Inserting drives

Inserting a drive generally works well; most of my 2.5" SSD and HDD drives inserted smoothly and easily with no force required. The internal of the case looks to be of robust construction.

Insering one or two drives took more force than others, and I never could get one hard drive to insert at all. Tolerances might be involved, and presumably that one problem drive was “off” a little, but not in a way that I could see when comparing it directly to another one.

Heat and noise

No noise whatsoever, though a hard drive makes its own noise of course. An SSD is generally silent.

After running an 80GB clone to a drive in the FirmTek U3 case, I was impressed with how well the case shed heat; it just ooze out the generous venting holes. A hot running drive would find the FirmTek U3 a low-stress environment.

A backup use case for swapping drives—

As part of a backup process for a critical local server machine, the internal SSD is cloned to six different bare 2.5-inch drives (some SSD, some HDD), something for which I have used the NewerTech Voyager for some years via Firewire800.

In this situation, the bare drives are older and slower drives are not ones I’d otherwise use, but are nonetheless quite suitable for backup. But spending money for a case for each of these older drives is unappealing, and this would also make storing them considerably more bulky than just the bare drives.

Accordingly, the FirmTek U3 makes a fine replacement for the older Voyager Firewire 800 unit I have and the backups ran notably faster than before.

Performance

DiskTester is part of diglloydTools. The DiskTester run-sequential test writes 1000 equal-size files to the drive, then read/verifies the data.

Performance is outstanding for both 3G and 6G SSDs, and appears to reflect the May 2013 (approx) firmware update for various USB3 devices.

Swappable drives or fixed drive?

A key feature of the FirmTek U3 is its ability to swap drives in seconds. So naturally the question arises as to the considerations for a tool-free swappable case versus fixed-drive alternatives.

Drive swapping is appealing in certain environments requiring multiple drives, but this also raises the issue of how to protect the bare drives; as an alternative one can also install each drive in its own self-contained case (e.g. the OWC Mini). But for digital video users on the go, a small hard-case with a dozen or so bare drives is a big win on space and weight as compared to having each of those drives installed in its own relatively bulky case.

Specific workflow requirements suggest which solution is best; considerations include size/bulk/weight, protection of the units from physical damage, redundancy, etc. Especially for travel, weight and bulk might be special considerations.

Considerations of swappable vs fixed

A comparable portable unit to the FirmTek U3 is the OWC Mercury Elite Pro Mini (“OWC Mini”). Like the FirmTek U3, it has an aluminum case:

  • The FirmTek U3 allows swapping any 2.5" hard drive or SSD in seconds without tools via a spring-loaded front door.
  • The OWC Mercury Elite Pro Mini is a self-contained unit; a drive can be swapped with a screwdriver, but it is really intended as a self-contained unit.

For travel backup, I prefer the diminutive, pocketable OWC Mercury Envoy Pro EX.

Points of comparison:

  • The FirmTek U3 is about one inch (2.5cm) longer than than the OWC Mercury Elite Pro Mini. The difference is apparently the size increase needed to support the drive latch / swapping feature.
  • The FirmTek U3 is very well ventilated via many holes on the sides and bottom; it would be the conservative choice for hot-running 2.5-inch drives.
  • The OWC Mercury Elite Pro Mini supports both USB3 and eSATA, which might be important for users with multiple systems some of which do not have USB3.
  • The FirmTek U3 price is about $100 versus about $60 for the OWC Mini USB3/eSATA (or about $38 for the OWC On The Go). So the extra cost buys the hot-swap feature (and the high quality case, and I do strongly prefer aluminum cases).
