Sequential Read Performance
Our sequential tests are conducted in the same manner as our random IO tests. Each queue depth is tested for three minutes without any idle time in between the tests and the IOs are 4K aligned similar to what you would experience in a typical desktop OS.
Sequential read performance is decent, but it leaves a bit to be desired to match the other high-end SSDs.
Fortunately the power characteristics are still very good despite the slight lack of performance.
The performance at queue depths of 1 and 2 (i.e. the most common ones) leaves room for improvement, but practically every drive is maxing out SATA 6Gbps at QD4 and higher.
Sequential Write Performance
Sequential write testing differs from random testing in the sense that the LBA span is not limited. That's because sequential IOs don't fragment the drive, so the performance will be at its peak regardless.
The Vector 180 doesn't do any better in sequential writes and especially the 960GB model is surprisingly slow. It's quite evident that the Barefoot 3 was never designed with such a large capacity in mind as there is clearly some performance loss due to additional LBA tracking from extra NAND.
This time the power consumption isn't too good either.
While the performance scales pretty nicely, the Vector 180 seems to hit a wall at 500MB/s (450MB/s for the 960GB model). That's pretty far from the 530MB/s that OCZ rates the sequential write at.

Fool me once, shame on, shame on me. A fool me can't get fooled again.I *KNEW* OCZ was a garbage company after all the havoc they caused in the late 90s/early 00s with their crap memory products. It sounded alarm bells in my head that reminded me of their fake address that was literally an empty storefront.
But I read all the press, heard how it was just the same name but a different backing company. So I bought one of their SSDs like a fool, only to send it back multiple times and everytime have it die again. I still have an 80GB intel SSD I bought several years before the OCZ that's still kicking.
After all that, I find out the same crook selling crap memory was behind the "new" OCZ. Pulling his same parlor tricks giving review sites hand-picked models and sending bottom barrel reject flash to customers. You should just refuse to review any more of their hardware, they're crooks and their wares are trash.

Just picked up a Samsung 850 Evo for $204 at Microcenter (price matched to Newegg), last Saturday. Don't understand the justification by OCZ to price the 480GB version at $275.Jahzah_1 - Wednesday, March 25, 2015 - link
That is $204 for the 500GB Evo.mapesdhs - Wednesday, March 25, 2015 - link
As I understand the intent of this product, it's aimed at the likes of the Extreme Proand 850 Pro. The Arc 100 is the mainstream competitor to the EVO, which is $196
on newegg for the 480GB.

oh, I see. What I didn't take into account was the fairly inexpensive nature of 3D-Nand production. So Samsung has an edge it seems, to set their mid-range drives at that price.rocketman122 - Thursday, March 26, 2015 - link
Ive had nothing but bad experience with OCZ. I had mem go bad, rma and sold them. I had the core 64 SSD that the company knew were problematic and still didnt have integrity to not sell them. that core SSD cost me quite chunk of money and I suffered with that. I never forI hope they go out of business and stop selling their gear to the public. we need companies with reliable gear.

Hello rocketman122, thank you for your comments and sorry to hear that you had issues with the Core Series. The old company no longer exists and the IP was purchased by Toshiba. As OCZ Storage Solutions - A Toshiba Group Company we have completely redone our products and processes and there has been a great focus on quality throughout the organization. Everything from the product design cycle through manufacturing has been updated. By implementing our own in-house controller and firmware technology and having access to premium Toshiba NAND we are now able to impact this better than ever. We believe we have a very competitive offering today when it comes to reliability and product quality and hope that we will have the opportunity to prove it to you in the future. Thank you again for your previous business.loimlo - Thursday, March 26, 2015 - link
Good SSD review as usual. Kudos to Kristian's efforts.Btw, I wonder the M-I-A BX100 review. Can we expect it ?

It's coming. This month has been full of NDAs, which have postponed the BX100 review, but once I'm done with next week's NDAs the BX100 will be getting my full attention :)loimlo - Saturday, March 28, 2015 - link
Thanks for clarification. Take your time to do it ~~
