Samsung is the primary producer to supply an reasonably priced exterior SSD with 8 terabytes of storage. The T5 Evo isn’t the quickest, however provides strong velocity for the reminiscence dimension.
20 years in the past, particular person SSDs provided 8 gigabytes of storage at greatest. Samsung’s T5 Evo now provides as much as 1000 occasions extra – and in a compact, transportable kind. Even my 2018 NAS has much less storage.
In the event you want plenty of space for storing, the T5 Evo is an effective answer. However you want extra endurance than with different present exterior SSDs. It can’t sustain with the switch velocity due to the previous SATA normal.

Right here you will discover all T5 Evo fashions.
The Samsung T5 Evo intimately
The T5 Evo is obtainable in storage sizes of two, 4 and eight terabytes (TB). At 40 × 95 × 17 millimeters, it’s compact – 8 TB in your pocket, so to talk. The SSD weighs 102 grams, about as a lot as a bar of chocolate. In comparison with different SSDs, that is comparatively excessive.
The exterior SSD is reminiscent of a big USB stick. This impression is strengthened by the eyelet with which you’ll connect the T5 Evo to a keychain, for instance. The SSD is roofed in rubber, however doesn’t provide any safety towards mud and water. Nevertheless, Samsung claims a drop resistance of two meters.
The SSD is linked on each side by way of USB-C. An adapter for USB-A isn’t included within the scope of supply. Total, the T5 Evo is properly made.

Samsung doesn’t specify which controller is within the exterior SSD. Samsung makes use of 176-layer QLC for 3D NAND reminiscence. NAND is a non-volatile reminiscence expertise that doesn’t require energy to retailer information. QLC stands for “Quad Degree Cell”. 4 bits are due to this fact potential per reminiscence cell. SSDs with this sort provide plenty of space for storing, however are slower than these with fewer bits per reminiscence cell. The SSD provides AES 256-bit encryption. The restricted producer’s guarantee is three years.
In response to the producer, the switch charges are 460 megabytes per second (MB/s) for studying and writing. Samsung makes use of SATA as an alternative of NVMe expertise for this SSD. That is why the switch charges are considerably decrease than, for instance, with the Samsung T9. To realize these speeds, you should join the SSD no less than by way of USB 3.2 Gen1 (previously USB 3.0).
Sequential write and skim velocity within the ATTO Disk Benchmark
Information saved sequentially is saved in contiguous blocks. Because of sequential studying and writing, you’ll be able to estimate how briskly the SSD is when accessing massive multimedia recordsdata, transcoding movies or watching movies. Producers wish to specify sequential speeds as a result of they’re the best.
I do all assessments on my check system with the next parts:
400.54
AMD Ryzen 9 7900X
AM5, 4.70 GHz, 12 -Core
108.67 108.67/1TB
Essential P5 Plus

Within the following graphic you’ll be able to see the ends in comparability with exterior SSDs which have already been examined. For the sake of readability, I’ve not built-in all the outcomes into the graphic. You see the utmost measured outcomes.
The ATTO Disk Benchmark makes use of uncompressed information. It assessments the learn and write efficiency of assorted switch sizes from 512 bytes to 64 megabytes throughout sequential studying and writing.
At 448 MB/s, the T5 Evo doesn’t attain the said most learn velocity of 460 MB/s. That is the case with nearly all SSDs, as these are theoretical specs that may solely be achieved beneath optimum circumstances. In comparison with the opposite SSDs, the distinction between promised and precise efficiency is sweet. With the said write velocity of 460 MB/s, it’s even additional off at 430. The exterior SSD solely develops its full learn and write velocity from a file dimension of round 12 megabytes (MB).
Compared to the opposite SSDs examined, the T5 Evo falls brief. However this isn’t shocking given the connection normal and SATA expertise.
Random entry and extra on sequential velocity
Whereas the MB/s worth is central to sequential studying and writing, the enter and output instructions per second (IOPS) are essential to random writing. The upper the IOPS values, the quicker the SSD. The shorter the response occasions, the quicker the SSD reacts. “Random studying and writing” refers to information that isn’t saved in contiguous reminiscence cells. They’re randomly distributed on the SSD.
The Anvil’s Storage Utilities benchmark not solely reveals learn and write speeds, but additionally details about IOPS and response occasions. The benchmark assessments the velocity of random accesses of various sizes. This benchmark can be utilized to estimate how briskly SSDs are when booting, loading purposes, or looking for saved recordsdata. From the assessments, the benchmark creates a rating for studying and one for writing.
The T5 Evo achieved the worst end in Anvil’s Storage Utilities. For the explanations already talked about above, this isn’t shocking. The exterior SSD depends on storage amount and never velocity.
Sensible check: transferring recordsdata
To check the efficiency of the SSD in real-world eventualities, I copy varied recordsdata from the system drive to the T5 Evo. Beforehand, I format the SSD within the exFAT file system and let it relaxation for half an hour.
First up is a 101 GB file folder with MP4, RAW pictures and a Premiere Professional venture – 60 recordsdata in whole. The Evo T5 wants 287 seconds for this. It is a strong efficiency, particularly because the switch fee averages 350 MB/s. A most of 390 MB/s is feasible. That is nonetheless lower than the said 460 MB/s, however no less than the SSD is constant.
That is additionally what my additional check reveals. I always copy the identical folder to the SSD and report the switch fee. That is all the time between 300 and 390 MB/s as much as 60 % fill stage. Solely then does it drop under 300 MB/s and attain the utmost of 390 MB/s much less typically. Nevertheless, as soon as the fill stage reaches 75 %, the switch fee drops to under 100 MB/s. On common it ought to be 55 MB/s.
Throughout your entire copying course of, the temperature of the SSD is a most of 46 levels Celsius. So it stays good and funky. It would not get uncomfortably sizzling outdoors both. Earlier than I do the subsequent check, I format the SSD and let it relaxation for half an hour.
For the subsequent check, I am going to copy a ten GB file folder with MTS, MP4, MP3, MOV and JPEG recordsdata in addition to one other Premiere venture – over 100 recordsdata in whole. Once more, the T5 Evo isn’t as quick as different SSDs, however it’s constant. The switch takes 25 seconds. The switch velocity is between 280 MB/s to 380 MB/s. The truth that it’s decrease than within the first check is because of the a number of small recordsdata. Random entry has a better impression.
It comes into play much more within the final check. The virtually 4 GB file folder comprises greater than 160 pictures in RAW format. The T5 Evo takes 12 seconds to switch – a decent consequence. The switch fee is between 230 and 280 MB/s.
If I copy information from the T5 Evo to itself, the write fee is 200 MB/s when it’s empty. If the SSD is at 75 %, it’s only 50 MB/s.
Conclusion: Excellent for storing a lot of information
In case you are not pressed for information switch and depend on 8 terabytes of storage, the Samsung T5 Evo is an effective alternative. Principally the one one, as a result of the competitors lacks something comparable – besides maybe HDDs. They’re bigger and solely provide round a 3rd of the velocity of the T5 Evo. In distinction to fashions with much less reminiscence, the SSD is sluggish, however no less than it could possibly preserve its low velocity as much as 75 % capability.
If 4 terabytes of storage is sufficient for you, you are higher off utilizing the Essential X6. It is cheaper and quicker. Or you’ll be able to construct an exterior SSD your self from a case and an inside SATA drive. Then there’s 8 terabytes of storage for much less cash. However the half is larger.
