OCZ Vertex 2 - degrades over time?

post #1 of 45
Thread Starter 
Hi all,

So I was about to get this SSD because of the Sandforce controller but was kinda stumped when I saw both of the reviewers saying that it keeps degrading over time. Are all OCZ SSDs like that? Does that happen to the intel ones too? Just feeling a little in doubt as I like to go over product reviews and stuff before I buy things

Thanks in advance.

Newegg reviewers = n00bs.


All SSD performance degrade when there are not enough clean blocks left. However this has been resolived with TRIM.


The drive supports TRIM..... you have Windows 7.... you have an ICH10R. You are fine.
Once again...

Ugh, i hate it when noobs post incorrect things about stuff they don't understand. Makes the product look bad, and slows the uptake of great tech.

Hmmm okay, so all OCZ Vertex/Agility series support TRIM. What about the firmware, will I lose everything when I need to flash a new update?

You wont loose any data if you update the firmware.

The TRIM kicks in when all the blocks in the NAND Flash have been used,in consequence the performance degrade is insignificant.

The full speed of the SSD can be recovered though,you just need to Secure erase all the blocks.

TRIM cleaning implementation is up to the drive itself. It does not kick in when all blocks are dirty. It is too late by then and performance is already hurting. Most implementations has clean up running whenever the drive is idle for certain period of time.

This is why I don't see why it even matters, it's nice to have TRIM as well (windows 7 generic drivers have it) but even so...3-4 years down the road, you can restore your SSD to "like-new" speeds, as far as I know, you can't do that with mechanical.

AAARgh.

Ok. Depending on the firmware upgrade, you may or may not lose your data. Some updates are 'destructive' some aren't. It will warn you when you download the update.

TRIM kicks in instantly. As soon as you delete something, or empty the recycle bin, the blocks are erased, regardless of if the blocks are full or not. You will notice after you delete a big file, about 5 seconds after its deleted, the HDD light will come on solid for a few seconds (the bigger the file, the longer the light will be on). This is the drive TRIMming itself. This also restores performance to 99.somthing% of new. With TRIM you will never need to secure erase the drive to regain performance.

Yes, from a nand cell life expectancy point of view, it would be better to wait till all the pages in a block are full, but for the sake of performance, the blocks are cleared as soon as the file is deleted. This will only shorten the drive's life by a small amount. Less than 10%. Probably less than 5%.

i flashed my vertex 120 gb to 1.5 firmware honestly wish i never did. 2 months later the drive is now dead on my desk and i cant seem to get a rma through with ocz to get it replaced. most likely i will end up buying a intel and throwing this ocz away due to this problem
