The 8mb cache is an error, the drive actually has a 16mb cache. 
They are alright, just that they ripped people off with their rebates, the worse rebate company every. I’d never buy anything at tigerdirect.com that has rebate. But since this item has no rebates, good deal
Nope it only has 8mb cache because it is the [B]ST3500830AS[/B] model number here is the specs straight from the Seagate site
