OCZ has been teasing the Vector 180 for quite some time now. The first hint of the drive was unveiled over nine months ago at Computex 2014 where OCZ displayed a Vector SSD with power loss protection, but the concept of 'full power loss protection for the enterprise segment' as it existed back then never made it to the market. Instead, OCZ decided to partially use the concept and apply it to its new flagship client drive that is also known as the Vector 180.
OCZ calls the power loss protection feature in Vector 180 'Power Failure Management Plus', or PFM+ for short. For cost reasons, OCZ didn't go with full power loss protection similar to enterprise SSDs and hence PFM+ is limited to offering protection for data-at-rest. In other words, PFM+ will protect data that has already been written to the NAND, but any and all user data that still sits in the DRAM buffer waiting to be written will be lost in case of a sudden power loss.
The purpose of PFM+ is to protect the mapping table and reduce the risk of bricking due to a sudden power loss. Since the mapping table is stored in the DRAM for faster access, all SSDs without some sort of power loss protection are inherently vulnerable to mapping table corruption in case of a sudden power loss. In its other SSDs OCZ tries to protect the mapping table by frequently flushing the table from DRAM to NAND, but with higher capacities (like the 960GB) there's more metadata involved and thus more data at risk, which is why OCZ is introducing PFM+ to the Vector 180.
That said, while drive bricking due to mapping table corruption has always been a concern, I don't think it has been significant enough to warrant physical power loss protection for all client SSDs. It makes sense for the Vector 180 given it's high-end focus as professional users are less tolerant to downtime and it also grants OCZ some differentiation in the highly competitive client market.
Aside from PFM+, the other new thing OCZ is bringing to the market with the Vector 180 is a 960GB model. The higher capacity is enabled by the use of 128Gbit NAND, whereas in the past OCZ has only used a 64Gbit die in its products. It seems that Toshiba's switch to 128Gbit die has been rather slow as I have not seen too many products with 128Gbit Toshiba NAND - perhaps there have been some yield issues or maybe Toshiba's partners are just more willing to use the 64Gbit die for performance reasons (you always lose some performance with a higher capacity die due to reduced parallelism).

|Steady-State 4KB Random Write||12K IOPS||20K IOPS||23K IOPS||20K IOPS|

The retail package includes a 3.5" desktop adapter and a license for Acronis True Image HD 2013 cloning software. Like some of OCZ's recent SSDs, the Vector 180 includes a 5-year ShieldPlus Warranty.
OCZ has two flavors of the Barefoot 3 controller and obviously the Vector 180 is using the faster M00 bin, which runs at 397MHz (whereas the M10 as used in the ARC 100 and Vertex 460(a) is clocked at 352MHz).
OCZ's other SSDs have already made the switch to Toshiba's latest A19nm MLC and with the Vector 180 the Vector series is the last one to make that jump. Given that the Vector lineup is OCZ's SATA 6Gbps flagship, it makes sense since NAND endurance and performance tend to increase as the process matures.
The Vector 180 review is the second that is based on our new 2015 SSD Suite and I suggest that you read the introduction article (i.e. the Samsung SM951 review) to get the full details. Due to several NDAs and travel, I unfortunately don't have too many drives as comparison points yet, but I'm running tests non-stop to add more drives for more accurate conclusions.

KAlmquist - Tuesday, March 24, 2015 - linkVector 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.
MrCommunistGen - Tuesday, March 24, 2015 - linkIf 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 - linkTwo 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
Antronman - Wednesday, March 25, 2015 - linkWell 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.
mapesdhs - Wednesday, March 25, 2015 - linkYou'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.
mapesdhs - Wednesday, March 25, 2015 - linkMore than 30 OCZ drives, all working fine. Some had bad luck, others used Marvell ports
and blame OCZ. It varies.
As for coins, well boohoo, not real money unless they're converted back to $.
ocztosh - Monday, March 30, 2015 - linkHi 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 - linkI'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 - linkHello 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 feedback
NeatOman - Wednesday, March 25, 2015 - linkBattery 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.
