The Crucial/Micron M500 Review (960GB, 480GB, 240GB, 120GB)
by Anand Lal Shimpi on April 9, 2013 9:59 AM ESTAnandTech Storage Bench 2011 - Light Workload
Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).
The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:
| AnandTech Storage Bench 2011 - Light Workload IO Breakdown | ||||
| IO Size | % of Total | |||
| 4KB | 27% | |||
| 16KB | 8% | |||
| 32KB | 6% | |||
| 64KB | 5% | |||
The story in the light workload looks a bit better. While the M500 still pulls up the rear, the margin of victory for the 840 and other drives is much smaller.

I was planning to get a Cruical M4 128GB for making a custom Fusion Drive.So I shall just stick with my original plan rather than change to M500 120GB?
Thanks : )

I think you would be better off with the M4, if only for it's great firmware support.beginner99 - Tuesday, April 9, 2013 - link
Well kind of a disappointment given the hype. IMHO a small OS drive should be good at random reads / writes while a large drive like the m500 should be good at sequential stuff. A 940 (Pro) would probably offer noticeable better level load times in games and if you don't need 480 GB...Then the high idle power consumption isn't ideal too for laptop use. It's over 3 times higher than the 940. All in all it is a compromise and doesn't invalidate all older ssd's.meacupla - Tuesday, April 9, 2013 - link
You get what you pay for. These are on the cheaper side for SSDs. The fact it uses TLC flash should give you a hint. What is nice about this series is the speed of the 480GB model. Before this, the fastest drives in any series were 240GB models, but now 480GB is also a viable alternative... If you can pay for it.dilidolo - Tuesday, April 9, 2013 - link
Where did you get it's TLC?It's clearly said in the first paragraph it's 128Gbit MLC NAND with 3000 PE.

I don't know either. I must not have had my morning tea.Tjalve - Tuesday, April 9, 2013 - link
Is there a reason for there not being any pictures of the front of the drive? With the controller and the NAND?Kristian Vättö - Tuesday, April 9, 2013 - link
There are some on page 2http://images.anandtech.com/doci/6884/DSC_0093.jpg
