every drive will reach it eventually, at least until you do a secure erase, then afterwards it can haphazardly place blocks again. this is the state most people will care about day to day and it used to be an issue when SSDs were in the teething phase, but the difference between "steady state" and "fresh out of the box" performance these days is within margin of error

Speaking of which, benchmarks only go really fast on sequential reading and writing. They're basically theoretical values that'll go to poo poo once the drive gets sufficiently fragmented, no?

if by "going to poo poo" you mean losing 12% sequential write speed if the lookup tables are less than optimal, sure

Internal block size on the e.g. Samsung EVOs is 2MB, NTFS cluster size is 4KB. There's a potential for a lot of mismatch. Write speed isn't so much an issue, I'm more interested in read speed.

lordfrikk posted:Is steady-state something that every drive will reach eventually (I guess like some kind of burn in) or does it require long enough uninterrupted usage after which it will return to "normal" (non-steady-state?)? I'm trying to understand if tests using speeds reached in steady-state are of any consequence for regular consumer workload. Steady state occurs when a drive has burned through its buffers and has to directly write and read to the NAND. Consumer models can sustain high levels for shorter amounts of time and are tuned for bursts of i/o whereas enterprise drives are tuned to provide better performance while in steady-state. Benchmarks tend to hit worst-case scenereos so this means more i/o than the buffers can take and then you get to see steady-state performance. On a consumer machine you will probably never reach a steady-state.

Tell that to my 256 GB Samsung 830 back when I was installing GTAV and had just cleared out 35 GB of stuff to make room for it. Turns out Steam's way of reserving the space is the old-fashioned write-a-giant-empty-file method.

I have an Adata SU800 (which is a cheap crummy drive) in my work desktop and an 850 Evo in my laptop and I definitely see a difference copying large files over. Samsung  Adata  The Evo can easily saturate gigabit ethernet on a large file, the SU800 does only for a short time before it runs out of cache. E. Both 250GB drives with a similar amount of usage.

100MB/s shouldn't be an issue for any SSD in the last 3 year should it? I mean my old Intel X-25 could do that.

If you have let an SSD get too full, will trim bring it back to normal performance when you remove some data? Do you need to secure erase the drive?

Building a rig, want an M.2 for OS and some programs/games. I am looking at those three. 960 EVO 960 PRO MP500 Which one should I choose? I don't know much about them. Any other models to consider?

Dante80 posted:Building a rig, want an M.2 for OS and some programs/games. Clarify first - do you want a NVMe drive or just a drive in the M.2 form factor? The former are significantly faster, but this isn't super apparent in daily use and they are significantly more expensive. If you just care about the form factor, I'd recommend the Sandisk x400 or the Samsung 850 EVO. Do note however, that you'll need to check with your motherboard manufacturer to make sure that it supports SATA M.2 drives, as not all do. Similarly, if you want a NVMe drive, make sure that it supports NVMe M.2 drives, as again, not all motherboards do. Other than that, go for the 960 EVO. There're very few reasons for a consumer to get a PRO drive.

Some drives can take up to 24 powered on hours before they do their internal cleanup and actually prepare those blocks for future data, so just deleting a whole bunch won't make the drive instantly faster.

If you can afford the price premium and if the things that PRO does better than EVO are important to you, then go PRO. However for normal consumers EVO is enough, the price hike for PRO is not worth it. A comparison chart seems to not be easy to find with google, but i found this (no idea how accurate it is): http://ssd.userbenchmark.com/Compare/Samsung-960-Pro-NVMe-PCIe-M2-512GB-vs-Samsung-960-Evo-NVMe-PCIe-M2-500GB/m182182vsm204072

Trying to order a few (~20) enterprise nvme drives (p3700 in this case) and not having much luck. The suppliers are all blaming nand shortage. This suuuuucks because we have to get them this quarter for budget reasons. Anyone know of comparables that might be available or are we just hosed?

However for normal consumers EVO is enough, the price hike for PRO is not worth it. Better is an odd thing to say when the provided use case is gaming + os drive. Going dramatically overboard with the enterprise drive's endurance and price with marginal gains in performance for home and games users can, in fact, not be "better." If the goal is to find a butter zone of performance, capacity, price and endurance, mind that the EVO is already a premium drive. Great value, but still premium. The nvme market has exploded with good poo poo in the middle and low ends and has had high-end consumer options for months. There's no need to go full Best Drive in the West out of fear for getting screwed on anything less on a new tech. The 860 PRO as an item marketed to anyone outside 4K video editing or hardcore knowledge workers is a "We're Samsung and we're the best" gimmick. The PRO may be m.2 god, but EVO is King.

Lol I just got an SSD off a friend who's more or less new to computers. He told me it was a "1.7 tb ssd hard drive drive ?? I got 2 of them from a coworker i only need one". I thought he just misspoke. I have it in hand now and it is indeed an unopened Sandisk Cloudspeed 1.7 TB Gen II manufactured a month ago. I couldn't even find it for sale online outside of ebay. My price: $80

I'm not one to feel queasy about "this was probably stolen down the line somewhere" for poo poo but this is kind of pushing it lol. I even told him look this is worth so much more but thats what he got it for. This is now the second "i dunno about this man" SSD adventure ive had in like 2 weeks. edit: I actually cannot find this model practically at all online. Sandisk doesnt appear to list it, though I dig too deep yet. There are like 2 other pictures of the thing on the entire internet one being sold on some out-of-US ebay website (despite the item being located in Salt Lake City) and some other website ive never heard of. The ebay listing was for $1100 too. The date of manufacture is 1/18/2017 and the PN is SDLF1CRM-017T-1HST and model is SXPLFA I'm wondering if this is some fake thing but I dont really want to open it either if its not. 1gnoirents fucked around with this message at 08:16 on Feb 26, 2017 |

If his friend works in a data center, you might be able to justify it as being a pulled drive, but being THAT new...I can understand your skepticism.

Got an 850 Evo in hk for better than even the newegg price and 1/3 less than New Zealand. Got other bunch of things that are a steal compared to nz. Should be even snappier than the 840evo which is going into the Windows part of the machine and that old ssd into the MacBook Pro. Then I will have a spare one I can flog off for some change.

You should be able to just copy the contents over, unplug the old drive, and use drive manager to reassign the letters.
