2010 Value SSD (~$100) Roundup: Kingston and OCZ take on Intel
by Anand Lal Shimpi on June 3, 2010 12:01 AM ESTTRIM Performance
All three of these value drives support TRIM. To gain some insight into how the individual controllers implement TRIM and how they behave in a highly fragmented state I filled the drive with garbage data and then peppered it with random data on top of that for 20 minutes. I then ran HD Tach on the drives and generated the graphs below.
Intel X25-V after Torture
The Intel drive loses a lot of its performance in this highly fragmented case, it does try to restore performance though. The controller is constantly fighting to reorganize fragmented data and restore itself to full performance. TRIMing the garbage data brings performance back to new:

Kingston's drive is surprisingly resilient after our little torture session:

Average read performance drops a bit but average write performance is largely unaffected. A TRIM pass restores read performance to nearly new:

It's not a full restoration however. Kingston doesn't appear to TRIM as aggressively as Intel or most other manufacturers. Thankfully with write performance largely unaffected this doesn't really matter.
OCZ Onyx after Torture
The Onyx's performance after torture looks bad. If you don't have TRIM support in your OS, the Onyx isn't a good choice.

A quick TRIM pass and performance is as good as new on the Onyx.
The best pick here if you don't have TRIM support appears to be Kingston's SSDNow V Series Boot Drive.

Anand,Thanks for using overall performance rather than random read/write to base your conclusions. Your earlier SSD articles slammed the Samsung controller chips pretty hard for the random read/write performance even though their real world performance wasn't too bad.

Just wanted to say "thank you" for each and every one of the SSD articles posted to AnandTech. Your thorough articles make purchasing a SSDs a much safer proposition :-).sparkuss - Thursday, June 3, 2010 - link
Anand,I have been following the TRIM driver issue with my C300-256 SSD on the Crucial forums. Based on the Test Bed chart can I assume you used only the ICH10R port(s). And which OS driver was used? The MSAHCI or the INTEL IMSM?
Thank You

I understand the significance of the TRIM test that was performed....BUT...how realistic is this test. I'd be interested in seeing how well the TRIM and Garbage Collection functionality of the firmware work if, say, half of the drive endured a similar loading. OR, run the same units idle for 100hrs (yeah, ridiculous, just like the test) and see how much things have recovered.In the grand scheme of things, benchmarks are great for marketing. They do offer some credence in the fact that they offer a side by side comparison of various components under certain lab conditions. But the problem is, they do not often reflect real world usage performance. Or, more importantly, real world tangible differences in performance.

I can assure you, that these benchmarks to simulate TRIM aren't that far away from reality. On a small drive, you will see such crappy performance after several weeks, depending on your usage. I experienced this on the Indilinxdrives when they didn't have TRIM and better GC. 3 Weeks and my write was down to 35MB/s.Of course it depends, as I said, highly on your usage pattern. If you don't use it (idle, what a test?!?!), it won't affect the performance. Why should it...

I'm not proposing anything that extreme, but I would like to see Garbage Collection tested on a TRIM-less OS. Something similar to the TRIM test used now, but ran under Vista/XP or Windows 7 with TRIM commands disabled and the drives left idle over night. OCZ has touted their aggressive Garbage Collection, while Intel just says it's there. It would be nice to have an actual measurement of their effectiveness. Especially in a budget review where these drives would likely be used as upgrades for older Vista desktops or netbooks running XP.rocky12345 - Thursday, June 3, 2010 - link
It was a good review/article but non of those drives are worth what you pay for them. They simply are way to small to be of any good to anyone. Also as a gaming drive 30GB or 40GB really!! Maybe back in 1999 that would float every ones boat but in this day & age 40GB just does not cut it & for the price a 1 or 2TB HDD is well worth the 7 or 8 seconds it takes longer to load a game. I do see SSD being a good thing someday but at this point if you have to give up your left nut to get one that is a good size then it is not worth it at all.

If you haven't used one on your primary computer, then you really don't know what you're talking about. Buy and use one for a week or two (it won't take that long) and then go back to your slow-as-molasses hard drive. You'll feel like you're back in 1989 while you wait and wait and wait for your hard drive to access data.rocky12345 - Friday, June 4, 2010 - link
slow hard drive yea ok. I happen to have 2 sets of raid arrays in my system 4 in each set. first set is Seagate 1TB 7200.12 4 in total second set is Seagate Barracuda® XT 2TB 4 in total. So trust me I am not missing anything as you stated I have more than enough speed & most importantly I have the space my work requires me to have a SSD at this point can not give me the needed space at the same price point. ys the SSD drives are fast they just need to make them bigger & cheaper until then they are a niche product..Nataku - Friday, June 4, 2010 - link
I hate to say this... but you really should try before going off like that... X25 felt way faster than the RAID0 I've encountered over the years
