Any SSD's have SF-2500-like performance degradation prevention?

post #1 of 8
Thread Starter 
I am really impressed by OCZ's Vertex 3. The Article doesn't seem to touch on this much, but it is HUGE that the drive seems to no longer require TRIM commands. See the following link:
http://www.anandtech.com/show/4159/o...t-sf2500-ssd/6

This means I can use it in my server without worry, which is running Server 2008 (not R2) and doesn't have TRIM support. However, the Vertex 3 is still a couple of months out, and I don't have that kind of time to wait for it.

Are there any SSD's out there that do not require the TRIM command to maintain performance? Or at least do not suffer as much as another typical SSD?

Alternatively, are there any comprehensive benchmarks showing SSD "dirty" performance?

What are you using your server for? The issue with the SandForce is a specific scenario that most will not encounter.

Current SandForce, Indilinx, and Marvell controllers all have garbage collection.

In general, you want TRIM. The SSD knows what to clean rather than having to try and figure it out.

It's a Minecraft server... I was talking about using a Ramdisk instead, since the maps for Minecraft were stored in 4KB files, but an update coming out next week will change the map storage to 4MB chunks, thus alleviating the extremely quick wear I was experiencing on MLC SSDs.

The other issue with using SSD's though, is the lack of TRIM support on my OS. I don't have $600 to buy R2, so my only option is to try and find an SSD that has the least performance degradation from having dirty pages. Or go with the ramdisk. But the ramdisk is extremely expensive compared to MLC SSDs - I'd almost rather buy 4 SSD's and RAID0 them than buy a single 12GB Ramdisk. Ideally though, I don't really want to have to run RAID at all to get acceptable performance.

Does the original Vertex drive have built-in garbage collection (it's the drive I am currently using in the server)? How much better is a Vertex 2 at garbage collection and preventing performance degradation vs the original Vertex? Are any other drives better?

Which of the current controllers have the best garbage collection available? I'm digging the SF-2500, but obviously, can't get that yet. So what's the next-best thing?

Also, why is the issue with the SF a specific scenario? As far as I could tell, the reviewer tested several situations where a user might experience a "dirty" drive from having deleted files without TRIM, but the performance remains the same.

No edu email here...

Regardless, the heart of my question is, what is the best recommendation for an SSD that will still perform well "used" or "dirty" without TRIM support by the OS?

honestly C300s can survive without TRIM command as well.

Thanks for the input Sin. The C300's look like decent enough drives.

A new phrase came up during a discussion I am having on the OCZ forums about this same issue. Panic lock. What does it mean, what causes it, and what performance degradation is seen from it?

Actually Sin, I think you're wrong about that. The C300 seems to have major problems with bunches of random writes going untrimmed.
See this article: http://www.anandtech.com/show/3812/t...realssd-c300/8

The Sandforce controller performs much better in said test, and said test is as close as I can find for a benchmark for the type of activity I am looking at here.
