That is an encouraging result—but not a blanket guarantee of invulnerability. The useful takeaway for PC owners lies in separating what happened to this particular drive from what SanDisk actually promises.
What the durability test involved
Fatmi tested a Sky Blue drive identified as SDSSDE61-2T00. SanDisk’s product listing identifies the corresponding 2TB Sky Blue variant as SDSSDE61-2T00-G25B and specifies USB 3.2 Gen 2 connectivity, IP65 water and dust resistance, and up to three-meter drop protection. Those model details matter when comparing results rather than relying on the Extreme name alone.
The informal test unfolded in three stages:
- Water: Fatmi ran the drive under a kitchen faucet for three minutes, then submerged it in a pot of water. After approximately three to four hours of air drying, it reportedly worked when connected to a computer.
- Dust and debris: The SSD spent roughly an hour buried in unused cat litter. After Fatmi brushed particles from the USB-C port with a soft, dry toothbrush, it remained operational.
- Impact: Fatmi reports dropping the drive three meters onto a tiled apartment floor. It subsequently connected to both a computer and an Android phone, with files reported intact and no visible enclosure damage.
These are the reporter’s observations, not tests independently reproduced by WindowsForum. They demonstrate that one unit remained usable after a specific sequence of mishaps. That is worthwhile evidence, provided the conclusion stays that narrow.
IP65 does not mean waterproof—or shockproof
SanDisk separates its ingress protection claim from its drop-protection claim. Its official product documentation advertises IP65 resistance and up to three-meter drop protection, with the protection claims based on internal testing. Neither is presented as unlimited protection against accidents.
For water exposure, the manufacturer’s specification is precise: testing with water flow at 30 kPa for three minutes, followed by a requirement that the drive be clean and dry before use. It does not describe immersion as part of that protection.
That makes the pot-of-water episode an interesting survival anecdote, not evidence that owners should treat the drive as submersible.
The faucet comparison also needs care. Fatmi discusses household plumbing pressure, but the report supplies no measurement of pressure or flow at the drive. A tap turned halfway is not a calibrated test setting. Consequently, the experiment cannot establish how its water exposure compared with SanDisk’s specified conditions.
The practical distinction: surviving an exposure outside a stated specification does not expand that specification.
The cat-litter test needs a different interpretation
The report also mixes up the IP65 digits when discussing dust. In the IP rating system, the first digit describes protection against solids and the second describes protection against water. Thus, the 6 concerns dust protection; the 5 concerns water jets. Zebra’s technical explanation of IEC 60529 confirms that distinction.
An hour in unused cat litter is certainly an inventive household ordeal. It is not, however, a controlled dust-chamber test, and it cannot show whether any particles entered the enclosure.
What it does establish, according to Fatmi’s account, is that the drive still operated after the exposure and subsequent cleaning. That is reassuring for this unit, without turning the litter tray into a certification laboratory.
For owners, SanDisk’s instruction is more useful than reproducing the experiment: the drive must be clean and dry before use. The reported three-to-four-hour drying period should not be interpreted as a manufacturer-approved waiting time.
A surviving drop is not a complete data-integrity test
The three-meter fall most directly matches SanDisk’s advertised drop-protection height. Fatmi’s reported result—continued accessibility and no visible damage—is consistent with that claim. SanDisk nevertheless describes the protection as “up to” three meters, not as a promise covering every impact scenario.
The report does not document repeated drops, impact orientation, or a systematic comparison of every file before and after testing. Checking the drive on a second device adds a useful accessibility check, but it does not supply those missing measurements.
This is an evidence boundary, not a reason to dismiss the result. The drive survived a substantial reported fall. The test simply cannot establish how every unit would behave, whether repeated impacts would produce the same outcome, or whether long-term reliability remained unchanged.
What Windows users should take away
For a portable SSD used alongside a Windows PC, this account offers reassurance about accidental physical abuse—not permission to abandon caution.
The sensible approach is to:
- Follow SanDisk’s clean-and-dry requirement before reconnecting an exposed drive.
- Treat successful reconnection as a reason to secure important files, rather than an invitation to repeat the experiment.
- Keep a separate copy of irreplaceable data instead of making one rugged drive its sole home.
- Distinguish enclosure durability from long-term storage reliability.
Fatmi’s SSD emerged from an unpleasant afternoon apparently unscathed. That supports a favorable assessment of this unit’s physical resilience. It does not make the drive waterproof, indestructible, or a substitute for backups.
A tough enclosure is welcome insurance against clumsiness. A second copy remains the better insurance against losing the files inside.
