Product Highlights
  • 256GB Drive Capacity
  • mSATA Form Factor
  • Micron MLC NAND Flash Memory
  • SATA III Interface
  • 500MB/s Sequential Read Transfer Rate

The 256GB m4 mSATA 6Gb/s Solid State Drive from Crucial is a solid state drive sporting a reduced size form factor making it suitable for ultrathin laptops. This versatile drive can be utilized as a drive capable of storing your data or you can attach this drive to the mSATA socket on your motherboard for added cache memory. With a MTBF (mean time between failures) of 1.2 million hours you can rest assured this drive will be there when you need it.

Reduced Size Form Factor
Measuring in at about one-third the size of a standard business card 1.2 x 2" (3 x 5 cm), the Crucial m4 mSATA is designed primarily for ultrathin laptop users who want to dramatically increase their system's performance. Featuring the same advanced controller technology, Micron custom firmware and high-speed synchronous MLC NAND, the Crucial m4 mSATA SSD is engineered to deliver the same fast performance as the Crucial 2.5" SSD - in a smaller mSATA form factor.
Thin Form Factor
Because of its mSATA form factor, the Crucial m4 mSATA SSD can do things that hard drives and other SSDs often can't. Save system space by mounting the Crucial m4 mSATA SSD directly to the mSATA socket on your motherboard and free up a hard drive bay in the process. You can effectively keep your existing hard drive and use the Crucial m4 mSATA SSD as a cache to accelerate the system's performance. It's designed to work as a cache or as a standalone SSD for ultrathin laptops. No matter how you use the Crucial m4 mSATA SSD, take advantage of high-performance storage in a reduced form factor size.
Consistently Fast Speeds
This Crucial SSD treats 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 can't be compressed, resulting in SSDs that often deliver drastically slower speeds than originally advertised.

      Accelerator for Drobo

          Sweet little accelerator for my Drobo Mini. I give 4 stars because the performance difference is subtle. I use the Mini as a primary data source, so the little boost in speed is important.

          In this scenario the mSATA card does not count as storage space. It only accelerates performance.

          My primary use is photo processing. I am working with files up to 10 gb. (I am not a gamer)

          I purchased this drive for my XPS 8500 system. Easy installation and the 2 small mounting screws were included in my package. I re-installed Windows 8 and a few games on the SSD and have had no problems whatsoever. Very pleased with this drive in my system.

          again, sometimes no news is good news

                Comments about Crucial 256GB m4 mSATA 6Gb/s Solid State Drive:

                I purchased this SSD along with 5x 4TB drives for my Drobo 5N. If my understanding is correct it's supposed to work as an additional sort of read/write cache to improve performance and/or reliabilty of the Drobo units. Unfortunately since I never used the Drobo without the cache, I honestly can't say if it improves the performance or not, and at this point I don't see myself removing it just to determine whether i've wasted my money.

                The consensus is that the mSATA SSD benefits in the Drobo units diminish after about 60GB, so again...it's hard to say if the extra capacity or performance of the Crucial SSD is really helping. The Drobo Dashboard seems to like it, and keeps saying it has "100% Life" left. That's good, right?

                It was easy to install in the bottom of the Drobo.

                          I plugged the drive into a Lenovo W530 Thinkpad. I was disappointed that a mounting screw was not supplied with the SSD. Fortunately, Lenovo provides the screw.

                          I use the unit as my boot drive, so that the system boots quickly and the main hard drive serves as a data store. Everything worked as expected. My Thinkpad recognized the SSD as soon as I powered up. Hopefully, it will hold up to 24x7 operation for many years.

                            Having this allows the Drobo to cache your most frequently used data. It makes a very big difference in the access speed.

                              Out of box, the product needed to be formatted which could be a little difficult for non-tech users. Once formatting is complete this solid state is amazing. Blazing speeds on power on (Windows8 start up takes ~13 sec on my Lenovo W530), during writing all of my music I was getting close to 40 MB per sec and when reading I was getting about 35 MB per sec. Very happy all around and if you are looking for speed you will max out SATA2 speeds with this SSD.

                                  Even on SATA II this thing is blazing. I have it set up with UEFI boot and it outpaces my 7200rpm easily. File transfers are near instant.
