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.

Vector 180 vx. MX 100:I think that the Crucial MX 100 will be a bit faster than the Vector 180 under typical usage, though the Vector 180 does outperform the MX 100 on some benchmarks. Both drives have partial power loss protection. The Vector 180 has a 5 year warranty vs. the 3 year warranty on the MX 100, but a lot of people will be looking to upgrade from SATA to PCIe SSD's before the 3 year warranty expires. In short, I don't see any reason to pay a premium price for the Vector 180.

If only HIPM+DIPM worked (yes I know its a hardware limitation of the platform) this looks like it'd be a great laptop SSD due to such low power consumption in the various workloads measured here.djsvetljo - Tuesday, March 24, 2015 - link
Two dead OCZ drives - there will never be a 3rd one. One of the drives was from the era of the bitcoins boom ( when they were easy to mine). Lost 150 coins there ( that's over $50 000). They stupid thing locked up due to power issues ( too many power cycles).STAY AWAY FROM OCZ

Well the thing is, the internals are drastically different right now.I've been in the market for a good SSD for a while. These drives seem to perform well. Sadly outperformed by the 850 Pro drives, but I do think that the enclosure is actually very aesthetically pleasing. If the cost could be driven down a lot, I'd be very interested in the 180.

You're right, they need to have a price advantage with the 180 to pull people in. Also,availability needs to be good - in the past it's been rather sketchy with the 150, which
means prices tend to creep up from a small number of suppliers.

More than 30 OCZ drives, all working fine. Some had bad luck, others used Marvell portsand blame OCZ. It varies.
As for coins, well boohoo, not real money unless they're converted back to $.

Hi mapesdhs, thank you for your feedback and great to hear the drives are working well for you. We greatly appreciate both your business and support.FalcomPSX - Tuesday, March 24, 2015 - link
I've owned i think three OCZ drives in the past, they've all bricked on me within about a year. Never again will I purchase their shoddy products. While i was able to get warranty replacments each time, and the customer service is decent, the product itself is just not reliable in any way. I don't know if the new ones are improved at all, but i'm not risking MY data to find out.ocztosh - Wednesday, March 25, 2015 - link
Hello FalcomPSX, thank you for your comments and sorry to hear that you has a problem with previous drives. We are a new organization under Toshiba and have made significant changes to everything from processes to production. We understand how you feel and hope that one day we will have the opportunity to demonstrate the reliability of our current products. Thank you again for your feedbackNeatOman - Wednesday, March 25, 2015 - link
Battery backup should be built into the PSU for workstations and servers, google does this for their data centers.. why shouldn't servers and workstations. All you need is 1 minute for the average workstation to go into hibernation until power is back on IMO.
