Samsung 990 EVO review: great for the price, just don't expect true PCIe 5.0 speeds

TechRadar Verdict

The Samsung 990 EVO is a good SSD if you’re looking for a balance between performance, price, and efficiency, but it’s not quite as good at all of that as Samsung claims, making this a decent enough drive if you don’t need the true performance of PCIe 5.0 and you can get it for cheap.

Great random access performance

Doesn’t get that hot

Can fit in a PS5 comfortably

MSRP is highly questionable

Power efficiency isn’t as good as it should be

Samsung 990 EVO: Two-minute review

TheSamsung990 EVO steps into the spotlight following the well-receivedSamsung 990 Pro, setting the stage for an SSD to carry forward the EVO series' legacy of performance and reliability.

The 970 EVO Plus, this SSD’s predecessor, was one of thebest SSDpicks when it was released a couple of years back, and it’s still celebrated as one of thebest cheap SSDsyou can get even now, despite lacking the kinds of data rates you’ll get with a modern PCIe 5.0.

That leaves the 990 EVO with the ambitious task of following up a beloved budget model while introducing a hybrid PCIe 4.0/5.0 interface aimed at carving out a niche in an increasingly competitive SSD arena, and in that, it kind of succeeds - but also disappoints.

Right out the gate, the 990 EVO distinguishes itself with an interface capable of toggling between x4 PCIe 4.0 and x2 PCIe 5.0, which gives PC users a decent amount of wiggle room for their PCs if they’ve got a lot of drives plugged in. Coupled with a newly minted 5nm controller designed to enhance efficiency, the 990 EVO should be set up for success.

The drive opts for a DRAM-less configuration, however, that somewhat tempers expectations with its more modest bandwidth, leading to speeds that clock below what the best PCIe 4.0 drives are capable of.

Despite this, the single-sided 2TB variant I reviewed presents a versatile option for both PC enthusiasts and PlayStation 5 owners, a nod towards the growing standardization of high-capacity, single-sided drives. It lacks a heatsink, so PS5 users especially will want to look at an add-in heatsink just to be safe, but given the speeds involved, this drive doesn’t really get hot enough that you’ll need to be too concerned.

Targeted primarily at the laptops, OEM, and pre-built PC markets, the 990 EVO promises to deliver sufficient performance for gaming and everyday use, and positions itself as a compliment to the far more robust 990 Pro. It’s a more cost-effective solution for gamers and others while still benefiting from Samsung’s solid software support and reliability, and the option to toggle between PCIe 5.0 and PCIe 4.0 is a real value add for this drive.

Price-wise, the 990 EVO entered the market with a recommended retail price of $149.99 for the 1TB model and $239.99 for the 2TB variant, according to Samsung’s website, but even there, these prices have been marked down quite a bit, and you can find the 1TB model for about $90/£100/AU$219, depending on where you look.

This pricing strategy places it in a good balance with its Pro sibling and other competitors, especially in a market where SSD prices are on the rise.

Performance specifications for the 990 EVO boast up to 5,000 MB/s and 4,200 MB/s in sequential reads and writes, respectively, alongside impressive random read and write IOPS. These figures are complemented by a standard five-year warranty and support for TCG Opal 2.0 encryption, making it an attractive option for security-conscious laptop users.

In terms of real-world performance, I more or less achieved these speeds across the board, and the drive’s flexibility to operate across both PCIe 4.0 and 5.0 interfaces is a highlight. Despite the drive’s low-ish 5,000MB/s advertised sequential read speed (which doesn’t come close to maxing out the PCIe 4.0/5.0 lanes available to it), the drive does at least hit or exceed this claimed speed.

Despite these technical intricacies, the 990 EVO’s broader challenge lies in its identity within the highly competitive SSD market. It seeks to offer a balance between performance, efficiency, and price - a task complicated by the competitive pricing and superior performance of PCIe 4.0 alternatives like the 990 Pro,PNY XLR8 CS3140, orPatriot Viper VP4300.

All together then, the Samsung 990 EVO represents a solid addition to the SSD market. It doesn’t bring you the kind of PCIe 5.0 speeds we see with theCrucial T705, but it’s not meant for full-on performance. If you want that, you’ll be better off investing in a ‘real’ PCIe 5.0 SSD, but for what it is, the 990 EVO hits the mark it needs to hit.

Samsung 990 EVO: Price & availability

The Samsung 990 EVO starts at $149.99/£100/AU$219 for 1TB and maxes out at 2TB for $239.99/£169/AU$359, at least officially.

This doesn’t include a heatsink, but given the rather modest speeds and energy usage of this SSD, your motherboard’s heatsink will be more than enough since you really don’t even need the extra heat spreader for this drive.

While the above are retail prices for this SSD (according to Samsung’s website), even Samsung can be found offering these drives for up to 40% off, making this one of the best cheap SSD options out there if you’re hoping to find a good balance between price and performance.

Buy the Samsung 990 EVO if…

You want good performance for the priceThis isn’t the fastest PCIe 5.0 SSD, but for the price, its performance is great.

You need a laptop SSDThe biggest selling point of this SSD is that it’s geared more towards efficiency than high performance, so it’ll be good for laptops where battery life is a concern.

Don’t buy it if…

You want PCIe 5.0 speedsThe speed of this drive is ok for what it is, but don’t let the PCIe 5.0 interface fool you; you’re not even going to get max PCIe 4.0 speeds with this drive.

You just need any ol' SSDIf you’re just looking for an SSD for extra storage and you don’t actually care how fast it is, save your money and buy a cheaper SSD, maybe even theSamsung 970 EVO Plusor similar PCIe 3.0 drives.

How I tested the Samsung 990 EVO

I spent about two weeks testing the Samsung 990 EVO, using it as my primary system drive on my workstation PC that I used for content creation, general work use, and some light gaming.

Primarily, though, this drive is best reserved for mobile devices like laptops and possibly PC gaming handhelds that can better benefit from its improved energy efficiency.

I’ve been reviewing PC hardware for several years, in addition to earning my Master’s Degree in Computer Science in 2024, so I know very well how a drive like this should perform with its given architecture and price point — knowledge I leverage to ensure you find the best SSD for your needs and budget, whether it’s the Samsung 990 EVO or a competing drive.
