just a heads up to anyone considering using a OCZ Agility series drive:

i just RMA'd my second one today. they work for a few days then i get a beachball of death followed by unreadable drive on reboot. After this happens no amount of disk utility handywork can revive it and i get "bad node found" errors.

OCZ suggested today that the drive may not be mac compatible. i doubt this since it installs fine and runs perfect for a short while.

I will say OCZ has been great about replacing them thus far but i am growing tired of working on it.

I just bought the Corsair x256 256gb SSD (~$460 AR + cashback) so we'll see how it is when i get it soon in the mail.

I was really going to wait for the G2 Intel SSds but couldn't pass up the deal.

hopefully with the slower random access, I won't notice a difference. Then again, this is my first SSD so i'll probably be amazed anyways.

Can you post some experience / comments so far with the drive? Performance numbers / benchmarks would be great too. But overall, how do you like it so far? Fast? And has it been reliable.

You got a pretty good deal on that drive!

What program is used to test the speed of the SSDs here?

Also, OCZ (at least Vertex, Agility and Summit) have 3 years warranty.

I use xBench.

I already have saved up for an Intel, but I am still continuing the savings. I want the big 256GB SLC drive if I can get my hands on it, else I'll go with the 300GB MLC.

first one died running 10.5.8

second one died on snow leopard

as far as hardware its a late 2008 unibody MBP 2.4C2D 4gb ram.

I think maybe it's SSD compatibility. I would say getting an Intel drive 80GB. I mean, less storage space, but you get a drive known for reliability and compatibility with OS X.

allready ordered the intel 80GB G2C1 drive :)
the OCZ is a fine drive and very fast, but yes i am afraid may not be the best for OSX installs.

i ordered the same thing for the same reason. Less space but I dont have to worry about anything. I am sure there are many with Vertex SSD's that are fine but I have yet to see, hear, read one issue with the Intel drives (well besides the cost).

Can somebody tell me about trim support?
Is it a hardware matter or something that the operating system should do?
Does mac os x has trim support?

TRIM is basically a command to help out with SSD write problems once the drive is becoming full or when the drive was full erased (due to the dynamics of how SSD NAND flash works) and needs to be written again with new data.

Yes, it is hardware dependent according to Intel. Only G2 drives from them carry the support. All G1 models won't.

In terms of OS support, Snow Leopard doesn't have TRIM support. Windows 7 does.

So it all about credibility and data safety. As I can understand it is both hardware and software matter, this trim support.

So, is it a bad idea for mac users to use such ssd disks? Better waiting for future osx support of trim technology?

Hi there, I'd like to test my SSD and add its scores to this thread.

Can I ask what programme was used for the Random 4k read and writes?

I have an Intel X18M

Its flippin FAAAAAAAAAAAAAST
