Best Budget External SSDs Under $150

TL;DR: The Seagate One Touch 1TB offers 1030 MB/s read/write speeds, a 24 GB pSLC cache, hardware AES‑256 encryption, and a solid software bundle for $132.46.

The standout hardware feature is the 24 GB pSLC cache that helps sustain the advertised 1030 MB/s maximum read and write speeds. With a 1 TB (1024 GB nominal, 931 GiB usable) capacity and a USB 3.2 Gen 2 (10 Gbps) Type‑C interface, the drive can transfer large photo libraries in seconds while keeping data protected with built‑in AES‑256 encryption.

Compared with other SSDs in this roundup, the One Touch is slightly heavier at 0.0992080179 pounds versus the SanDisk Portable SSD’s 0.09 pounds, but matches the Lexar ES3’s weight exactly. Its 70 mm × 50 mm × 10.6 mm footprint is slimmer than the Crucial X9 Pro’s 20 mm height and far shorter than the SanDisk’s 96.9 mm length. Speed‑wise, its sequential read of 1052.13 MB/s outpaces SanDisk’s 800 MB/s and sits just below the SSK SD600’s 2000 MB/s, while its sustained write of 425 MB/s after cache exhaustion falls short of the SD600’s 1400 MB/s but remains respectable for everyday backups.

Users consistently praise the drive’s “stupendous” speed for backing up thousands of photos and its seamless Android backup via the Seagate Toolkit. The four‑month Adobe Creative Cloud Photography Plan and a year of Mylio Create add real value for creatives. However, reviewers note the 14 cm cable feels restrictive, the lack of an IP rating leaves it unprotected against dust or water, and the price's at the higher end of the sub‑$150 segment.

Beyond raw performance, the One Touch’s fabric‑wrapped side and aluminum top give it a premium feel, while shock resistance helps guard against drops. The included USB‑C‑to‑USB‑C and USB‑C‑to‑USB‑A cables, together with a three‑year limited warranty, round out a well‑supported package for portable storage.

Best for: Photographers and videographers who need fast, secure field backup and value the bundled creative‑software suite.

Avoid if: You require rugged, water‑resistant protection or sustained write speeds for massive 4K video editing workloads.

TL;DR: The Crucial X9 1TB delivers 1050 MB/s USB 3.2 Gen 2 performance in a rugged, IP55‑rated, credit‑card‑sized shell for $148.65, earning a 4.5‑star rating from over 6,700 users.

The X9 packs a full terabyte of storage (1 TB) behind a USB 3.2 Gen 2 (10 Gbps) interface, offering up to 1050 MB/s sequential read and write speeds. Its dimensions—0.3937 in (height) × 1.9685 in (width) × 2.55905 in (length)—and a weight of just 0.07054792384 lb (approximately 38 g) make it truly pocket‑sized.

Compared with other SSDs in this roundup, the X9 is a shade heavier than the Transcend Portable SSD (0.06834330122 lb) but lighter than the Lexar ES3 (0.0992080179 lb). It matches the USB 3.2 Gen 2 (10 Gbps) speed of peers like Transcend and Lexar, while offering a slightly higher drop resistance of 7.5 ft (2.3 m) versus Lexar’s 2 m rating. The included USB‑C to USB‑C cable measures about 9 in (229 mm), which some users note is shorter than they’d prefer.

Consumer sentiment is overwhelmingly positive, reflected in a 4.5‑star average from 6,773 reviews. Reviewers repeatedly praise the rapid file transfers, feather‑light feel, and IP55 water, dust and sand resistance. A few owners have reported occasional units that fall to much slower speeds and isolated cases of SSD corruption after roughly a year of use, which professional reviewers cite as a trade‑off for the budget price point. The drive draws power from the bus, pre‑formats in exFAT, includes 256‑bit AES hardware encryption, and adds three months of Mylio Photos Plus plus Acronis True Image software, and comes with a three‑year limited warranty.

TL;DR: The SSK Portable SSD 500 GB delivers up to 1050 MB/s reads and 1000 MB/s writes in a 2 mm‑thin, aluminum‑cased package that weighs just 84.4 g, making it a fast, pocket‑sized option for budget‑focused users.

SSK’s standout spec is its NVMe PCIe x4 core paired with a USB 3.2 Gen 2 (10 Gbps) interface, which the manufacturer lists as achieving up to 1050 MB/s sequential read and 1000 MB/s write speeds. The drive sits in an aluminum alloy shell that’s only 2 mm thick, measures 37.5 mm × 68.5 mm × 12.6 mm, and draws less than 2.4 W, so it runs entirely off the host’s bus power. With an advertised 500 GB capacity (≈465 GB usable on Windows) and a 25 % SLC cache (~125 GB), it targets quick bursts of data movement while staying under the $150 budget ceiling.

Compared with the other thirteen SSDs in this roundup, the SSK is a bit heavier than the Verbatim 256 GB model (which weighs about 0.022 lb) and the SSK SD450 (43 g), but it still stays under 0.2 lb at 84.4 g. It’s thicker than the Seagate One Touch SSD 500 GB’s 9.9 mm height, yet its overall profile is slimmer thanks to the 2 mm thickness. In terms of speed, its 1050 MB/s read matches the top‑tier Crucial X9 Pro 1 TB and slightly exceeds the 1030 MB/s read of the Seagate One Touch SSD, putting it on par with the fastest options while offering a lower price point.

Reviewers consistently praise the drive’s compact metal build, noting that the aluminum case helps keep temperatures down during intensive transfers. The inclusion of both USB‑C‑to‑C and USB‑A‑to‑C cables earns extra points for cross‑platform convenience, and reviewers highlight the plug‑and‑play experience as hassle‑free. Mobile creators especially like the iPhone 15/Pro 4K ProRes support. On the flip side, users point out the absence of a Lightning‑to‑USB‑C cable, which means an extra purchase for direct iPhone connections. The 25 % SLC cache also means sustained large file moves can taper off once the cache fills, a nuance power users note.

