Crucial BX300 SSDs are ready for an upgrade party

Enthusiasts have known for some time that the best way to improve a PC's snappiness is to move the operating system and programs over from an old-school rotating platter drive onto an SSD. Crucial says its BX300 SATA SSDs are perfect for this type of upgrade. The drives pack Micron 3D MLC NAND chips that receive marching orders from a Silicon Motion SM2258 controller. The move away from the rather disappointing BX200's planar TLC memory could bring a performance resurgence to Crucial's budget retail SSD lineup.

The BX300s come in three capacities: 120 GB, 240 GB, and 480 GB. Crucial's datasheet says that all models share a handful of performance characteristics, at 555 MB/s for sequential reads, 510 MB/s peak write speeds, and a 90K random write IOPS rating. As usual, the larger drives have improved random write speeds. The 120 GB model is rated at 45K random read IOPS, the 240 GB drive improves this figure to 84K IOPS, and the top-of-the-line 480 GB model is said to be capable of 95K random read IOPS.

Crucial says its choice of NAND chips for these drives should deliver excellent reliability. The smallest drive is rated for 55 TB of total writes, equivalent to 30 GB of writes per day for five years. The 240 GB drive's endurance is specified at 44 GB written per day over the same period (totalling 80 TBW), and the big 480 GB model is said to be capable of 88 GB of writes per day-night cycle for five trips around the sun, or a total of 160 TBW.

Crucial backs all three BX300 SSD models with a three-year warranty. The BX300 120 GB is available now for $60, the 240 GB model rings in at $90, and the 480 GB model will set buyers back $150.

    Well done Crucial/Micron.

    Perhaps now we’re seeing the end of the “Race to the bottom in SSD’s”

    The BX300’s and Toshiba/WD Bics and perhaps the Intel 540s-now give
    us an option to Sammys EVO that we didn’t have before……………………

    They still suck; [url<]http://www.anandtech.com/show/11766/the-crucial-bx300-480gb-ssd-review-back-to-mlc/2[/url<] Edit; Forgive my ignorance, I was looking at the BX200 results, this seems like a solid drive(no pun intended).

      +1

      It’s a far better drive than the BX200, but it’s still substantially slower than the BX100 that was released in 2015.

        Can someone enlighten me as to why you disagree with the above statement?

          Because you +1’d the tsk’s comment and tsk made a mistake reading the graphs and then retracted his statement. So I’m thinking his thumbs down trickled down to you.

          As to your specific claim, well, they didn’t have the BX100 in the benchmarks of this review. But going back to it’s specific review and comparing drives that were in both reviews, it looks to be about the same overall. Just a little bit below the Samsung 850 Pro and EVO. Honestly, the only major difference between BX100 and BX300 seems to be the power consumption.

            So a drive that comes out two years later with worse performance and no significant price reduction is a good deal? Weird.

            • cygnus1
            • 2 years ago

            It would be weird. But it’s not dramatically worse performance, and it is fairly cheap considering competition in the SATA drive market today. Comparing to 2 years ago isn’t extremely helpful. The comparison with what’s on the market now doesn’t look all that bad to me.

            Not saying I would buy one, as I don’t intend to buy another SATA SSD that isn’t just a basic boot drive for a home server. Ideally any new machine I build is going to have PCIe/NVMe storage going forward. But if I were looking for a decent sized SATA SSD, the BX300 would definitely be on my radar.

            That’s fair.

      Not sure I’m seeing the same numbers you are. The BX300 does really well in that review, in fact the page you linked shows it doing really really well. It’s in orange, the blue one is the BX200 and is just showing how garbage like it was.

      At worst the BX300 is middle of the pack (of what was tested), but it also is near the top in several tests. The latency tests are right in line with the best of the others tested. One of the only graphs it doesn’t fair well on is the power efficiency during sequential read.

      On top of that, the MSRP is actually pretty cheap, which means you might end up finding it for even less in the wild… That seems like awesome bang for the buck to me. Especially if you’re just buying a small SSD to use as a boot drive.

        I must confess my mistake and ignorance, I was looking at the BX200 results, please forgive me.

          No worries. I think your thumbs down were punishment enough 😉

      Did you read the whole review?

      The drive put in a strong-to-decent showing depending on the benchmark. This is a sharp contrast to the BX200, which was a poor performer across the board.

      The only truly bad score was the 128k sustained sequential read test, which is a bit odd given its performance everywhere else.

      Seems like a missed opportunity not to include the BX100

      • ozzuneoj

      lol… Is this a joke? It performs better than other drives in its price range in nearly every test. Seems like a really nice drive.

    >Corsair says its choice of NAND chips for these drives should deliver excellent reliability.

    Surely you mean Crucial?

      Beat me to it.

      It’s, ahem, [i<]crucial[/i<] that one company isn't mistaken for another. Fixed, thanks for the heads-up.
