Samsung Unveils SSD Delivering Speeds of Over 2 GB/s
- goeric 12y agoHow 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)
- math0ne 12y agoSVN, some people are still stuck using it....
- 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.
- ck2 12y agoHow long until they just use dimm slots?
- jotux 12y agoSATA DIMM slots are already available: http://www.vikingtechnology.com/satadimm-ssd http://www.vikingtechnology.com/satadimm-ssd
- zxexz 12y agoThat only uses the DIMM slot for power - it still uses a SATA connection. This definitely has its uses, though.
- conjecTech 12y agohttp://www.sandisk.com/enterprise/ulltradimm-ssd/ http://www.sandisk.com/enterprise/ulltradimm-ssd/ I think this one meets his description and makes actual use of the DIMM for memory transfer, though I've done relatively little research on it.
- wmf 12y agoHopefully never. Flash's characteristics are so different from DRAM that flash DIMMs just confuse people. But there is http://www.sandisk.com/enterprise/ulltradimm-ssd/ http://www.sandisk.com/enterprise/ulltradimm-ssd/
- pslam 12y agoYou can use the DIMM slot for the DDR bus interface, but not used in the traditional way DRAM would be. The DDR interface is extremely fast, and can be purposed for uses other than the standard row/column/select/precharge etc commands. You would likely need chipset support for it to be used in this fashion, though.
- wmf 12y agoThat's what flash DIMMs do. The problem is that if you stick something in a DIMM slot people expect it to behave like RAM, not like an I/O device.
- dzhiurgis 12y ago> offered in 128GB, 256GB, 512GB, and even 1TB capacities Same as current Apple offering, although Retina MacBook Pro's only supports only 2x link. I hope some larger capacities will become available in next year or two. Also I have noticed no difference in daily computer use when went from 500 MB/s SATA drive to 900 MB/s PCIe.
- mattkirman 12y agoI have a 1TB SSD in my late 2013 15" MacBook Pro Retina and System Information is reporting that it has a 4x link. Even with the additional overhead of having FileVault enabled I still see read/write performance in the region of 1000-1100 MB/s.
- MartynX 12y agoThe 1TB disk in those is PCI-E.
- aduitsis 12y agoActually, it can go to 4x : http://blog.macsales.com/25878-owc-gets-1200mbs-from-ssd-in-2014-macbook-pro-with-retina-display http://blog.macsales.com/25878-owc-gets-1200mbs-from-ssd-in-... They simply plugged in an SSD from a 2013 Mac Pro. Go figure.
- deleted 12y ago[deleted]
- notsony 12y agoBut can they plug in the new Samsung SSD (when available) or any of the PCIe-SSDs currently available on Amazon? My understanding is that Apple (deliberately) changed the physical shape of the PCIe-SSD connector so you could not upgrade the SSD yourself.
- dzhiurgis 12y agoInteresting. EveryMac reports only 2x. I've seen that OWC article where they get up 1200 MB/s and though that might be still achieved by 2x link width.

- WestCoastJustin 12y agoHas a Lenovo part # on it, so I suspect this is the PCIe SSD inside the new ThinkPad X1 released as CES 2015, and there was a nice discussion on HN about it yesterday [1]. In that article, the author mentioned that in the tests "read speeds reached 1350 MB/s", which is pretty freaking awesome for a laptop! Update: Yeah, the SM951 (shown in this article) is in the X1 [2 - see specifications heading].

- JoshTriplett 12y agoThat's amazingly frustrating. I bought the second-generation X1 Carbon last year, on the theory that Lenovo had killed off mouse buttons permanently so there was no sense waiting for a new system that had them; now they release the third-generation X1 that not only has the mouse buttons back, but kills off the insane touch-strip in favor of real function keys again.
- chao- 12y agoI was waiting all of 2013 for that X1 refresh, and spent a whole day swearing at random inanimate objects after seeing what they actually built. Bought an ASUS Zenbook instead. I would LOVE to have somehow lasted this year without a new laptop and sprung for this fixed-up X1, had I known they would correct course. Alas I only buy new laptops every 4-ish years. So Lenovo lost me as a customer for a 7-8 year span because of those asinine touchscreen keys. I loved Thinkpads as reliable Linux workhorses, but the phrase "Will change their usage per app!" might as well say "Will never work in Linux!".
- JoshTriplett 12y agoThe "adaptive" strip actually does work in Linux; hitting the Fn key toggles between F1-F12 and volume/brightness/etc. It's just not fun to use, since it has no tactile response.

