Nvme vs sata ssd

[EnterClassroom]

I never use SSD before,so now i will buy new ssd which one have the best for me? Im using this ssd for windows boot,ms.word,powerpoint,and open other programs, in my country both ssd have similar price and same warranty

1.samsung 860 evo 500gb

2.adata sx8200 pro 512gb

Is it real nvme runs hotter than sata ssd?

My motherboard is asus x470-f strix

Thankyou in advance and sorry for my bad english

M.2 can have performance decrease due to heat, but even then it will still be faster than a SATA drive.  Basically if you can afford the NVME drive then get that one, it's waaaay faster than sata.

Nvme all the way!!

its not hot under normal circumstance, / load.

even if you make it hot to be slowed down, it shall still be faster than sata ssd, 4x vs 1x  

[Enderman]

There will be 0 improvement to boot times, word, powerpoint, or anything like that.

The only difference is that you will get half the capacity of a sata SSD for the same price.

It is a bad idea to buy nvme unless the programs you use specifically can use those higher speeds.

Programs like video editors, data analysis, and other high datarate tasks.

Just because the numbers are higher in a benchmark does not mean that you should waste money on performance you cannot use.

OP have stated they have similar price.

even so, m.2 is sooo light (8g) and cableless, and admit that the heatsink looks good lol

I mostly agree with you on the real-world performance. However, NVMe drives have been getting cheaper, to the point where you can often get an Intel 660p cheaper than SATA mainstays like the Crucial MX500 and Samsung 860 Evo.

Is it true nvme get more higher temps??

How about the tempa for nvme and sata ssd? Is it true nvme more hotter than sata?

As Intel rep at my location, nothing makes me happier than having this drive as an alternative to the 860 evo. When someone comes in with a relatively recent system looking for a cheap ssd and inevitably walks straight to the Samsung displayer because marketing.gif, it always blows their mind that, yes, I actually can get you a drive that's up to three times as fast for less money. 1tb 860 evo is $147.99 and the 660p is $134.99 lol

To some extent yes, but it's not a problem. If the controller gets hot it will just run a little slower, but it will still be faster than a SATA SSD. And if the flash memory gets hot, that is actually beneficial for data retention.

Yes they get hot, which is why you need to put a heatsink on it if you want it to have a decent lifespan.

Many recent motherboards have a piece of metal that has thermal pads on it that contact the M.2 drives.

That only applies when reading or writing data.

There is higher probability of data loss and flipped bits when the drive temp is higher.

There's a reason consumer SSDs are usually only rated for 50-60C.

It is NOT safe for an SSD to reach 80 or 90+ degrees.

Not only will that cause flipped bits, it can also kill the drive sooner.

660p has a bad endurance rating. Only 200tbw for 1tb drive. Its fine if you just game and surf, but avoid if you often edit large files.

 

At least here in EU corsair mp510 is the best option. 205€ for 960GB with 1700 tbw. 970 evo has 600tbw and costs more.

That applies to DRAM, not NAND flash. Data retention for NAND flash is better the higher the temperature.

Endurance rating is not indicative of actual endurance. It's just what their warranty covers. And even 200 TBW is quite a lot; I have an SSD from 2012, and I've only written 36 TB to it.

No, it is not.

Take a guess why SSDs have a max temperature rating.

https://www.anandtech.com/show/9248/the-truth-about-ssd-data-retention

"as the temperature increases, the electrons escape the floating gate faster that ultimately changes the voltage state of the cell and renders data unreadable (i.e. the drive no longer retains data). "

This is called flipped bits.

That refers to when the SSD is unpowered:

The conductivity of a semiconductor scales with temperature, which is bad news for NAND because when it's unpowered the electrons are not supposed to move as that would change the charge of the cell. In other words, as the temperature increases, the electrons escape the floating gate faster that ultimately changes the voltage state of the cell and renders data unreadable (i.e. the drive no longer retains data). 

Meanwhile, it's the other way around when the SSD is powered:

 

Quote

For active use the temperature has the opposite effect. Because higher temperature makes the silicon more conductive, the flow of current is higher during program/erase operation and causes less stress on the tunnel oxide, improving the endurance of the cell because endurance is practically limited by tunnel oxide's ability to hold the electrons inside the floating gate.

Yes I know, that's why I linked the article, so you could read it.

It is not healthy for it to be that hot.

Also heat only offers an improvement when powered at reasonable temperatures, like 40 or 50C.

If you put any SSD at 90C+ it will certainly have decreased lifespan.

If you put it at like 120C it will instantly die.

 

Try imagining what happens to the silicon when it is so hot that it is so conductive that the current flow is extremely high.

Did you know that what kills electronic components is current, because it causes them to heat up?

Silicon is supposed to be a semiconductor, not a conductor, so having high conductivity all the time is not good because it needs to close the gate too.

Okay, that is true. Extreme temperature will harm the SSD. Both controller and NAND flash. It's just not really going to happen to the NAND flash in practice, the controller runs hotter.

 

The article only looks at temperatures up to 55C, for comparison.

Yes that's my point, 55C is fine but I've seen M.2 SSDs get MUCH hotter than that.

The case needs to have good airflow, preferably flowing over the NVME SSD.

Best case scenario is you stick a heatsink on it.

An LMG staff member should know better than to make blanket statements like that. You aren't even using accurate terms. Modern consumer drives either use the SATA or PCIe interface.

 

A PCIe drive (sometimes called an M.2 drive, even though that's just the form factor, or NVMe drive, even though that's just the protocol) generally has much faster sequential speeds, but the random read speeds, which is what matters most to the average user, may or may not be faster than a SATA drive. I've seen PCIe drives that were slower than cheaper SATA ones. Unless you're managing large files regularly (at least 1GB), such as with video editing, you probably won't notice a difference.

The controller is literally millimeters away form the flash memory.

So you dont edit large files often. Read before reply...
