Product Description

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.

By K. Trebell TOP 1000 REVIEWER VINE VOICE
Style Name:128GB M4|Verified Purchase
The Crucial M4 is 128GB solid state drive. These drives use a technology akin to that used in flash drives , and seen in the likes of tablets and smart phones, to provide a slim, cool and fast performing storage device for your system.

I'd be thinking about getting one of these for ages as my 1.5 TB Hard Disk Drive had become extremely slow and no amount of defrags and optimisation could improve it that much. I'd tried an alternative 1TB drive but still had very slow times between turning on, logging in and eventually loading my desktop so I could work.

I was aware that SSD's can greatly improve performance but was concerned that they are know to have a shorter life than HDD's and that they won't slowly degrade like an HDD but just stop working (rather than gradually giving bad sectors as Hard Disks tend to).

I took the plunge though and I'm very glad I did, my boot times have improved from several minutes to under a minute even with my system now fully loaded with all my services and the system is extremely nippy now.

It's worth noting that these drives are 2.5" laptop sized. If you want to install them in a desktop then an adaptor like this allows you to attach them Akasa AK-HDA-03 2.5-3.5 inch SSD/HDD Adapter.

Installation was easy. I plugged the drive into the adapter bay and easily slotted this into my tower. I then plugged this into a spare sata port (my P55 mother board has sata 2 so I'm testing at a slower rate than those with sata 3 will get and still very impressed). Following that I booted and went into my BIOS set-up to tell the system this was my primary HDD and to set my boot order.

4.0 out of 5 stars Really fast, pretty small 1 Jun 2011
By Christopher Burns VINE VOICE
Style Name:128GB M4
I picked up one of these a few days ago to complement a newer Sandy Bridge setup. For no reason I could ever figure out, my boot times were terrible with the motherboard (an Asus P8P67 Pro) using a conventional HD - on the order of 3 minutes from cold until the PC was responsive. Connected to a SATA-3 controller, this SSD reduced my boot time to around 35 seconds, and, once the desktop appears, the PC is fully responsive to whatever you want to do. It sounds obvious, but the main thing that differentiates SSDs from conventional HDs is this "snappiness" factor - seek times are completely flat, thus, the only delay is actually transferring data off the drive to RAM for CPU operations (and this drive is capable of >400 megabyte per second bursts). The drive is also completely silent, and it's slightly weird not to hear the usual HD ticking & clicking. You may also need a 3.5" drive bay adapter; physically, the drive is about 50% bigger than a credit card and very light - alternatively, I have seen these drives held in place by double-sided tape - with no moving parts, you can pretty much put them anywhere the data and power cables will stretch. Also, a side effect of the "solid state" part of the drive is that it is largely unaffected by any movements or accidental drops - anything that doesn't destroy the casing will leave the drive completely unaffected - the interior is largely the same as a USB flash drive, but with larger capacity chips and a small controller.

I initially had some trouble with the drive (some stuttering and pausing) after installing Windows7 then Intel's RST drivers (the drive is connected to an Intel ICH9 port), and decided that a re-format would be my best option to completely get rid of the Intel drivers.

5.0 out of 5 stars Excellent. Works great with MacBook Pro. 6 Aug 2012
Style Name:64GB M4
This works very well with my MacBook Pro (15 inch early 2011). However it is necessary to install a firmware update (see instructions below) in order for the SSD to work. Once installed I noticed a dramatic speed improvement. Did a fresh install of Mountain Lion and it's like a new laptop!

Instructions for MacBook Pro (early 2011):

1) Backup your files to an external hard drive with Time Machine.

2) Go to the Crucial website and download the latest firmware (as of writing version 000F). This consists of a .iso and a .pdf guide.

3) Burn the iso to a black CD or DVD using Disk Utility. (The USB option did NOT work for me!). There's plenty of guides/videos on how to burn an .iso if you search the web.

4) Two options at this point: a) Create a bootable OS X install USB so that you can install an operating system on the SSD once it's installed or b) use your Time Machine backup to copy your files to your new SSD. I'll follow option a).

5) Insert the firmware DVD/CD into your Macbook and shut it down. Open it up and remove your current hard drive. Replace it with the SSD and screw everything back in place (again there's plenty of excellent videos online if you're unsure...)

6) Turn on your MacBook. I didn't have to press anything. After about 30 seconds the firmware updater presented itself. You'll be prompted for a 'yes' or 'no'. Type 'yes' and hit enter. After another minute or so the firmware will be updated.

7) Hold the power button to switch off your MacBook. Insert your OS X install USB stick. Power up your MacBook while holding the option key. Select the OS X installer.

8) Once you've booted into the USB installer you'll be presented with a menu. Select Disk Utility.
