The hard drive of my Maxtor external box to let go without warning: my farewell given 1GB! My choice in Toshiba focused on that I do not know for its HDD. After several quick and definitive failures on two hard drives Seagate I said enough! I let a chance to Toshiba, so the disk is silent it is undeniable, but not very fast for a 7200 RPM, the more cache memory is only 8MB! Ridiculous in our time, there by cons 64MB Seagate drives really make the difference ... as long as it works! So put a replacement in my Maxtor external box, the Toshiba drive was not recognized. I had to format it in the rules connected SATA in my lap, then disassemble and integrate it into my external box, there no problem, silent but not fast this is my conclusion. For backup it is not annoying, for as against primary drive in a tower ... where I will avoid, not enough cache, however this value is not mentioned anywhere on the site of Amazon, c It is a shame because inconvenient to establish a true comparison between different hard drive brand. I found this information on the label that was stuck on the anti static bag the hard drive, even on the disk itself! Toshiba was ashamed as if to mark a cache ridiculous on its product ... In short, good but not great.
