SATA express vs m2

[serverxeon]

Hi guys,

it's been a long time since i kept up with the hardware scene. thinking of buying a new comp soon, so i have been reading up a bit.

I read that the 'new' thing in storage now is SATA express and m2 interface. they both supports up to 10GB/s?

So, is there any reason one choice is more favourable than the other?
I see m2 drives sold in the market, but are SSD sold nowadays necessarily SATA-express?

Also, a side question.. from a reliability/longevity/heat dissapation point of view, will an m2 SSD drive be more susceptible to damage than the standard SSD?

THANKS!!

currently no SATA Express drive that the moment so dun bother.

imo i still think it depends on ur home environment in regards to get the normal SSD or m2. if the conditions are good (like no dust, air cool room) m2 should be good for u. if its bad den maybe a normal SSD.

Sata 3 the normal sata port has reached its limitations. Most 2.5inch ssds have peaked out its performance of 5xxmbps read/write. Which is why sata express came out with a 10gbps port. But however there is no drives that uses the sata express ports yet atm.

But however, as a need for even faster storage, the ssd market have looked into a faster interface rather than using sata express, they have gone into pcie bandwidth instead.

There are 2 ways to go about it.... one is via m.2. Older m.2 slots like the ones found on z97 has mostly only 10gbps or at most take only x2 pcie lanes. But on most x99 and z170 boards it can support up to 32gb/s. Which in turns need x4 pcie lanes.

The heat of m.2 may be hot if your chassis do not have adequate airflow. It can be hot if you are transferring large files. In normal usage, it should not be hot constantly.

thanks for all the replies!

i did more readings of my own, found out the following:

m2, is only an interface. it actually supports both the SATA3 standard (6Gbps) or PCI-E standard (10Gbps or 32Gbps). It all depends on the SSD you buy.

And, I am thinking of buying the samsung 850 evo, which is a SATA3 drive...
I am more inclined to buying the normal big SATA3 version as opposed to the m2 version, since there is no benefit in using the m2... Do you guys concur with me on my opinion?

You are almost there.

M.2 is an interface just like sata express and sata3. Just difference in bandwidth support.

However m.2 has a few type. 1 is supporting 10gbps and another is the full 32gbps.

There is a difference between sata3 ssd compared to lets say a samsung pro 950 m.2 pcie ssd.

Its 3x as fast as any sata3 ssd available in market.

Whether you need it or not is another thing. Usually fast storage is meant for drawing application usage etc. If you are just gaming, a regular sata3 ssd is fine.

not all Z97 doesn't support pci-e 3.0 at x4 for M.2 aka NGFF... maybe Z87...era...

Hence the word most.

I know your board does lah.

The M.2 version of the 850 evo has no benefit apart from being small and able to fit on the motherboard BUT it's got some bugs that the big doesn't have.

If you just want a 480GB class SSD why not get a Zotac SSD Premium 480GB? http://forums.hardwarezone.com.sg/h...3/zotac-premium-ssd-480gb-review-5360084.html

Also a word of warning, using M.2 SATA will disable one SATA port and M.2 PCIe X4 might disable the last PCIe X4 OR disable 2 SATA ports (depending on the motherboard, some have 2 M.2 slots one of which is connected to a switch between the last motherboard PCIe x4 slot and the other to the bandwidth that can be assigned to SATA ports or M.2) because of Z170's flexible output
