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.

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?
