PCIe 5.0 M.2 SSDs

[mesaprotector]

Q1T1 randoms are improved for PCIe 5.0 too - just... not by much.

The problem is that sequentials at high queue depth are used as the main number for marketing, when in reality they're more of a nice bonus. Even an average user will appreciate that it doesn't take 20 minutes to copy all their photos to a new folder, or 15 seconds to get back from hibernation. They do matter, just not as much as randoms.

Man even a maxed gen 3 drive is plenty fast enough for me. These new drives with fans and heatsinks and transfer rates of 12,000MBps+... are just crazy to me. I would much more prefer consistent speed as opposed to racing to highest burst speed. w/e though. Technology marches on. I do kind of miss sata in the way that it didn't eat up all your pcie lanes though.

Yeah I'm happy with 500MB/s sustained. We are a long ways away for any consumer to benefit from these Gen5 speeds. Prosumer or Enterprise, sure I can see it being used now for big data sets.

Sorry don't mean to hijack the thread but do you have any recommendations for affordable and consistent well preforming sata drives? I was going to use my last 2 sata ports for another raid 0 config with 2 more mx500s, but their prices have rly gone up where I live ( like nearly doubled in price). Do you know of any alternatives I might be able to source from Canada? Also what do you think about sata in raid 0 in the first place? Its not for highly critical data so a failure is... not that big a deal.

I noticed the raid 0 drives do not trim. I'm not really sure what that means long term... just... the drive gets filled up with crap faster.... essentially? Maybe I don't need raid 0.... idk. Its just that it does improve those transfer speeds so much.

The benefits of sequential read / write speed increases for games drops off a cliff after PCIe 3.0. Even the difference between PCIe 3.0 and SATA is minimal. Suffice to say for the average user PCIe 5.0 is not worth it right now.

I saw some 2tb 970 EVO Plus gen3 nvme's last year for $78. Still kicking myself for not buying one or two of them, but most of my life I have been a fool, so its nothing new.

I like those older mx500s myself. The bx was TLC I believe and basically all the drives are now. You can get some good used enterprise ones on eBay for cheap these days. I snagged a Micron 9000 (something) 480GB that is rated for 1500 TBs write. $30 was the cost. Intel DC 3.8TB are cheap too .

No idea about Canadian websites

Not the best idea.

If your drive or configuration doesn't support Trim, it basically will have poor performance once filled up (the first time) and get uneven cell wear.

Yeah, no. The 990 pro is still the fastest nand ssd at Q1T1 and its gen 4. We're at drives already that are pretty much at get 5 sequential limits with overhead accounted for (14-15GB/s) if there was any improvement by now, we'd see it. Instead they double down on sequentials and this is why they've regressed despite pcie gen 5 itself also helping with slightly lower slot latency

Sorry read SSD reviews and see where the MP700 lands. Funny thing even though it is a 5.0 drive it is still cheaper than the 990.

Low cost SATA now reach 4TB at a given price per GB metric. M.2 NVMe now also are offered up to 4TB at PCIe 4.0 speed. My WD Green SN350 is 2TB which was the largest available of the line. Now cheap M.2 are bumping capacity as well as speed. My SN350 is installed in my Lenovo T14.

232-layer etc NAND chips are mass produced by several foundries which can handle demand efficiently. Taiwan, China, USA and Japan all have major NAND foundries.

Corporate servers want more M.2 logic for boot and for SAN servers. So new model NAND with more layers seems to be inevitable.

Ok

I bought a 1tb 990 pro without heatsink for 129. Then I bought a second 990 pro 2tb with heatsink for 169.

4 months ago I bought a 4tb 990 pro without heatsink for 249$ at microcenter here in Cambridge MA.
