AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.

AnandTech Storage Bench - Heavy (Data Rate)

The WD Blue is tied with the OCZ Trion 150 for average data rate on the Heavy test, where the SanDisk X400 had a substantial advantage that put it close to MLC drives.

AnandTech Storage Bench - Heavy (Latency)

As with The Destroyer, the WD Blue only has slightly higher average latency than the X400 and is not as slow as the Trion 150. Additionally, the average latency on a full drive beats competitors like the OCZ VX500 and Crucial MX300 that suffer disproportionately when their SLC caches are exhausted.

AnandTech Storage Bench - Heavy (Latency)

The number of high-latency outliers makes it obvious that the WD Blue is a TLC drive, but also makes it clear that the drive degrades gracefully under a heavier load rather than falling apart.

AnandTech Storage Bench - Heavy (Power)

The WD Blue is slightly more power efficient on the Heavy test than the X400, and both drives have better than average power consumption.

    it's an interesting drive, but why buy these when the likes of the mushkin reactor are $60 cheaper for the 1TB varient? sata III drives have peaked performance wise.

    OTOH, cant wait to see what the WD black SSDs look like. 4TB? M.2 PCIE?

    The Reactor 1TB was a clone of the BX100... which outperformed the WD Blue in a lot of tests here. Getting harder to find them though.

    Hopefully the street price of this will be more in-line with the rest of the market, price/performance wise.

    the only thing this WD drive does better is write endurance. 400TB, or even 320TB for the sandisk version, is a heck of a lot better then the 144TB of the 1TB reactor drive. Reply

    The thing I like most about this review is seeing how well my BX100 still holds up, and I paid the same MSRP this one is going for over a year ago. Reply

    I agree, I bought half a dozen BX100's when they went on sale. Excellent MLC SSDs. Reply

    It depends on the consistency of performance and not the peak

    The concern I have is Sandisk consistency of performance which cannot be checked using a single test drive

    I have 3 of the Sandisk Extreme Pro thumbdrives that are Windows to Go compatible as they are "Fixed Disks"

    One of them is completely unusable after a week, one is so-so and one is very good (performance wise)

    The only thing that will return the speed to "Like-New" condition is using Killdisk over the entire drive

    The CrapCleaner Drive wipe utility does not return full performance, and the new Defraggler SSD Optimizer does not return full performance

    I have not found any method other than Killdisk to temporarily regain full disk performance

    Of course, not having Trim or Garbage collection exacerbates the problem which then accelerates the thermal throttling issue

    Mushkin also has a bad rep for thermal issues on their Win2Go compatible thumbdrives

    The new Corsair GTX beats them all hands down for Windows to go and since my test machine is an older Sandy Bridge for XP compatability, the corsair is actually faster on the USB3 port than my Samsung 850 Pro is on the SATA2 ports

    I hope Anandtech can address consistency between identical drives at some point

    Corsair GTX Thumb drives seem VERY Consistent between drives as well Reply

    You seem to be a pretty unique case and not an average user in any way.
    But it's still an interesting comment I feel. Or I should say 'because of that' rather than 'still'.

    they can't build Black from air. sandisk best ssd is extreme pro, so Black will be updated version of it Reply

    Does this WD SSD come with software to clone/shrink your existing drive to the new SSD? I have an older SiliconEdge Blue 64GB SSD (still working well) and WD offers a utility on their website to do just that, but only if there is a WD drive attached to the machine. I assume this utility would work with this SSD? Not sure if you image your test drives using different tools or what.

    Samsung has another great utility that comes with a slick SATA-to-USB 3.0 dongle (free in the box) that will clone/shrink any drive to a target Samsung SSD. They go above and beyond the capabilities of Windows volume shrink by a lot.