- harisamin 12y agowould love to update my 128gb SSD on mid 2011 macbook air :(. Should’ve upgraded to 256 at least …damn you hindsight :)
- wmf 12y agohttp://eshop.macsales.com/shop/SSD/OWC/Air-Retina/Apple-MacBook-Air-2011-Drive-Internal-Flash http://eshop.macsales.com/shop/SSD/OWC/Air-Retina/Apple-MacB...
- bluedino 12y agoYou're better off just finding and OEM 256GB drive on eBay or something. You can use any 2010 or 2011 SSD in the 2011 Air, but the 2012, 2013/2014 Airs are not interchangeable.
- facepalm 12y agoI've upgraded my MB Air to a 1TB SSD from Transcend (JetDrive). I think it works with a mid 2011.
- jfb 12y agoThat's great, but I'd settle for half the speed and twice the density.
- vidarh 12y agoIt usually works the other way with SSDs: The bigger the capacity, the faster. The reason is that to increase capacity they usually add additional flash chips in parallel, so apart from on the very low end it is not unusual to see peak performance double when capacity doubles except where you're limited by the maximum performance of the controller or interface.
- NoMoreNicksLeft 12y agoSpeed's nice, but get the price-per-terabyte down, I beg you.
- cpncrunch 12y agoIt has come down by about 50% in the last year.
- NoMoreNicksLeft 12y agohttp://www.amazon.com/Samsung-2-5-Inch-SATA-Internal-MZ-7TE1T0BW/dp/B00E3W16OU/ http://www.amazon.com/Samsung-2-5-Inch-SATA-Internal-MZ-7TE1... $422. I've been looking at this same one for about a year. It's slightly lower than it was at first, I think it was $470 or so. I need it to be about $100. I'll buy one per month at that price. But at $422 for a terabyte, it's not that useful to me.
- reaperhulk 12y agohttp://camelcamelcamel.com/Samsung-2-5-Inch-SATA-Internal-MZ-7TE1T0BW/product/B00E3W16OU http://camelcamelcamel.com/Samsung-2-5-Inch-SATA-Internal-MZ... Looks like it has dropped less than $100 in the last year, but came down very swiftly in the few months it was on the market before that.
- tw04 12y agoThat one will never get there. This might get close: http://www.newegg.com/Product/Product.aspx?Item=N82E16820147374 http://www.newegg.com/Product/Product.aspx?Item=N82E16820147... But you'll likely have to wait one more generation.
- rasz_pl 12y agoSpeed's nice, price-per-terabyte is important, but do something about endurance and how it acts when it dies. I want my drive to tell me "x and Y is broken, only Z is available, read your data before I die" instead of simply VANISHING from my system on next power up like EVERY FRICKIN SSD does right now (even ones promising read only failure mode like Intel).

- drzaiusapelord 12y agoWhat if we gave up on the idea of fixed disk storage and just filled our computers with enough fast RAM to use as a permanent RAMdisk that wrote to these super fast SSDs on occasion, effectively treating the SSD as a backup for the RAMdisk? With a proper battery backup implemented, I imagine it could work. 2 GBytes/sec is crazy fast. That's my entire steam library in 20 seconds. What percentage of those files change per day? 10% or so at most? So when I shut it off, its syncs up the diff in 2 seconds. When storage gets this fast and RAM this cheap, why bother with fixed disks? Imagine the new Macbook Air with 8gb RAM installed and another 128gb as a RAM disk and a 128gb SSD to back up the RAMdisk.
- frozenport 12y ago>> and just filled our computers with enough fast RAM to use as a permanent RAM disk Current ram implementations use a lot more power compared to an SSD, and might not be suited for a laptop.
- vessenes 12y agoWe have servers like this, and under a surprisingly large number of load scenarios you only get a little speedup. There are use cases where it's helpful, but there are lots of little things that slow down performance that aren't disk-bound, like single-threaded waits for a piece of networking code to timeout, or waits for code that's CPU bound, they all add up. I used to dream of what you're talking about, but from my own experience in the last year, it just doesn't matter that much for the daily experience using a computer. 16GB of RAM is plenty right now, SSDs are very fast for many tasks, I'd look at upgrading your internet bandwidth after that if you want your computer to feel faster.
- seunosewa 12y agoHow is this better than a MacBook Air with 128+8gb of ram and a 128gb super-fast SSD? Why buy a super-fast SSD and only use it for daily backups?
- bobbles 12y agoEnd-game should be that my PC just has 'storage' that ranges from RAM to cloud-based auto-backed up data. The computer should automatically optimise this for commonly used or 'app' style data and keep the information in the level of storage that makes sense.
- monochromatic 12y agoAre there issues with booting from PCIe slots? I assume if there are, they'll get sorted out quickly as drives like this become more popular.
- wtallis 12y agoUnless your system has very buggy firmware, any PCIe lane is as good as any other, even if it's behind a switch. The real difference here that limits compatibility is that the controller uses the NVMe host controller interface and command set, instead of the AHCI standard used by SATA controllers and previous PCIe-based SSDs. Software (firmware or OS) that doesn't have a NVMe driver won't even recognize this drive as being a storage device.

- aruggirello 12y agoThis. Sata Express/M.2 looks promising; there are no mobo's with multiple M.2 ports so far though, so sorry, your 2 GB/s is still not enough for me - a raid0 mdadm device with 4+ very good Sata3 SSD can beat it. OTOH if a mobo with 2 (or more) M.2 ports hits the market, things are probably going to change...
