Class 50 drives are the highest performing SSDs offered on Precision workstations. They provide some significant performance gains over Class 40. Many are based on MLC flash, while some incorporate newer, faster technologies such as 3D Xpoint.
