The cheaper WD My Passport SSD and SanDisk Extreme have WD's Blue SN550E inside them, too. This drive is powered by a WD SN730E, as mentioned in the review, so I already know the specs inside and out. It's hard to or impossible to open some of these without destroying them, which I try best to avoid. it will also help you to determine TBW/IOPS if the external drive does not say just by discovering which NVME SSD they are using inside.Yes, most are just M.2s in an enclosure. Īlso you need to tear down the External drives in each review to see which NVME SSD is in there.

I am 100% sure you will find the same Version of SANDISK Extreme Pro as a stand alone NVME.

TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops.Ĭan you please gather the best NVME external boxes in the market and test them with something like Samsung 970 Evo Plus or 970 pro ? make a round up ? and see if they reach 3000MB/s ?īecause all portable SSD are a box with internal off the shelves NVME SSD. I have tested the internal M.2 SSDs by themselves on an X570 platform, you can read my reviews on them if you are interested.Īlso, that enclosure is made with an older Alpine Ridge TB3 controller, not titan ridge or newer like on some of these portable SSDs. You can't compare the performance or thermal characteristics of these portable SSDs without using the default enclosures and bridge chips. Thus, comparing just the underlying storage alone. Seanwebster said:At that point you wouldn't be testing the actual portable SSDs as they are, you would just be testing the performance of the internal SSDs in that one enclosure. Maximum temperatures hit roughly 48 degrees Celsius on the surface (S.M.A.R.T. While the drive runs warm, it will deliver exceptional performance most of the time thanks to the chassis acting as a heatsink. The performance never slowed due to throttling, even after writing 600GB of data to the devices. data reports a device temperature of 44 degrees Celsius.) SanDisk’s Extreme Pro v2 idles a little warm, with the surface of the device measuring 40 degrees Celsius when simply connected to the system, or roughly 6-10 degrees Celsius hotter than most 10Gbps devices.

After 30 seconds of idle time, the SanDisk Extreme Pro reclaimed the full capacity of its static SLC write cache. The SSD wrote 32GB of data at a rate of roughly 2 GBps before degrading to a consistent direct-to-TLC performance of 1.6 GBps. Second only to the super-expensive 8TB Sabrent Rocket XTRM-Q, SanDisk’s new 2TB Extreme Pro v2 boasts impressive write performance. Bear in mind that results will vary based on the workload and ambient air temperature. data and an IR thermometer to see when (or if) thermal throttling kicks in and how it impacts performance. We also monitor the temperature of the drive via the S.M.A.R.T. We also monitor cache recovery via multiple idle rounds. We use iometer to hammer the SSD with sequential writes for 15 minutes to measure both the size of the write cache and performance after the cache is saturated. Sustained write speeds can suffer tremendously once the workload spills outside of the cache and into the "native" TLC or QLC flash. Most SSDs implement a write cache, which is a fast area of (usually) pseudo-SLC programmed flash that absorbs incoming data. Official write specifications are only part of the performance picture. Write speed and temperature are two important and inter-related metrics for external devices.
Sustained Write Performance, Cache Recovery, and Temperature The NVMe protocol aids the Thunderbolt 3 SSDs, so they tend to respond much faster across the board. SanDisk’s Extreme Pro v2 displays very strong sequential read and write performance with notable gains at smaller file sizes compared to the older WD Black SN750-powered WD Black P50.
