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


Perhaps the most valuable piece of advise we can offer if you are considering disassembly of the T1 is …DON’T DO IT!  Personally, I love taking things apart and have been doing it for years and, given this love of ripping things apart, it is only natural that things sometimes just don’t go right, especially with Samsung SSDs.  We don’t need to speak of a certain 840 Pro where the pentalobe screw didn’t want to cooperate, resulting in my punching a hole clear through that SSD.

The Samsung Portable SSD T1 is comprised of five pieces, three being the plastic exterior, a mSATA to USB3.0 bridge, and a Samsung 850 EVO 1TB mSATA SSD.

The exterior plastic case is secured by clips of which there is no easy way to get them apart, short of a great deal of frustration.

The SSD itself consists of a green printed circuit board, a low power 2-core MGX controller (S4LN062X01-Y030), four pieces of Samsung 3D V-NAND flash memory with a product number of K9DMGB8S7C, and a Samsung DRAM cache memory chip.

Last but not least, we have the mSATA to USB3.0 adapter which contains the ASMedia 1153e USB3.0 controller with UASP support.

Now, looking back at my improvised Samsung 1TB external SSD that was created some time ago, we can see that things are surprisingly very similar in build; this original design being a MyDigitalSSD OTG case housing the Samsung 1TB 840 pro mSATA SSD.

    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.
