I am looking at 3 brands for about the same price range for a 512 GB unit as follows. HP EX 950 SRG SX8200 WD black SN750 Now I have to admit I have never looked at NVME drives much before so I am kinda behind the curve on this, I have looked at piles of reviews and these 3 all get excellent marks, so now I am torn between them and can't decide which one to buy. So if anyone out there has any preferences or warnings I would appreciate their input, Thanks in advance. I'm no help on the choices above because each of my m.2 drives is Samsung. (I've had zero issues and personally won't be looking at other brands.) You're starting out well, though, because you're specifying m.2 NVMe and not m.2 SATA. m.2 is only the form factor, where the numbers that immediately follow refer to the drive's size in mm. I.e., m.2 2280 is 22mm wide and 80mm long. Whatever you decide, be sure your mobo physically supports it. You'll need the standard m.2 socket, plus a hold down screw at the desired distance from the socket. Also take a look at the mobo manual because, typically, adding an m.2 drive will take away some other capability, such as disabling one or two SATA ports or stealing a couple of PCIe lanes from one of your PCIe slots. Make an informed decision and you'll be fine. One final note: the boot drive in my latest build is an m.2 NVMe, which specs out at some crazy data transfer speed, but other than super fast boot times you'll very quickly become accustomed to it such that it no longer seems 'fast'. It just seems normal, as if things have always been that way. Even so, I wouldn't go back to vanilla SATA. Yes the Mobo supports X4 and will come with 2 M.2 slots for all lengths 40, 60, 80 and 110 mm and 2 mounting standoffs and screws, Sata 1 will be disabled when adding the NVMe drive. Yes Samsung is pretty well tops but for my casual use the lower price ones should be OK.

Â*Â*Â* The Sequential Performance page shows 2300MB/sec read at 1TB capacity. Â*Â*Â* (As usual, "no, it doesn't read at 3500MB/sec".) You would compare the HP EX950 to the Samsung 970 EVO PLus and see if the price of the Samsung is work an extra 200MB/sec write. Since the HP performance is size-dependent, you have to compare "like to like". Then see what price the name brings. You consider the power rating, if there is any danger of the product "throttling" due to overheat. This has been a bit of a problem in the past with NVMe. Maybe the bottom gets a bit warm on them. You can't expect to be pushing 2GB/sec toggle rate on logic gates, doing ECC at speed, without something getting warm :-) The record for warmth goes to some of the PCIe card form factor products, like an Optane card. Which is probably over 15W or so. Whereas a tiddly SATA SSD can be 5V @ 300mA when writing. Â*Â*Â* Paul The new SRG SX8200 PRO is 512 instead of 480 and sports the new SM2262en controller, Yes both that one and the HP are very nearly identical.

Â*I choseÂ* Door 2, The Adata SRG SX8200 512 GB unit and ordered it from Amazon at a price of $129 cdn. free shipping 2 day delivery. When I get all this stuff bolted together I will certainly do a lot of bench-marking and post results and then the truth will shine forth. Â*I am really looking forward to this as I haven't done a new build in 9 years Â*Thanks for your help and research Rene Well I put it all together today as the last part came in yesterday afternoon. Two problems slowed me down. 1: the IO shield would not install, I have to work it over carefully with pliers before it would snap in. On 1rst boot it brought up the bios and would go no further, Had to do a lot of manual perusal before I figured what to do, which was Enable CSM whatever that does. After that it booted right into my old Windows without any problems. I then loaded the driver disk and everything works A1. Tomorrow I will have to reactivate it with Microsoft, And clone Windows onto the new NVMe I did two quick benchmarks as follows CrystalMark. Read 3,470 Write 2,386 ATTO Read 3,281 Write 2,399 So this pleases me beyond my expectations, Hadn't hoped for that much improvement. Rene |

CSM is Compatibility Support Module. It's for newer motherboards that boot using UEFI to provide a BIOS style boot environment for older operating systems like Windows 7 or older. -- Roy Smith Windows 10 Forté Agent 8.0 |

Major upgrade
Wow, almost like mine but I'm not planning to upgrade yet unless
something break. I used to upgrade like crazy because I was computer gaming. :P Rene Lamontagne wrote: I am contemplating upgrading my I7 950 system due to age, which I built in 2010.

So Look at the component choices I have made and let me know if there are better choices without going to extreme high end kit which I really don't need. This is not set in stone as I need to have a serious discussion with my Financial advisor (myself). :-) Thanks to all Rene -- Quote of the Week: "Lay a stick of bubble gum on an anthill for instant Siamese Ant Twins." --unknown Note: A fixed width font (Courier, Monospace, etc.) is required to see this signature correctly. /\___/\ Ant(Dude) @ http://aqfl.net & http://antfarm.home.dhs.org / / /\ /\ \ http://antfarm.ma.cx.
