A fifth gen interface for a fifth gen network - Samsung announces PCIe 5 enterprise SSD

[williamcll]

Following 5th gen mobile networking and RAM, more hardware manufacturers are releasing 5th gen PCIe based solid state drives, Samsung has announced their model of ssd, which is going to compete with kioxia.

"Intel has been working with Samsung to test Samsung's newest PCIe NVMe SSD, the PM1743. Together, we have jointly resolved complicated technical issues encountered with PCIe 5.0 during this initial evaluation period. The performance potential of Gen5 is truly impressive. In the near future, we strongly believe that PCIe Gen5 systems with high-speed NVMe SSDs will have the ability to transform applications such as AI/ML and high-performance databases," said Jim Pappas, Director, Technology Initiatives, Intel Corporation. "Looking ahead, we are confident that Intel and Samsung's continued commitment in industry leadership will provide these and other benefits to our mutual customers."

 

Samsung’s PM1743 will feature a sequential read speed of up to 13,000 megabytes per second (MB/s) and a random read speed of 2,500K input/output operations per second (IOPS), offering 1.9x and 1.7x faster speeds over the previous PCIe 4.0-based products. Moreover, write speeds have been elevated significantly, with a sequential write speed of 6,600 MB/s and a random write speed of 250K IOPS, also delivering 1.7x and 1.9x faster speeds, respectively. These remarkable data transfer rates will allow enterprise server manufacturers deploying the PM1743 to enjoy a much higher level of performance. In addition, the new SSD can provide improved power efficiency of up to 608 MB/s per watt, which represents about a 30% boost over the previous generation. This is expected to lower server and data center operating costs significantly, while also helping to reduce their carbon footprint.

 

My thoughts

Hopefully the prices for PCIe5 SSDs aren't as bad as RAM. Although at the current situation the Kioxia PCIe5 SSD seems like a faster choice but I'll have to wait for the reviews to get a confirmation.

Prices of DDR5 are high because most of the supply is going to OEM's. There's plenty of NAND to go around. These won't be inflated price wise. 

 

Can't wait for the day these speeds actually mean something to most users.

it does now? Media files are constantly going up in filesize. Why do you think people need RAMDisks?

That day will be a long, long time away. There's barely a need for Gen4 speeds. The primary benefit to PCIe 5.0 and even 4.0 before it is increased I/O, not necessarily the speed thereof. For example, you could run 4 Gen3 drives at full speed on PCIe 5.0x4. Its going to be very important for USB4, as well, once they arrives.

In before some clueless person goes "but who is this product for", or "nobody needs something this fast"

 

For all practical reasons we've had PCIe SSD's of this bandwidth before, but they had to be PCIe x8 (4.0) or x16 (3.0)  add-in cards. The existing m2 designs were not designed for enterprise use. Never were.

Available in a wide variety of capacities from 1.92 terabytes (TB) to 15.36TB, the PM1743 will be offered in the conventional 2.5-inch form factor, as well as in a 3-inch EDSFF (E3.S) — an increasingly popular SSD form factor designed specifically for next-generation enterprise servers and data centers.

Looks like Samsung is abandoning their alternative to EDSFF which was NF1, as I don't see it mentioned in the article.

I expect 990 Pro sometimes next year.

woah woah, did we skip a gen now?

Also, will there be similar issues that gen 4 had?

Samsung SM/PM series are OEM drives, kinda parallel to consumer Evo/Pro but you still need the numbers to know which one it is.

I tried it once to try to reduce game loading times. It did work, but hardly any difference to Optane and only slightly faster than upper-mid range flash NVMe of the time. As so often the case, it is a software limitation.

buuut I need 256gb ram disc for my floppy drive!

256GB, that is both a lot of ram and a hell of a lot of floppy disks lol

Then get this new SSD, it can 

 

Also I hope you are running active-active multiple paths

Well of course, if you're not running at least dual path you're doing it wrong

The enterprise/datacenter products also use this naming, which this one is. SM/PM SSDs are more commonly those, but you are right OEM SSDs found in laptops also use that naming too. Samsung wouldn't use those OEM model names in a press release though.

 

This model of SSD will be rather $$, 5-7 years will make a nice second hand purchase

So what you are saying then is full mesh = best 

 

Wonder what the most ports you could even get in to a server? Hmm? 9 PCIe ports, quad port NIC, split port channels in to 4 (yea I know this isn't actually supported host side, just go with it).

 

9 * 4 * 4 = 144

 

How many hosts for 144 full mesh links.

Another lapse in my knowledge, due to lack of exposure to that market. I suppose I would have been more correct to say "not intended for direct sale to consumers by itself".

Back to similar discussion in another thread, if only there was more used enterprise hardware entering the used markets where I am.

the software industry will find a way to make their code so much more inefficient so as to undo these gains. 

They always do lol

Not just full mesh but redundant full mesh!!

Probably not anytime soon as there's always a market for tiered storage integration and upgrades.

The thing people end-users don't realize is that you can not update the firmware on the PMxxx drives. I have never seen a firmware for one. Everything else, yes.

So I did the math: That would require 182,045 high capacity floppy disks (1.44MB) and it would only take a little over a month (31 days, 1 hour, and 41 minutes) at a typical 100 KB/s read speed, not accounting for the time to switch out the disks.
