OCZ Gets Clever: Agility vs. Vertex, Even Cheaper Indilinx SSDs
Samsung makes SSDs for OEMs, Samsung sells pre-made SSDs to companies like OCZ and Corsair and Samsung also makes NAND flash. Samsung actually made all of the flash that was used in the first generation of Indilinx SSDs. Unfortunately, prices went up.
OCZ was quick to adapt and started making Indilinx drives using flash from different manufacturers. This is the OCZ Vertex, we’re all familiar with it:
This is the OCZ Agility. You get the same controller as the Vertex, but with either Intel 50nm or Toshiba 40nm flash:
My Vertex used Samsung flash, like all other Indilinx drives
My Agility used Intel's 50nm flash
Some lucky Agility owners get Toshiba 40nm flash, which is faster.
The performance is a lower since the flash chips themselves are slower. I'm actually comparing the Vertex Turbo here but my Turbo sample actually runs as fast as most stock Indilinx MLC drives so it provides good reference for an Agility vs. a good Vertex drive:
| Used Performance | OCZ Agility | OCZ Vertex | Vertex Advantage |
| 4KB Random Write | 7.1 MB/s | 7.6 MB/s | 7% |
| 4KB Random Read | 35.9 MB/s | 37.4 MB/s | 4.2% |
| 2MB Sequential Write | 136.3 MB/s | 155.8 MB/s | 14.3% |
| 2MB Sequential Read | 241.3 MB/s | 254.2 MB/s | 5.3% |
| PCMark Vantage Overall | 14468 | 14694 | 1.6% |
| PCMark Vantage HDD | 24293 | 25309 | 4.2% |
The performance ranges from 0 - 5% in the PCMark suite and jumps up to 4 - 14% in the low level tests. The price difference amounts to around 12% for a 128GB drive and 9.5% for a 64GB drive. There's no 256GB Agility.
| OCZ Agility | OCZ Vertex | Price Difference | |
| 64GB | $199.00 | $219.00 | $19 |
| 128GB | $329.00 | $369.00 | $40 |
| 256GB | N/A | $725.00 | N/A |
If you want to make the jump to an SSD and are looking to save every last dollar, the Agility is an option.
I think the Agility line is a great idea from OCZ. I’m not sure about you but personally, as long as the flash is reliable, I don’t care who makes it. And I’m willing to give up a little in the way of performance in order to hit more competitive price points.

Been over a year since this article was published...still very relevant. Any plans to update it with the latest products/drivers/firmware? There have been some significant updates, and it would be good to at least have updated comparisons.Well done, more more more!

Excellent article but you left out sandforce. I'm curious if this was an oversight or a purposeful moission.PHT - Friday, September 28, 2012 - link
This article is fantastic, the best I ever read about SSD.Any follow up with new SATA III drives and new controllers like SandForce, new Indilinx etc.?
I will be glad to see it.

Hello everyone.This post is quite old but I hope someone can answer.
I am concerned about the life of my ssd (sandisk extreme 240). I performed partitions ignoring the issue of the level of wear and partitions. I have it for one year ago with a 30gb partition and one with 200GB. I wanted to use large drive for data but I did not have time for that and just use the first 30gb partition . My question is if the ssd may be damaged by using only a little segment. DiskInfo shows 10tb reading 18 tb and writing.
sorry my poor English.
Thanks for any help.

Hey,This is the most informative article i have ever read.Can You Please clear Out Some Of my Doubts:-1.Does Playing Video Games or Running Programs add to Writing on the SSD
2.Is 1 Write Cycle=Filling 120GB of SSD once
3.I really write on my HDD a lot(Seriusly a Lot) So how much life cycle can i expect from Samsung 840 SSD(Neither Pro nor EVO) I mean for how much time can i expect it to be writable
Please Help me cause i want the speeds of SSD but i want it to last for me too
Thanks,
Ojaswin
