What Is a Good External Ssd Read/write Speed
The all-time portable SSDs in 2022: super-fast and super-convenient on-the-go storage
Included in this guide:
If all your shooting is fast filling your computer's storage – or yous need to continue your digital portfolio portable – then information technology'due south time to invest in one of the best portable SSDs. A conventional portable hard disk drive still offers the most bytes for your buck, but for elevation transfer speeds, a solid land drive (SSD) is a must. The best portable SSDs are too a fraction of the size and weight of a conventional portable hard drive, and though an SSD's speed and portability notwithstanding commands a premium over a hard drive, pricing is now much more accessible for storage space up to 1 terabyte.
Rather than testing transfer speeds using unrealistic benchmarking software, we instead recorded maximum sustained read and write rates when shifting photos and video to and from a Windows ten PC packing a fast internal m.two SSD and Thunderbolt iii connectivity to ensure no testing bottlenecks.
The all-time portable SSDs in 2022
This is non SanDisk's top-of-the-range portable SSD - that accolade currently goes to the Farthermost Pro Portable SSD V2 (see further down this list), just this cheaper not-Pro version is still the one to go for. That's because almost no computer currently bachelor tin fully exploit the actress speed offered past the Farthermost Pro, and then in existent-world use it'south barely faster than this SSD.
SanDisk quotes a peak read speed of 1050MB/s for the Extreme Portable SSD. Nosotros were able to verify this claim with the CrystalDiskMark storage benchmark app, though achieving such speed in real-world file transfers is unlikely. Despite testing with a blazing fast laptop, we could 'only' manage a peak 780MB/south when reading a large video file (a best-case scenario) and 564MB/south when writing information technology to the bulldoze. However, that'southward hugely fast, and image transfer speeds of 693/496MB/s read/write are equally incredible. It should as well exist noted that a portable SSD will rarely - if always - perform equally fast in actual file transfers as in a software criterion.
Capacities come in 250GB, 500GB, 1TB and 2TB, but it'southward the 500GB option that makes well-nigh sense unless you definitely need more space, equally prices pretty much double in line with capacity.
This is WD'south latest version of its pop MyPassport SSD, not to be confused with the previous incarnation which is still on auction. The new version has a smoother, more than rounded pattern, but while it looks unlike, it still goes past the verbal same My Passport SSD proper name, just for that little extra confusion.
We weren't all that impressed with the speeds we got from the old My Passport SSD, merely this new one is built around NVMe SSD technology and promises to be near twice as fast, with advertised max read/write speeds of 1050MB/s and 1000MB/s respectively. And refreshingly we found WD'south claims to exist bang-on, as CrystalDiskMark measured 1041MB/south and 1002MB/s read/write rates - very impressive. Switching to existent-earth testing inevitably brings a performance striking, but the new My Passport SSD notwithstanding performs well. We accomplished an boilerplate 651MB/due south and 569MB/s read/write speed with video files, and 538/364MB/south with multiple epitome files. These are marginally faster results than the SanDisk's superb Extreme Pro Portable SSD, apart from the epitome write speed where the My Passport SSD was near 30% slower.
Capacity options include 500GB, 1TB and 2TB, with connectivity being via USB Type-C 3.2 Gen two. A USB-C to USB-A adapter is included in the box.
With its removable rubberized bumper and bombproof build quality, it's no surprise that the rock-solid Envoy Pro EX boasts military-grade MIL-STD810G drop protection. Still, all this ruggedness does have a downside: bulk. At 14.5 10 7.4 x 2.3cm and 300g with the bumper in identify, this drive is positively gargantuan next to rival Sandisk or WD portable SSDs, and it even outsizes the power brick for our high-stop testing laptop.
So information technology'd better have plenty of operation to compensate. Thankfully, with NVMe SSD engineering and a Thunderbolt 3 connection promising a theoretical 40Gbps bandwidth (that's 4x faster than USB 3.1 Gen ii), the Envoy Pro EX has all the right ingredients for winning performance.
CrystalDiskMark gets things off to a good start with stunning peak sequential read/write speeds of 1440/726MB/southward respectively, though this is some way short of OWC's merits of "upwards to 2800MB/due south". Existent earth file transfers will e'er exist slower than a synthetic benchmark test, but we still recorded a hugely impressive 995MB/southward tiptop read speed when shifting 1 massive video file, though this figure did drib as the transfer progressed, leaving the final averaged video read speed at a more modest - though still very rapid - 645MB/south. An average 612MB/s read speed moving multiple prototype files is also superb, though write speeds accept a significant performance hit, with an average 481MB/s when writing video and only 278MB/s when writing multiple images. That paradigm write rate did elevation at a healthier 413MB/due south during the transfer, merely the drive couldn't sustain this speed, hence the slower average effigy.
