Review Lexar NM620 – 2021

Lexar NM620 (12.9999 list tested for testing 12GB version), a midrange Internal M.2 SSD, Has a faster text / write speed than Lexar NM610, Which we reviewed a year ago. Like its predecessor, it performed well in the execution of our benchmark test, in this case returning to a high KK read and write score. Although it is a founder among others, it has a low durability rating for TLC-based drives, and is of little value for what it provides. For most upgraders, this is enough for daily use, but discriminating power users only want to scout this drive at a discounted fee, on a per-gigabyte basis.


Mainstream TLC, Plus PCIe three

— Level Triple-Level-Cell (TLC) based on NAND Flash, employs Lexar NM620 NVMe protocol Four-lane PCI Express (PCIe) 3.0.0 on the bus and features integrated controller. (Check Our SSD Disintegrator To make sense of those terms and acronyms.) The drive is built into one M.2 Type – 228080 (mm0 mm long) “Gumstick” format, usually seen on internal SSDs.

The drive comes in three capacities: 266 GB, 1212 GB, and 1 TB. (Only the last two are available in the US at the time of writing.) Lexar supports the NM620 with a five-year warranty, which is a good incentive from the NM610’s three-year coverage. The company doesn’t offer any storage-management or encryption software for drives, so if you want them, you’ll need to use a third-party offer.

The durability ratings of the NM2020, measured in terabytes (TBW), match the matches we’ve seen with the Lexar NM1010, and we’re lower than we would expect from a TLC-based drive. (TLC-based WD blue SN550 Durability ratings that are around – 300TBW less for the GB00 GB version, and T00TBW for 1TB – but it sells for less than the NM620.) Ratings we often see with drives based on less durable QLC memory. For example, the editor’s choice wins Intel SSD 670p, A QLC-based drive, priced at just 1 185TTBW 512GB and 0 370 TBW for its 1TB model.

There are plenty of PCI Express 3.0.0 x 4 drives on the market, but the Lexar NM620 is no big deal, either. At the 1212GB capacity we tested, the drive costs 1 gift per gigabyte, and the 1TB version runs at 1g cents per gigabyte. This is more than just an editor’s choice Samsung SSD 8080, Which goes for 1 14 cents per gig for its GB00 GB version and 1 cc per gig for the 1TB model, and bigger than the Todd. Intel SSD 670p, Which runs at 1 gift per gigabyte for its 1212 GB model and 1 GB per 1 gift per gigabyte. The price-oriented WD Blue SN550 runs at 13 cents per gig for the 100GB and 10 cents per gigabyte for the 1TB version.

Checking the Lexar NM620: Mixed bag of scores

We test all our Serial ATA (SATA) and PCI Express SS.0 SSDs in PC Lab’s main storage testbed, which is built on Asus Prime X299 Deluxe motherboard. Intel Core i9-10980XE Extreme Edition C.P. U.S. We use 1MB of DDR4 Corsair Dominator ROM at 3, 3,00 MHz, and the system employs Nvidia GeForce RTX 2080 Ti Founder Edition As its inactive graphics card. (See more about how we check SSDs.) PCIe SS.0 SSDs are tested with a different, AMD Ryzen-based testbed with .0 support.

PCMark 10 composite storage and trace-based tests

The overall PCMark 10 storage test, from UL – the world’s leading independent benchmark developer, runs a full suite of specific drive-access functions. Below represents the overall storage test scores on how a good drive makes the entire PCMark 10 runs. This is the accepted score presented by UL Software at the end of each run.

Then we get some more granular measures extracted from the background “traces” of PCCark 10. The following PCmark 10-derived tests represent simulations of how quickly a drive is able to launch a particular program (or, in the first case, Bootz Windows 10). Windows 10 Trace simulates the full Windows 10 operating system startup process and how quickly the drive records the type of data requested.

Then there is a game start test set, which simulates how fast the drive can read shallow depth small random KK packages, one of the more commonly used file-block sizes for game installations. As far as file block size depends on the title you’re playing, 4K small random reading is the most accurate block-size metric relevant to these three popular FPS titles: Battlefield, Overwatch, and Call of Duty: Black Ops 4.

Drives are also put through critical testing for creative types. Anyone who regularly works on programs like Adobe Premiere or Photoshop can tell you that a fixed pinch point is the time it takes for these programs to get started.

Finally, PCMark 10 copy tests are also taken from the PCMark 10 trace. Initially, these numbers may appear lower when compared to direct sequential-throughput numbers on benchmarks such as Crystal Diskmark.0.0 and AS-SSD, which are charted below the PCMark 10 results. But the reason for this is the way the score is calculated and the nature of the source data set (and the difference between the two).

The NM620 turned into a Middling Score in PCMark 10 overall storage test, with some good four-lane PCI Express 3.0.0 drives like the Samsung SSD 80 90, Intel SSD 707070 p, WD Blue SN550, and Important P5 Circular cross Its PCMark 10 trace score was not impressive; For one, it had a low score in the game start test for Call of Duty: Black Ops 4.

Sequential testing and copy testing

Moving on from PCMark 10 derivative numbers, Crystal Diskmark .0.0 Sequential tests simulate best-case, straight-line transfers to large files. The SSD benchmarking utility is then a series of file and folder transfers performed on the AS-SSD. This trio of tests includes copies of large files or folders from one location to another in the test drive.

For the 512GB version of the NM620, Lexar’s rated read / write speeds are 3, 300 MBps read and 2,400 MBps write. The Crystal Diskmark .0.0 Sequential Speed ​​Benchmark was closely tested while reading 3, 155MBps and writing a score of 2,3877 Mbps.

Crystal Diskmark’s KK (or “Random Read / Write”) mimics specific processes involved in test programs / game loads or bootup sequences. The KK reading test was a benchmark in which the Lexar NM610 excelled when we tested it last year, compared to the drives we compared. NM620 script overturned, converted to high score in 4K Write When posting the average part 4K reading score, part of the test – just losing so many other drives by doing so. The NM620 also scored high in the AS-SSD game-folder copy test, and did very well in the AS-SSD’s ISO-image-file copy-speed test.


Only one incremental upgrade

The Lexar NM620 internal SSD represents an improvement with its predecessor, faster sequence read-write speed than the NM610 and a longer warranty. The NM620 was inconsistent in our tests, showing brilliance by using crystal discmark 4K writing and some AS-SSD copy tests, but PCmark 10 proved unaffected in the test and turned out to be the lowest score in a game start test.

Lexar NM620

The drive is a little valuable for what it offers and has a low durability rating for a TLC-based SSD, but it should be fine for general-purpose use. For both the display and the value on a PCI Express internal.0 internal SSD, our top pickup is still the Samsung SS SSD 980.
