G1 trim support

Intel, will you ever explain why trim will not be provided for Gen 1 drives? Enthusiasts spend a high premium for new technology that is often problematic and not fully utilisable at first release. Not only do enthusiasts pay a premium they also help iron out teething problems. Now it appears that there is an added price of having support removed.

It just does not make sense to not give trim to gen 1 users and I can imagine that if you are retailer with gen 1 drives it must be hard to shift them.

Is it technically not possible or is it just a short sighted marketing policy?

This year Intel ssd's will no longer be top performers so G1 owners that are unhappy with performance degradation are not likely to get a g2.

From what I understand the only way you are going to get out of the box write performance back is to erase all of the data on every flash chip. To do this you'll have to do a secure erase or something similar.

You will then be forced to reinstall everything back onto the drive (although you maybe able to image the drive back onto it).

IMO it's a bit of a pointless exercise however because once you have turned over 80GB's (or however big the drive is) worth of data, every flash chip will now contain data and you will be back to square one.

Even 'read-erase-write' which is what happens when you attempt to write to a flash chip which already has data on it is quicker than the write speed of a traditional hdd, although that is not the point.

There are two options which I know of which 'may' help. First, CCleaner now has an option to 'wipe free space'. This, apart from taking a long time, will write data to every flash chip which doesnt have data and then erase them all, apart from obv ones with your data on.

Second option is something thats gone around the OCZ forums called Tony Trim. Not an official TRIM command, but it's something they've mackled up over there.

I would do some more research on the OCZ forums on both of these before going any further, as the results are deffinately mixed.

Never ever use CCleaner Wipe Free space on the Gen. 1 Intel MLC, never.. All you do is kill IOPS.. There is only one way to get fresh performance back, make an Image of the Drive, and do an HDDErase. The mostly sequential write done by putting back the Image, will NOT put every Cell in used state, and if it's not a completely full drive (never fill the drive up, for endurance the best is to keep it well below 50%), this will buy you another period with optimal performance. When you first learn to use any Image tool, and how to do an HDDErase, this will be an easy 5min job every 6 month or so (or longer depending on the factors mention above, and the small random writes done by the OS and it's logging, turn off whatever you do not need)... There are many guides out there, to do it right.

Again, never use any Wipe Free Space tool like CCleaner has, only use HDDErase for this job, end of story..

It has been a VERY LONG TIME since the G1 X-25M drives received a firmware update.

When are we going to get the firmware which finally adds TRIM support over RAID?

Thanks
