B&H Photo won the contest for cheapest SSD this Prime Day with the SanDisk 4TB Creator Series, at just $350 down from $1050, a whopping 67% discount or $700. At less than $90 per TB, it is cheaper than anything we’ve seen over the past 72 hours. Hurry up though as the offer ends in about 11 hours.Backed by a 3-year warranty and capable of hitting speeds of up to 1000MB/s, the Desk Drive is technically a little big for an external SSD. Rivals tend to be flatter or altogether smaller, while some don’t need an external power source (this one does).However, you can’t beat it dollar for dollar. Either for performance or for capacity plus it even comes with Acronis award-winning True Image data backup software, which diligently (and transparently) copies all your files onto the SanDisk Creator Desk Drive.With read speeds of up to 1GBps and a huge capacity, this is the best value for money SSD you can buy right now, especially as you get a free backup software as wellView DealAlso considerBelow are some alternatives to SanDisk's best-in-class portable SSD.The 8TB version of the drive is not as good value for money but still delivers fantastic performance for the price.
