Samsung T1 Portable SSD Review (1TB) – Price, Speed, Capacity and Security


SSD Testing at TSSDR differs slightly, depending on whether we are looking at consumer or enterprise SSDs.  For consumer SSDs, our goal is to test in a system that has been optimized with our SSD Optimization Guide. To see the best performance possible the CPU C states have been disabled, C1E support has been disabled and Enhanced Intel SpeedStep Technology (EIST) has been disabled. Benchmarks for consumer testing are also benchmarks with a fresh drive so, not only can we verify that manufacturer specifications are in line but also, so the consumer can replicate our tests to confirm that they have an SSD that is top-notch.  We even provide links to most of the benchmarks used in the report.

ASRock Extreme11 X99 Test Bench 60

This is a brand new test bench and, as such, we would love to thank those who jumped in specifically to help the cause.  Key contributors to this build are our friends at ASRock, Corsair, Kingston with components from past contributors to include In-Win, EVGA, beQuiet, and QNIX.  We have detailed all components in the table below and they are all linked should you wish to make a duplicate our system as so many seem to do, or check out the price of any soul component.  As always, we appreciate your support in any purchase though our links!


This Test Bench build was the result of some great relationships and purchase; our appreciation goes to the below mentioned manufacturers for their support in our project.  Our choice of components is very narrow, in that, we choose only what we believe to be among the best available and links are provided to each that will assist in hardware pricing and availability, should the reader be interested in purchase.

The software we will be using for today’s analysis is typical of many of our reviews and consists of ATTO Disk Benchmark, Crystal Disk Info, Crystal Disk Mark, AS SSD, and Anvil’s Storage Utilities. We prefer to test with easily accessible software that the consumer can obtain, and in many cases, we even provide links. Our selection of software allows each to build on the last and to provide validation to results already obtained.


Crystal Disk Info is a great tool for displaying the characteristics and health of storage devices. It displays everything from temperatures, to the number of hours the device has been powered, and even to the extent of informing you of the firmware of the device.

Samsung Portable SSD T1 Crystal DiskInfoSamsung provides some key SMART attributes to monitor the Portable SSD T1 with and, as we can see, it is also TRIM compatible.


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.

Samsung T1 External SSD (1TB) ATTO
ATTO provided high read and write speeds of 445MB/s read and 427MB/s write, these being true USB 3.0 UASP performance and just below listed specs, possibly the result of our Windows 8 system, vice that of Windows 7 which typically brings slightly higher performance.  More importantly though, the speed progression as file size increases is solid and indicative of a strong SSD.  Interestingly enough, Samsung provided different benchmarks to display the difference between Win 7 and Win 8:

Windows Speeds Compared

    If only it was the new USB 3.1 🙂 Damn that would be awesome!

      David you are right. Time is over for the 3.0. Too late for these devices. 3.0 was announced in 2008 and they offered 10 MB write 40 MB read drives for years. Still more than half of the 3.0 drives are 10 – 15 MB write 70 – 80 MB read. 3.1 was announced in 2014 and when 3.0 died producers started to offer 400 MB drives. Patriot renewed Supersonic Magnum series with 300 MB write 400 MB read speed. Corsair renewed Voyager GS and GTX. Lexar renewed P10 to P20 with 270 MB write 400 MB read. I do not care any of them. Also I do not care Samsung T1. It is high time for 3.1. Remember CES 2015. ADATA SE700 portable SSD with USB 3.1 interface. The drive offers sequential transfer rates of up to 819 MB/s read, with up to 839 MB/s writes.

    It would be interesting on these portable SSDs to do real stress testing to see what kind of speed drops occur during heavy write IO. I know with some high-end USB thumb drives heat is a real problem during heavy write IOs that result in the USB throughput dropping.

    why the use of mgx controller instead of mex which is being used in 850evo 1tb model?

    Do all the msata 1tb models use the mgx controller?

    I was hoping for a 70 dollar terabyte one lol

    Just curious … how does this compare with the Freecom mSSD (which I note is not mentioned or reviewed on this website, perhaps because they didn’t wish to sponsor the site?)? I measured the mSSD back in September and it showed very favorably compared to this Samsung device (I used Xbench, so not the identical test conditions). It’s also a lot smaller. But (1) it’s quite expensive (over US$300), (2) only 256MB, and (3) doesn’t have any on-board security (but, for reasons I can’t determine, it performs nearly as fast under Apple’s CoreStorage encrypted volume as it does native).

      What we review and our review of that product has NOTHING to do with advertising and all who are familiar with the site understand that the reviewers opinion stands here.

      I have never even heard of the Freecom mSSD but you are more than welcome to get them to send one along for review if you like.

        Thank you, I will write to them to suggest that. As probably the premier website devoted to SSD topics, I hope that TheSSDReview will interest them enough to send a review sample or two.

        You’ve never heard of FreeCom??? What sort of reviewer are you then? How lazy of you to ask a viewer to get a company to send you a sample. DO IT YOURSELF. THAT’S YOUR JOB.

    Just bought a 1 TB.
    Have you had any issue with exFAT formatting? Samsung talks about lockups.
    Would you recommend reformatting for more stable use on just one OS? User manual recommends reformatting to ONE OS – (NFTS for PC) to avoid write ‘lock-ups’ if you’re going to use only on PC’s.
    I can’t find any instructions from Samsung to reformat the T1 though. Any thoughts would be appreciated. Thanks

    If I remove the mSATA drive from my 1TB T1 and use it as the main drive in my laptop (the one I install Windows on), will Samsung Magician recognize it as an 850 Evo and allow firmware upgrades on it?

    Hi, Do you know if this drive will work with OTG android phones? Many thanks.

    Hi, can you eliminate the bridge from SATA to USB to use it from SATA as Internal SSD?

    Nice review. I have a question on using it for Video editing, I have a regular USB 3.0 on a 4 year old Dell PC (Windows 7 12 GB memory). External HDD is a bit slow, also it often gets failure due to the frequent use of the moving parts on the HDD, Will this SSD solve the problem with no moving part. I do not need a big space for editing as long as it is fast and durable for frequency read/write. Thanks -George

    Can I take it apart and replace the external ssd with the internal ssd i have on my laptop? The internal is also a samsung msata ssd with the same size.

    Just bought a 1TB one and had plans to use it as a super-fast TimeMachine Backup for my MacBook Pro running El Capitan. However, the formatting of it didn’t allow Time Machine Back-ups, so I decided that I could at least use it as my archival hard drive for 20 years of data. Last night I transferred 700GB+ onto it, erased the old external HD, and took it to work.

    However, when I arrived at work, I set up my laptop and plugged in the T1 SSD into the USB keyboard which also had other USB peripherals attached. Imagine my concern to discover that nothing mounted on the desktop when I did so. I unplugged the SSD and tried the USB in the laptop directly as I remembered that some hard drives don’t like to share power with other USB devices from the same port. This is when real horror took hold as only a small partition mounted with only the Samsung software. NO OTHER DATA!

    I logged out and back again and I had trouble holding panic back as I scrambled for the Samsung webchat support. This is when despair set in when they started to ask if I had tried troubleshooting steps including running ANTI-VIRUS software (seriously?) and trying 3rd party data recovery tools. THAT WAS IT – no other data recovery tools recommended. Confidence in Samsung support now completely destroyed and I vowed to never trust Samsung with my data again.

    It was only when I restarted that the SSD data miraculously re-appeared and am now transferring my precious data back to my old HD. I will try to reformat the SSD using the Mac defaults and leave the shonky Samsung encryption to evolve outside my experience.

    Hope this helps somebody else out there.

    How the heck do you open this fandangled thing?
