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

Results: File Copy Performance With Robocopy

Microsoft's Robocopy, a directory replication command, gradually replaced the older xcopy. It's multi-threaded, has a ton of options, and generally outperforms Windows' vanilla copy operations. Best of all, it's built right in to Redmond's OS. Especially useful for network copy operations and backups, Robocopy doesn't stop to ask you one hundred questions while it copies over your music collection, either.

The reality of benchmarking file copy performance is that you need something fast to move data from and fast hardware to move it to. This is most important with SSDs. It doesn't matter if your drive can write sequentially at 500 MB/s if the source files are hosted on a USB 2.0-attached external hard drive. We're copying our test files from an Intel SSD DC S3700 to the drives in the chart below, taking source speed out of the equation (mostly). Moving to faster storage would increase the faster test disk's ultimate file copy performance. But what's the point? Most users copying data won't have the benefit of a RAID array of PCIe-based SSD, so relying on just one drive as a source gives us a solid average.

There are 9065 files comprising the 16.2 GB payload. Some of them are huge (up to 2 GB), while others are best described as tiny. On average, that's around 1.8 MB per file. The files are a mix of music, program, pictures, and random file types.

It's fair to say that this chart would look much different if we were copying from a hard drive to a SSD. Even if the disk drive's sequential throughput wasn't a bottleneck, it'd still choke on the smaller files.

The near-identical 256 and 512 GB X210s pull up alongside one another, delivering 288 and 287 MB/s, respectively.

    I logged onto Tom's this morning totally expecting a Kaveri review. What's up?
  • TeraMedia
    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
  • smeezekitty
    MLC with 5k write endurance!And affordable and fast?We may very well have a new solid contender in the SSD world
  • eklipz330
    anandtech has one? sweeeet, later tom's!

    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.

    The hotrod is not always the best choice for the long haul. Sometimes you need the 'steady eddie' like a adata xpg sx910.
