    At this moment I C: run both desktop and laptop from Samsungs 1Tb SSD.

    But on the laptop at least I'm thinking of moving up to a 2Tb SSD.

    Prices are reasonable and it would allow me more free space on that disk, which now averages less than 20%.

    The brands and models I'm considering are the SAMSUNG 860 EVO 2TB and the WD Blue 3D NAND 2TB.

    My concern now is about some comments I have found compalining that Samsung got less strict in product quality or even fake units around with much worst specs.

    So first: what about those models I listed?

    And second: are SSDs getting worst?

    Buy from verified sellers. If the price looks too good to be true, then it is. No, SSDs are not getting worse. You'll find both bad and good reviews from every manufacturer on the planet. If you are worried about loosing data, get a backup drive.

    QLC drives may have lower performance than TLC.

    I would trust Samsung SSDs over any other brand.

    Which is which?

    Amazon can be considered a verified reseller?

    The WD Blue 3D is TLC.

    Depending on which version of the Samsung you get, it's TLC also. The EVO is TLC, but I think they have a new one coming out EVO-Q or something which is QLC (I don't remember the exact name of it as it was maybe a month ago I read an article about it).

    QLC is not exactly an improvement in the SSD area. Only price_per_GB-wise but at the moment this is disputable, at least for Samsung.
    QLC can sustain as low as 80MB/s write for lower-capacity models which is about 3 times worse than TLC. The cache helps some but...
    While TLC was still Ok and acceptable compared to MLC, now QLC would be all but compelling to me and most people willing to fit one as their boot or working drive.

    How can I know which are MLC? It's not mentioned on most specs.

    Samsung Pro models use MLC.

    If its not mentioned it likely is not MLC.

    Thanks. At the moment I'm undecided between those Samsung and WD models.

    Any of them would be the C: on my laptop, and I think they are reliable and fast enough to be so.

    Still, Samsung has an edge in my SSD list over all others if prices is not a factor or are close enough.

    Thanks, I will probably pick the Samsung.

    I also only use Samsung SSDs personally, although we've been testing some cheap PNY SATA SSDs at the office lately and haven't run into any issues. WD drives are probably fine given that I haven't seen any negative reports or reviews about their models, but since the tech was originally Sandisk it gives me pause after having 3 out of 4 Sandisk SSDs I've used die without warning.

    I've had SSD's from all sorts of brands. The only one that gave me trouble was OCZ Vector 2s.

    My first SSD was one of those, a 120GB Vertex2. When it died it was fascinating since it didn't go right away. The first thing I noticed is that the network adapter stopped working, then the Windows Control Panel started losing icons and C:\Windows\System32 files disappeared gradually in real-time. I RMA'd it right before OCZ got bought by Toshiba, and sold the replacement with the caveat that the Vertex3 they sent me was a RMA unit and probably not any more reliable than the 2 that killed itself. IIRC OCZ used absolute garbage-tier flash in those things that no other vendor would touch.

    Same. I am an aerial surveyor, and my equipment collects vast amounts of data that is initially stored on SATA SSDs.

    I've tried many brands, and only ever had problems with OCZ and Intel ones.

    In the case of OCZ, I had one that wore out after just a few full cycles. It still sorta works, but is pretty flaky, and can't write anywhere near fast enough to be useful for surveying. In the case of the Intel ones, I eventually wore them out after filling them up and wiping them hundreds of times. They still work, but again, can't write fast enough to be usable in my LIDAR scanner. I think we got our money's worth out of the Intel ones, but I wouldn't trust the OCZ ones with data I couldn't replace.

    I like the Samsung 860 Pros the best. I have several that I've used the hell out of, and they don't seem to degrade. Corsair's higher end ones used to be pretty good too, but it's been a couple of years since I got any new ones of those. I suspect they're mostly Samsung inside anyway, though.

    Same with sandisk failing (1 dead after 20 seconds formatted other 2 failed the same after 6 months and went into half read only mode witch was lucky as most ssds typically fail dead)

    WD might not be using the same model sandisk that failed (think it was sandisk ultra plus)

    You mean that WD bought Sandisk and/or is using their SSD technology?

    WD bought SanDisk. I doubt they're still using the same controllers, or at least not with a ton of extra validation.

    Well, now the question is if it's worth it pay about twice the money in an MLC Samsung, intead of a TLC one.

    Probably not, unless you have some specific workload that merits the higher endurance, and/or maybe if you're expecting to consistently be doing large transfers where MLC often is better able to keep up once the cache fills (fun fact I never noticed before: for a given capacity the 2.5" version of the 860 Evo has more cache than the m.2/mSATA versions). Transfer rates and IOPS between the two are close enough to not be a factor.

    But it's probably a moot question unless you have a larger or older laptop that accepts 2.5" drives. The 860 Pro isn't available in m.2 (or mSATA FWIW).

    And don't be fooled by the spec sheets listing the 860 Evo as 3-bit MLC. That's just some way to weasel around calling it TLC.

    I didn't know more recent laptops didn't accept 2.5" drives anymore. I do not like that m2 format.

    As I live by the sea, all air-exposed circuits might oxidate. It happened on some of my 3.5" drives. The SSD being encased is a very good thing, I think.

    Let's hope the M2 doesn't become the standard for SSDs.

    One very good thing about my Asus GA-Z97X mobo is that the parts are all painted and protected from air-contact.

    M.2 is going to be more common as everyone wants thinner laptops. As long as they're using NVME or mSATA this doesn't really cause any issues, except for mSATA being more expensive than 2.5" drives currently. I needed to buy a mSATA 860 EVO for my laptop in November as it doesn't have a 2.5" slot, and it was about the same price as my 970 EVO for the desktop (maybe 30% more expensive than the 2.5" model at the time). SSD prices are expected to drop further this year at least.

    Too late, at least for desktop/laptop systems. It's pretty much mostly m.2 going forward, especially as laptops get thinner, and NVMe becomes more prevalent as u.2 (and that abomination SATA express) never took hold in the consumer space.

    But an m.2 card is no more exposed than the mainboard it's attached to. Shouldn't be an issue.

    I was surprised to see the 860 Pro isn't available in m.2 (guess Samsung sees no market for it).
