There are small files involved with the transfer and many folders must be created. &nbsp;I can't say how many but assume lots. &nbsp;That is probably the source of the slow down. &nbsp;Thanks.

I have a Macbook Pro with an SSD and an external Firewire 800 7200RPM drive. &nbsp;I cloned 210GB of data from the MBP to the ext drive. &nbsp;It took 1 hour and 10 minutes. &nbsp;<br />
<br />
Firewire 800 transfers at 780Mbs, which translates to 5820MB per hour or 582GB per hour. &nbsp;I got less than 1/2 of that in an hour. &nbsp;The 7200RPM drive and SSD factor in. &nbsp;How do I get some idea on how fast the actual transfer rate was?

True transfer rate?

Storage devices include any device used for storing and retrieving digital information. Hard disk drives (HDDs) use one or more rigid ("hard") rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. The primary competing technology for secondary storage is flash memory in the form of solid-state drives (SSDs), but HDDs remain the dominant medium for secondary storage due to advantages in price per bit and per-device recording capacity. CD-RW (Compact Disc-ReWritable) is a digital optical disc storage format that allows information to be stored outside the mechanical HDD.

Storage Hardware

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Storage

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.
