Crucial RealSSD C300 (64 GB)

Tom's Hardware's Summer Guide: 17 SSDs Rounded Up

The RealSSD C300 is the fastest SSD when it comes to throughput and data transfer. We looked at the 256 GB model a few months ago, and Crucial has made notable progress since then. The drives use Marvell’s 6Gb/s 88SS9174-BJP2.

However, the 64 GB model reviewed here is a far cry from the performance we saw with the 256 GB drive. Although read throughput and total bandwidth are similar and clealy pass the 300 MB/s line, the 64 GB version is limited to just under 80 MB/s on sequential writes. Fortunately, there's hardly any performance drop over time due to wear leveling and write amplification. The 80 MB/s line is dependable, ensuring that the drive will remain much faster than any 2.5” hard drive and superior to most 3.5” drives in many circumstances. Be careful if you require high performance on 4K random writes, though, as most other drives in this review are between 2x and 4x faster.

Crucial's I/O performance is no match for the SandForce SSDs when it comes to file server, database, and workstation workloads. The only exception is the Web server test, which doesn't require writes, and hence really rocks on the RealSSD C300 64 GB.

    Where are you getting your prices for the Mercury Extreme? On OWC's site, they list the 120GB Extreme Pro for $319, and the 100gb Extreme Pro RE (RAID ready, with more overprovisioning) for $369. Not the 399 you mention. The most fair comparison is the 120GB Extreme Pro, which I just purchased for my laptop, and its price is just about in line with the other Sandforce drives out there. plus, you get OWC's awesome warrantee, which to me is worth the extra 20 or so dollars.

    >_> i just ordered a crucial c300 64gb lol

    It had to be done, i've been waiting ages to get one and tbh i got it for £108 which is nothing compared to a mobo/processor upgrade but will deliver so much more performance.

    Its only small but i have 2TB already for storage, i just need something quick for windows

    On the second page you write the following:

    "You can recognize these both by the performance discrepancy between reads and whites and by the exterior"

    Shouldn't that have been "write" rather than "white"? Just a small nitpick, thanks for doing this roundup!

    Did I miss something? Why do we have the Kingston drive in the final tables but not in any of the tests?

    I admit I skipped straight to price/performance charts. The text mentions SandForce SSDs, but this name is not on the graphs anywhere, which is a bit troubling. Yes, my lazy eyes will search the article again for the correct relation between fantasy name and manufacturer. Another nitpick.

    ...But what the hell, the Crucial drives show up on the top 1/4 of all the graphs that matter. I smell a Christmas gift for myself coming up...

    Or maybe it is VERY late, and I am VERY sleepy. Otherwise the Crucial's C300 FTW.

    GoneMad: they are referring to the Sandforce controller the different SSD's use ;)  which is better then the other controlles some SSD's use so check out each drive which controller they use and you figure it out
