Samsung T1 1TB SSD review: high speed external SSD

At CES, Samsung introduced a new series of external SSDs, the T1 series. We have tested the 1TB model.

Samsung’s new external SSD is initially mainly because the device is small, light and – as far as objectively determine – is particularly stylish. The T1 weighs 30 grams and measures approximately 7 by 5 inches and is less than a centimeter thick. This thing put in your pocket is really no problem.

The T1 is available in 250GB, 500GB and 1TB capacities, which we have tested the top model. The external SSDs use USB 3.0 and be fully compatible with the UASP protocol that extra fast transfer speeds over USB 3.0 bus is possible. Samsung indicates that transfer rates up to 450 MB / s.

The external SSDs have an integrated 256-bit AES encryption on board. This happens in a very convenient way. When you connect the SSD on a PC with Windows 7 or later or Mac OS X 10.7 or higher is started directly integrated encryption software in the SSD, which you can easily create a password. Have you done that, then the SSD to only approach when you enter that password when connecting the SSD with a PC. The very fact that the encryption software is integrated and you do not need to install software itself makes the encryption very user-friendly.

Samsung T1: Technique

About the technology, Samsung is not very open within the T1 and unfortunately we managed not to open the SSD without damaging it for good. The flash memory is used according to Samsung’s second generation 3D V Nand. Presumably this is controlled on the TLC-way, or with three bits per memory cell, as with the Samsung 850 Evo SSDs. Mind you, this we have been not confirmed. The controller is the “same as the future M.2 versions of the 850 Evo” said Samsung. Probably we have here then do with the so-called MGX controller.

The 250GB version of the T1 must be such as Samsung cost € 199, or € 0.80 per GB. That’s compared with internal SSDs and USB 3.0 memory sticks fairly sharply but given the performance, which further more, in our opinion certainly not too much. We tested 1TB performance must be some cost € 599, or € 0.60 per GB.

With its small size and weight, the Samsung T1 is probably primarily an alternative to fast USB 3.0 memory sticks. Now is a stick in the line of course even smaller and lighter, but as we will see later you get higher performance with the T1 and above are few USB flash drives available in 250GB, 500GB or 1TB. The purpose of the T1 will probably be the same: a user-friendly and easy to carry method to transport large amounts of data between multiple PCs.

Samsung T1: Test results

We tested the Samsung T1 1TB on a system based on an Intel Core i3 processor Haswell, ASRock Z97 Extreme6 motherboard and Windows 8.1 operating system. To be sure that the file copy tests (see below) is not the bottleneck tested drive system have provided an OCZ RevoDrive PCI-Express SSD 350 as a boot disk.

The Samsung T1 is as stated compatible with either the UASP USB Attached SCSI Protocol. These SCSI commands are used to transfer data to and from external storage devices. This higher speeds are achieved than with the traditional USB Bulk-Only Transport (BOT) protocol. Windows 7 does not yet support UASP standard, but most motherboard manufacturers combine special USB 3.0 drivers with their plates to the higher speeds even in this older operating system possible. Windows 8 and 8.1 provide direct support for UASP. Do you have Windows 8 (.1) or Windows 7 with appropriate drivers, then you need to do anything else: controller and connected devices are automatically match or UASP can be used or not and then go to work automatically at the higher speed. But moreover indicates that the T1 Samsung Windows 7 with UASP drivers a fraction performs better due to lower OS overhead, which is something we have not been verified.

Samsung T1: Synthetic benchmarks

First of all, we have rotated some synthetic benchmarks, starting with Atto, which is the throughput assay at different block sizes, each with four I / O-requests at the same time. We see that with 1MB of data blocks the reading speed exceeds 460 MB / s and write speed above 420 MB / s, the promises are thus fulfilled. With 4KB data blocks down the performance just under 100 MB / s.

CrystalDiskMark is due to the fact that tested standard queue depth first (or one parallel I / O request) at somewhat lower, but for external storage is still very high values of: sequential, we arrive at 424 MB / s read and 398 MB / s write. With 4KB data blocks the drive reaches 23 MB / s read and 41 MB / s write.

AS SSD doing similar tests CrystalDiskMark, but with compressible data. The results in the sequential and 4k tests are almost identical, so that we may therefore conclude that the Samsung drive will not benefit at compressible data.

Samsung T1: Real-world benchmarks

The synthetic benchmarks are fun to see where an external SSD theoretically is capable of, the performance in practice of course are the most important. As for external SSDs actually use the same model applies as for USB drives, we use the same test.

First, we tested how long it takes to read 1000 files of 5MB or write. This gives a measure of the performance of a USB stick when you use it for example digital photos or MP3 files. In addition, we tested how long it takes to write a file of 10 GB and read. This indicates how quickly your large files, such as videos, can handle. The performance we have converted to megabytes per second.

Unfortunately, our technique does not allow for products from different product groups (external drives and USB sticks) into the same graph. Hence we can purely below the results of the T1 show:

Reading files the size of digital photos and music files are in practice with 270 MB / s, writing with 250 MB / s. Reading a single very large file comes with 350 MB / s, while writing it comes with 300 MB / s. That’s all very fast.

To put it all in perspective can be found via this link some of the fastest USB flash drives available today. Under Test Results 2015 contains exactly the same test as the Samsung SSD. We then see the quickest results for reading and writing 5MB files about 260 MB / s and 140 MB / s. Especially that last Samsung T1 does so much faster. The highest speeds for the 10GB file is approximately 345 MB / s and 180 MB / s: here the Samsung T1 is mainly in terms of write speed significantly faster.

Samsung T1: Conclusion

The Samsung T1 is a very small and very lightweight external SSD that partly because of its physical properties is actually an ideal alternative to a fast USB memory stick. Quite apart from the fact that few USB sticks 1TB for sale, we have on the previous pages also seen that the performance in any case better than the fastest, we tested USB sticks (although obviously a have lower capacity). Especially in terms of writing excelleerrt Samsung: We measure in practice when copying files up to 300 MB / s! Who often many and / or large files from one to move to another PC, will be very happy with such high performance.

Of course, it will be with a single 2.5 “casing and positioned therein a” normal “SSD still be possible to achieve even higher speeds, then you miss the advantages of the very limited size and light weight.

Wherever we are charmed by the elegant encryption functionality. Precisely because the software is integrated, you do not have to manually install software. Ideal if you want to use the product on many different systems.

The price of € 0.80 to € 0.60 per GB (depending on model) compared with internal SSDs fairly sharply compared with fast USB sticks covered with the giant. For the fastest USB flash drives prices towards or about the euro per GB not uncommon.

All in all we are absolutely excited about the Samsung T1 and we can recommend the 1TB model tested by us warmly.