Best for: Budget-conscious buyers seeking a reliable entry-level option

Avoid if: You need advanced features or professional‑grade performance

TL;DR: The SanDisk 1 TB Portable SSD packs 800 MB/s read speeds, IP65 dust‑and‑water resistance, and 2 m drop protection into a feather‑light 40 g, $133.82 drive.

SanDisk markets this drive with a sequential read speed of up to 800 MB/s and a sequential write speed of up to 796 MB/s, delivered over a USB 3.2 Gen 2 (10 Gb/s) interface. At just 0.09 pounds (40 g) and only 9.91 mm thick, it’s one of the most portable SSDs in the lineup, and the IP65 rating plus a 2 m drop‑protection rating give it a rugged edge for on‑the‑go creators.

Compared with the other 13 options, the SanDisk is lighter than the Seagate One Touch 1 TB (≈0.099 pounds) and the Lexar ES3 (≈0.099 pounds), and its 9.91 mm height is slimmer than Seagate’s 10.6 mm. Its 800 MB/s read speed sits below Seagate’s 1030 MB/s and Lexar’s 1050 MB/s, but it outpaces the entry‑level SSK Portable SSD’s advertised 550 MB/s. The included 12‑in USB‑C to USB‑A cable is longer than Seagate’s 14 cm cable, yet still shorter than many users would prefer.

Reviewers consistently praise the drive’s quick transfers, compact form factor, and rugged design—especially the rubberized loop that lets you clip it to a belt or backpack. Professional reviewers list real‑world reads around 892 MB/s, exceeding the 800 MB/s spec, and they've also flagged speed variability on older ports. Common complaints focus on the short USB‑C to USB‑A cable, the stiff rubber loop, and users often report write speeds below 500 MB/s, which may disappoint heavy upload tasks.

TL;DR: The Verbatim 256 GB Portable SSD costs $32.48, offers up to 625 MB/s transfer speeds, and weighs just 0.0220462262Pounds, making it the cheapest lightweight SSD in the $150‑budget tier.

The drive’s headline spec is its theoretical 625 MB/s transfer speed over a USB 3.2 Gen 1 (5 Gbps) connection, paired with 0.256 TB (256 GB) of storage. At a price of $32.48 and a weight of 0.0220462262Pounds, it's the most affordable and lightest option among the fourteen SSDs we examined.

Compared with peers, the Verbatim SSD is significantly lighter than the SSK SD450 (0.09479877266pounds) and the SSK Portable SSD 500GB (0.186070149128Pounds), and also lighter than the Seagate One Touch 500GB (0.1543235834pounds) and Seagate One Touch 1TB (0.0992080179pounds). Its USB 3.2 Gen 1 interface (5 Gbps) is slower than the SSK SD450’s 6 Gbps and the SSK Portable SSD 500GB’s 10 Gbps, but its 625 MB/s speed outpaces the SD450’s 550 MB/s read and 500 MB/s write claims. It falls behind the higher‑end peers that list read speeds of 1,030 MB/s or more, such as the Seagate One Touch 500GB and the Crucial X9 Pro 1TB.

Reviewers consistently praise the compact size and the noticeable speed jump over traditional HDDs, noting that the drive feels “ultra‑slim” and is easy to slip into a laptop bag. However, several users report that real‑world transfers sometimes miss the 625 MB/s mark, and some describe the plastic‑plus‑aluminum enclosure as “flimsy” compared with metal‑cased rivals. The base model also lacks hardware encryption, and the bundled Nero backup software is Windows‑only and some regard it as dated, which can be a drawback for Mac users.

Beyond performance, the SSD is bus‑powered via a USB‑C port and includes a USB‑C‑to‑USB‑A cable plus an adapter, so you don’t need an external power brick. Verbatim backs the unit with a 2‑year limited warranty, adding a modest safety net for a budget‑focused purchase.

Best for: Shoppers on a tight budget who want the most for their money

Avoid if: You need hardware encryption or rely on Mac‑specific backup tools

It also carries a 600 TBW endurance rating and a 25% SLC cache, while sustaining about 1400 MB/s on large transfers. At just 10 mm tall and 33.8 g, the aluminum alloy enclosure keeps the unit cool under load, with an operating temperature ceiling of 50 °C and power draw under 4.7 W.

Compared with the other 13 SSDs in this sub‑$150 roundup, the SD600 is lighter than the Oscoo 1TB (48.3 g) and Lexar ES3 (45 g), and only a few grams heavier than the SanDisk Portable SSD (40 g). Its 10 mm height matches Lexar’s but is slimmer than Oscoo’s 12.6 mm profile. Speed‑wise, it ties Oscoo’s 2000 MB/s read claim, while outpacing SanDisk’s 800 MB/s read rate. The $139.99 price places it toward the higher end of the budget segment, yet its feature set remains competitive.

Users consistently praise the SSD’s “lightning‑fast” file transfers and the way the aluminum body stays cool during 4K ProRes video recording. Professional reviewers highlight the SLC caching algorithm and the solid thermal design as reasons the drive maintains high speeds. The most common complaints focus on the fact that full 2000 MB/s performance only appears on USB 3.2 Gen 2x2 ports and that the included cables are relatively short. Reviewers also note the lack of a rugged or waterproof rating, which some competing models provide.

Best for: Content creators needing rapid 4K ProRes recording on a compact, well‑reviewed SSD.

Avoid if: You need a rugged, waterproof drive or rely on older USB ports for maximum speed.
