Crucial BX100 250GB SSD Review

May 15th, 2015 Mike Leave a comment Go to comments



Not so long back we took a look at the Crucial replacement for their budget SSD the MX100, the Crucial MX200. Admittedly we were impressed by its price, but more so by the SSD having similar performance to that of the fastest and most expensive SATA III based SSD available. What we have here today is a little something that might crash that little party. Okay, so technology changes all the time and gets better by the day, but would you really expect the new potential king of budget SSD’s to be produced by the very same company?!

So here we have the Crucial BX100 250GB (CT250BX100SSD1), a 2.5″ SATA III based SSD with a Sequential Read speed of 535MB/s, Sequential Write speed of 370MB/s, Random IOPS Read speed rated at 87k and Random IOPS Write speed of 70k. Yep, I already know what your thinking, nothing out of the ordinary and no newfangled technology to get us all excited… We then of course have the price, which at approximately £75 for 250GB of SSD storage is actually pretty exciting!

Let’s take Crucial’s latest little number for a spin (or not, its an SSD and features no moving parts…).

Boot up almost instantly. Load programs in seconds. And accelerate demanding applications with ease. It all starts with ditching your hard drive.
Engineered to outlast and outperform your hard drive, the Crucial BX100 SSD makes nearly everything on your computer faster and more efficient.’

Much like the Crucial MX200 and most Crucial SSDs before it, the Crucial BX100 arrived at pcG within a rather simple, but stylish looking box that isn’t a lot bigger than the SSD itself. The front of which is a blend of blues with a large angled image of the BX100. Running down the right and in the background we have the BX series name, the lower left the SSD capacity; 250GB, then along the top and inside a matte silver border the Crucial logo and model name along with several mentions of the product being a Solid State Drive.

Over on the back we are told lots of interesting information about the Crucial BX100. Okay perhaps that’s a lie. We do find a little information on the box contents, limited three year warranty, along with an address for the Crucial support webpage and instructions to visit it for an installation guide and warranty information in several languages.

Flipping open the box lid reveals the Crucial BX100 to have adequate protection. The SSD itself sealed within a metallic anti-static bag, then held in place by a thin black plastic tray.


Crucial BX100 250GB - contents


As is the case for many SSDs, the box contents for the Crucial BX100 is unsurprisingly very light, containing just the SSD itself and a 9.5mm adapter bracket (would you really need anything else?!).


At the time of writing the Crucial BX100 250GB is retailing for approximately £74 on Amazon or £75 at Overclockers UK and offers a 3 year limited warranty.

First Impressions


Crucial BX100 250GB - front Crucial BX100 250GB - back


As with any other Crucial SSD, the BX100 features a metallic casing with a large blue sticker on the front. This sticker features the Crucial logo and gives us the series name (BX), then tells us the BX100 is a 2.5-inch Solid State Drive. The radial of blues emitting from the right make the SSD seem a little brighter than that of its brethren, in a rather refreshing fashion. If I’m honest I quite like it.

Then over on the back of the Crucial BX100 we find a white specifications sticker with the model, serial and part number. We typically have a screw hole mount in each of the four corners and to the left both the SATA power and data connectors.

As with many other SSDs on the market the Crucial BX100 doesn’t look bad at all, but just like any other SSD currently available, nothing exceptionally exciting to look at. Perhaps now we are seeing more cases hitting the mainstream that happily show off 2.5″ storage drives with display mountings, we might start seeing some with LED illumination?


Testing Methodology/Setup


Our Test Rig for this review (shown below) was treated to a fresh install of Windows 7 Professional N 64Bit (Service Pack 1) with all associated Drivers installed. I also ensured that AHCI was set in the UEFI (although this is now the default settings for most modern MBs). The drive was connected to the Intel SATA 3 (6GBs) port (SATA3_1) of the ASRock Fatal1ty Z97X Killer motherboard. No special or other BIOS/UEFI options are required…

    Hardware Performance


    We use PCMark 8 to help ascertain Gaming performance. The test used measures the performance of the drive while loading real game data for both World of Warcraft and Battlefield 3. In addition to this we will also use ATTO Disk Benchmark to confirm the drives claimed performance levels.

    • ATTO Disk Benchmark


    Okay, so perhaps the Crucial BX100 is not the fastest SSD we’ve tested using the ATTO benchmark, but it certainly shows it is no slouch either. With a Sequential Read speed of 563MB/s, it is in fact faster than its quoted 535MB/s speed. Which also makes it very nearly as fast as the MX200, which is the fastest drive we’ve tested to date! Where the BX100 does lose ground in performance over the MX200, is in its sequential write speed. It is still a little faster than its 370MB/s quoted speed, but at 377MB/s not by much. Of course as Gamers is the Write speed really as important as the Read?! The answer to that is obviously no.


    • PCMark 8 Storage Test

    Toshiba 1TB Hybrid SSHD 91.6 s 285.0 s
    Western Digital Black 1TB HDD 123.6 s 303.9 s


    We use the PCMARK08 benchmark to test real world loading times for both World of Warcraft and Battlefield 3. With a load time of 58.5s for World of Warcraft we find the Crucial BX100 narrowly behind the top three SSD’s by just 0.7 s. Then during the Battlefield 3 test just behind the leader of the pack by 0.8 s with 133.6 s. Which in the real world is practically negligible as you really wouldn’t notice the difference at all.


    Final Thoughts


    Have Crucial just beaten themselves at their own Game with an even cheaper entry than the MX200 to the budget SSD arena, in the form of the Crucial BX100 250GB?

    The Crucial BX100 arrived at pcG within a small flip top box not much bigger than the SSD itself. With the radial of blue emitting from one side, you could tell unmistakably that this was certainly going to be a Crucial product. The box contents were adequately packaged within an anti-static bag, then held in place with a thin plastic tray, all safe and sound. Of course it would be difficult for the contents not to be safely stowed, given there was just the BX100 SSD itself and a 7mm to 9.5mm spacer, but what else do you really need?

    Just like its brethren, the Crucial BX100 SSD housing is of a textured matte silver colour, with a blue and black sticker on the top revealing it be be a Crucial product. A colour combination that might not be to everyone’s taste, but it’s certainly not intrusive enough to be a problem when installed in to any Gaming rig. Personally I rather liked the brighter blue used on the sticker and believe it gives the BX100 a slightly cleaner and a little fresher aesthetic look than that of its stable mates.

    Given the Crucial BX100 is currently one of the (if not THE) cheapest SSDs per Gigabyte available, you’d be forgiven for thinking less money equals less performance. Yet the Crucial BX100 shone brightly throughout our benchmarks and was shown to be one of the fastest SSDs we’ve tested here at pcG to date! It’s quoted Sequential Read and Write speeds of 535MB/s and 370MB/s, were very nearly thrown out of the window when the ATTO benchmark showed them to be 563MB/s and 377MB/s respectively. Then in the real world loading times within the PCMARK08 test for World of Warcraft and Battlefield 3, it ranked right up near the top of the table with a maximum of 0.8 s keeping it from the very top slot.

    We all know that SATA III based SSDs have pretty much hit the ceiling where speed and performance is concerned, which means when it comes to performance in Gaming there is actually very little difference from one drive to another. Which is where the Crucial BX100 comes in to play. It may not be the very fastest SSD available and to some it may not even be the prettiest, but there’s no doubt about it being amongst the top performing drives we’ve tested so far at pcG. More importantly is its price, at approximately £75 for 250GB, the Crucial BX100 offers you value, performance and capacity, in what is possibly the best all round package when it comes to SSDs. You could even say the Crucial BX100 is standing on the shoulders of giants.
