Samsung 850 Evo or 850 Pro?

[Jetster]

If your constantly doing writes because you work on video, music, programming or modeling then get a PRO smaller SSD. Then use your EVO 2Tb for storage. Just back your shit up

Eh, I've decided. I'm buying the 850 Pro 2TB. I have enough of this. Was hesitating a bit still, but yesterday avast! fucked up my entire SSD cache and filled it with absolutely random files after doing a full system scan. It's still a holiday today so I have to wait till tomorrow, but this is it. If I'm going to spend this kind of money on storage, 600€ or 860€, what difference does it really make...

Besides, by selling my 2TB HDD and the M.2 PCIe SSD, I'll get back part of the difference.

Entire month on pasta with sauce made from that other spare boot.

 

[RejZoR]

Just when I wanted to order the drive, damn store bumped up the price by 20€. Fuck no. Now I'm gonna wait till it gets back to price I looked at originally or try to find another store. Argh.

Good. Found another German store that allows wire transfer and had same price as the original shop. This baby is now officially ordered

Been living with my new Samsung 850 Pro for few days now and I must say it's pretty badass.

Entire Windows 10 install with all updates took like 15-20 minutes. I shit you not. The longest thing during boot now is waiting for BIOS to even post. After that, it takes like 5 seconds to fully responsive desktop. The weirdest thing is I have no HDD grinding now. I'm already used to it from laptop that has SSD for ages, but it's still so weird. I guess we kinda developed PTSD for HDD grinding XD

What I also really like is Samsung Magician app. It's nice, clean and entirely contradicts Samsung's past crap software. Also, using Rapid mode because why the hell not. I got tons of RAM and supposedly, it's not prone to data loss since it's mostly smart DRAM read cache and less write cache.

It was a very expensive purchase but I think it's great and I'll probably justify it even easier over time as I use it even more. I just have to shake off the "NAND write wear anxiety". The drive is guaranted to survive 300TB of writes and when they absuse tested its older brother 840 Pro at Tech Report, it died at over 2PB. 2 PETABYTES! I sometimes wish I'd be an ignorant normie so I wouldn't worry over things because I understand them too much XD

the samsung 850 pro. they have a "magic" about them that makes them FAST!!!!!.... really, i have a 1TB 850 evo and while it is great, it does not feel "silky" that the samsung 850 pro has (specifically the 256GB) (i am assuming that the 1TB samsung is the "same" as the 256 pro)

of course, they measure the same (evo vs pro) but on an old laptop that i was upgrading to win 10 from win 7, the experience was silky smooth (lol, the upgrade was a nightmare, had to disconnect the wifi, use an usb iso, and disconnect from the internet completely)...

so go for the 850 pro... ( of course the 1TB has MOAR STORAGE... lol)

Glad ya like it , did everyone forget boot times are crazy lol.

 

[RejZoR]

I now have to figure out why it takes so long for Sabertooth X99 to even post. When I fire it up, it spins the fans up at higher RPM, slows down, beeps as it posts, shows the boot logo and then starts loading Windows. And out of all boot time, 80% of it is taken by the motherboard posting. Hm.

Technically 3D V-NAND is TLC NAND and they are both MLC NAND's. Difference between 3D-V and TLC is how it is made. The 3D-V still has 3 cells, but they are designed with 3rd dimension where TLC is planar. What this means is that 3D-V is less prone to getting stuck, resulting in much more reliable and durable NAND memory. Where TLC cells tend to get stuck faster (an unavoidable side effect of toggling NAND cell states constantly). Plus, since it goes into 3rd dimension, you can fit more of it on the same surface size.

Actually, it's just layers of NAND cells. It's far simpler than making it 3d on the cell basis, they are literally just standard MLC or TLC NAND cells stacked. The Evo is VNAND in TLC (3bits per cell) form, while the Pro is MLC (2bits per cell) VNAND. They are both about 32 layers stacked IIRC, allowing a much lower process node (and thus higher endurance).

There's a great writeup on this at anandtech. I'm sure google could find it.

 

[RejZoR]

Actually 850 drives are intentionally using older (and larger) 40nm MLC NAND to enhance endurance. But since it's V-NAND, they could stuff same capacity into existing package physical volume as planar 19nm TLC's used by other NAND makers.

As far as I know that's not exactly true. V-NAND uses taller cylindrical shaped cells where normal TLC uses lower, square shaped cells that are more prone to wear and failure. At least that's what I gathered from some Samsung schematics which I can't find right now.

That is possible. However the main benefit of longevity comes from the lower process node. This is a well noted trend in nand, in which process node shrinks reduce reliability. The ability to use a larger node is thus a huge benefit.

 

[RejZoR]

Node size and shape of the cells. These cylindrical ones are supposedly more resistant to wear when locking and unlocking electrons (or whatever they store in them) to store data. When loading and discharging, it wears way less than traditional NAND cells.

I need help, I search for serial number of Samsung 850 EVO 1TB 3rd GEN 48 layer TLC V-NAND.
From 2016 I think. If serial number is same with previous version than how to recognize him?

It should be on the sticker on the back side of Samsung SSD.

 

[Vlada011]

I figure out, looks like blue V-NAND on front side.
But anyway I need him for gaming drive and I would use even 10% slower but bigger.
But 2TB SSD are to expensive. No below 300$. 850 EVO 1TB is now 260 euro and 280 euro cost 950 PRO.
512GB M.2 + 1TB SSD SATA III are enough for my need. But 48 layer have 40% smaller power consumption if someone one day decide to remove them in gaming
laptop could save a lot of money if choose cheaper gaming laptop with HDD and if power consumption is less even better.

List of my urgent need upgrades continues...
But in 2016 only GPU, M.2, SSD. That's it.
1080, 960 series M.2 and 850 EVO and my computer is ready.

Realistically you are not going to notice a difference. The difference between 2 top performing SSD is quite negligible in all real-world scenarios. That being said the performance of the Pro is going to be a little bit faster and have better prolonged write reliability and longevity.
