Specification of new NVMe SSD to be purchased.

**satimis** · November 21st, 2021

PC HDDs config:
==========
1TB NVMe SSD for running OS
4TB WD HDD for data storage

Now NVMe SSD is having insufficient space and I'm prepared to buy a new 2TB NVMe SSD.

Running following commands I found;

1)
$ sudo lsblk -e7

Code:

2c)

Your current drive model is a QLC drive. These are the least expensive X4 drives for given capacity. But, they are slower and less durable than TLC drives, especially when writing to the disk. I would opt for a TLC drive myself. There are pros and cons. Read:
Article on pros and cons of QLC flash
Other than that, be sure it has 4 channels (X 4) and not 2 (X 2) which would slow it down by 1/2. Most sold are (X 4).
Much depends on your use case.

**oldfred** · November 21st, 2021

What does this show?
udisksctl status
and/or nvme, you may need to install
sudo apt install nvme-cli
nvme - the NVMe storage command line interface utility (nvme-cli)
nvme --help
sudo nvme list

Have you updated firmware on SSD & motherboard?
What does motherboard manual say about NVMe drives.
Some new ones now support more than one, but may prevent a SATA port from working or not have full speed on second one.

Do not know LVM, but those that do always want the LVM commands to see details.
sudo pvs
sudo vgs
sudo lvs

I upgraded my M.2 SATA SSD to larger NVMe SSD and put M.2 SATA drive in an external enclosure. Now sold on external SSD (really fast) over flash drives (really slow). Not sure that you get any extra speed thru USB3 adapter fro NVMe, perhaps with USB-C to take more advantage of NVMe's faster speeds.

Hi oldfred,

Thanks for your advice.

This AMD Ryzen 5 PC was built about 3~4 years ago. I have been planning to build a new AMD Ryzen 7/9 PC sometimes but unable to find spare time.

Hi Dennis,

Thanks for your advice.

How can I check the spec of the running NVME SSD, pcie 3.0 or 4.0 ?

Edit
===
This PC is running Oracle VirtualBox with Ubuntu20.04 as host.

After adding a new 2TB NVME pcie SSD I'll use the old one to running KVM/QEMU. I need speed.

Do not know Intel, but quick Google search said this site had firmware.
https://www.intel.com/content/www/us...d-storage.html

https://www.intel.com/content/www/us...date-tool.html

You compare the FW rev (firmware revision) number shown in nvme or udisksctl output. And then see if they have a newer one and how to install it.
With my Samsung it was a bootable ISO that was old school. Looked like an old DOS screen with just one update for my model NVMe drive.

To convert SATA SSD to external I had to buy a external enclosesure/adapter. Was inexpensive, but I noted the NVMe cases were more expensive. I do not think I would buy a NVMe drive to use as an external as extra speed would not be available. But since you will have one, then worthwhile?

PCIe 3.0 x4, NVMe

**Dennis N** · November 22nd, 2021

To get the information on your Intel drive, I googled the model number you showed in your output. It's PCIe 3.0 x4, NVMe QLC but the indicated read and write speeds are just 1800 MB/sec. A PCIe 3.0 x4 TLC drive would be rated nearly twice as fast.

The specs say the Intel 660p is a PCIe 3.0 x4, NVMe device. You can use PCIe 3.0 devices in a PCIe 4.0 slot, but it will work at PCIe 3.0 speed.

The 4.0 x 4 drives are going to be a lot more expensive for a given capacity.

If you are using a SATA drive as well, copying stuff from the NVMe drive to the SATA would be limited to the SATA drive speed. A SATA SSD max speed is around 500-600 MB/sec.

According to my recollection my NVME pcie SSD is pcie 3.0 ? How can I check it on Terminal? Thanks

The 4.0 x 4 drives are going to be a lot more expensive for a given capacity.

Apart from cost is there pcie 4.0 x 4 slot on my motherboard?

Storage

Code:

AMD Ryzen™ 5000 Series/ 3000 Series Desktop Processors :

Support Raid 0, 1, 10

I'm running Oracle VirtualBox here and I need speed. Is there any advantage on running pcie 4.0 x 4 SSD ?

If you are using a SATA drive as well, copying stuff from the NVMe drive to the SATA would be limited to the SATA drive speed. A SATA SSD max speed is around 500-600 MB/sec.

I only have one 4TB WD SATA HDD for data storage. There is no OS running on this HDD. Speed is not important

I suppose;
1) 002C is the firmware version of my NVMe pcie SSD
2) BTNH93310UXC1P0B is the serial number of my NVMe pcie SSD

But I couldn't re-confirm the firmware version according to following document;

running following commands on Terminal as advised on the said document;
1)
$ sudo fdisk -l | more

Code:

Nor I can compare 002C, the firmware version of my NVMe pcie SSD with following URL;

Because I couldn't find INTEL SSDPEKNW010T8 on that page, the disk model of my NVMe pcie SSD

I don't have NVMe external enclosesure. Nor I would consider converting my NVMe pcie SSD to external

Yes, that's going to be compatable. Probably the best you could get. Speed ratings from Samsung: Read/Write Speeds 7,000/5,100 MB/s (these are probably the maximums).

In fact, you have two m.2 slots on that motherboard from the illustration on the Asus product page. At least one should be PCIe 4.0.
