M.2 vs U.2 – Velocity Micro Weblog

In earlier posts, we’ve coated the distinction between sure storage interfaces like SATA, M.2, and NVMe. With the continued proliferation of U.2 on greater finish motherboards and newer chipsets, the time has come to check M.2 vs U.2 as properly – how are they similar, completely different, and which is greatest for you?

What’s M.2?

M.2 is usually used to explain each the SSD type issue and the connection that SSD makes use of to hook up with the motherboard. M.2 drives are small – concerning the dimension of a 5-piece pack of gum and might are available SATA variations just like the Essential MX500 and NVMe variations just like the Samsung 980 Professional.

What’s U.2?

U.2 is one other SSD type issue as soon as relegated solely to excessive finish workstations and server motherboards however has turn out to be extra mainstream with not too long ago launched chipsets. U.2 drives use

an identical however distinctive motherboard connection to M.2 however can be found in 2.5” type elements like most SATA SSD drives. They share a number of the identical efficiency traits as M.2 as we’ll talk about shortly, however are usually not interchangeable.

M.2 vs U.2 – How are they the identical?

Though they use distinctive port varieties, each NVMe M.2 and U.2 use the PCIe bus with x4 lanes to attach electrically to the PC. This implies each have the identical potential bandwidth that interface permits – 32 GB/s for PCIe 3.0. So although there could also be some efficiency gaps from mannequin to mannequin when evaluating M.2 and U.2, each forms of drive will probably be in the identical vary as a consequence of a scarcity of limitation from the bus like a SATA drive can have.

M.2 vs U.2 – How are they completely different?

  • Motherboard connection – Though each M.2 and U.2 talk to your motherboard by way of the PCIe bus, the port they use to bodily connect with the motherboard is completely different. Whereas M.2 drives are positioned immediately on the board, U.2 connects utilizing a cable that appears like a double decker SATA. The drive itself sits within the exhausting drive cage with it’s different 2.5” brethren. As a result of they use much less bodily house motherboard producers can typically embody extra U.2 ports than M.2.
  • Type issue – Although M.2 and U.2 use the identical sort of flash reminiscence storage, they arrive in completely completely different type elements. M.2 is a small, flat, board whereas U.2 is the two.5” type issue you’re accustomed to from most SATA SSDs.
  • Capability – Due to the bigger type issue, U.2 has a better storage capability – round 4TB+ in comparison with the 2TB max from most M.2.

Which is greatest?

That reply depends upon you. For many customers with common storage wants of 2TB or much less, an M.2 NVMe just like the Samsung 980 Collection is quick, broadly out there, and the only option. However for customers in want of extra excessive storage in both a single drive or RAID array, the scalability of U.2 is probably going interesting, assuming the motherboard helps them.