The Envoy Pro EX is bachelor in 460GB, 1TB, 2TB and 4TB capacities - the latter beingness unusual amidst portable SSDs, and ideal if y'all need to keep 4K or even 8K video content backed up and mobile.
Until recently this drive was known as the Chiliad-Drive Mobile SSD R-Series, and may still be called this at some retailers. Its standout feature is its ruggedized design that protects the drive against a iii-metre drop and 1000lb of crushing forcefulness, plus the exterior is IP67 rated to resist dust and moisture. Despite this extra exterior protection, the drive's 95mm x 50mm ten fourteen.5mm dimensions are merely marginally more than bulky than the non-ruggedized WD My Passport SSD.
Inside the toughened shell is a fast SSD which G-Technology claims can transfer data at upwardly to 560MB/s - impressive stuff. The drive connects via an up-to-date USB three.1 Gen ii Type-C connection, though a Type-A converter is included to maintain compatibility with older computers.
Though we couldn't quite lucifer the drive's claimed 560MB/s max transfer speed, we did clock it at a very respectable 410/353MB/south when reading/writing video. Image transfer speeds of 307/298MB/s read/write are too hugely impressive. Factor the five-year warranty and this drive has every base covered.
Samsung's entry is as sleek every bit portable SSDs come up, with a simple matte aluminium casing that oozes understated quality. Measuring only 74 ten 57.3 ten x.5mm, it hands slips into a shirt pocket, and in that location are even four colour finishes: black, blueish, gilt and cerise. Yous might not guess information technology from the fashionable exterior, but the SSD T5 is also rated to survive a 2-metre drop, and your information can exist protected by 256-bit hardware encryption. 500GB, 1TB and 2TB chapters options are bachelor, with the 1TB version being specially practiced value, costing lilliputian more than than many rival 500GB drives.
Hook up the USB 3.1 Gen ii connection (Blazon-C and Blazon-A cables are supplied) and, while the advertised 540MB/southward transfer speed will be tough to achieve, you lot're notwithstanding bodacious stellar speeds. We recorded baking 415/365MB/s rear/write speeds when transferring video, and epitome read/write speeds of 308/298MB/s are equally mighty.
Lexar is a brand usually associated with peak-notch memory cards and card readers, but it also offers several portable SSDs. The SL200 is its latest offering, and measures an easily portable 86 ten threescore x 9.5mm. Build quality feels reassuringly solid, and the matte silver terminate looks the part next to most modern laptops.
Lexar advertises maximum read/write speeds of 550/400MB/s, which is fairly typical for a non-NVMe SSD. We clocked the drive at a maximum 448/289MB/s when reading/writing a single large video file - a best-case existent-globe speed scenario. Transferring large quantities of small epitome files inevitably slows whatsoever SSD down, but the SL200 still managed a reasonable 384/267MB/due south read/write. These speeds are broadly comparable to the similarly-compact Samsung SSD T5, however that SSD does tend to be cheaper than the Lexar when comparing equivalent capacities.
The Lexar SL200 tin be had in the popular 512GB, 1TB and 2TB capacity options, and connects via a USB 3.one Blazon-C port on the drive. USB Type-C to Type-C and Type-C to Type-A cables are included in the box.
If you're after a seriously slim SSD, this offering from Transcend is just the ticket. Measuring a mere 7.5mm thick, it'due south appreciably thinner than a typical portable SSD, and though longer than most at 120mm, information technology'southward simply 33.6mm wide. The matte aluminum outer casing too looks the office, with its space-grey finish especially complementing Apple products.
With the assistance of Transcend's bundled Aristocracy software, the drive tin can be formatted for Windows or Mac, or you lot can connect it direct to an Android mobile device that supports USB On-The-Get. USB Type-C to Type-C, along with a Type-C to Type A cable are included to let connectedness to desktop, laptop or phone.
The drive utilises a modern USB 3.1 Gen ii interface. Its ten Gbit/s speed rating is easily plenty to max out the drive's claimed 520MB/due south max read and 460MB/s max write rates. We actually accomplished even faster read/write speeds of 564/476MB/southward in CrystalDiskMark, though as is almost ever the case, real-globe speeds were a scrap lower in our testing. When transferring multiple images and a single large video file, the ESD250C managed 464/328MB/s video read/write speeds, and 327/305MB/south read/write when shifting images.
