OCZ’s new Vertex shrinks flash and cost.
A while back, we saw OCZ undergo a major restructuring. 150+ product SKUs were removed from their lineup, leaving a solid core group of products for the company to focus on. The Vertex and Agility lines were spared, and the Vector was introduced and well received by the community. With all of that product trimming, we were bound to see another release at some point:
Today we see a branch from one of those tree limbs in the form of the Vertex 3.20. This is basically a Vertex 3, but with the 25nm IMFT Sync flash replaced by newer 20nm IMFT Sync flash. The drop to 20nm comes with a slight penalty in write endurance (3000 cycles, down from the 5000 rating of 25nm) for the gain of cheaper production cost (more dies per 300mm wafer).
IMFT has been cooking up 20nm flash for a while now, and it is becoming mature enough to enter the mainstream. The first entrant was Intel's own 335 Series, which debuted late last year. 20nm flash has no real groundbreaking improvements other than the reduced size, so the hope is that this shrink will translate to lower cost/GB to the end user. Let's see how the new Vertex shakes out.
- Capacity: 120, 240GB
- Sequential read: 550 MB/sec
- Sequential write: 520 MB/sec
- Random read IOPS (up to): 35 k-IOPS
- Random write IOPS (up to): 65 k-IOPS
This simple plastic packaging does away with the 3.5" bracket previously included with all OCZ models.
Very thorough review Allyn.
Very thorough review Allyn. The move to try out the new flash size using sandforce instead of Indilinx perplexed me at first, but then I thought that they would probably want to experiment the hardware change with a tried and true firmware.
looks great nice work Allyn!
looks great nice work Allyn! Though you should really include more 500+ gb units in your reviews for completeness 😀
Thanks! We usually try to
Thanks! We usually try to cover ranges, but the 3.20 is not available in a >240GB capacity.
I am still using my OCZ
I am still using my OCZ Vertex 3 SSD with no problems. Vertex 3.20 does not deserve that Vertex name. Come on, OCZ, you need to do better SSD Vertex SSD products.
What components make up the overhead that prevents SSD’s from reaching the max 6gbps bus speed? Is it all scsi frame overhead or are there other limiting factors?
