"ADATA’s 2 TB XPG SX8200 Pro is already available in the US for $289.99"
If recent price drops are anything to go by, this should be at price-parity with the Intel 660p by Christmas. (which means, *you* get a 2TB! And *you* get a 2TB! And *you* get a 2TB! *Everybody* gets a 2TB! because it will be way *better* than the 660p...)
660p is QLC nand and as a result will always use half of the TLC counterparts. Considering both NANDs are made by Micron (what used to be Micron/Intel JV), I imagine pricing will always scale similarly... $180/$300 for 2TB QLC/TLC.
So if you can get $200 2TB TLC using micron NAND in BF’19, I am betting the 660p 2TB QLC will be ~$120.
why half? qlc/tlc = 4/3 and it doesn't include controller (which is more complex for tlc if you are goinf to reach the same perfromance). so for $200 tlc drive, equivalent qlc should be $170-180
2Tb 660p is selling now for $180 in US. I am not saying it scales perfectly, ergo the ~ sign. But controller and Dram is not $100, probably closer to $20-30, rest is NAND.
Voltage levels double each time, stored bits do not. SLC->MLC 1bit->2bits = double MLC->TLC 2bits->3bits = 50% more TLC->QLC 3bits->4bits = 33% more This is bits/celll, but cell sizes are not necessarily the same (or even using the same tech).
So far, biggest bit production boost has been from added layers in 3D NAND.
The number of levels double but the number of bits does not. 4 bit per cell vs 3 bit per cell is only 33% more bits per cell. If you have flash with 1 billion cells then if it is TLC then it would be 3 Gb and if it is QLC it would be 4 Gb.
You might also want to mention that this drive is a 2.5 inch form factor.
OTOH, imagine four of these in a 1.0 raid array using the Highpoint SSD7110 raid controller.... And up to a total of 16...
Plus up to a 6TB raid of nvme m.2 2280 drives. For those that feel the need for more speed (face it, this drive sucks at write performance...) you can also/or boot from this array in raid 0, 1 or 5 configurations.
I don't think this was a very carefully researched posting: it gives you LESS information than a 2 minute Google search would turn up.
For instance the vacuum on information on the DRAM ("capacity unknown"), and the pSLC Cache ("Supported").
Just looking at past reviews by Anandtech itself would give you more information.
And a lot of what it says is wrong, or at least misguided: (1) "ADATA’s XPG SX8200 Pro is a version of the company’s Gammix S11 Pro without an aluminum heat spreader, which ensures compatibility with laptops"
Actually, no. The Gammix S11 Pro is a version of the SX8200.
And as more knowledgeable reviewers have mentioned, all of the M.2 format can suffer from thermal throttling, so anyone using this SSD should either add a heat exchanger (not actually a heat "spreader") or make sure it's got a fan's output directed at it.
(2) "What is a bit more surprising is that some manufacturers are also expanding their existing product lineups with 2 TB SSDs as NAND prices continue to fall"....
Eh? Hmmmmmm....so Mr. Shilov, what's the logic here? It's pretty obvious that as NAND prices fall, it makes larger SSD's more attractive. The main point to look at is $/GB.
As one can see from reading Anandtech's own reviews (by other Reviewer's than Mr. Shilov), you can see that it you want >= 2TB of storeage space available, in terms of internal and external drives, you're MUCH better with as much of it on SSD (Sata or PCIe) as you can afford.
And for the 2TB value, even if a lot of laptops don't have this available internally, what percentage of laptop users with machines younger than 5 years old have LESS than 2TB capacity: internal plus external?
This idea about SSD drives was that even older models could benefit from upgrading to one. And about 3 years ago, anything > 512GB was quite expensive, but now, there's a huge number of very cheap 1TB models available: dirt cheap.
Cheaper than a 1TB HDD was 6-7 years ago in fact.
And you can get a 2TB model for not much extra. In many cases, if you look at the cost of putting a 1TB SSD inside, and a 1TB USD HD externally, you spend LESS getting a 2 TB model.
Do the math, and you'll see.
So what would be nice if someone else at Anandtech did a few more tests on 2TB models, and generate real data. And don't write stuff like this.

nice, this has been the best deal for a high performance 1TB drive in Canada for almost a year, was really hoping a 2tb would release!voodoobunny - Monday, August 12, 2019 - link

It Doubles between version because SLC:MLC:TLC:QLC is an increasing bit count. 1 bit, 2 bits, 3 bits, and 4 bits. Meaning 2:4:8:16 voltage level.frenchy_2001 - Tuesday, August 13, 2019 - link
Voltage levels double each time, stored bits do not.SLC->MLC 1bit->2bits = double
MLC->TLC 2bits->3bits = 50% more
TLC->QLC 3bits->4bits = 33% more
This is bits/celll, but cell sizes are not necessarily the same (or even using the same tech).
So far, biggest bit production boost has been from added layers in 3D NAND.
PEJUman - Tuesday, August 13, 2019 - link
4 bits is 16 levels = 0000,0001,0010,0011,...11113 bits is 8 levels = 000. 001, 010, 011, ... 111
Bits are binary system, each digit increment meant doubling.
Similarly, decimal (0 thru 9), where each digit increment meant 10 fold increase.
Almost all of the modern NAND are 3D, with layers varying from 32 to 96, and soon beyond.

have been using the 512GB version since this May. can confirm this is a real good hardwareCharlie22911 - Tuesday, August 13, 2019 - link
I want a 4TB NVME drive so bad, I’d love to get rid of my external spinning rust. I don’t even mind paying a premium for it, just give me the option.Greg100 - Tuesday, August 13, 2019 - link
Here you are......but why bother 4TB NVMe?
The cheapest NVMe per TB is:
Western Digital Ultrastar DC SN630 - 7.68TB
In Germany you can buy it for:
€ 978,23 - Mindfactory
€ 978,24 - Compuland
€ 978,25 - VibuOnline
€ 978,26 - DriveCity
€ 978,28 - Klarsicht IT
4TB SSDs are more expensive per TB than above 7.68 NVMe SSD.
If you find something cheaper let me know.
Greg100 - Tuesday, August 13, 2019 - link
You also need U.2 to M.2 cable from Intel # J15713-001, if you do not have MB with U.2 port.Greg100 - Tuesday, August 13, 2019 - link
Prices include 19% tax (VAT).Greg100 - Tuesday, August 13, 2019 - link
It’s also cheaper per TB than Samsung SSD 860 EVO 4TB SATA SSD!!!€ 591,75 - Mindfactory
€ 591,76 - Compuland
€ 591,77 - VibuOnline
€ 591,78 - DriveCity
Shame on you Samsung!

Greg100 - Wednesday, August 14, 2019 - link
2.5 inch form factor is always better, because you can place SSDs anywhere on the case, so you can improve the cooling conditions of SSDs.As for the faster drive, my favorite is:
Micron 9300 PRO 15.36TB, U.2 SSD
3500 MB/s (R/W)
€ 2579 (Xitra - Germany) for 15.36TB behemoth!
