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.

Two years before failed (common problem I discovered), the warranty isn't what you may think.

Reviewed in the United States on October 25, 2014

Capacity: 64GBVerified Purchase

After 2 years of use, this drive failed me. I purchased this as a dedicted OS drive, everything worked fine until about a month and a half ago, right around the 2 year mark (the warranty for this is 3 years), then it suddenly stopped, the error was "MBR Error." After doing some research, I found this was common with this drive, and the problem was the drive would no longer function and be detected by windows. I tried all the troubleshooting and had an image of the drive saved about a year prior, which I was able to get the drive to detect and re-image windows. Again, everything worked good for about another month and the same thing. Now, no matter how many "power cycles" as Crucial calls it, the drive will not be recognized. I spoke to a representative from the company and he was very helpful and made it sound good, but when I provided the information over e-mail, here is a copy and paste of a portion:

"Hello,

Thank you for contacting Crucial. Unfortunately, we are currently out-of-stock on replacements for your CT064M4SSD2 and do not have a confirmed date on when identical replacements will be available.

Our only immediate warranty option we can offer an in-store credit in the amount of $16."

Crucial has offered me $16 of in-store credit, which will probably be about $10 after I pay to ship their broken product back, still under warranty. I don't know about you, but this is a sham deal. If you asked me to review this product any time over the past two years before this happened, I would've given it 5 stars and everything was exceptional. But, I think the final outcome of this company is important for you to see. Their "fair market value" they determined was $16, for something I paid $90 bucks for that stopped working on its own under the warranty period. I thought this company and drive was going to be a great purchase, this experience has made me never purchase from the company again. Thanks for taking the time to read this, and I hope it saves someone from running into what I did.

7 years of reliable service

Reviewed in the United States on June 9, 2019

Capacity: 512 GBVerified Purchase

I realize this is a discontinued product, but I thought I would provide some historical context. Most if not all of the 1-star reviews had early on failures. I can understand their frustration, I had a very expensive (at the time) Samsung SSD fail on me in less than a month. It happens.

This was one of the first SSDs I ever bought, along with an Intel 330 series. Neither gave me any issues whatsoever in 7 years of constant on use, and were even used in multiple system builds. Kudos to both manufacturers.

So the bottom line seems to be that if they work past the first few months, you can probably expect them to endure for many years. Just make sure to take backups!

After 8 Years . . .

Reviewed in the United States on January 27, 2021

Capacity: 256GBVerified Purchase

Installed this drive as a test of the then-new SSDs on my main graphics computer; time was up on WIN7 so decided to image the drive to a new SSD in order to test upgrading to WIN10 on the newer SSD.

Before removing the SSD- using Crystaldisk to check its health- I was surprised to see there were 71,919 hours on the drive. Yes- seventy-one thousand, nine hundred nineteen hours.

This is my main computer for email and Adobe CC, on 24 hours a day; images were made to rotating SSDs whenever software updated and daily perishable backups were standard.

Overall, the SSD has given a boost to the speed on an older laptop (and battery life, while reducing heat), and each of my older desktops in the house.

Survived over 8 years. Couldn't be happier.

Reviewed in the United States on December 3, 2020

Capacity: 128GBVerified Purchase

Survived a little over 8 years so that's a win in my book. Purchased in June 2012 and it won't recognize in any PC as of December 2020. It wasn't used very heavily for its whole life. It was my primary OS drive in various computers for the first 4 or 5 years. I like to experiment with different hardware and OS's.

The last years of its life was spent in a work computer whose only purpose was to be a barcode scanner for our job tracking software. The drive died after we had a power outage so there's a good chance it would've stayed alive if we had a UPS surge protector for the computer. Either way, no complaints.

Fantastic drive, rubbish warranty.

Reviewed in the United Kingdom on September 6, 2014

Capacity: 64GBVerified Purchase

Superb SSD when working, but marking down 1 star because the 3 year Crucial warranty is virtually worthless.

