Yeah, deterioration is to be expected, but I guess I am surprised. Still, to be honest, the read speeds seem to hold up fairly well and for my purposes that's much more important than write speeds. And the amount of stress they put on the drive is much more than I expect to do (write-wise).
Well following SSD for years, I am not surprised it is just how the technology works. That said the sandforce is loads better than the first gen ssd, and almost any ssd will kill a traditional harddrive in speed.
Are they really the same controller? The write speeds for the 64 and 128 GB versions are spec'd much lower than the 256GB. I considered the C300 first because it used sata3 and reads were very fast, but the writes seemed really slow (64GB version).
Is your statement also true for intel? Like the 160GB is faster than, say, the 80GB?
Yes they are really the same controller, larger ssds perform better than smaller ssd. Sometimes by a few small percentage points, sometimes via an order of a magnitude. This has many factors, the number of ram channels for the ssd, the amount of spare area the controller has, the amount of free space the drive knows it has (data that is part of the partition but not used, or has been trimmed), the controller itself, the firmware the controller is using, etc. Each drive has a sweet spot where adding more memory will have very little difference, with the C300 there is a big difference each time you go up a size, an order of magnitude difference in the sequential write.
As for intel there is a huge difference between the 40gb (35 MBps) and the 80gb (70 MBps) in sustained writes but a very small difference between the 80gb (70 MBps), 120gb (100 MBps), and the 160gb (100 MBps).
----------------------------------------
Now while the random and sequential writes get a big boost the bigger the ssd does, the random and sequential reads only get a boost of a few percent. Most people buy an SSD for the reads not the write speed.
If you are using the drive as a OS drive the most important factors are the random reads and random writes for that is what your system is doing the most. After that the most important factor is the sequential reads, the least important thing is the sequential writes. The only time you will benefit from the sequential writes is when you are installing a program or downloading a big file (which if you are doing a desktop is stupid for you should have a SSD for your OS and programs and a traditional HD for everything else due to cost, you can easily move your download folder to the traditional HD.)
The users that are going to benefit from the sequential writes are going to be the people who use the SSD as a swap disk (similar to a ram drive) such as people who are doing workstation and digital design work. That and servers.
So I finally managed to get all the parts for a new computer build (kind of random and rambles)

Sounds like you've done your research. Now I can't wait until I build mine! *NM*
