The Samsung 960 Evo and 960 Pro NVMe SSDs really feel like they’ve been round for an absolute age, however once I heard they have been getting changed earlier within the week by a new 970 series as of May 7, it nonetheless got here as one thing of a shock. These new NVMe fashions are additionally cut up into Pro and Evo variants, and immediately I’ve received the 1TB model of the 970 Evo. Let’s see the way it lives as much as its Best SSD-crowned predecessor.
Available in 4 sizes beginning at 250GB all the best way as much as 2TB, the 970 Evo is already an enormous enchancment over its 960 predecessor earlier than you even take it out of the field. For starters, you get a five-year guarantee as an alternative of three, and its endurance ranking has been raised exponentially throughout each capability, providing between 150 terabytes written (TBW) on the 250GB mannequin and an enormous 1200TBW on the 2TB one. Compare that with the 960 Evo’s endurance vary of 100-400TBW throughout 250GB-1TB and that’s much more reassuring for immediately’s would-be NVMe patrons.
That stated, Samsung’s 970 Evo isn’t the one one to supply this sort of peace of thoughts. Western Digital’s upcoming Black 3D NVMe SSD, as an illustration, really goes a smidge additional than Samsung’s newest, as this additionally comes with a five-year guarantee and an endurance ranking starting from 200TBW for the entry-level 250GB model (that’s 50TB greater than the 250GB 970 Evo) as much as 600TBW for the 1TB mannequin (the identical because the 1TB 970 Evo).
WD’s claimed sequential learn and write speeds additionally go toe-to-toe with the 970 Evo, maxing out at 3400MB/s learn and 2800MB/s write for its prime 1TB mannequin. The prime 2TB 970 Evo, by comparability, is rated for 3500MB/s sequential learn and 2500MB/s sequential write (though the previous drops to 3400MB/s if you go for the 1TB mannequin on take a look at right here).

The race is even tighter within the 250GB and 500GB capacities as properly, with Samsung providing 3400MB/s sequential learn for each sizes, beating WD’s 250GB Black 3D mannequin and matching its 500GB measurement, however solely respective sequential write speeds of 1500MB/s and 2300MB/s, which WD bests with 1600MB/s and 2500MB/s. Here’s a graph to make all {that a} bit clearer:
| Samsung 970 Evo | WD Black 3D NVMe SSD | |
| 250GB | 3400MB/s learn, 1500MB/s write | 3000MB/s learn, 1600MB/s write |
| 500GB | 3400MB/s learn, 2300MB/s write | 3400MB/s learn, 2500MB/s write |
| 1TB | 3400MB/s learn, 2500MB/s write | 3400MB/s learn, 2800MB/s write |
| 2TB | 3500MB/s learn, 2500MB/s write | N/A |
I haven’t examined WD’s Black 3D NVMe SSD within the flesh but (I’ll replace this overview with a extra detailed comparability as soon as I’ve), so it’s exhausting to say precisely the way it stacks as much as the 970 Evo in follow. Still, it’s value conserving in thoughts instead for those who occur to search out one cheaper than the opposite as soon as costs calm down post-launch.
Whatever you find yourself going for, although, the Samsung 970 Evo definitely gained’t disappoint. Daily efficiency was completely distinctive, with each process seemingly taking place at lightning-fast speeds that I couldn’t probably hope to measure by stop-watch alone.
To assist get a extra concrete measure of its efficiency, I turned to the artificial AS SSD benchmark. Here, it produced a blistering sequential learn velocity of 2954MB/s and a sequential write velocity of slightly below 2400MB/s. That’s a bit decrease than quoted, however contemplating the identical take a look at PC (a 3.6GHz Intel Core i5-8600Okay processor, 16GB of Corsair Vengeance 3000MHz RAM and an Asus Prime Z370-P motherboard) solely received round 2500MB/s and 2000MB/s out of the 960 Evo – which is quoted for 3200MB/s sequential learn and 1900MB/s sequential write – that’s nonetheless a big enchancment over the earlier mannequin.
At least it’s for those who’re studying and writing blocks of information sitting subsequent to one another, which isn’t actually that indicative of how SSDs work in actual life. Instead, they normally retailer all the things higgledy-piggledy, making Random checks a way more correct means of determining how briskly they’ll be day-to-day.
In AS SSD’s Random 4K take a look at, for instance, which reads and writes 1GB’s value of information in tiny 4K chunks all around the SSD, the 970 Evo managed a good 56MB/s learn velocity and 170MB/s write. That’s a 20% sooner learn velocity and a 15% sooner write velocity than the 960 Evo.
Not an enormous margin, you may say, however if you examine it what a 2.5in SATA3 SSD is able to – let’s take Samsung’s own 860 Evo for example, which has additionally been illustrated within the graph above – the distinction between every kind issue begins to turn out to be much more apparent, the 970 Evo racing forward of the 860 Evo by 28% in studying and an enormous 42% in writing.
The 970 Evo is eminently a lot better geared up to cope with workstation-level workloads as properly, as its large results of 2035MB/s learn and 2039MB/s write in CrystalDiskMark’s Random 4K 8-queue-8-thread take a look at comfortably proves. By comparability, not even Samsung’s 960 Pro managed to go above 1700MB/s learn and 1450MB/s write on this take a look at, which simply goes to indicate how way more highly effective and extra environment friendly Samsung’s new Phoenix controller is over the 960’s Polaris chip.
As I stated, all that is exhausting to quantify with out equal outcomes for the WD Black 3D NVMe SSD, however one factor is obvious. The 970 Evo is a big leap from each its predecessor and Samsung’s top-end 960 Pro, making it one of many best-value NVMe drives the corporate have ever produced and definitely one of many quickest and best SSDs you may presently purchase full-stop.
Even higher, costs begin from simply £100 / $120 for the 250GB mannequin, which is a fraction cheaper than WD’s proposed Black 3D NVMe SSD pricing of £110 within the UK and exactly the same as it’s within the US. If you’re after an NVMe with mad speeds and is definitely vaguely inexpensive (sure, I’m taking a look at you, 512GB 970 Pro that prices £275 / $330), the 970 Evo is a superb decide.
