Reddit mentions of Samsung 970 PRO SSD 512GB - M.2 NVMe Interface Internal Solid State Drive with V-NAND Technology (MZ-V7P512BW), Black/Red

The best you can get right now hands down is the Thinkpad A no doubt. Configure it as a 2700U and multi-touch display and base memory. You can install better memory for yourself, and even an PCIe NVMe SSD for a nice boost. Or pay the 100-300USD to not do it. It can do light gaming and all. It's about ~950USD. This can sustain performance for days due to it's thermals.

Unless looks and flexibility is more important than performance, as if you don't game or do anything remotely intensive in a browser, in which case the Matebook D works since it's much cheaper at around 550USD.

But whatever you do, don't get the HPs. Bad screens (generally hit or miss depending which on you get and when) and they are thermally bad, limiting performance. Not to mention the half-decent Envys still cost more than the Matebook.

EDIT: Other dude is right, might want to look into the E485 or E585 if you want better thermals. Not to mention it'll cost about 600USD to 800USD USD. There are some stuff missing from it, but the performance should be similar for longer.

Awesome choice!

... but now you should resubmit your order. :) You mention that the cost was prohibitive, but you could save a lot of money by upgrading the RAM and SSD yourself.

When it comes to SSDs, you could get the (faster than whatever Lenovo's shipping) [Samsung 970 Pro] (https://www.amazon.com/Samsung-970-PRO-512GB-MZ-V7P512BW/dp/B07C8Y31G2) for way less than the $200+ US price increase for the 512GB SSD option on Lenovo's site. Or you could get the [970 Evo Plus] (https://www.amazon.com/Samsung-970-EVO-Plus-MZ-V7S1T0B/dp/B07M7Q21N7) for a lot less, the [WD Black SN750] (https://www.amazon.com/dp/B07MH2P5ZD) for even less, etc.

You could also get more for your money. For instance, for less than the price of upgrading from 8GB to 16GB of RAM on the Lenovo site, you could buy an extra 16GB, install it yourself and wind up with 24GB.

(Prices checked are in USD, but the same generally holds on other global sites.)

Why would you buy this over the 970 PRO that's cheaper?

In all our dreams my dude

$229 for 512gb

So, here's some thoughts in no particular order.

RAID(Z) IS NOT A BACKUP. There are only 2 reasons to use RAID, speed and availability. So if you don't want to lose the entire array (data is difficult to replace/there is no complete backup), maybe look at RZ3. If, on the other hand, the data is replaceable and backups are had then feel free to stick with RZ1 and assume that you will probably get a final, incremental backup if you are properly notified of a failure. (With 8TB disks almost down to $100 when they show up on sale, its not too bad to backup even relatively large arrays.)

There isn't any particular reason not to combine nfs2 and nfs3. It will boost your speed. I would look at striping some RZ2 or RZ3 arrays.

The only right way to expand your big nfs2,3 is to add the same number of disks again, or replace each disk.So pooling them and using smaller stripes makes it easier to expand. For example, with those 2 arrays, if you need to expand both that's 16 more disks. But if you, for example stripe them, than you can expand both 8 at a a time. Similarly, mirrors are great because you can expand 2 by 2. (I love mirrors, but the parity cost is pretty big.)

Similar to above, a larger number of smaller drives is cheaper to expand. Also quicker to resilver and less likely to fail during resilvering. So consider a 4u chassis with 48 drive bays and load her up with 2TB drives. Say, 6+2 x 5. This would be highly performant, cheaper to expand (8x 2TB as opposed to 8x 6TB), and less dangerous (quicker resilver hence less likelihood of a 3rd failure).

I would bet your SMB performance comes down to configuration. There are a lot of settings buried in ZFS--things like setting log_bias==throughput for dbs and for large, sequential writes are often overlooked. Not to mention the varied settings in SMB/CIFS itself.

I tend to eschew 3 and 6 TB drives but I'm probably just superstitious. (There had been some 3TB drive issues when that size first came out.)

NFS1: HDDs are really bad at the kind of random I/O load you get from hosting vm files--you'll often see speeds around 100Mbps for SATA. So, I wouldn't expect near even 1Gbps on 2+2RZ2. (For example, this SAS drive.) You want, instead, either SSDs or a bunch of HDDs. By a bunch I would say 10-20 to get mulitgigabit speeds. Look at that speed test again: expect 100-300Mbps/disk depending on your seq/rand mix. SSDs are awesome.

Also, with VM storage I much prefer a mirror to RaidZ. Don't ask, it's the impression I get. Also, this maybe less applicable for VMDK than my usual file-level VM storage. (There's a reason that small files in a RaidZ array are mirrored rather than parity'd.)