When it comes to chapters, you tin can have any size you desire, as long equally it's 960GB. However despite there being no smaller pick, pricing is very competitive, in line with most manufacturers 500GB SSDs.
The My Passport SSD is certainly 1 of the more fashionable portable SSD's on the marketplace, with its part metal-effect casing and svelte ninety ten 45 x 10mm size likewise making this 1 of the smaller portable SSDs you can purchase. Information technology's available in 256GB, 512GB, 1TB and 2TB capacities, with the 512GB version currently beingness the price/capacity sweet spot at £80. The USB 3.1 Gen 2 Blazon-C connection ensures fast transfer speeds, and for computers that lack a Type-C port, WD includes a Type-C to Type-A adapter in the box.
Performance is overall very proficient, but not quite upward there with the best. Nosotros clocked the My Passport SSD at a very healthy 392MB/s when reading a single large video file, though a 201MB/southward video write rate is much more pedestrian. Likewise, 234MB/s read and 198MB/due south write speeds when transferring multiple image files, while perfectly acceptable, is nothing special.
The SanDisk Extreme Pro Portable SSD V2 is really SanDisk's flagship portable SSD, boasting read/write speeds up to 2000MB/due south - that'southward nearly twice as fast as the non-Pro version (some retailers aren't using the 'V2' designation though, then wait out for the 2000MB/due south performance rating to ensure you're getting the right SSD version).
And so if this is such a blazing fast portable SSD, why isn't it further upwards our list?
Well, in our testing, we found real-world read/write speeds to be only marginally faster than the regular SanDisk Extreme Portable SSD V2. That's considering the Farthermost Pro V2 requires the unusual 20Gb/southward USB iii.ii Gen 2x2 interface (side note - oh how I'd love to encounter whoever came up with the illogical USB numbering system!) which allows for transfer speeds upward to 2000MB/s. However, since in that location are nigh no computers that currently have USB 3.ii Gen 2x2 ports, you lot'll notice transfer speeds limited to 1000MB/s, equally was the example with our test estimator. The CrystalDiskMark storage benchmarking app confirmed this, with max read write speeds of 1049/1032MB/s - most the exact speed limit of our USB iii.2 Gen ii connection - and a long way curt of the 2000/2000MB/s max speed on the box.
And so with this in mind, at that place really isn't much point spending the price premium for this Pro version over the non-Pro Extreme V2 portable SSD. There is one exception: USB 4 is being incorporated into the latest computers, and it's backward compatible with USB 3.two Gen 2x2, so a estimator with USB 4 will unleash the full speed of the Farthermost Pro Portable SSD V2.
On the 1 hand, this is a typical - if relatively large - portable SSD available in 250GB, 500GB, 1TB and 2TB capacities. Information technology's capable of reasonable 350/285MB/southward read/write speeds during sustained video file transfer, while folders of images shift at an equally rapid 290/256MB/s.
But this is much more than but an SSD. Information technology's too a device designed to exist used equally stand up-alone storage in the field, then during a shoot you tin can dorsum upwardly images from your memory carte du jour without needing a computer. This is made possible by the Passport's built-in SD card reader.
In one case your shots are on the bulldoze, you tin can then view them on your smartphone or tablet, as the Passport also acts as a wireless media server with its Wi-Fi hotspot. Even Raw images stored on the drive are viewable, and the device can wirelessly stream 4K video.
Powering all this is a born battery good for up to x hours continuous use, and if you don't need all-day ability, the bombardment can also double as a half-dozen,700mAh ability banking concern.
The only drawback with the device is its size, as at 135mm-square and 30mm thick, it's bulky past SSD standards, though yous can remove the soft rubber bumper to shed a few millimeters if you can manage without its shock protection.
Five things to look for in a portable SSD
1. Bounce back
Conventional hard deejay drives use sensitive moving parts, but non SSDs, making them much less vulnerable to drops.
2. Formatting: Mac or Windows?
Some drives are pre-configured for either Mac or Windows. This tin can almost always be inverse with the right software.
iii. Experience the speed
Don't expect even an SSD to transfer a big batch of image files as fast equally it'll shift a single video file of the aforementioned size.
4. Well connected
All portable SSDs are powered past their USB connection, so don't crave a split up ability brick.
5. Petty extras
Many manufacturers also bundle extras like backup software, data encryption, or even complimentary deject storage.
