Product Description

The 128GB CRUCIAL M4 2.5IN SATA 6GB/S.What's in the box: Crucial 128GB m4 SSD 2.5" Solid State Internal Drive and 3-Year Limited Warranty.

From the Manufacturer


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. Theres a reason the Crucial m4 SSD has garnered numerous international awards since its launch, it does what its supposed to do. No matter what kind of files you're 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're compressed or uncompressed. This is important because the files most people use everyday 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 cant be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised. With the advanced technology of a Crucial SSD, however, you'll 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.

Install it to the SATA 1 or 2 ports for SATA III, preferably Intel designed ports if you got it or primary AMD if an AMD board. Read your manualif you must. This is because third party controllers like Marvel simply are not as fast as the Intel.2. Do a google search for "Sean's ssd optimization guide" and click the first link. Then go to page one. Follow all the instructions to the T.Those are the two most important things.Also do NOT clone your previous hard drive. It turns out badly becauseyour cloned version of Windows will not automatically turn Trim onalong with other optimizations. Install Windows fresh. This is the biggest upgrade of yourcomputers life so don't skimp by saving 10 minutes.I am on my third day with this drive and it is outstanding.My computer boots in less 17 seconds from pushing power button to everything loaded on desktop.That is baseline no startups except chrome steam and sandiebox.A person who properly sets this up will get good use out of the drive.To be honest If I get one year of great performance out of drive I consider it good and I will buy somethingidentical to it.On a side note.

When somebody says they got horrible tech supportfrom crucial either they were expecting too much too fast or do not understand warranty processes.

This SSD is produced in conjuction with Micron who owns the fab to creating the chips found on manyother ssd's sold by other companies. This is why they are able to offer strong performance and reliability for this low price.Also if you are considering a intel's pricier ssd due to their 5 year warranty consider that this is a solid state drive with no mechanical parts. So if it gets past theinfancy death that ALL electronic devices incur due to no falt of their own then this will undoubtedly last for years. Infancy deaths will occur within 3 months. Remember youhave warranty for a reason. So once it hits the 3 month mark you should sleep a little better.*Update 6/5/2012 - I still have this running fine with only a 17GB windows foot print and no read/write errors recorded from Windows so far. It is treating me well*That is all I hope this review has been helpful.Giz out.*Update 4/16/2013 - This is still running strong and no complaints at all. No Stop Screens (blue screens of death) slow downs or hiccups.

Also Trim does seem to be doing its job. Almost a year later and just as fast.

Zotac Nvidia 560TI
Intel I5 2500k modestly bumped to 3.5 based.

I do desktop support but this was MY first ssd install.
I did a lot of research by comparing products and decided to settle on Crucial.
The price to compatibility and positive review ratio is what had me decided.
However the benchmarks I got out of it actually shocked me.

I received this M4 128GB at 0309 firmware which is second to latest. I ran benches
with this and will run again with newer firmware when I feel there is a need to.

Must do two things to this SSD:

1. Install it to the SATA 1 or 2 ports for SATA III, preferably Intel designed ports if you got it or primary AMD if an AMD board. Read your manual
if you must. This is because third party controllers like Marvel simply are not as fast as the Intel.

2. Do a google search for "Sean's ssd optimization guide" and click the first link. Then go to page one.
Follow all the instructions to the T.

Those are the two most important things.

Also do NOT clone your previous hard drive. It turns out badly because
your cloned version of Windows will not automatically turn Trim on
along with other optimizations. Install Windows fresh. This is the biggest upgrade of your
computers life so don't skimp by saving 10 minutes.

I am on my third day with this drive and it is outstanding.
My computer boots in less 17 seconds from pushing power button to everything loaded on desktop.
That is baseline no startups except chrome steam and sandiebox.

A person who properly sets this up will get good use out of the drive.

To be honest If I get one year of great performance out of drive I consider it good and I will buy something
identical to it.

On a side note. SSDs while sturdy are like anything else that has transistors in it.
They are prone to premature failure due to things like your UPS carrier playing catch with it
or a person discharging static to the device because they live in a cool dry air climate.

Always install your SSD with an ESD wrist bracelet. You can buy one off amazon for a few bucks to save your computers life.
I whole heartedly believe that ssd's that are not functioning right is 80 percent of the time is
