There’s a tough pace restrict imposed upon the hoary ol’ SATA connection… 600MB/s and no additional. That’s as quick as the newest iteration of the storage interface can go; if you need sooner you then’ve bought to modify to PCIe-connected NVMe drives. For Samsung’s new 860 collection SSDs, then, storage is just not in regards to the dash, for SATA drives it’s now all about marathon endurance.
Your SSD alternative is essential however for total system efficiency that you must ensure you have the best CPU for gaming.
This is the troublesome messaging producers of SATA SSDs are having to deal with proper now. Because of the widely excessive price of reminiscence the capability, and value per GB, of SATA drives hasn’t actually modified over the previous few years. The pace isn’t going to interrupt free from the shackles of the SATA 6Gbps interface, so everyone seems to be having to start out buying and selling on one thing apart from tempo and capaciousness.
To that finish Samsung are chasing down drive endurance figures because the go-to stat for evaluating SATA-based SSDs, now that pace is being extra capably handled by superfast NVMe drives.

Samsung 860 EVO specs
The new 860 EVO SSD is the distillation of all of the strong state learnings Samsung have achieved over the previous few generations of each SATA and NVMe-based drive. It’s utilizing the identical vertically stacked NAND flash reminiscence because the lightning-quick Samsung 960 EVO: their very own in-house designed and manufactured 256Gb Three-bit MLC V-NAND. At least it’s for the 250GB and 500GB variations of the drive. From what I could make out the upper capability variants – the 1TB, 2TB, and 4TB drives – are all utilizing bigger 512Gb reminiscence modules.
Yeah, 4TB. Four terabytes. Terrifically massive SSD, that.
Having the smaller 256Gb (32GB) modules within the 250GB and 500GB SSDs means larger parallelism when working with the brand new Samsung MJX reminiscence controller. If they have been utilizing the 512Gb (64GB) modules at that capability you’d have fewer dies feeding into the a number of reminiscence channels of the controller, and subsequently decrease efficiency.
The Three-bit multi-layer cell (MLC) V-NAND – additionally recognized by the catch-all time period, triple-level cell (TLC) – is essentially the most cost-effective of the totally different SSD reminiscences getting used proper now. It has a decrease endurance ranking than customary 2-bit MLC, a bit decrease total efficiency, and in addition a barely greater energy draw. That’s why you’ll discover the TLC V-NAND being utilized in Samsung’s EVO drives whereas they stick to conventional MLC for his or her PRO SSDs.
We’re anticipating to see quad-level cell (QLC) NAND arriving this yr because of the vertically stacked designs. It’s more likely to be slower and with decrease endurance than TLC, however might enable 500GB class SSDs to hit the magic $100 mark. The QLC NAND will enable the flash reminiscence to retailer 4 bits per reminiscence cell, so count on Samsung to be calling it Four-bit MLC…
Despite the decrease stage of endurance from the 860 EVO’s TLC reminiscence Samsung are nonetheless providing a good 5 yr guarantee on their lower-spec drives. The massive information, nevertheless, is that they’ve massively upped the sport relating to the whole bytes written (TBW) figures for the EVO vary. With the last-gen Samsung 850 EVO the 500GB drive has a assured rated endurance of 150TB to be written over its lifetime. Samsung have doubled that with the 860 EVO, pushing as much as 300TB.
That equates to a reasonably darned hefty 164GB being written to it every day for 5 years.
Samsung are claiming there’s no secret sauce being baked into their new drives, that there’s nothing apart from their confidence and experience within the manufacturing of all of the totally different components of their SSDs going into doubling the anticipated endurance of their 860 vary. That alone is somewhat spectacular.
Being in a position to reduce down the quantity of energy the 860 EVO attracts compared with the earlier generations of Samsung SATA drive goes to have one thing to do with that elevated longevity. The new 860 EVO 500GB attracts a median of two.5W when hitting its learn/write peaks, whereas the 850 and 840 EVO SSDs of the identical capability draw round 4W. That’s almost double the effectivity.
As properly as utilizing the identical reminiscence as their 960 EVO drives the 860 EVO is implementing the identical Intelligent TurboWrite algorithms that gave the PCIe-based 960 EVO the flexibility to maintain tempo with its Samsung 960 PRO variant. TurboWrite permits the drive to apportion a few of its storage as single-level cell (SLC) reminiscence – basically letting it act as a speedy write buffer. This has been round because the 840 EVO period, however with the 960 EVO Samsung gave the function the flexibility so as to add to its default TurboWrite capability if the write operation was going to exceed the usual quantity of cache out there to it, thus slowing down the method.
