Admittedly they're not bad, but after the 840 EVO catastrophe i'm not particularly enthused with Samsung.Hilarious! This thread was fun to read. Why? Because we've hashed all this stuff out years ago..and somehow some people still don't get the memo, show up here, and then try to tell us how stuff like Samsung is better.
But reliability with storing data that is... lacking. ;)Samsung being able to make their own controller and fabricate the NAND gives them a large advantage over many others. Good power usage, excellent performance, great pricing...
Depends. Some of the high end SSD's chew as much as a laptop drive.And who cares about power usage! Whatever SSD you are using is going to use far less power than spinning disks anyway.
I probably wouldn't have noticed. Besides, at a couple of watts we're talking something pretty inconsequential. If you're really concerned about power and/or heat generation, that's probably your primary attribute for choosing what media to use. ;)Depends.

Yeah, I've been experimenting with 2TB 2.5" laptop drives on the VM storage filer here and while not totally awesome I am reasonably happy. If I could justify the cost of ~4X to move that to 1TB SSD's I'm sure it'd be even more zippy. Seen it pushing 9+Gbps on dual 10Gbps as iSCSI datastore doing I/O in a single VM...I probably wouldn't have noticed. Besides, at a couple of watts we're talking something pretty inconsequential.

I hadn't noticed anything that bad in awhile but it's certainly believable.The "high-end" SSDs can still chew 25W each.
25 watts? is that a typo? That's like.. multiple desktop drives.The "high-end" SSDs can still chew 25W each.
The new P3700 2TB eats 25W at full blast ... but outside of the NVMe space pretty much everything is <10W if not <5W.25 watts? is that a typo? That's like.. multiple desktop drives.
Well, going forward, we'll be seeing NVMe SSDs both in the PCI-e card format and the 2.5" format, so it's going to have to be fixed/worked around one way or another.Sure, but I don't consider NVMe cards to be "SSDs" in the traditional sense. A 25W SSD would likely burn up in no time because of the heat generation and relatively low heat transfer surface area.
Admittedly that is with regards to consumer, not enterprise loads. For enterprise loads you wouldn't even want to consider the EVOs as they lack power loss protections.But reliability with storing data that is... lacking. ;)

For me, performance is important, but not as important as reliability. Something the EVO's have/are having major problems with.
Newer Sammy/Sandisk drives will chomp less than a laptop drive. <5w a piece. Efficiency given their speed also makes them massively advantageous from a power usage perspective. Slap an SSD into an old laptop, you'll actually notice a battery life improvement.Depends. Some of the high end SSD's chew as much as a laptop drive.
Doubtful, NVMe for SATA3 is a complete waste. M.2/PCIe or bust. SATA3 is a bottleneck for the higher end SSDs on the market. Perhaps for cheapo SSDs...Well, going forward, we'll be seeing NVMe SSDs both in the PCI-e card format and the 2.5" format, so it's going to have to be fixed/worked around one way or another.
Those Intel enterprise SSDs come with fairly large heatsinks to dissipate all that heat. So not a big issue.Sure, but I don't consider NVMe cards to be "SSDs" in the traditional sense. A 25W SSD would likely burn up in no time because of the heat generation and relatively low heat transfer surface area.
NVMe drives actually are MORE efficient than normal SSDs. Apple purchased a company working on SSD controllers and had them design the NVMe controller utilized in the new Macbook's PCIe SSD.The new P3700 2TB eats 25W at full blast ... but outside of the NVMe space pretty much everything is <10W if not <5W.
NVMe has nothing to do with SATA.Doubtful, NVMe for SATA3 is a complete waste. M.2/PCIe or bust. SATA3 is a bottleneck for the higher end SSDs on the market. Perhaps for cheapo SSDs...
That depends on what your use case is. I certainly have enterprise loads where the EVO's would be perfect. Lots of random read, modest amounts of write, no major crisis in the rare case where something gets lost.Admittedly that is with regards to consumer, not enterprise loads. For enterprise loads you wouldn't even want to consider the EVOs as they lack power loss protections.
Yes, but we weren't really talking about that. The point is that SSD can sometimes consume more than HDD. Again, it is sensitive to what your use case is. I'd love to cram a bunch of SSD's into our new filer but making the project 3x-4x the cost is just a total nonstarter.Newer Sammy/Sandisk drives will chomp less than a laptop drive. <5w a piece.

I don't know. I'm not sure how you'd stick 24 PCIe NVMe drives into a 2U server. I do know you could fit them in as 2.5" units.Doubtful, NVMe for SATA3 is a complete waste. M.2/PCIe or bust.
The SATA Express abomination?NVMe has nothing to do with SATA.
2.5" NVMe drives use a PCI-e connection over a new (or is it the SAS3?) connector/cable system. All signalling is PCI-e (the logical layer could be AHCI, but that is silly, so NVMe is the standard).
Good point, enterprise will still want storage density, though i've been focusing on consumer and enterprise in a really flipflop manner.That depends on what your use case is. I certainly have enterprise loads where the EVO's would be perfect. Lots of random read, modest amounts of write, no major crisis in the rare case where something gets lost.
Mmmm, cheaper Enterprise SSDs equivical to 850 EVOs are upon us. Read-centric drives.

No, it's a completely different connector/cable system, SFF-8639.The SATA Express abomination?
