SATA drives are nonetheless stylish, 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 additional PCIe slots.

The Samsung 870 EVO takes over the 860 EVO’s market place and is prone to be simply as profitable. We have examined the 1TB mannequin, however Samsung provides the next capacities: 250GB, 500GB, 1,000GB, 2,000GB, 4,000GB.

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

In 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.

Usually, the typical consumer does not need to be too involved about this. I’ve some previous SSD which are a few years previous, and they’re nonetheless wholesome regardless of being in use each day. That stated, it’s also potential to examine the well being of your drive utilizing a Samsung app. More on that later.

Larger SKUs ought to additionally get a bigger TurboWrite buffer, however I can’t fairly affirm it with out the 2TB or 4TB model readily available. Essentially, should you copy large recordsdata (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 superb job offering specs which are on-point and straightforward to confirm with benchmarks like CrystalDiskMark. Typically, 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. But in the true world, I’m far more within the random 4K numbers which are extra consultant of what’s occurring whenever you use the disk: the OS will manipulate a bunch of comparatively small recordsdata and blocks.

When it involves Random 4K operations, this drive outperforms some NVME drives, so regardless of SATA’s considerably decrease theoretical peak efficiency, the truth isn’t as unhealthy as one might imagine. That’s as a result of SSD drives not often carry out large sequential operations however as an alternative need to take care of a bunch of small recordsdata, just like the Operating System.

The Samsung 870 EVO pushes SATA to the restrict, and it’s arduous to think about how a possible 880 EVO SATA drive would possibly carry out. Today, the numbers we obtained from this drive are glorious (for a SATA drive) and most definitely the perfect you may get right this moment with this know-how.

The PCMark 10 storage check exhibits a extra practical image for many potential customers. With a PCMark 10 “Quick System Drive Benchmark” rating of 1492186.96MB/s (bandwidth) and 88µs (common entry time), the Samsung 870 EVO performs just a little bit higher than the 870 QVO, as a result of Samsung is aware of how you can section its product providing.

Beyond Performance

Speed apart, there are different elements to contemplate, 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 should you’re nervous about knowledge theft (laptop loss/theft, housebreaking), this or different types of disk-encryption is a necessary layer of safety.

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

The 5-year guarantee is fairly beneficiant, however as we stated earlier, keep watch over the TBW as properly should you write a number of knowledge.

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

With it, you may examine your drive’s well being standing, the encryption settings, handle numerous efficiency optimization settings, and even securely wipe knowledge. It’s nice for energy customers, however common people are usually not obligated to put in or use it.

Samsung additionally has a disk cloning utility referred to as Samsung Data Migration Software for Consumer SSD. It’s a dependable instrument that’s free and really useful when it’s a must to exchange your C: drive and clone the OS. Obviously, 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 section 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 opponents.


If you need the perfect of what the two.5-inch format and SATA interface provides, that is the product to get. People on the market are additionally purchasing for worth, during which case some options might be 10% to twenty% cheaper however technically inferior in numerous facets.

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

Overall product score: 9/10