The Intelligent TurboWrite function provides the 500GB 860 EVO a 4GB default buffer, however lets it take an extra 18GB from the spare capability of the drive. Obviously the SSD must have at the least this quantity of free area out there to have the ability to make the most of the dynamic caching system.
Samsung 860 EVO benchmarks
Samsung 860 EVO efficiency
The 860 EVO performs precisely the way you’d count on a contemporary SATA-based SSD would. Which is to say that it’s knocking across the 500MB/s stage when it comes to its sequential read-write efficiency. Given the exhausting 600MB/s limitations of the SATA interface that’s the identical kind of efficiency we’ve been seeing from these little SSDs for at the least the final 4 years.
That’s to not say the 860 EVO isn’t one of many quickest SATA SSDs you should purchase proper now, it completely is. Even in contrast with the PRO model, the 860 EVO is up across the high with each the ATTO peak learn/write and AS SSD exams. That stated, whereas the drive is a succesful performer, it’s not precisely massively sooner than the final era of SATA SSDs or, crucially, the current Crucial competitors.
The PCMark8 SSD consistency take a look at highlights the distinction between this era of Samsung drives and the earlier variations of the EVO. The consistency take a look at hammers the SSD with an enormous quantity of knowledge – measuring its efficiency because it does – after which permits it to recuperate on the finish, exhibiting the distinction in pace when it’s extra flippantly used. You can see that even when it’s being thrashed it presents greater than twice the throughput of the 840 and 850 EVO SSDs.
But, as I stated originally, SATA SSDs are not about efficiency. If you need pace you pay the massive NVMe bucks, however if you need longevity out of your SSD information storage then that is the place it’s at for strong state drives.
This 500GB 860 EVO has an endurance ranking that’s 100TB greater than the pricier 500GB 960 EVO, although it has an additional two years in contrast with the 960’s guarantee. That interprets over to the PRO comparisons as properly, the place the 860 PRO has one other 200TB over the 960 PRO’s whole bytes written ranking, regardless of each having the identical 5 yr guarantee.
Samsung 860 EVO verdict
It’s robust to argue towards the Samsung 860 EVO now being the go-to SATA SSD available on the market. The 32p/GB price ticket of this 500GB drive means it isn’t the best-value SSD you’ll choose up right now, however given it’s sporting an unprecedented stage of endurance the 860 EVO would make both a decently speedy, comparatively reasonably priced boot drive, or an impressively fast, capacious, long-lasting information/scratch drive.
Where you can argue towards it, nevertheless, is once you have a look at the extent of efficiency you may get out of the brand new Crucial MX500. The Crucial drives have typically been the one cloud on Samsung’s SSD horizon, because of the actual fact mum or dad firm Micron could make each the 3D NAND and the DRAM cache for Crucial’s SSDs, however they’ve latterly dropped off the tempo in favour of purely being the worth proposition.
The MX500 won’t have the assured endurance of the 860 EVO, nevertheless it’s bought just about the identical stage of efficiency, and also you’d actually need to go some to get by the 99GB written per day stage the 180TB TBW figures counsel from inside its 5 yr guarantee. And Crucial are nonetheless in a position to undercut Samsung regardless of having to go exterior the corporate for its Silicon Motion reminiscence controller.
But that’s the place Samsung’s power on this market actually lies, they will create SSDs purely from their very own , whether or not that’s NAND, DRAM, or reminiscence controller. That permits them to be aggressive on value, but additionally provides them the arrogance to ensure this stage of endurance.
What doesn’t fairly make sense, nevertheless, is why they’re nonetheless persisting with the PRO and EVO class drives for SATA. Because it’s utilizing the sooner, extra dependable MLC V-NAND the PRO can supply greater efficiency and a better TBW ranking, however you’d actually need to go some to high the 300TB TBW stage wanted to justify the 860 Pro’s 600TB ranking. If it retained the ten yr guarantee then perhaps the pro-user could be higher off with the eponymous 860 PRO, however as Samsung have halved the intense drive’s guarantee it makes much less and fewer sense.
While SATA SSDs at the moment are largely all about area, not pace, Samsung are clearly hoping that banging the endurance drum (very tiring, that) may have individuals queuing up for the 860 EVO. And they in all probability ought to, it’s a wonderful drive. The drawback is that I’d fortunately take that hit on the endurance aspect to avoid wasting a piece of money, realizing the Crucial MX500 is greater than sufficient SSD for many of us avid gamers.
