How does this compare to the PCI-e based SSD's in the Mac Pro?
- wmf 12y agoIt's a newer model. I suspect the difference is negligible in real-world usage.
- Someone1234 12y agoTwice the maximum speed is "negligible?" Hmm. Certainly at sequential tasks it should be marked, maybe not so much in random.
- wmf 12y agoBesides copying large files, do you have an app that can consume 2 GB/s? That's more than two streams of uncompressed 4K.
- valarauca1 12y agoAs its transfer speed yes I do. I don't have to move 10GB+ files to know if my network is 10MB/100MB/1000MB/10G0B. The speed it transfers is representative of my network speed be that file 4k, 10MB, or 100GB. The same is true for all transfer speeds. :.:.: Also yes there are diminishing returns with information requests, acks, etc.
- kansface 12y agoUpgrading to Mavericks comes to mind.
- micro-ram 12y agoAd-hoc connecting new Macs over Thunderbolt 2 at 20Gbits/sec is very nice! My MacBook Pro and Mac Pro share their 1TB SSD drives between each other via TB2.
- JoshTriplett 12y ago"git grep" on a large source tree. (Or, for that matter, "repo grep" on a whole family of git repositories.)
- foone 12y agoYeah, one of my main debugging tasks right now is primarily limited by my SSD write speed. Instruction-level traces take 9gb at minimum, any more significant work takes quite a lot more.
- dman 12y agoHow are you generating the instruction traces? What format are you writing them to on disk?
- foone 12y agoOllydbg run traces and in a plain text format. I'm constrained by my target application only working on older versions of windows, so I can't easily insert a compression step in the log generation or switch to a more compact binary representation. (I'm currently looking into solutions like a custom filesystem driver, running a second VM and using internal networking to stream to a FUSE filesystem, or possibly even hooking the filesystem access of my debugger and inserting a compression step into WriteFile() calls)

- bitL 12y agoUncompressed 16-bit 16K for mastering high-quality 4K content? It is thought 8K will be the final TV resolution - for that you'd need 32K for a good quality output - I guess even current DDR3 would be too slow, not mentioning SSDs.
- vidarh 12y agoTry working with map data, where having layers that consumes tens of GB, and having hundreds of layers, is not that unusual. Load that into a database, and watch the size blow up even further thanks to indexes etc. There are plenty of applications that are still disk IO constrained at those speeds.
- gilgoomesh 12y agoIt looks like the real-world read speed of 1362MB/s http://www.thinkscopes.com/blog/2015/01/06/lenovo-thinkpad-x1-carbon-gen-3-review-2/ http://www.thinkscopes.com/blog/2015/01/06/lenovo-thinkpad-x... is only around 10% more than the 1184MB/s speed of the 2013 Mac Pro: http://macperformanceguide.com/MacPro2013-performance-SSD.html http://macperformanceguide.com/MacPro2013-performance-SSD.ht...
- dzhiurgis 12y agoPCIe on Mac Pro has 4x link, although in AnandTech's benchmark they achieved ~1GB/s read speed on 512GB stick. So I assume theoretically one would see speed increase.
