SSD reliability statistics


Here are the results of user poll on the SSD reliability that could be useful.

Let us begin with the size statistics.

The picture shows that the most popular formats are 120, 80 and 60, which are released only by Intel.
It is also noticed that the drives with capacity of 120 / 128 are particularly popular among users of alternative operating systems (including OS X).

We have 1587 reports total, divided by brands:

Percentage of returned SSD’s:

SSD’s with issues:

We see the same situation as with the previous picture: Intel and OCZ are at the first place, followed by Crucial. However, OCZ returned rate is almost in three times greater than Intel and Crucial have altogether. In addition, Intel has less percentage of SSD’s with defects.

Further, amount of SSD’s by model:

So far we can draw some conclusions that the Vertex 1 and 2 are not reliable, and Intel X25M G2 are very reliable, according to both charts.

We continue here are the results by the controller.

Here are some specifications:
Samsung S3C29RBB012
Samsung-MAX = Samsung S3C29MAX (used with 470 series)
Toshiba-T6UG1XBG. Used with some drives Kingston (e.g., 100 V)
Indilinx Barefoot used with Vertex 1, etc.
SF-2200 = SandForce SSDs with SATA 6Gb / s
SF-1200 = SandForce SSDs with SATA 3Gb / s
Marvel = C300, M4, and Intel 510
Intel: All Intel SSDs with SATA 3Gb / s

It is interesting that we do not have a lot of results on different controllers, but we can draw the following conclusions.
- Indilinx Barefoot is not reliable very much
- SF-1200 is not too reliable
- SF-2200 is much better, but the number of returns is too big
- Marvel and Intel are relatively reliable

Here are some advice for the buyer.
We have a wide array of SSDs from which to choose, since more companies offer SSDs than standard drives today. However, there is no "best choice".
According to the results, we can conclude: SF 1200, SF 2200 and Indilinx are not recommended to buy. SSDs with controllers from Intel and Marvel, such as Intel X25-M, Intel 320, Intel 510, Crucial C300, Crucial M4, Kingston V 100, 470, and Samsung are recommended to buy. In any case this article is only a guideline for SSDs.

Could you explain in more detail where you got your data from? I'm curious to learn more about this study.
