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.

Well, one person in particular had difficulty remembering the proper saying while in Tennessee...Minion4Hire - Tuesday, March 24, 2015 - link
He's quoting George Bush.mapesdhs - Wednesday, March 25, 2015 - link
And hence not exactly a viable rationale for concluding anything about anything.Ian.

Cant beat the Evo on price, performance, or support... so then what is the point?kmmatney - Tuesday, March 24, 2015 - link
None of the benchmarks include the EVO, so it's hard to tell if it beats it or not. It is probably faster, but the MSRP is the same as the 850 Pro, which definitely beats it in most tests.ocztosh - Tuesday, March 24, 2015 - link
Hi CaedenV, thank you for your feedback. The Vector 180 is designed for the high performance/workstation market and is not positioned versus the TLC based EVO. When it comes to best balance of performance/value our ARC series (based on MLC). We will be coming out with future products that push the value envelope that leverage Toshiba TLC.mapesdhs - Wednesday, March 25, 2015 - link
I was impressed with the Arc 100, it was quicker than I expected. Any data yet on returnrates? It would be interesting to know if it's been competitive with the 850 EVO in that regard.
Samsung has a strong reputation here. My main concern with the Vector 180 though is it will
appear too expensive compared to the 850 Pro and SanDisk Extreme Pro.
Ian.

The point is some ppl don't actually want to use TLC.ocztosh - Wednesday, March 25, 2015 - link
Hi chrnochime, thank you for your comments. We so agree there are still a lot of customers that would still prefer MLC. Our current value drive series is MLC based and even after we introduce a TLC based Series we will continue to deliver MLC drives for those customers that are looking for drives higher up the performance spectrum.chrnochime - Tuesday, March 24, 2015 - link
Support? So how long did that TLC fix take to be available again?
