The Crucial m4 SSD
Award-winning quality. Award-winning performance.
The award-winning Crucial m4 SSD delivers powerful performance gains for SATA 6Gb/s systems. Designed to empower your system, the Crucial m4 SSD offers faster application load times, faster boot times, and increased durability compared to a traditional hard drive. The results speak for themselves: blazing-fast sequential read speeds of up to 500 MB/s for any file type.
Cutting-edge technology. Quality component testing.
Built with advanced controller technology, Micron proprietary firmware and high-speed synchronous MLC NAND, the Crucial m4 SSD is engineered to deliver consistent, blazing-fast SSD performance. From the extensive research and development that led to its ultimate design, to the hours of testing and validation spent on each NAND component, to rigorous compatibility testing in the Crucial Performance Labs to ensure component functionality, the Crucial m4 SSD is built to last.
Consistently fast speeds. No exceptions and no fine print.
There's a reason the Crucial m4 SSD has garnered numerous international awards since its launch it does what it's supposed to do. No matter what kind of files you are working with on a Crucial SSD, you'll experience high speeds with no drop in performance.
Unlike other SSDs on the market, Crucial SSDs treat all files the same, regardless of whether they are compressed or uncompressed. This is important because the files most people use everyday are videos, mp3s, advanced graphics files and zip files - are compressed files and thus unable to be compressed any further. While many SSDs on the market achieve faster speeds by using file compression, many of the most common file types can not be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, you will never have this problem!
Crucial quality you can depend on.
Crucial is a trusted name when it comes to SSDs, and that's no coincidence. As a brand of Micron, one of the worlds leading manufacturers of SSDs, we work with our engineers to design, refine, and support our drives. With over 15 years of experience in the memory industry, NAND component testing, and the ongoing development of advanced technology, we continue to innovate without sacrificing what has made us great: high-quality upgrades and outstanding customer service.
Crucial SSDs. Performance you can trust.

Drive developed a fault after 30 months, killing my Windows 7 x64 install, and their tech support were very helpful in diagnosing and fixing the problem, but IF it had been a hardware fault, their policy was to give me a tiny £11 pro rata credit for the remaining warranty term to spend only on crucial.com.... not to replace the drive (they don't have any left now), or even offer a fair and significant discount off a new drive (I'd gladly accept 50% off a new 128GB). I can understand this approach, and it's common with some GPU mfrs, but it still sucks, when your only cheerful thought is that I've lost my Windows install, but hey, at least I'll get a new drive under warranty to cheer me up. But no, you basically get an apology and a tiny bit of cake, now give us another £50 please.
Crucial customer relations rang me back to do a survey a few days later, I explained that surely if the return rate is usually low, it makes sense to keep that tiny number of customers happy by offering them a fair solution. If the return rate is high and they annoy lots of their customers, they won't stay in business for long.
Thankfully my issue seemed to be related to trim, rather than hardware failure, although time will tell if the fault reoccurs. I'd be more wary of buying another Crucial SSD in future.
14 sec Windows 7 boot times, instant launch of the apps and access to any data, insanely fast internal transfers when muxing.
512 GB capacity means I can finally have all photos and Lightroom catalog on the laptop and still have enough space for games/apps and ~200GB spare capacity to make sure the firmware can cycle flash cells well and don't reduce its life.
Build quality is excellent - as with all Crucial (Micron) SSDs and included data transfer kit makes the swap to a new drive a doddle.

Well deserved 5/5, recommended!
I recently purchased a fairly high spec pc with an SSD C drive. Like many others I was impressed and this got me wondering what such a drive would do for my old pc. This is a 2006 AMD dual core 2400hz, 2GB RAM, dual nVidia 7800GT graphics cards in SLI, running XP. I took a chance for £67 and purchased a crucial M4 64GB SSD. I did this almost just out of curiousity. I did a complete re-boot. This involved screwing the 3.5" bay adaptor to the SSD and sliding it in where my old drive used to be. I transferred the SATA and other connection which pull off and push on easily (I am no expert). I then started the pc up with my recovery disc that came with the pc by putting this in the first DVD/ROM drive. It took about 25 mins to load XP, which is very fast in itself. It is worth copying your drivers before you re-boot as otherwise various things like your Ethernet may not work. So after the initial re-boot I had windows working but with no Ethernet. I intalled my Ethernet driver. It took another 30mins to download the 150 ish updates since my rather old version of XP was first issued. I did the recommended updates only, as opposed to the custom ones but you do have to repeat this about 4 or 5 times as each new update triggers another batch of updates, re-starting in between each batch of updates. So what was the result?
Well my old PC would start up in exactly 2 mins 30 secs until fully functional. It now achieves 35 secs. Things like the internet explorer seem far more snappy and instant. Games do not play better or at higher resolution as far as I can tell, there may be a marginal improvement, but they do seem to load up noticably faster, I would estimate at least 3 times. This is providing they are loaded onto the SSD of course.
So if you want to spruce up your old pc this seems to be an excellent option.
If you buy some extra cables you can still use your old drive to take the volume items such as photos, music and the like.
I did not adjust the bios, which I have read elsewhere might be desirable, so it is possible I may not have squeezed all the performance out of the SSD but either way I am very pleased.
