AnandTech Storage Bench - The Destroyer

The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.

We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.

AnandTech Storage Bench - The Destroyer (Data Rate)

The WD Blue fails to keep up with the competition on The Destroyer, trailing behind everything except the Crucial BX200. Where the SanDisk X400 was one of the fastest TLC SSDs, the WD Blue is merely acceptable.

AnandTech Storage Bench - The Destroyer (Latency)

The average service time of the WD Blue is only slightly worse than the SanDisk X400, and still clearly better than the OCZ Trion 150. This suggests that the WD Blue's lower average data rate is due to it being uniformly a bit slower, and that it isn't experiencing any severe stalling.

The WD Blue does not suffer from any more high-latency outliers than other TLC drives at the 100ms threshold, but at the 10ms threshold it is worse than average where the X400 exceeded expectations.

AnandTech Storage Bench - The Destroyer (Power)

The WD Blue thankfully shows no regression in power efficiency and falls in the second tier of drives with energy usage, on par with the SanDisk X400.

    That's funny you should say that since I've been noticing it for years. Every single time I move around large files to reorganize or back them up, in fact. But I'm sure that I'm the only non-video editing person on the planet who doesn't use his computer exclusively for reading and writing tiny text files and browsing the internet. I'm also sure that I'm the only who would have a problem paying a premium for very low capacity devices just so I could experience their limitations.

    Oy vey, nobody in the market cares for my special snowflake wants, it`s anudda shoah!

    You need more explosions in your posts. ;D

    It's cheap but not really excitingly cheap. Doesn't really beat the aged MX200 which also comes with MLC NAND which I deem superior to this TLC low-end crap. Only advantage this has over MX200 is price. Good for a cheapo game-drive maybe but would avoid as OS drive.

    Ewww, 15nm planar TLC along with WD branding.

    I remember the time when the 850 Evo was considered a "budget" SSD. Now it's almost a high-end SSD.

    And the price of evo is still going up. Hopefully there will be stop to it eventually.

    It's not really going up, just plateau'ing hard, sales might be happening slightly less frequently lately, I dunno... I do remember seeing the 1TB under $300 a number of times but it's mostly been just over $300 for well over a year.

    I paid $320-ish for two back in July-August 2015 when they were first starting to get close to $300. It's still faster than the field and brand alone is probably sustaining their ability to charge a premium.

    Maybe it depends on where you live, but the 850 EVO went up a lot where I am (UK). Back in Jan this year the 250GB was 53 UKP, now the same model is 85 UKP. Samsung is exploiting demand for what used to be a well priced, reliable product to give the model a premium image that's pushing its cost far above where it really should be. This has happened before, eg. when the 830 series shot up in early 2013 after strong demand, which helped ensure all other brands didn't lower their prices.

    what HASNT shot up in price in the UK post-Brexit vote?