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.

I'm technical and this baby is good

Reviewed in the United Kingdom on September 10, 2013

Capacity: 64GBVerified Purchase

I foolishly dropped my wife's Dell Vostro.

The old 2.5 inch disk somehow broke (I tried another from a different machine before I bought the item this review refers to). You just need this disk and nothing else for a vostro...the existing disk cradle will work.

Reinstalling windows seemed faster than usual, maybe I was imagining it? Windows 7 even found the licence key somehow which I was a bit worried about (look underneath the battery ie take the battery out if you are worried you don't know what it is).

To cut a long story short.

I did the windows benchmark test and this disk scored higher than the previously disk and, interestingly, higher than my reasonably high spec RAID5 disk array on my server, which cost me MUCH more to buy and much more time to install.

So these babies are almost certainly quicker than what you already have.

They are quiet and because there are no moving parts i imagine they are cooler and use less power.

Downsides:

The cost per Gb is more...but I don't have THAT much stuff: 60Gb is fine for a laptop for me. All of my storage is on my home server.

I already kept my disk nice and tidy and on other machines I use different drives/arrays for the OS and for files and for APPS. So if I upgrade those the speed increase won't be that much.

The speed increase will be limited by whatever is the bottleneck in your system. For me it's memory; for you it could be your CPU and it will depend on what you use your PC for. It will almost certainly take away the disk as a bottleneck however.

It speeds up startup quite a bit...but then again if you use hibernate it won't be massively quicker. but it will be noticeably quicker...then again how often do you start a pc each day?

for a top end system I drool at the possibility of putting a few of these together as a raid array...if indeed any cpu/memory is fast enough to deal with that!!!

I will buy more solid state hard drives as the need arises....no more old disk for me I will re-use the many I already have.

now before i heap praise, i will quickly say that every pc or mac, has its own build. you have to take into account what hardware you have to establish if you have the capacity for high speed data transfer. i have seen a lot of people switch to SSd thinking there lives will somehow be different. that the wife will stop nagging, Eastenders will be cancelled from our telly and the lotto will come in.

sadly none of those things are likely. you need sata 3 and a half decent mobo.
will it boot up much quicker providing im not trying to give a 10 year old pc a kick in the pants?? yes, yes it will. mine went down from 2 minutes to about 27 seconds and everything opens quicker and basically its a much more responsive machine.

SSD's and this model especially, have been around long enough now to have a track record for consistency. you dont have to move the page file to another drive. its a myth. its not anyones fault, its just wrong.
we believed the read and write process would kill the chips and give it an early death. nope its fine.
It produces almost no heat and clearly no moving parts. i have used crucial for sometime now and will carry on with this make when i purchase the 960gb model. i can hand on heart say this is the one for you. superb tech that is thankfully getting cheaper each year so tuck in

SSD prices having reduced from extortionate to merely expensive, I ordered this gadget to liven up my four-year-old Dell Inspiron 1564.

Popping the new arrival into a docking bay (only USB2 on this computer) I used a downloaded copy of EaseUS Partition Master Free to copy the operating system partition to the SSD. This took several hours (perhaps three, I went out before the job finished) and left me with only the work of removing the service panel from the bottom of the laptop and swapping the hard drives. Four screws to take the drive caddy out of the chassis, another four to take the HDD from the caddy. The air turned blue, these last screws being difficult, and me needing pliers on the screw driver to shift them; Dell had glued them in. Putting the laptop back together was easier and the machine now boots to the password screen in less than half a minute.

The OS copying operation was relatively easy, as otherwise I'd have sat in front on the computer feeding it the Windows disc, the Office disc, and waiting for the three or four hundred Windows Updates to download, before I fed it the other software discs...

