I do run a number of VMware Workstation VMs off it (some running nearly fulltime; others periodically). They are lightning fast. That said; if it weren't my primary desktop (I have a few lab servers as well), I'd have a hard time advocating for it as a worthwhile expense. I was only able to justify it between selling off the Star Citizen code on eBay + writing off the card as a business expense. It's slick as poo poo; but its in direct conflict with the 80/20 rule and something I'd be somewhat hesitant to recommend unless you make money on the computer, have a direct need for this sort of performance, and/or convince someone else to cover the cost.

I have a 900p. I will not be buying more. There is no benefit over a DC P4500 (or higher series, per your estimated drive writes per day) except on artificially crafted benchmarks with no queue depth. It's not better for my oracle dbs, not better for my vdi environment, not better for even a client hpc environment. Simply by the nature of being a storage drop in replacement, optane will always be crippled. Imo, we have effectively licked classical local block storage by placing it on the pcie bus and on the infinitely-scalable nvme protocol (and making it securely available by direct network fabric access). It's the 2H 2018 DIMM 3DXpoint that's going to change your world. Potato Salad fucked around with this message at 21:56 on Nov 15, 2017 |

Can the 900p run in DMI mode like NVRAM cards can? The x8 ones running in that mode can get something like 10million IOPS, it’s crazy. They have a supercap though for data backup to flash and the cards top out at like 16GB usually.

My son has an MSI Z270 motherboard (apologies in advance for red-on-black website). Am I right in thinking I can just get a Samsung 850 EVO and slap it in? I'm not interested in paying the price premium for NVMe. He's a gamer, and I'll be checking capacity with him. E: And I'm planning on checking for Black Friday sales just in case.

I mean, my hpc is pretty special snowflake rdma and IB poo poo, and I can test just about any kind of workload scientifically imaginable on there I'm sure cloudflare might have use for optane over just more ram, I guess? Maybe very specific cdn service? I would have told you a week ago that optane has very niche but strong use cases, but since testing it against second gen intel nvme or just looking at what more ram for slightly more cost can do over optane, I'm not seeing it.

If you have no physical space for a SATA drive. There's almost no reason to get a non NVME drive in M2 form because they're still more expensive than normal SATA ones.

The difference in price is oft times negligible, and even in cases where you *do* have enough space for a SATA drive, it eliminates two extra leads in your case.

But if you do snag one, be sure to research which slot on your son's motherboard is the twinned slot (SATA/NVMe-linked) and which SATA port plugging that drive in will disable.

The bottom 16x slot is usually DMI connected.

m.2 sata may seem like a weird thing for a person building a computer: "Why pay more for the same thing, just saving a cable?" Shift perspective to laptop manufacturers. The driver behind m.2 SATA has been space savings in the ultralight laptops that have been going up in power but coming down in price steadily this decade. M.2 SATA is a cheaper alternative to space savings without paying the premium of 2016 (and to an extent 2017) nvme pricing.

I posted in the laptop thread but I figured I'd post this SSD related question in this thread too. I want to install a second SSD into my laptop (ThinkPad W541). This laptop didn't ship with a CD/DVD drive, so the space where that would be is just empty, and I know lots of people buy optical bay caddies to do this but I was wondering if I could just skip that altogether and just use some cables and Velcro to secure the SSD in place. This is what the back end of a caddy that is advertised to fit my laptop looks like:  It looks like the left bit has 6 pins and the right bit has 7 pins. On my SSD (EVO 850) I count 7 + 15 pins. Looking at Wikipedia the 7 pin bits should be the data connector and the 6/15 bit part is for power. Would one of these Slimline 22 pin female to 13 pin male cables work then? I just don't see a point in buying a caddy if it's only function is to hold the SSD in place. Boris Galerkin fucked around with this message at 22:45 on Nov 16, 2017 |

You could velcro it in there, but those caddies are like $5 I'd just buy one. Buy why not just buy an M.2 SSD in the 2242 (42mm) size? Bob Morales fucked around with this message at 22:51 on Nov 16, 2017 |

Boris Galerkin posted:This laptop has one M.2 slot but it's used by the wifi card. Have you given any thought at all to how much it is going to suck to try to plug one of those cables into the connector all the way at the back of an ODD bay that you cannot conceivably get your fingers inside or see very well into? Or what happens if the cable is then too short to stick out the bay, so now you have to get the SSD onto the other end somehow? And then once everything's connected you have to pack the cable into the bay and shove the SSD in while hoping that you don't manage to lever the bay connector out of its socket. And then you have to worry about it working itself out over time, because the bay connectors are designed to rely on a mechanical latch or screw on the laptop to hold a ODD/caddy in, so they probably don't have detents to really hold the cable in. It may seem like a proper caddy does very little extra over a cable, but actually it does a whole lot and you will thank yourself for doing this job the right way.

Here's what I got in an email from Micro Center.. The original ad said the prices were only good to 11/19, but the ad on the website says the prices are now good until 11/23. The parts in the ad that are on sale say on the website that you have to check at the store for the price, but I'm reasonably sure they're what's in the ad out of the email. The 960 500 GB and the 850 EVO 500 GB are definitely on sale.

I'm thinking of re-purposing a M.2 SSD into a desktop without an M.2 slot. I see adapters to turn M.2 into both SATA and PCIE. Any advantages to one or the other. I'm assuming this is an active piece, rather than a passive metal passthrough. Should I be concerned about performance?

M.2 isn't magic, it basically either connects to a SATA bus or a PCI-E bus, often both, but the drive is going to be built to only talk to one. Find that out and then get that adapter.

Usually they are fully passive adapters going from m.2 to pcie aic (add in card) or m.2 to sata/minisas hd connectors. If you specify the drive and what you want to plug it into that’d help people give you a shopping list!
