SATA drives are nonetheless fashionable, particularly when extending SSD secondary storage since many computer systems include (solely) one NVME SSD boot drive. Purists and SSD nerds would possibly frown on the thought of utilizing SATA, a legacy disk IO protocol, however the actuality is that it’s usually the one possibility for customers with a single m.2 and no further PCIe slots.

The Samsung 870 EVO takes over the 860 EVO’s market place and is prone to be simply as profitable. We’ve examined the 1TB mannequin, however Samsung affords the next capacities: 250GB, 500GB, 1,000GB, 2,000GB, four,000GB.

The performance is similar, however as the scale will increase, there are variations between completely different SKUs, primarily within the drive’s “Endurance,” expressed in Terabytes Written (TBW): information that may be written through the lifespan of the drive. The larger the drive and the upper that quantity might be, by an extra 250TBW per 250GB of storage.

On this occasion, the smallest 250GB SKU has a TBW of 150 TB (Terabytes), whereas the 4000GB one has a TBW of 1200 TB. TBW is a metric value as a result of the guarantee will often say one thing like ‘x’ Years or ‘y’ TBW.

Normally, the common consumer does not need to be too involved about this. I’ve some outdated SSD which can be a few years outdated, and they’re nonetheless wholesome regardless of being in use each day. That stated, additionally it is doable to test the well being of your drive utilizing a Samsung app. Extra on that later.

Bigger SKUs also needs to get a bigger TurboWrite buffer, however I can’t fairly verify it with out the 2TB or 4TB model readily available. Primarily, when you copy enormous information (tens of GB), TurboWrite will considerably speed up the write operations and preserve issues at close to most speeds till the buffer fills up. After that, the speed will lower.


SSD producers sometimes do a wonderful job offering specs which can be on-point and straightforward to confirm with benchmarks like CrystalDiskMark. Usually, the sequential learn and write outcomes will match the producer specs. That’s the case right here.

As anticipated, the disk’s SATA nature makes these sequential operations numbers a lot decrease than NVME fashions. However in the true world, I’m far more within the random 4K numbers which can be extra consultant of what’s occurring if you use the disk: the OS will manipulate a bunch of comparatively small information and blocks.

In terms of Random 4K operations, this drive outperforms some NVME drives, so regardless of SATA’s considerably decrease theoretical peak efficiency, the truth isn’t as dangerous as one might imagine. That’s as a result of SSD drives not often carry out huge sequential operations however as a substitute need to cope with a bunch of small information, just like the Working System.

The Samsung 870 EVO pushes SATA to the restrict, and it’s laborious to think about how a possible 880 EVO SATA drive would possibly carry out. At this time, the numbers we received from this drive are glorious (for a SATA drive) and almost certainly the perfect you will get at this time with this expertise.

The PCMark 10 storage take a look at exhibits a extra lifelike image for many potential customers. With a PCMark 10 “Fast System Drive Benchmark” rating of 1492186.96MB/s (bandwidth) and 88µs (common entry time), the Samsung 870 EVO performs a little bit bit higher than the 870 QVO, as a result of Samsung is aware of the way to phase its product providing.

Past Efficiency

Pace apart, there are different elements to think about, just like the AES-256 disk encryption, the 5-year guarantee, or the software program bundles.

I’m unsure how many individuals use AES-256 disk encryption, however when you’re fearful about information theft (laptop loss/theft, housebreaking), this or different types of disk-encryption is an important layer of safety.

Having on-disk encryption will carry out higher than utilizing software program options and be safer in some methods. Samsung isn’t the primary OEM to supply AES-256, however not all of them do.

The 5-year guarantee is fairly beneficiant, however as we stated earlier, control the TBW as properly when you write plenty of information.

The Samsung Magician SSD might be the perfect SSD software program suite I’ve seen typically and undoubtedly, the perfect one from an OEM.

With it, you possibly can test your drive’s well being standing, the encryption settings, handle numerous efficiency optimization settings, and even securely wipe information. It’s nice for energy customers, however common of us will not be obligated to put in or use it.

Samsung additionally has a disk cloning utility known as Samsung Information Migration Software program for Client SSD. It’s a dependable software that’s free and really useful when it’s a must to substitute your C: drive and clone the OS. Clearly, one of many drives must be a Samsung for this to function.

There are different options available on the market, however having a dependable and free possibility from the OEM is vastly handy and is undoubtedly serving to Samsung’s flash reminiscence enterprise.


The Samsung 870 EVO is a wonderful SATA SSD Drive that displaces the Samsung 860 EVO and just about cements Samsung’s dominance in that phase till one thing higher comes alongside.

We’d like to see extra competitors, however since Samsung controls the flash reminiscence, controller, and software program, it has the sting over many rivals.


If you need the perfect of what the two.5-inch format and SATA interface affords, that is the product to get. Individuals on the market are additionally searching for worth, by which case some options could be 10% to 20% cheaper however technically inferior in numerous elements.

It’s true that the 870 EVO barely outperforms the Samsung 870 QVO and Samsung 860 EVO but additionally comes with a value premium. The 1TB 870 EVO mannequin at present sells for ~$129.99, whereas the 1TB 860 EVO goes for $108.48, a close to 20% value differential. In any case, it’s laborious to flee from Samsung’s gravitational pull.

Total product score: 9/10