ZFS just started allowing you to designate drives for metadata and for small files, as well as the good ol' slog. Consider mirrored ssd/nvme drives for metadata for all of the pools, and probably small files as well. This can be done well for $130, and right for $350 (enterprise or samsung pros). If your board supports it, optane is a good choice for this. If you do stick with HDDs for you vms hosting, consider using these drives as a slog, too, for that pool.

Don't get SAS drives (maybe for the vmdk pool, maybe) There isn't a substantial reliability benefit and your large pool doesn't have much random I/O so won't benefit much at all performance-wise. And the cost difference is...not worth it. (WD red 6TB for $70, Seagate 6TB SAS $140...you'll save well over $1000 using sata.)

In fact, if you go with the 2TB drives, I wouldn't even worry about a separate drive pool for vmdk. Just get a good nvme slog/meta/small-file mirror (970 pros, or if you just want to spend money these would be awesome) and go to town. Even at the low end, 40 drives will still get something like 6-8Gbps for highly random i/o loads. Mixed with your sequential, you'll likely see closer to 20Gbps.

Do it. Samsung NVME is so worth. My suggestion would be a Pro ($$$) and 512gb but I'm a bit crazy in my performance demands. 500gb wouldn't hurt tho and the pro is like $25 more.

If its too expensive, scale down as needed. Preferred 970 pro due to write endurance vs evo and speed hike from 256gb variant.

Note: make sure you have High Sierra installation performed, even to external hdd ( need firmware update for nvme drive to be detected)

Do you mean a 970 PRO? I can't find an 870 only the 860.

This is the drive I bought

Cool. So the Samsung 970 is the MVMe tech you're talking about? That plugs directly into the motherboard, correct? I'll just have to make sure mine is compatible.

It is mostly for gaming but it'd be nice to get ahead of the curve in terms of speeds so I don't have to replace this for a while.

The one I got is this: Samsung 970 PRO 512GB
Cost me about 250 Euro, probably a bit cheaper now.

I got this one

I was reading the information off this article, are they misleading us in what they are saying, or are you underplaying the performance of the NVMe SSD drives, or is something else going on I am missing? From the article, it sounds and looks like they are talking about a single drive with 4x1GB channels connecting to it, and the claim on that specific product is 3,500MB/s. Wouldn't that be a 5-6x performance improvement?

The relevant part of that article is this:

>Revisiting Samsung's recently-released 970 PRO NVMe SSD, it sports an M.2 2280 (22mm by 80mm) form factor and uses four PCIe 3.0 channels (x4). It is capable of reaching read speeds of up to 3,500 MB/s and write speeds of up to 2,700 MB/s, give or take some MB in real-world use and under varying configurations and operating conditions.
>
>By comparison, the 860 EVO, also sporting a 2280 form factor but with a SATA interface, can hit read and write speeds of up to 550 MB/s and 520 MB/s, respectively, on par with the 2.5-inch SATA 3.0 version of the SSD that can slip into a system's drive bay.

​

> You literally just picked the most high end m.2

LOL? I didn't even pick the highest end Samsung drive, let alone the best SSD.

The Samsung 970 pro is better than the evo at $150

The Intel Optane 900p is even better than that at $500

So no, I didn't pick "the most high end" SSD, not even close.

There are plenty of reputable brands besides Samsung and Intel (Crucial and WD are good examples.), but Inland is not one of them.

All that and you got a sata drive?

Dude get an m.2 drive its the most noticable upgrade in daily use that has come out in a decade.

Can you explain the differences between the pro, evo plus, and pro evo? There's a bunch of different models and it's confusing. Just finished reading this article and I still don't understand the differences. The Pro version is somehow cheaper than the Evo Plus version.

Edit: Found the difference here

>The EVO is the 2018 version of their drive. Its 64 layer memory. On the 1 tb drive has an endurance of 600 TBW(Terrabytes Written)

>The PRO is the better version the 2018 EVO. Its also 64 layer memory, but faster than the 2019 EVO. It has an endurance of 1200 TBW on the 1 Tb drive.

>The 2019 EVO plus is a 96 layer memory. So its faster than the EVO and almost as fast as the PRO. Has an endurance of 600TBW on the 1 Tb drive.

>The performance advantage a plus has over a pro is that on big file writes, it can write for longer without throttling due to overheating.

>Price wise Plus is about the same as EVO but pro costs ablut 100 dollars more than the other options.

>Plus has better value for most people. Except for people who need high endurance, like video editors, motion graphics artists, etc.
