I bought a Corsair Force MP510 960GB to put in the rest of the parts I also bought today. What's this that I'm reading about NVMe drives needing you to turn off write cache flushing to get to full speed? Is it a return of the old really bad advice from when SATA SSDs were just starting to become usable or is there actually any merit to it?

The only thing that's potentially advisable is installing the NVMe driver, but Corsair simply uses the generic one that comes with Windows. So no need to do anything.

Is it a return of the old really bad advice from when SATA SSDs were just starting to become usable or is there actually any merit to it? This is bad advice by the crowd who care about higher numbers on benchmarks. It does improve performance, but it can also corrupt your drive. Write caching is good (it's why drives with no dram are worse). Cache flushing is a command that the OS sends to make sure a write happens ASAP; not every write operation gets an immediate cache flush*. Turning off cache flushing is dangerous on most devices, but some server grade SSDs have enough capacitors to finish writing their whole buffer in the event of power loss. On those drives turning off flushing is a safe way to boost speed. *This is why in the past when people have pointed at some piece of software and said "look at the continuous writes it's doing, that will wear out SSDs" it's generally been a bunch of hooey. Most of those writes are not even leaving the OS buffers in main memory.

Folks, did I gently caress up? I ordered two Silicon Power A58s, one 512gb and one 256gb. The 512gb might become my unraid cache (primarily used to hold downloads during their first day before being moved to the array of spinning disks, and my dockered app's data, also some VM vhd usage), the 256gb will be used to recondition a laptop into a CloudReady Chromebook. However, any and every drive has horror stories out there. Reading this thread though, I've seen they might contain generally disliked controllers? Let me know quick as I can cancel the orders and hunt more.

There is zero chance I would use either of those SSDs for a cache drive assuming that cache is important. I'd try and get a Samsung I think.

It's not outright vital stuff but I'd rather it didn't fail at a bad moment (convienence, not data loss reason). I've switched that for the AData SU800 512gb. EDIT: But could change back.

It would be okay, but it's QLC SATA which will be slower than the Intel QLC NVMe 660P (if you have an NVMe slot free) or a TLC SATA drive (MX500, WD Blue, etc.). Both those other options can be found around the same price pretty frequently, although I'm not seeing something at this exact moment.

The new Inland Premium drives have a new sticker/heat spreader, so again, I'm wondering if 22.x means it's a new-build drive and incompatible with 12.x drives.

For game installs an 860 QVO is fine. Pretty much the only gaming situation where SATA vs NVMe makes a significant difference is when a game unpacks a huge file during initial loading, which is pretty much just Doom 2016, and only for that initial load. The biggest disadvantage of QLC is it's reduced write endurance, but Samsung seems to have decently overprovisioned because they warrant it for a decent load (360 TBW / 3-years) and running games isn't a very write-heavy application. An extra $10 for an Adata su800 would get you an extra 2 years of warranty, but the QVO should be just fine for what you want to use it for.

Ugh, not enough time in the evening yo look into which nvme my motherboard can use. Oh well, I can always pick up a 2tb samsung 860 evo. It's on sale a decent amount over at Amazon anyway. And if I'm screwing myself by not getting an nvme, I can always return it before opening it up. I'm legit that tired right now. Not enough time before I pass out. Best case I got a new 2tb ssd, worst case I send it back. Granted my current 2tb hdd is failing, so sending it back seems like a bad decision.

Unless you have professional applications that work with very large files, the real-world difference between NVMe and a SATA drive is pretty tiny. And if you decide to upgrade to an NVMe later SATA M.2 -> 2.5" enclosures are cheap, as are SATA M.2 -> USB 3.0 enclosures!

There are other equally good drives that are sometimes cheaper than the rocket but I can never remember which ones they are. Look at Stickman's posts in the part picking thread since he's the one who stays on top of all that. Wouldn't expect a hugely notable price difference though.

Oh. my. god. Adata's new SU750 (and amazon-exclusive 760) are powered by a Realtek controller chip. Realtek  The SU800 and Adata's various NVMe drives have a general thumbs-up from this thread, but a realtek-powered SSD is something I would rate as the strongest possible stay away. Like it's got really bad performance anyways, but even as a cheap media-storage HD replacement drive I don't trust realtek not to gently caress things up. Especially on their first try.

OK, so I can definitely notice the shortcomings with the new Samsung 860 QVO drives. No benchmark app or stress test required. I've been setting up a 1TB QVO for someone, and when copying data I'm seeing speeds drop to as low as 40 MB/sec when reading & writing for sustained periods. This is less than half the speed I'd usually get when copying from magnetic hard drives. Going by AnandTech's site (which noticed that "performance drops significantly"), apparently the 1TB QVO drive is rated at just 80 MB/sec when its cache is full (the 2TB/4TB QVO drives are rated at 160MB/sec, the old 250/500GB EVO drives were rated at 300 MB/sec, and the 1/2/4TB EVO drives were rated at 500MB/sec.) With regular Desktop usage, I guess the drive seems fine, as IOPS / small file performance is great (when everything fits in cache). It's just after using SSDs all these years, I didn't expect to see such a speed regression like this.

QLC NAND is extremely slow, which you'll definitely notice whenever the cache is full. It's why really cheap 2 TB drives like the Intel 660p (70 GB cache) are only recommended as secondary game drives, not primary drives. QLC also has pretty bad endurance compared to TLC drives.

This is true for all QLC drives - once the dynamic SLC cache is saturated they slow to hdd write speeds. The SLC cache is generally large enough that most people won't notice it outside of very large copy jobs, though - for the 860 QVO it starts at 42GB and bottoms out at 6GB (probably when the drive is >75% full, but I haven't found confirmation). Nearly every other usage scenario should be up with normal SATA speeds (or SATA+ in the case of the NVMe QLC drives). Stickman fucked around with this message at 23:35 on Dec 6, 2019 |

Nearly every other usage scenario should be up with normal SATA speeds (or SATA+ in the case of the NVMe QLC drives). Sustained writes to fill up most of a drive with an image clone or something like that during system setup is probably the worst case for a home desktop user with a QLC drive. Like, I'd guess when it drops to 40mb/s it's not only filled the SLC cache but also written enough data that the drive needs to downsize the SLC zone, so it has to evict bits from SLC to QLC. Or maybe just had a moment when the drive thought it had time to start re-writing cached data. So it's splitting that 80mb/s QLC write speed between your new copy and the drive's own internal copies. But yeah most any other time you'd stay inside the cache, or be downloading a game where the internet is the bottleneck. Anyways, Xenomorph posted:It's just after using SSDs all these years, I didn't expect to see such a speed regression like this.

Klyith posted:yup there's a reason the QVO never gets any recommendations around here. The 660p 2TB does, but that's because a) at 2TB the SLC cache is pretty huge and b) they actually discount it somewhat proportional to the QLC:TLC ratio. QVOs are stupidly overpriced and never worth it. Between a 2TB sabrent and a 2TB 660p I am happy to report that all SATA cables have been permanently evicted from my case. It is a strange sight seeing no hard drive cages and nothing in the 2.5'' caddies. TBF the SATA cables themselves weren't so bad - it was the drat power power connectors and trying to angle them into place.
