no idea lol maybe you should find that out

well ok. between the two i still think intel 530 is of better value. still, it's up to you

well yeah that's one way to make up your mind if you want to

yeah weird. i still think ssd's are expensive, so it's good to have longer warranty.

yeah it depends on how you use yours. for general use, it's not easy.

hm weird.. not familiar with amd systems.

yeah price is definitely samsung's advantage if you're talking about common sata/msata variants. however it's not just that. what surprised me was the adoption of pci-e x4 m.2 ssd's in asus g-series released recently (especially g751, g771). by the way, asus's implementations with these m.2 ssd's are by far the better one (i.e. m.2 bracket serves 2 purposes: as a placeholder, and as a heat spreader)

haha right we were all affected by the slow read bug in 840 evo. after the update that bug seemed to be gone. just now i checked the read speeds of my 840 evo and they were good. will do tests again after a few weeks.

i have no idea about asus' sata-e drive. imo sata-e will not gain popularity very soon. it is too bulky.

yeah will post an update here same here everything is good:

samsung 840 evo, 500gb sata:


samsung 840 evo, 500gb msata:


edit: as comparisons, here are the results of samsung sm841, and crucial m500.

samsung sm841, 512gb sata:


crucial m500, 960gb sata:

oh this one. yeah looks are all good. it's like msi super raid2 in their high-end laptops.

previously i waited for their pci-e adapter kit for m.2 ssd. unfortunately it took like forever so i just went for bplus :/

hopefully it's not a teaser.

yeah to me it's an enclosure with a raid card inside it. because of compact form factors, we can put msata or m.2 ssd's inside. (i think it can at least take up to 3x full-size msata) 2x 128gb should be minimum. max maybe 3x 1tb? (if 3x ports are provided. the bottleneck might be the total bandwidth supported by sata-e if it's nvme hehehe)

i think it does no harm to ssd. (it's just normal raid 0) as long as trim is supported performance should be good.

crucial mx100 is below 1k.

the overheads are imminent. yeah imo for general use it's a waste. putting aside work purposes, i can hardly hit the limit of a single ssd.

oh. viewnet@899?

edit: update - jayacom@858.

whoah.. that's the lowest so far, even with shipping the price is still good.

update: plextor m5pro xtreme new firmware, 1.08.

2014/10/28 This firmware revision improves:

1. Potential problem which might make system hanged.
2. 4K Random write consistency.
3. GC execution flow for dealing host command.

hm.. maybe it's only me, i think the system is snappier after applying this.

In a year or two hopefully sata ssd can reach a price point that is much more affordable to most people.

For the next coming wave i hope laptops that i want will have at least 1x pcie 3.0 x4 m.2 slot. (Like asus g-series g751, g771) Unlike desktops, the pcie lanes in laptop chips/cpu are limited. Hopefully that will change in near future. By the look at the current chips, if you go for gpu sli config (like aw18), the m.2 slot will very likely be pcie x2 only. (The 2x gpu have taken up 16 pcie lanes)

The best bet is still laptops with single gpu.

ok story time

technically, to get rid of bottlenecks by sata's bandwidth limitation, pci-e is used to provide more bandwidth to ssd so that it can run much faster in a system. commercially, most people thought pci-e 2.0 x2 is good enough for the market. (so that they can earn more money before releasing more powerful versions, i.e. from pci-e 2.0 x2 to 2.0 x4, then 3.0 x2, finally 3.0 x4. you know the drill)

however, two companies thought otherwise.

the first one was samsung. instead of following the norm, they released xp941, a pci-e 2.0 x4 m.2 ssd to oem in year 2013 (that's the first pci-e consumer-centric ssd). with that move samsung was forcing everyone to change their game plans, including totally skipped pci-e x2 to be at least competitive. initially there were not much enthusiasm among these oem. until the second company reacted. a few months ago, asrock put an ultra m.2 slot (1x pci-e 3.0 x4) in their product lineup, the extreme series. back then, those were the only mobo that provides such a m.2 slot. on top of that, despite this premium feature, they sold them cheap. that move made asrock to suddenly become one of the best recognized mobo manufacturers almost everywhere, and their products were recommended and awarded in macam-macam best awards.

all the above happened in a year. see? these companies really can make a difference if they want to.

now the market is populated with compatible slots. (desktop mobo's, laptops) this year samsung did it again to complete the whole story. this time they announced sm951, the first consumer-centric pci-e 3.0 x4 nvme ssd. (sm953 is for enterprise) maybe we can get hold some of these beasty ssd sometimes next year

edit: this was one of the reasons why i got a lot of samsung drives. (more than 10 hehe) i am not their affiliate, or fan boy, or whatever you wanna call it. i just wanna support companies like this to make a difference in the development of better ssd's. (only ssd. the rest i am not that keen hehehe)

pcie is computer bus, m.2 is a standard for a physical component (including size, form factors) and connectors (including key type, slot) that i think replacing msata, and nvme is the specification to access ssd via pcie.

in terms of speed, both should be the same if the slots provide the same bandwidth (same pcie version). (it depends on ssd capability also)

imo the second one will be more flexible if you have a desktop computer. you can provide bandwidth up to pci-e 3.0 x16 to the ssd. (at least for now. currently in enterprise landscape i think we are going to have pci-e 3.0 x8 ssd)

small form factor storage like this are necessary, since these days everything is going slimmer, and the trend of storage is moving towards nas/cloud. (think aio desktops)

yes for current implementations m.2 and pci-e slot share the same pci-e lanes. for normal users, i think there is no need for most of us to worry about this lane sharing thing. it's sufficient for general use. for instance, i can set up my desktop to have dual-gpu sli/cfx, and run 1x pci-e ssd at the same time, with no conflicts.

wildwestgoh knows where to get ready stocks for you (however i think intel 730 is pricey, no?)

i did suggest you several choices previously. (samsung 850 pro, plextor m6pro, and crucial m550) those are imo the better ones that fit your budgets as of now.

maybe others can help you better if you describe what you have done to set it up accordingly. did you set the sata mode in bios to ahci? did you reinstall a fresh OS after that? what do you mean by "normal sata port instead of sata iii"?

i have checked the manual of your mobo it seems that it has no sata iii ports. all are sata ii. from a brief search most people suggested that you connect the ssd to the blue ports.

very sorry because i have no idea what i'm talking about regarding your mobo. maybe you need to check with chinkw1 about this port thing.

normally what we do are quite simple:
1. make sure sata configuration for the ssd is set to ahci in bios first;
2. install a fresh copy of windows.

that's it.

it's correct sata2 runs slower, but i think it's still much faster than hdd.

oh ok thanks for the clarifications what confused me was that according to the manual that mobo has only sata2 ports. (intel and jmicron)

asus manual qc tak pass :/

haha! i think the slow read bug of 840 evo has been fixed for good after the firmware and performance restore. (there was a newer 1.1 however it will not work if you have applied 1.0) so far everything is fine here. still i wanna do a few test in 3 weeks.

i was always curious about their response time from identifying problem to releasing proper fix when there is a problem in their products. this round it turned out to be not bad, compared to many previous cases that involved other brands (for those who owned the affected ssd's previously, they know what happened)

i have tested a number of samsung drives, from consumer to enterprise. i think they did a good job in making the ssd's despite their rapid release cycles. (apart from 840 evo, none of their retail and oem drives have issues)

for this part it's better for you to check out the mobo manual. normally in the manual there are sections that explain and highlight what to or not to do with these pci-e slots.

right. it's better to check out the manual carefully first for potential conflicts when you plan for your new rig/upgrade.
