Corsairs Raptor line of quality gaming peripherals has the features you need to win at a price you like click now to learn more welcome to my long overdue unboxing of one of the most important SSDs on the market this is the 840 Evo it is not the fastest SSD it's not the cheapest SSD but what it is is the complete package it's available in pretty much any capacity 120 250 500 750 and one terabyte they are all reasonably aggressively priced and because of some unique features that Samsung's implemented extremely competitive performance wise in spite of the very middle card wear specs so that's a bold claim Linus why would you say that and the answer will come later on in the video have to sit let me talk about other stuff so first up hardware specs they have shrunk the manufacturing process down to we think 19 nanometer but they're calling it 1x class nanometers which means that prices have come down versus the last generation product they are still using PLC NAND flash so that is three bit per cell mlc flash making the data densities higher than what other guys who are using two bit per cell LLC even in their entry-level drives are using but because Samsung has made some changes to their already excellent MDX controller so it's now the NEX three Core controller they are able to achieve great performance in spite of the inherently much slower write speeds that TLC flash has to work with so it's also got say 23.1 over sata3 on the last generation product and they've added hardware aes-256 encryption so that's basically there see there's a code on the back of this drive so that's basically a way to make it so someone's completely locked out of your drive unless they're willing to completely erase it so you can secure your data even from theft in the event that someone actually gets your drive and they can't even put it in anywhere else and unlock it so endurance is of course the big thing people talk about with PLC flash because not only does it write slower it also doesn't write as many times every SSD will die it actually has a rated number of writes that will eventually kill it now most SSDs will actually last much longer than that rate right speed and you can see they've done some extreme testing over on Xtreme systems go figure they do extreme testing there I just don't think it's that important even if it didn't last any longer than the rated number of right cycles you look at an excellent comparison by a non tech so that'll be linked in the video description huge a non tech fanboy over here if you guys didn't already know that they estimate that even with a very aggressive workload these drives which are the consumer grade drives are going to be lasting for years depending on the capacity now the larger the capacity of the drive the longer it's going to last to the point where you're looking at drives that are probably going to last for decades or die from some other reason rather than die from being written to too many times and it should also be noted that SSDs are much less likely to be damaged by shock or any other kind of physical you know demise that hard drives can meet because they don't have any moving parts now let's get into that bold claim that I made about why this drive which has TLC flash you know a faster clocked three core controller 400 megahertz versus 300 megahertz and you know otherwise isn't that special is the drive to beat and three things turbo right rapid and their new data migration to software so what turbo write is is a way of taking part of the storage on the drive and it varies according to the capacity of your particular drive it goes up as you have more capacity and takes part of that TLC flash and runs it in SLC mode so if you're not familiar with SLC that means only one bit per cell all right so that's even potentially faster than MLC back when that was the performance and long endurance what an NL C was the redheaded stepchild whereas now it's high-performance mlc and then plc as the one that is you know perceived as less reliable and slower so what that means is that when the drive gets written to it fills up that that SLC behaving cache first then distributes that data to the rest of the drive at its leisure that means that in real world terms the drive is faster unless you're doing a very long sustained write to it now reads are still fine on TLC flash so turbo write has pretty much no drawback in a day-to-day usage scenario which is very very cool you can enable it using samsung's SSD Magicians software it's very fast very low latency but it does rely again on non continuous use so again I'm in a non tech fanboy guys and you can check out their excellent article on turbo write which is linked in the video description as well next up is rapid which stands for fast no actually it stands for real time accelerated processing of i/o data and what rapid does is it allows you to take a gig of your DRAM so that is your system memory and use that to catch the SSD now this one I'm not quite sure if I feel as you know are completely positive about as I do about turbo right because it caches not only reads but also writes which means that if your system does lose power in the middle of it caching something into memory this is not the same as caching to SLC flash which is still going to be there when the system reboots and the power goes down memory is cleared when the power goes out so it can cause data corruption but if you're running on a laptop or anything else that has a battery backup such as a desktop with a UPS and your system is very stable I wouldn't worry about it too too much so what it does is it takes up to a gig of your system memory and allows it to operate many times faster than even the fastest SSD can because it is effectively reading and writing out of RAM it's not the same as a ram disk implementation because it's all completely uh it's all completely automated unlike Ram disk software which often requires a lot of manual intervention the next one up is data migration to so what that allows you to do is say ok well I bought this new SSD but I could only afford a 250 gig SSD and quite frankly the hard drive that I bought like four years ago is already 500 gigs and I've got all this data on it what am I supposed to do if I migrate it over what am I videos and photos and songs just lost in the ether of the answer is no what data migration to does is it allows you to specify two targets so you can clone your OS and all the important programs and stuff over to an SSD and then you can have a secondary hard drive that all your data goes to so it's actually painless enough to use that even my mother can do it so we're going to do a follow-up video on rapid the data migration to software as well as turbo right that's going to be hosted by slick but basically without even watching that all you need to know is this drive just pretty much rocks thank you for checking out my unboxing an overview of the Samsung 840 Evo don't forget to like this video if you liked it dislike it if you dislike it leave a comment if you have something to say to me how much did Samsung pay you to make this video believe it or not sometimes I just like stuff I'm allowed to do that and as all these guys don't forget to subscribe
