cache on these controllers, e.g. the intel, is not used for actually caching reads/writes but rather information for the controller to translate physical location into logical location.
Of course intel uses a more advanced algorithm, thus keeping the write amplification low and getting better random writes, but needing more "cache" to store this information.

The vertex is the first SSD, AFAIK, that actually uses cache memory to cache reads and writes.

Not sure why you say that, there were some SLC who had 32MB of cache.

Corsair S128 which is based on the previous Samsung MLC controller has 32MB of cache.

he is talking about 16 and 256 KILOBYTE of cache, not MEGABYTES of cache... he is saying that they have on controller cache that is used for wear leveling, etc... not for buffering.

I know what he is talking about, but he specifically said that vertex is the first SSD that he recalls that uses cache memory to buffers read/write.

I am just simply pointing out that it is not the first.

ah, I thought you were talking about something else.

Yes. You're right. I hadn't thought of those.
I only wanted to clear up some confusion in the previous posts which talked about the intel drive and the jmicron drives and their use of cache.
