Seagate One Touch Portable SSD 500GB (STJE500400): problems, parts and running costs

Checked: 2026-10-27

Summary

The 2019 USB 3.0 (5 Gbps) STJE500400 (up to 400 MB/s, Micro-B, 500 GB) can fail to be detected after short use, has a short awkward Micro-B cable, and its Sync Plus two-way sync can propagate deletions. No fixed annual parts or subscription cost; electricity is about $0.20 per year in the illustrative 2 W / 500-hour scenario. At $70 or more for new old stock it is poor value next to modern 1 TB USB-C options; under $25 delivered for a tested used unit is defensible.

Common problems and fixes

Complete early failure (not detected) — one verified Best Buy purchaser reported the drive died after copying about 200 GB of Xbox games and less than one week of use, not recognized on the computer despite troubleshooting. Try a known-good Micro-B cable and direct USB port and check OS device management; pursue warranty if eligible, and prioritize professional recovery if the data is the only copy. [13][18]
USB Micro-B cable and port vulnerability — the 20 cm cable is short and the wide Micro-B plug is awkward, so tugging or bending is plausible; replace a suspect cable first and avoid levering the connector. [1][6]
OS cannot mount or detect the drive — Seagate’s support steps cover cable seating, hub topology and port support; safely eject before unplugging and cancel any format prompt if data matters. [16][18]

Parts and consumables

Whole drive (STJE500400) — no user-replaceable internal parts; Seagate does not sell spare controllers or NAND, and an out-of-warranty failed unit is replaced as a whole. [1][17]
Carry case — not included; any padded pouch sized to the 75 x 55.5 x 10 mm body works. [1]
Seagate Toolkit Sync Plus — free download; no mandatory paid license for basic copying. [1][15]

Yearly running cost

No fixed annual parts, subscription, filter, battery or maintenance fee is documented. USB bus power is used only when connected. Illustrative electricity: 2 W at the USB port for 500 connected hours per year is 1 kWh per year, or about $0.20 per year at $0.20 per kWh; those figures are illustrative, not measured on this drive. The main cost exposure is data loss: recovery can exceed the purchase price, and the warranty does not cover data. [1][3][15][17][23]

When it is a good buy

Price thresholds at other stores: DGX Tech about $71.00 in stock (checked October 27, 2026); Walmart Business third-party $109.99; Best Buy and B&H catalog $79.99 but no longer available new; Walmart consumer page $64.72 but out of stock. Newer options: Samsung T7 1 TB advertised at $98.99 but not available for delivery; Crucial X9 1 TB $119.99 at Best Buy but unavailable, or $159.99 in-store-only at Micro Center; STKG500400 successor no longer available at B&H. Value guidance: under $25 delivered for a known-good used unit with a full read/write test is defensible; $25 to $40 is conditional; $50 to $60 leaves little reason to choose this drive; $70 to $110 new old stock is poor value. Alternatives: STKG500400 (1030 MB/s, USB-C) when available; Samsung T7 1 TB; Crucial X9 1 TB. [3][4][7][8][9][10][11][12][21][22][25]
