Samsung is increasing their line-up of SATA-based strong state drives, with a brand new collection of merchandise designed to steadiness efficiency and capability. A number of months again, the corporate launched the SSD 870 QVO collection of drives, primarily based on QLC, or quad-level cell, V-NAND. These new Samsung drives launching right now – the Samsung SSD 870 EVO collection – are related in lots of regards, however EVO SSDs function Samsung’s newest TLC (triple degree cell) V-NAND, with the commensurate firmware to match.
These new TLC-based drives additionally provide barely larger efficiency than their QLC-based predecessors, with longer warranties and higher endurance rankings as nicely. Check out the Samsung SSD 870 EVO collection’ full checklist of options of specs beneath, after which we’ll dig in a bit additional on the particulars and take a look at efficiency…
The Samsung SSD 870 EVO collection of drives are constructed across the firm’s newest 100+-layer, 3-bit per cell TLC (triple degree cell) V-NAND. That NAND is paired to a proprietary Samsung MKX controller and a few LPDDR4 DRAM cache. Particulars are scarce on the controller itself, however the quantity of DRAM put in on every drive is listed proper of their specs – there may be basically 1GB of DRAM per 1TB of drive capability.
The entire drives within the household, which can vary from 250GB on as much as 4TB, are rated for 560MB/s reads with 530MB/s writes, with 98K / 88K learn / write random IOPS, which is about as quick because the SATA interface can deal with. Endurance / TBW is class-leading with these drives as nicely. Samsung charges the 4TB mannequin at 2,400TB, or 600x the entire capability. And the entire drives carry a strong 5-year restricted guarantee.
Externally, Samsung continues with their conventional design aesthetic. The SSD870 EVO collection drives are the standard 2.5” 7mm kind issue (as you’d count on), with the highest aspect of the drives emblazoned with Samsung branding and a sole, coloured sq.. The underside is dwelling to a decal with the entire particulars, serial quantity data, and so forth.
Three pentalobe screws safe the enclosures collectively – one screw is seen and two reside below the decal. Disengage these screws and the enclosures pops proper open to disclose the PCBs inside; there is no such thing as a adhesive, thermal pads, or thermal interface materials to talk of in these designs.
What you see pictured listed below are the interior PCBs of the 1TB and 4TB Samsung SSD 870 EVOs. As you possibly can see, the PCBs are tiny, and fill solely a small portion of the two.5” enclosure. In whole, there are solely 4 chips contained in the 1TB drive – the controller, one piece of DRAM, a microcontroller of some kind, and a single piece of NAND, along with some floor mounted parts. The 4TB drive has a barely bigger PCB, with 4 items of NAND, two on the entrance, two on the again.
Like most previous-gen Samsung SSDs, the 870 EVOs use a portion of the NAND like a variable SLC write buffer. This enables the TLC NAND to carry out extra like an SLC drive for writes, giving write efficiency an total increase. With previous-gen Samsung drives, we might usually see efficiency drop off sooner or later when the buffer was exhausted, however each the 1TB and 4TB drives’ variable buffers are giant sufficient — and flush knowledge quick sufficient — to take care of peak efficiency throughout your entire capability. We also needs to point out that each drives assist Samsung’s newest knowledge migration instruments and Magician SSD utility as nicely, although the one factor included within the bins are the drives and a primary lit pack.
Samsung SSD 870 EVO Benchmarks
Underneath every take a look at situation, the SSDs examined right here had been put in as secondary volumes in our testbed, with a separate drive used for the OS and benchmark installations. Out testbed’s motherboard was up to date with the newest BIOS obtainable on the time of publication. The SSDs had been safe erased previous to testing (when relevant), and left clean with out partitions for some assessments, whereas others required them to be partitioned and formatted, as is the case with the ATTO, PCMark, and CrystalDiskMark assessments. Home windows firewall, computerized updates, and display screen savers had been all disabled earlier than testing and Home windows 10 Quiet Hours / Focus Help was enabled. In all take a look at runs, we rebooted the system, ensured all temp and prefetch knowledge was purged, waited a number of minutes for drive exercise to settle, and for the system to succeed in an idle state earlier than invoking a take a look at.

First up we have now SiSoft SANDRA, the the System ANalyzer, Diagnostic and Reporting Assistant for some fast assessments. Right here, we used the File System Bandwidth take a look at and supply the outcomes from our comparability SSDs. Learn and write efficiency metrics, together with the general drive rating, are detailed beneath.
The brand new Samsung SSD 870 EVO drives technically led the pack total, however we’re speaking about some miniscule efficiency deltas separating the entire Samsung drives right here. The Toshiba drive is a few share factors off the mark, however nonetheless aggressive nonetheless.
ATTO is one other “fast and soiled” sort of disk benchmark that measures switch speeds throughout a selected quantity size. It measures uncooked switch charges for each reads and writes and graphs them out in an simply interpreted chart. We selected .5KB via 64MB switch sizes and a queue depth of 4 over a complete max quantity size of 256MB. ATTO’s workloads are sequential in nature and measure uncooked bandwidth, relatively than I/O response time, entry latency, and so forth.
In ATTO’s learn and write bandwidth assessments, the brand new Samsung SSD 870 EVO drives competed on the high of the charts, throughout your entire curve. The drives stumble upon the boundaries of the legacy SATA interface, nevertheless, as anticipated.
There’s not a lot separating these SSDs by way of IOs both. Save for the previous-gen Samsung SSD 860 Professional and OCZ drives, which path barely with the smallest switch sizes, the entire Samsung drives as soon as once more carry out equally total.
Subsequent up we ran the Compression Benchmark built-into AS SSD, an SSD particular benchmark being developed by Alex Clever Software program. This take a look at is attention-grabbing as a result of it makes use of a mixture of compressible and non-compressible knowledge and outputs each Learn and Write throughput of the drive. We solely graphed a small fraction of the information (1% compressible, 50% compressible, and 100% compressible), however the development is consultant of the benchmark’s full outcomes.
The compressibility of the information being transferred throughout the drives has no influence on efficiency and the entire drives put up numbers inside a few megabytes per second. There’s solely a lot headroom a contemporary SATA SSD has to play with.
There isn’t any exceeding the boundaries of the interface on this take a look at however there’s nuance to the efficiency of those new Samsung SSDs, which you may see subsequent…
