Have you ever heard of Buffalo Co., Ltd.’s transportable SSD sequence “SSD-PSTU3-BA”, which boasts the smallest and lightest measurement?
This product claims to be the corporate’s smallest ever USB flash reminiscence sized SSD (14.6 x 8 x 28 mm). The size of the protruding half when connected to a USB port is roughly 17 mm, which is shorter than the diameter of a 1 yen coin. It additionally weighs roughly 4.5g, which is lighter than 5 1-yen cash.
SSD-PST1.0U3-BA
An SSD that is rather like a USB flash reminiscence
There are three sorts within the lineup: 250GB (SSD-PST250U3-BA), 500GB (SSD-PST500U3-BA), and 1TB (SSD-PST1.0U3-BA). The 250GB and 500GB fashions have been launched in early September. The 1TB mannequin was launched in late November.
The recommended retail value is 6,600 yen for 250GB, 10,000 yen for 500GB, and 18,800 yen for 1TB (all costs embrace tax).
The value vary for a 2.5-inch inside SSD (1TB) is round 7,500 yen to 9,000 yen, so it feels costly, however it’s comprehensible when you think about the large benefit of being the scale of a USB flash reminiscence.
Connected to the pocket book PC.It seems to be like a USB flash reminiscence reasonably than an SSD.
It is because any such product is designed for use with out being plugged in. The producer’s suggestion is to be used with stationary recreation consoles and TV recording. Particularly, even when wall-mounting a flat-screen TV, the protruding half is brief at roughly 17mm, so there’s a excessive risk that it may be used as is.
So, what if this can be a laptop computer for work? If you happen to retailer it in a case and carry it round, you’ll in all probability select a case that’s the good measurement, so even when the protruding half is as brief as 17mm, there could also be circumstances the place you can not retailer it.
If you do not have sufficient area for the case, it is best to keep away from utilizing your laptop computer with it connected. Nonetheless, it is usually true that the brief protrusion part is extraordinarily advantageous for work pocket book PCs.
For instance, knowledge corruption as a consequence of unintentional contact. This stuff are more likely to be preventable. Within the case of a conveyable SSD outfitted with a so-called 2.5-inch SSD, because the predominant physique is on the finish of the cable, knowledge issues are more likely to happen as a consequence of unintentional contact reminiscent of being dropped or being pulled.
If this can be a USB flash reminiscence kind with a protrusion of roughly 17 mm, such accidents may be decreased.
The protruding half is shorter than a 100 yen coin.
The connection interface makes use of USB 3.2 (Gen 2) USB Kind-A. Contemplating the present state of PCs, I would really like it to assist USB Kind-C, however when contemplating connections to recreation consoles, TVs, and so forth., USB Kind-A continues to be the proper format.
Even when contemplating operation with a pocket book PC, USB Kind-A is bigger than USB Kind-C by way of the scale of the connection port, so it’s going to in all probability permit for a extra steady connection. In keeping with the producer, the adoption of USB Kind-A additionally takes warmth dissipation into consideration.
As well as, the principle physique complies with the US MIL normal “MIL-STD-810H 516.8 process IV”. The corporate performed a take a look at during which a take a look at pattern was dropped from a top of 122 cm in a complete of 26 instructions, together with all sides, faces, and corners. It’s stated that inside 5 take a look at samples, normality was confirmed in all 26 instructions of drops.
In that sense, it may be stated that it’s a transportable SSD that can be utilized with peace of thoughts.
Passable switch velocity
The nominal most switch velocity is roughly 600MB/s for studying and 500MB/s for writing.
When utilizing the benchmark software program “CrystalDiskMark”, when the info measurement is “1GiB” (GiB = Gibibyte, binary prefix), sequential entry (SEQ) learn and write instances are roughly 628MB/s and 634MB/s. The consequence was greater than the nominal worth. Random entry (RND) additionally has first rate outcomes, with learn speeds of roughly 238MB/sec and writes of roughly 258MB/sec.

After that, I attempted altering the info measurement to “4GiB”, “8GiB”, and “16GiB”, however the numbers didn’t change a lot.
Benchmark outcomes when knowledge measurement is 4GiB
Benchmark outcomes when knowledge measurement is 8GiB
Benchmark outcomes when knowledge measurement is 16GiB
Nonetheless, when the info measurement was set to 32GiB and 64GiB, a big drop in efficiency was noticed.
When the info measurement is 32GiB, sequential entry is roughly 178MB/sec for studying and roughly 580MB/sec for writing. As for random entry, it may be seen that the efficiency has considerably decreased, with reads being about 133MB/sec and writes being about 160MB/sec.

Talking on the premise that this can be a pre-release rental system, when this product was left plugged into the USB port (about 6 hours after startup), the temperature was round 60 levels. On account of making use of a load on this state, the temperature rose to 79 levels. As a result of these components, it’s thought that so-called thermal throttling was activated as a warmth countermeasure.
The temperature rose to 79 levels, in all probability as a consequence of lengthy use and excessive load.
The corporate shops the self-diagnosis perform “SMART” (Self-Monitoring, Evaluation and Reporting Know-how) info of exterior SSDs within the cloud, and gives a failure prediction service “Mimamori Sign” that grasps the well being standing of the SSD. Since this product can be suitable, it’s a reassuring level to have the ability to rapidly discover out about any abnormalities within the product.
As well as, we additionally provide the file copy speedup software “CopyBooster” (Home windows), which may be anticipated to scale back knowledge copying time.
Though the principle unit itself will not be characterised by extraordinarily excessive velocity, I get the impression that it’s extra user-friendly by being suitable with these providers and software program.
abstract
“SSD-PSTU3-BA” is a conveyable SSD that appears like a USB flash reminiscence at first look.
Because the protruding half is brief at roughly 17 mm, it could be potential to think about including storage for pocket book PCs that should not have expandability.
Fairly, it may be used as a working storage system, basically a conveyable SSD that can be utilized between a number of PCs, reminiscent of a pocket book PC outdoor and a desktop PC indoors.
Talking of greed, I would be pleased if it helps “USB 3.2 Gen2x2” (most switch velocity: 20Gb/s), but when it prices an excessive amount of, will probably be troublesome to buy, so I assume it is a good suggestion.
In any case, a product this small and straightforward to deal with is welcome. It will be good if there was a terminal cap for carrying it, however I ponder if it is okay if I haven’t got to maintain it on. What do you suppose?
