AnandTech Storage Bench - Light
The Light trace is designed to be an accurate illustration of basic usage. It's basically a subset of the Heavy trace, but we've left out some workloads to reduce the writes and make it more read intensive in general.
| AnandTech Storage Bench - Light - Specs | ||||||||||||
| Reads | 372,630 | |||||||||||
| Writes | 459,709 | |||||||||||
| Total IO Operations | 832,339 | |||||||||||
| Total GB Read | 17.97 GB | |||||||||||
| Total GB Written | 23.25 GB | |||||||||||
| Average Queue Depth | ~4.6 | |||||||||||
| Focus | Basic, light IO usage | |||||||||||
The Light trace still has more writes than reads, but a very light workload would be even more read-centric (think web browsing, document editing, etc). It has about 23GB of writes, which would account for roughly two or three days of average usage (i.e. 7-11GB per day).
| AnandTech Storage Bench - Light - IO Breakdown | |||||||||||
| IO Size | <4KB | 4KB | 8KB | 16KB | 32KB | 64KB | 128KB | ||||
| % of Total | 6.2% | 27.6% | 2.4% | 8.0% | 6.5% | 4.8% | 26.4% | ||||
The IO distribution of the Light trace is very similar to the Heavy trace with slightly more IOs being 128KB. About 70% of the IOs are sequential, though, so that is a major difference compared to the Heavy trace.
| AnandTech Storage Bench - Light - QD Breakdown | ||||||||||||
| Queue Depth | 1 | 2 | 3 | 4-5 | 6-10 | 11-20 | 21-32 | >32 | ||||
| % of Total | 73.4% | 16.8% | 2.6% | 2.3% | 3.1% | 1.5% | 0.2% | 0.2% | ||||
Over 90% of the IOs have a queue depth of one or two, which further proves the importance of low queue depth performance.
The Barefoot 3's focus has always been sustained rather than peak performance and that's visible in our Light trace. It's not slow by any means since most drives are within a 10% margin (excluding the 850 Pro and Neutron XT), though.
The same applies to latency where most drives are essentially on par with each other.
While the 850 Pro does very well when it comes to performance, it's also the most power hungry, whereas the Vector 180 at smaller capacities is again easily the most power efficient drive.

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.
