SanDisk X210 256 And 512 GB: Enthusiast Speed; OEM Reliability

Results: Power Consumption

Idle Power Consumption

Active idle power numbers are critical, especially when it comes to their impact on mobile platforms. Idle means different things on different systems, though. Pretty much every drive we're testing is capable of one or more low-power states, up to and including DevSleep, a part of the SATA 3.2 host specification. And although DevSleep requires a capable SSD and a compatible platform, enabling it takes power consumption down to a tiny figure. This is why we test active idle; it's easy to identify, and is still where SSDs spend most of their time.

The X210 fares well in this metric partly as a result of its Marvell 88SS9187 controller. Registering 0.47 W, both SSD valiantly charge at the most power-friendly drives in our comparison, even if they fall a bit short. But given the environments these SSDs will drop into, one-tenth of a watt isn't going to make or break the efficiency measurement of an entry-level server or high-end laptop.

PCMark 7 Average Power Consumption

If we log power consumption through a workload, even a relatively heavy one, we see that average draw is still pretty close to the idle numbers. Maximum power may spike fiercely, but the usage seen during a PCMark 7 run is pretty light. You can see the drives fall back down to the idle "floor" between peaks of varying intensity.

Averaged out over a complete PCMark 7 run, the 512 GB X210 uses 0.9 W, while the 256 GB model settles in at 0.85 W. That puts SanDisk's drives around the same level as Samsung's 840 EVOs and OCZ's more recent offerings.

Let's plot the log data for more detail:

The distances between peaks comes down to writing used LBA spaces. Basically, PCMark 7 is formatting the addresses the component traces will use, which takes longer on the 512 GB X210 than on the 256 GB version. That's why the smaller drive gets started first.

As far as power consumption goes, there really isn't much variance between the two. Both hit the same idle floor and demonstrate similar peak figures. The higher-capacity SSD simply uses a little more power.

Maximum Observed Power Consumption

Unfortunately, that's enough to put the X210s toward the bottom of the chart in maximum observed power consumption. These drives could use more power in certain workloads or under specific conditions, but this is the highest we saw in our own test suite.

    I logged onto Tom's this morning totally expecting a Kaveri review. What's up?

    Is the warranty 5 years or 3? Last page says one thing, an early page says another.Decent review, decent drives. Has THG considered doing something similar to what the car mags do, where they take certain products and use them for a year? It would be great to capture that kind of longer-term info on certain types of products, especially the kind that wear out (ODDs, fans, cases, HDDs, SSDs, etc.).

    What about Samsung SSD pro 512GB? I bought 2 of these and on that chart is only 128 and 256GB

    @vertexxthere isn't anything particularly exciting about Kaveri going by Anand's review. I shall want for the A10 version with higher clocks

    MLC with 5k write endurance!And affordable and fast?We may very well have a new solid contender in the SSD world

    I agree with Chris. I don't need the fastest bench speeds in a SSD. Most models now are very fast and the user won't see the performance difference. I want reliability and longevity. Looks like this is a smart choice for any new builder.

    sweet finally another company that can compete with intel's 5 year warrenty!

    Can we PLEASE have some normal graphs for once? The graph on page 5 in stupid 3D is so bad it's comical. The "perspective" effect completely screws with the data. This has zero added value and is almost as bad as still using clipart.

    I find it hard to believe that the author has had "literally dozens of SSd's die" on him over the years. This would suggest that many systems have contributed to the demise of many of the SSD's being used, which seems somewhat outlandish. Just the cost factor involved in the purchase of so many SSD's and then having over a dozen of them fail, supposedly also from various companies, since if they were all from the same company it would not really be conducive to good sales. One, or maybe two I could live with, but dozens? No.

    @Duff165 I would respond to your ignorance, but I really, really dislike this "new" comment system that Tom's has foisted on us.

    Agreed. Now it is truly screwed more than ever.
    WTH is will the continuously scrolled unrelated articles, dropped newlines and just plain broken comments.

    For the typical user that only has a few systems at the same time, yes. For someone who works with dozens of systems, the chance for one of them to fail goes up. Constantly building, testing, and reconfiguring machines means you're constantly imaging and re-imaging drives, which wears them out much faster than normal. Perhaps it was a little exaggerated, but it's definitely possible

    Lol. All of the work that went into making page 5 seem like some super-complicated test. That is just HDTune, which can be ran with the click of a button and hardly requires and entire page and horrible graph for explanation.

    Question: Can this drive be used on a personal laptop??

    I don't see why not

    There's actually a pretty huge difference between MLC-SLC translator based emulation and the way that tlc can behave electronically(physically) as SLC independently at the bottom of the translation layer. MLC-emulation has a partially positive and partially negative effect on translator stability, but with a robust controller(Marvell), the net effect on reliability is positive.With TLC as SLC, the effect is nearly perfectly proportionate to having SLC physically present.In fact, it is possible(with manufacturer tools) to take just about any TLC device like a 64GB usb flash drive and make it electronically indistinguishable(nearly) to a ~22Gb TLC flash drive in respect to performance, endurance, etc...MLC emulation is much more nuanced.

    @Duff165. It's very believable that the author could have had dozens of SSD failures, especially if he used some brands like Mushkin. We were building systems using their 120GB SSDs and had nearly 75% failure rate within the first 6 months. Since then, we have used primarily Kingston with a few Intel and Crucial SSDs and haven't had a single failure since.

    Since the major difference between the X210 and the Extreme II is the firmware, can you please test the Extreme II on the new DriveMaster TRIM test and see if they behave the same? SanDisk just turned into a new favorable option for me for my next drive.
