Crucial M4 CT128M4SSD2 2.5″ 128GB SATA Benchmarks in an Lenovo x220

I recently purchased an awesome little laptop…the Lenovo x220.

Specs :

Intel Core i7-2620M Processor (3.4GHz, 3MB L3, 1333MHz FSB) w/ USB3
Genuine Windows 7 Home Premium 64bit
12.5″ Premium (IPS) HD (1366×768) LED Backlit Display, Mobile Broadband Ready, 2×2 Antenna
IntelĀ® HD Graphics 3000
4 GB PC3-10600 DDR3 SDRAM 1333MHz SODIMM Memory (1 DIMM)
250 GB Hard Disk Drive, 5400rpm
ThinkPad Battery 29++ (9 cell)
Intel Centrino Advanced-N 6205 (2×2 AGN)

I decided I wanted to get an SSD, and opted for the Crucial M4 series. It required a little tweaking to get into the x220. I had to unscrew the middle spacer, and it slide right in.

Benchmarks in IDE mode:

Benchmarks in AHCI mode:

These aren’t bad numbers at all, considering the manufacturer rates them at :

Sequential Access - Read
Up to 415 MB/s (SATA 6Gb/s)

Sequential Access - Write
Up to 175 MB/s (SATA 6Gb/s)

What I really like about this drive is the low power consumption, SATA 6/Gbp/s, as well as the 40,000 IOPS. I still think SSD’s are the number one upgrade for any PC (as long as they are SATA 3+ capable). They just make the system that much faster.

Hello Vivi,
I think a lot of X220 owners would like to know just how fast the SATA interface is on you X220. Have you run any tests on your X220 and Crucial m4? Have you tried CrystalDiskMark? What is the maximum sequential read/write speed in your X220?

The 274 MB/s read seems slow, considering that the drive is rated at 400+ MB/s.

Is the X220 using a SATA 2?
