BUY TWO GET ONE

2tb usb stick

A while ago I bought a pair of generic 2TB USB sticks on fleabay. In the mail was a packet but only one stick was present. The vendor offered to refund for one or optionally send me another one. I asked for a second USB stick. I wanted two of them originally which is why I elected to be one more sent. For the most part vendors on fleabay realize mistakes are commonplace. Earlier I ordered two USB-C cables which surfaced as desired. USB-C is a growing segment which is why cables and chargers are being accumulated.

The write speeds of the 2TB USB stick is better than expected at about 15 MB/s flat. This is plenty fast enough to play 4K media easily. Immediately the utility of the USB stick with my BD player and 1000 movies to select from. Unplayable video can be moved quickly to another folder for transcoding.

While slow read and write, the USB stick at 2 TB is eye opening. The capacity is amazing given the cost. USB sticks however are not suitable for cold storage. Blu-ray discs can survive for a long time but flash memory has retentivity issues that can damage files. While redundancy can be added to archives the real problems cannot be overcome easily.

THE ADJENDA

The low cost USB stick ordered are the USB-A type which are still common and the goal is to have storage for secure rotation for backup. 50GB BD discs are fine for malware protection of vital documents but the USB stick has capacity for more mundane archival storage. USB sticks at 2TB are close to LTO-6 tape in capacity with lower media costs. Most likely the low cost USB sticks are QLC flash given the capacity.

2 TB of storage may be excessive but the device is enough to make a a lot of backups. Lower capacity models are available but the top capacity seems more relevant. Most likely a few 2 TB USB sticks will be procured primarily for backups. There are a lot of models of generic USB sticks. The sliding model s popular now that the patent has expired. Other designs are abundant.

Computer chess for years was very demanding. Now the EGTB endgame tables are able to be copied to a USB stick for backup. Compared to the DVD-R backup which takes almost 300 discs the improvement with the USB stick is astounding.

Some older USB sticks are faster but the limited capacity does limit their utility. The Transcend 128GB stick uses a USB 3.0 interface but its read/write is not that good. Sometimes the read speeds are very low suggesting some cells are weak and need to be mapped out. USB sticks vary a lot which suggests that the flash memory uses is probably substandard speed grades which end up being sold in bulk at the low end.
