"incredible speeds up to 1000mb/s"

The p3 drive that's on sale now is 3500 mb/s unless the cache is full.
The theoretical maximum of USB3 10G is 1250 mb/s, so it's likely not far from 1050 mb/s with overhead. This is as fast as you're gonna get with a normal USB port.

You can go over the usb3 maximum speed if you have a thunderbolt enclosure, can't you? there's also usb4.

But let's say that you don't use thunderbolt and just want regular USB3, with the P3 you can choose to install it on a nvme and get the full speed or keep it in an enclosure.

Why would you intentionally limit your options?
Thunderbolt and USB4 aren't on normal USB ports. I'm talking about the rectangle one. The rectangle USB port tops out at 10 gigabits per second, no matter what device you use. Most devices don't have many, if any ports faster than this.

You might be able to sustain the maximum data rate for longer with a beefier M.2 SSD and enclosure, and you may also get faster random speeds. But 1250 mb/s is 10 gigabits. That's all the good ol' rectangle can do.

This is likely more compact than an enclosure would be, since it's not designed to be opened. It also might be water resistant and more durable.

I don't know why you mention the "rectangle" USB as is that's relevant.

MacBooks don't have any "rectangle" usbs anymore, Samsung laptops don't have rectangle usbs anymore since the Galaxy book version 1 and that's a 2019 laptop. Devices have had thunderbolt ports for years.

"Rectangle" USBs are on the way out, and usb4 is what we're moving towards.

Arguing for "rectangle" USBs now is like arguing for micro USB few years ago instead of usb-c because that's what was more popular at the time.

With the P3, you can use it in an enclosure and use legacy "rectangle" cables for speeds up to 1050mb/s (that match this drive), you can use usb-c cables in a thunderbolt/usb4 port for 3500mb/s the speed or you could install it on your motherboard for 3500 mb/s the speed.

if you don't value faster speeds when using modern devices and the flexibility to go from internal to external storage and plan on only using it as external with legacy devices, that's fine.

I'm just letting others consider this point in case they do value them. that's the point of the discussion section.

I have the 1TB version of this drive. It's well built, small, and fast. I paid $90 for the 1TB last last year. Big price drop!

Thunderbolt enclosures cost $100+ as do usb4 enclosures. This drive is essentially a p3 with dram in an enclosure. It can be removed and put in a motherboard and achieve the same speeds as the p3. The speeds listed here are specific to this enclosure's usb speed limitations but that would be the same specs as a usb3 enclosure. So this is a better deal as it has dram, the same storage media and a really nice enclosure.

Just remember the SSD inside is a QLC drive. I have a 2 TB version that I got on a recent sale for $90 and if I transfer large chunk of files (>250 GB), it slows down to ~50 MB/s. 2 TB version has roughly 250 GB SLC cache so at least this one should be larger. Cache takes some time (~30 min) to fully empty.

This or the internal 4tb mx500 performance wise? Which has a bigger SLC cache?

Don't believe this drive has DRAM

You guys are killing me, writing megabytes per second with a lowercase "b" (and "m").

Megabytes per second is MB/s or MBps
Megabits per second is Mb/s or Mbps

There's an 8x difference!

Same goes for GB/s and Gb/s (1250 MB/s is, indeed, 10 Gbps)

There, I've corrected some random people on the internet and my conscience is now clean :-)

For me, my 1TB 7,000 MB/s primary OS drive, and 2TB 5,000 MB/s secondary drive fill both slots my laptop has. Adding in a 1,050 MB/s storage/tertiary drive for lower demand tasks that can run on a USB A shaped port and keep my TB4 port open for other use, as well as use as a portable sharing drive with ANY older machines for support, this is a perfect fit.

I know and accept this is slower than an internal. But even in it's shucked form it's slower than either installed drive. But it beats the old 5400 RPM storage drives of the past and won't take up any of my more valuable ports.

I also do a metric ton of support work on computers of all ages. The USB A functionality is so absolutely universal, this would be perfect for so many uses. But it's flexible enough that I can use it as a 3rd dive still for myself. A pretty optimal balance for many users/tech people like myself.

That said, I won't get this for myself, as I've got my eye on the Sabrent dual NVME dock that can also clone. When I have a need, I'll be getting that with a drive. For now, 3TB is still holding me over comfortably.

The Crucial X8 4TB drive includes a USB-C to USB-A adapter, so you're free to use this with a USB-A (rectangular) port. One of the pictures on the Best Buy item page shows the dongle.

I've found that the dongle attaches fairly firmly to the USB cable, and I can't recall it coming off in my bag, so I'm not overly worried about losing it. YMMV.

This for bursts of writing that aren't over 200GB. The MX500 for slower but continuous speed at all data sizes.
