M.2 SSDs : Worth it at all?!

[ClobberXD]

Is it true M.2 SSDs are frighteningly faster than SATA 6Gb/s SSDs? Are there any disadvantages in investing in one? Also any other advantages?

 

Thanks!

They can get up yo 10Gb/s, so yeah they are and the Price/performance ratio is outstanding

10 GB/s in real world? That is awesome!

 

Thanks!

No, don't believe that crap.  Best ones are writing at 1.5-2GB/s.  You will spend a lot more for them.  550MB/s is still fast enough.

Then why in earth are they so pricey? Any other advantages (or disadvantages) ?

 

Thanks!

 

P.S. You have an M.2 SSD?

Really?  I would love to see a single drive that can hit 10GB/s.  Please link it. 

yeah, SATA 3 can get up to 6Gb/s, and M.2 through PCI-E 3.0 can reach up to 10Gb/s

They are still 3-4x faster:  http://www.newegg.com/Product/Product.aspx?Item=N82E16820147425&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-PCPartPicker,%20LLC-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

 

New tech costs more.  They have to pay for all the research and developement.

Plus they don't Need any cables which makes them very nice in SFF builds

No, stop.  Your graph shows a high of 1.8GB/s on the Seq. Read.

 

I have only seen a RAID 0 setup of a ton of Intel NVME drives break 10GB/s.  PCPER guys did it.

it's 10Gb/s i made a mistake, but still seq read/write it much higher dude, it's through PCI-E after all man

Now that's more like it...

Well no... 

 

10Gb/s is pcie2 x2. Pcie3x4 is actually 32Gb/s

[ClobberXD]

Is it worth my money to buy a ~250GB M.2 SSD? Or a regular SSD? 250GB is enough for me, so even if I buy a half-expensive SATA 6Gb/s SSD, I'll stick to 250GB not more.

 

Thanks!

Do take note, whether M.2 port uses SATA or PCI-E lanes for data transfer. Older M.2 use SATA or PCIe 2.0 lanes, which is limited to 10 Gb/s, which is up to 1.25 GB/s (theoretically, overhead not taken into account), if the storage device is capable of that.

 

Newer boards (Z170 and few Z97/X99) use newer M.2 with NVMe (sometimes also written as Ultra M.2), that makes use of PCIe 3.0 x4 lanes with bandwidth up to 32 Gb/s. This is where the newer Samsung 950 SSDs really shine.

only nvme ssd's are faster. Older AHCI drives won't provide a performance increase. I recommend a 950 pro.

That's too expensive... Well, it's NVMe, for God's sake!

 

Thank you for your recommendation though!

you could use any m.2 ssd , but a lot of them usually use the sata bus instead of the pcie bus , which means they will still be around 550-600MB/s. But you have no cables that way.

Yes, that's a common mistake people do with M.2-drives. The basic,  AHCI-drives, are just meant for laptops and SFF-builds and when you want to be really compact. They max out at SATAIII-speeds at 6 Gbit/s. To get speeds faster than that, you'll need to opt for the newer NVMe-drives, which samsung has now released with their 950 PRO-series of M.2-drives.
