I was reading that sata is a huge bottleneck for a ssd and the pcie is potentially way faster. I currently have a Adata SSD and my computer boots fast but no where near as fast as I would like and I am about to upgrade to either a 500Gb or a 1Tb SSD. So what I'm asking I guess is a pcie SSD noticeably faster, are there any problems that come along with it, and a 1Tb sata ssd costs around $400 and a Pcie around $700-$1,000 so is this price leap worth it? And if it is what would be a good 500Gb and 1Tb SSD to go with?
You can go RAID 0 with SSDs and achieve much faster read/writes, along with saving some cash compared to most PCI-e SSDs.
Anyone use a RAID 0 SSD setup? I can't comment on this first-hand.
I've seen CrystalMark results for Samsung 850 EVOs @ ~500 MB/s read/write with single drives and then close to 1000/900 in RAID 0
why do you need those fast speeds?
Why not? Isn't striving for the best enough reason?
M.2 is a middle-of-the-road solution if your motherboard supports it
Speaking from experience with SAS cards the throughput in the PCIe interface is loads faster than the chipset SATA controllers. I don't use SSDs in my setup (I need the space) but just to give you a baseline I get 200 MB/s sustained in drive-to-drive transfers just by using an LSI SAS 9211 PCIe host bus adapter instead of using my on-board SATA ports.
RAID 0 definitely gets you a serious speed boost if you don't mind the increased risk of data loss due to the nature of RAID 0.
Mushkin makes a PCIe SSD that goes up to 1920 GB and that thing gets some serious throughput with an advertised 2165 MB/s read and 1990 MB/s write. The only one I've seen go faster (feel free to correct me on this) is the Intel Fultondale DC P3700 enterprise SSDs that get 2800 MB/s read and 2000 MB/s write.
I guess the real question is what kind of speeds are you aiming for? The PCIe bus gets you a nice speed boost without having to create any RAID arrays and you can get a Dell PERC H200 card (same as what I have) for ~$75 on Ebay. Each card can take up to eight drives across two breakout cables so if you want absolute maximum possible speed you could get eight SATA SSDs and run them all in RAID 0. I would think that would get you around 3-4, maybe 5 GB/s throughput.
Your budget is also something to consider. Hope this info helps.
Remember if you are getting M.2 that some still transfer at the sata speed limits (6G). make sure its Gen 4 (i believe) I have the kingston predator 480 and I get about 1GB/s speeds. It is overpriced tho (I got it for aesthetics) there are cheaper ones out there by samsung and the like. Now is it worth it? probably not for most people, I got it for productivity and such. Also saves on cables.
So are your saying I can get the PCIE card you listed and use my regular SATA SSD and achieve faster speeds??? If so seems the best route RAID seems like to much of a hassle I don't like losing so much room on the drive either. The PCIE SSD's seem like it's just not cost effective so if there is a middle ground that's where id like to be.
Using a PCIe controller at least gets you better potential throughput. I don't have SSDs hooked up to it nor have I tested them with my card so I couldn't tell you if there's any big noticeable increase. But for the price I can tell you that it's probably the closest to a cost-effective option because you have that much more bandwidth at your disposal and you don't have to shell out for a would-be or actual enterprise grade PCIe SSD. So yes, IMO, the SAS card is the middle ground. Bear in mind of course that the regular SATA SSDs are going to hit their max a lot sooner than M.2 and PCIe, but at least the on-board SATA controller won't be your bottleneck anymore.
I guess it's wort a shot. I have a Sabertooth 990fx MB I don't have a M.2 slot but don't know if I can use an adapter or what.
PCIe SSDs and AMD is flakey last time I heared though.
I was facing the same dilemma myself. Having M.2 connectivity on my MoBo I was thinking it would be a waste not to take advantage of it. But when comparing price and performance for the products available on the market… besides the Samsung SM 951 nothing really seamed worth it.
Don't go with SATA M.2, those work at similar speeds as a good mainstream SATA SSD. Unless you have a micro PC where size is crucial and you have no more free bays, an SSD is a better pick.
Now the real question is if whether that's the drive you need or the drive you want. For my PC usage it's just not profitable to go with a high end M.2 PCIe drive, the money is better spent on a faster CPU. If you do need that kind of speed on a storage device… say if you do video editing for a living, go for it.
Also worth mentioning, you could do just fine with a 512 GB SSD and an HDD. Keeping all your data on an SSD sounds overkill. Stuff like music, watching videos and pictures won't really do much use of it. And do give Intel's Smart Response Technology a look, it might just give what you need.
