Test du Western Digital Blue SN5000
Sommaire
Design and packagingWD Blue SN5000 specificationsDecent performanceWestern Digital Blue SN5000: Reviews

The WD Blue SN5000 is the latest from Western Digital, offering a capacity of 4TB in the version sent to us. This SSD is, however, available in other storage capacities, and is intended, according to the manufacturer, for “creators and professionals”. At issue are the data rates, which aren’t the maximum that PCIe 4 can offer, but remain in themselves very decent for everyone.

Design and packaging

There’s not much to say about an SSD, it’s quite classic, a small card in M.2 format, smaller than a RAM bar. This Western Digital SN5000 doesn’t come with a heatsink; it’ll make do with the one on your motherboard, if you’ve got one.

In any case, almost all motherboards are now equipped with heatsinks, even the top-of-the-range ones, on all M.2 connectors. So there’s no point in having this kind of accessory on an SSD, except for some who prefer to remove those integrated on the board, and use the one on the SSD… If there is one.

The format is 2280, which could not be more classic, but it’s standard, so there’s no risk of making a mistake here. It fits all cards and even some laptops.

Decent performance

To measure the performance of this SSD, I used, as I always do, CrystalDiskMark and ATTO Disk Benchmark. The latter give a very reliable idea of the real throughput of internal or external storage media. Let’s start with CrystalDiskMark, which displays pretty decent data rates.

Data volume16 MB64 MB256 MB1 GB8 GB
Reading speed5494 MB/s5518 MB/s5528 MB/s5539 MB/s5543 Mb/s
Write speed5099 MB/s5086 MB/s4209 MB/s4206 MB/s3884 MB/s

In reading mode, it’s very good, with speeds slightly above what’s promised by the brand, as usual. However, when it comes to writing, I don’t get it. The more you increase the amount of data, and therefore the more you logically use the SSD, the more the speed decreases… Admittedly, 4,000 MB/s is still good, but it’s not the 5,000 MB/s promised by Western Digital, and the SN5000 isn’t showing its full potential here.

What we can see here, however, is that this SSD is sorely lacking in stability. Indeed, judging by the actual benchmark with ATTO, performance oscillates to a greater or lesser extent, especially when writing. While throughputs should be stable, it’s true that ATTO is stricter than CrystalDiskMark, but throughputs are not constant.

Western Digital Blue SN5000: Reviews

The Western Digital Blue SN5000 isn’t a bad SSD, but after a while, write speeds drop, which is frankly disappointing. Nevertheless, it’s still OK, nothing dramatic about that, but in terms of stability, it’s not extraordinary.

Résumé
Si vous cherchez un bon SSD PCIe 4 sans trop vous soucier des débits de ce dernier et de la stabilité, alors le Western Digital Blue SN5000 est fait pour vous. Il apporte un bon compromis dans son rapport performances / prix.