Running the Windows Experience Index again (as you must do when you install an SSD) Windows re-ran only the Disc Operations score. So the scores for the (Intel i3) Processor 6.2, RAM 5.9, (Intel integrated) Graphics Desktop 4.6 and Graphics Gaming 5.1 remained the same but the Disc Operations score went from (WD Scorpio 5400) 5.7 to 7.6.

Windows 7 changes some settings for SSDs, as some attributes such as System Restore cause undue wear on the SSD. So I deleted the obsolete restore points, and fired up Partition Master again and deleted the Recovery partition and expanded the C: partition into that space, which worked like lightning, not being restricted to USB2 speed. You don't run disc defragmentation on an SSD either.

I ordered the SSD on Wednesday evening, it was despatched promptly on Thursday, and the FedEx man got me out of the bath on Friday.

Why only four stars? The drive's firmware is version 040H, and I'm currently working out how to flash it to the current version of 070H downloaded from the Crucial website; and Argus Monitor reports no temperature sensor on this drive. Both of these things suggest that the SSD's been in a warehouse for a year or two.

Easy, good value for money, straightforward

Reviewed in the United Kingdom on February 29, 2012

I'm using this SSD for a dual boot Windows 7 and Ubuntu 11.04 system. I felt that 256GB was appropriate for a dual-boot system. 128GB might not be enough for all of your games and applications if you're going to dual boot.

The Windows partition currently has Photoshop CS5, Lightroom 3, Office 2010, Visual Studio 2010, Visual Studio 11, IntelliJ, PyCharm, Skyrim and Mass Effect 2 on it, and they run fast. Keep in mind that although bootup time is often brought up as a great feature of having SSDs, the real benefit is while running applications - you won't keep rebooting your machine all the time so boot speed should not matter much... but you do use applications constantly. And on this SSD, applications start and run faster and generally feel snappier, especially where disk operations are involved. Even the browser is faster because of the hundreds of small files it is accessing.

When setting up for the first time, I remembered to install Windows first. Install was fast, and right after, I disabled defragmenting as well as indexing services and superfetch.

When installing Ubuntu, I moved /tmp, /var and swap off to another partition. I kept everything else on the SSD itself, even /home. However, from /home, I created symbolic links to Videos, Pictures and Music, to the mechanical hard drive, since those folders would be way too large. This means that my /home as well as the thousands of files used by other applications in hidden folders would be accessible faster. I also changed fstab to use noatime,nodiratime,discard when mounting the SSD partition.

I also had a look at a lot of SSD tweaking advice and the problem is, some of them can go overboard in terms of telling you what NOT to have on the SSD. They'll tell you to get the SSD then move EVERYTHING off the SSD. There is no benefit in doing this and the 'life' that you are saving only really applies if you are a data center. You, as a home user, will be just fine keeping your main apps and data on the SSD. Just move the 'huge' stuff (your music and video collection) off.

As a developer, I'm enjoying this a lot now because all of my IDEs (PyCharm, VS, IntelliJ, Eclipse) are fast and snappy... they no longer feel like clunky dinosaurs and are suddenly a joy to work with.

Installation of both OSes posed no problems, both of them worked with the SSD perfectly. For best results, use this with a SATA6 controller on your motherboard and make sure that the SSD is plugged in to port 0.

You will also see that this product is often bought with a mounting bracket. It is not necessary. There are no moving parts in the SSD so you can do as I did and let the SSD hang at awkward angles inside the computer case. The SSD is small and really light so the SATA/power wires dictate where it'll go when given the freedom. If a bit of anxiety kicks in, use some tape or a rubber band. The only reason to get a bracket is for organization and cleanliness.

This SSD came with firmware version 0009. Upgrading to 0309, which is the latest at the time of writing, was easy - you get the ISO, burn it to a USB drive, reboot and run it. Done.

I wouldn't call this a must-have. Your computer is fine without it, and you are probably happy with your computer as it is right now. However, this is one of those things which, once you have experienced, you will not want to abandon. My future builds will now always include an SSD.
