5.0 out of 5 stars Crazy fast and reliable so far, 10 Aug. 2011
Verified Purchase(What is this?)
This review is from: Crucial CT512M4SSD2 512GB M4 SATA III 6Gb/s MLC 2.5 Inch Internal SSD (Personal Computers)
I've only had this drive for about a week but I've put it through its paces to see how it compares to my previous Crucial CTFDDAC256MAG-1G1 2.5-inch Solid State Drive (256GB,Real SSD,C300,SATA 6GB/S).

The answer is... pretty well. These drives are almost identical to the C300 series internally, just with a slightly tweaked and faster controller.

Like the other reviewer, northener, my drive came with firmware 0001. I did some brief initial testing with it and didn't run into any issues before I upgraded to 0002. It's still slightly annoying that Crucial only provide firmware updates as bootable ISO's though, at the very least they should make it easier for people to create bootable USB keys - it's possible to do this manually, but annoying and clunky. So most of you will need a CD-R and an optical drive handy for doing the update it seems.

Aside from that, absolutely no qualms about the drive so far. It's being used as a scratch drive for large video files, and excels at this purpose - the supposedly higher specs of the newer sandforce drives don't translate into real world performance where incompressible files like video are concerned.

Finally, performance. The drive is plugged into a 6Gbps Intel SATA port on a sandy bridge system. Synthetic benchmarks got me sequential reads at ~440MB/s, sequential writes at ~270MB/s, random 4k reads at 22MB/s and random 4k writes at 74MB/s, both higher than those of the C300 (and higher than the specs mentioned on this product page). I don't have any real-world tasks to do on this drive that'll do it complete justice, but I can mux a complete >30GB blu-ray M2TS (reading from and writing to the same drive) in a couple of minutes whilst the drive is still perfectly usable by other applications. No testing done on a Mac, but OSX users might want to check the Crucial forums as there are several people there with issues with these drives in their macbooks.

Four and a half stars for still having a clunky firmware upgrade process but being a brilliant SSD nonetheless.

Edit: Crucial published firmware 0009 for this drive recently, which I've just flashed to, to large performance increases. The drive now benches at ~514MB seq reads, 270MB/s seq writes, 23MB/s rand reads and 76MB/s rand writes, so a large jump in sequential reads especially. 0009 is also much faster initialising the drive on boot and there are numerous other relibaility fixes too. I've also found out that the firmware upgrade ISO loads perfectly fine with unetbootin, making installing it via USB stick much easier. As such I'm now bumping the review up to five stars.
