Agreed. Here is a cut/paste for a buyer review in ref to a Samsung IDE flash memory based 32Gb drive [1]: Reviewed By: on 6/17/2007 Rating: 5 Tech Level: high - Ownership: 1 month to 1 year Pros: Performance tests on Linux, UDMA-4, Raw IO. 50MBps sustained read. 26MBps sustained write. 2 MB erase block. 3698 4K random reads/sec. 24 4K random writes/sec. Cons: Wish it was SATA and cheaper. Other Thoughts: As is typical of all Flash drives, terrible random write performance, so don't expect to use this in a high-end Read/Write database application. You will be disappointed. ------ I can't vouch for the accuracy of this information - so ... consider it as but one data point. The Sandisk products (when they ship) will probably offer better performance than this product, but I expect to see the same general operational characteristics.
