Problems, parts and running costs

Summary

A pocket USB-C external SSD from Seagate’s 2021 One Touch line, rated for up to 1,030 MB/s over USB 3.2 Gen 2.

Strengths

  • Exact black 1TB tests show about 1,023 MB/s read and 991 MB/s write over USB 10 Gb/s (Tech Advisor).
  • HEXUS and TechRadar 1TB results land near 1,015/963 and 1,047/1,027 MB/s, consistent with a modern 10 Gb/s SSD.
  • exFAT plus both USB cables lets it work across many PCs, Macs and Android devices with no extra power.
  • Toolkit’s Sync Plus can mirror selected folders and optionally archive deleted files.
  • Seagate markets included Rescue Data Recovery Services, with prepaid inbound shipping on eligible drives.
  • Compact at about 43 to 44 g bare, with a removable cable.

Weaknesses

  • The older STJE generation delivers around 400 MB/s, so the part number must be checked carefully.
  • Black STKG1000400 stock is discontinued at B&H and overpriced elsewhere, from $329.99 to $372.99.
  • Short sequential speed does not hold for many small files; one test copied a folder of small files at 107 MB/s.
  • Supplied cables are about 23 cm, awkward for a floor-standing PC.
  • Rescue recovery is not guaranteed and depends on serial-number eligibility.

Full research notes and sources

Which generation this is

STKG1000400 is the 2021-generation black 1TB One Touch SSD, not the slower 2019/2020 STJE1000400 One Touch SSD and not a One Touch hard drive. STKG1000401 is silver and STKG1000402 blue; they are same-generation 1TB color variants. The older STJE model looks similar on a store page but delivers roughly 400 MB/s instead of 1,030 MB/s. Color and part number both matter when matching a listing to this review.

Performance

Independent 1TB tests agree on quick sequential transfers: Tech Advisor measured 1,023 MB/s read and 991 MB/s write on USB 10 Gb/s and about 456/459 MB/s on USB 5 Gb/s; HEXUS measured 1,015/963 MB/s; TechRadar measured 1,047/1,027 MB/s in CrystalDiskMark and copied one 10 GB file in about 18 seconds, roughly 556 MB/s effective. SSD-Tester measured a silver STKG1000401 at 1,052/1,028 MB/s in CrystalDiskMark SEQ1M Q8T1, a folder of many small program files at 107 MB/s, and a few large ISO files at 635 MB/s, with an estimated 24 GB pSLC cache on that sample. Tech Advisor’s sustained-write segment after cache exhaustion ran around 864 MB/s. The 1,030 MB/s figure is a ceiling, not a minimum: on a 5 Gb/s port the same drive lands near 455 MB/s, and hundreds of small files transfer far slower than one large sequential buffer.

Day-to-day use

Both supplied USB cables are about 23 cm, fine for a laptop and awkward for a tower on the floor. The cable is removable, so a compliant longer replacement works, but an unrated USB-C charge-only cable may not carry 10 Gb/s. There is no locking connector, integrated cable or waterproof door, and no IP rating. Seagate’s comparison table gives password encryption to the One Touch HDD but not to this SSD, so sensitive files need OS-level encryption or a different model. A USB 20 Gb/s or Thunderbolt port does not push this 10 Gb/s drive past its interface. Sync Plus is convenient for mirroring folders, but automatic sync is not versioned offline backup; be deliberate about bidirectional changes, the archive folder and excluded file types.

Running costs

Required spend for ordinary removable storage is $0 per year: the drive is bus-powered and has no replaceable battery, filter or other consumable. Optional costs include a longer USB cable, a protective pouch, a second backup drive, paid cloud backup and out-of-coverage data recovery. Seagate’s datasheet does not list validated wattage for this exact model, so a measured annual power cost is not available. For scale only, a hypothetical 1 W average for eight hours a day year-round would be about 2.92 kWh, roughly $0.58 at an assumed $0.20 per kWh; a hypothetical 3 W under the same schedule would be 8.76 kWh, roughly $1.75. These are examples, not measured drive wattages, and exclude host and hub losses.

Is it worth it?

Seagate’s 2021 launch MSRP was $169.99. In October 2026, B&H lists STKG1000400 as discontinued, Micro Center showed $329.99 at one store with another sold out, Staples showed $329.99 out of stock for delivery, CDW showed $372.99 after sign-in, and an independent tracker listed about $329.99 in store and about $357.69 marketplace. Editorial thresholds: below $90 delivered is attractive for someone valuing Sync Plus and Rescue; $90 to $130 is conditional; above $140 to $160, choose newer in-stock models; at about $330, skip. For comparison, Crucial X9 1TB was displayed at $119.99 but unavailable, Kingston XS1000 1TB started around $219.90 from third-party Newegg sellers with a five-year warranty, and Samsung T7 Shield 1TB was $287.99 at Best Buy with IP65 protection, about $42 less than the current Seagate asking price. Neither competitor is proven immune to data loss, but those prices make old Seagate stock a poor value.

Which model this is

This page covers the black 1TB model, STKG1000400, UPC 763649160862, from Seagate’s 2021 One Touch SSD generation. Silver STKG1000401 and blue STKG1000402 are same-generation 1TB color variants, not the exact black retail SKU. Seagate’s support page lists a three-year limited warranty for each 1TB color. Match listings on the STKG part number, because the STJE generation and One Touch hard drives are different products.
