The Seagate 600 Pro's additional over-provisioning may still be worth investing in if you have an exceptionally heavy write workload in a product like MySQL, but it's generally overmatched in terms of raw performance.

What really sets this drive apart, though, is the amazing MySQL Enterprise performance, especially at low-thread counts, where the drive delivers more than three times the throughput of other SSDs.

Reviews Word on the street for the Toshiba HK3R2


8.0
To address that concern, Toshiba has baked two kinds of power protection into the drive—Power Failure Management (PFM) and Power Loss Protection (PLP).

8.8
8.8Toshiba's HK3R2 SSD is targeted at entry-level enterprise customers, which is reflected in the product's packaging and branding, which are both pretty much non-existent.

What People Are Saying Give it to me straight

Performance

Finally, in VDBench, which we use to test disk read/write performance in enterprise storage scenarios, we saw excellent performance from the HK3R Series (480GB).
by PCMag (Jun, 2014)
It was somewhat slower in random single-threaded reads than the Seagate drive, but nearly twice as fast in random writes.
by PCMag (Jun, 2014)
PCMark 7 and PCMark 8 are also used for evaluating storage performance using real-world application traces.
by PCMag (Jun, 2014)

Capacity

The controllers can even use free space in the user area (the part of the SSD's NAND flash that isn't overprovisioned).
by techPowerUp!
As we begin our test, the SSD controller has vast amounts of free space/OP area at its disposal, so it pumps its highest write IOPS out then.
by techPowerUp!
Once the overprovisioned (OP) area is full, we see write IOPS drop like a rock until it plateaus, with the odd spike as the controller finds free space to use.
by techPowerUp!

Thickness

In the 32-thread test, the gap wasn't nearly as large between the two drives, but it was still significant.
by PCMag (Jun, 2014)
You can also see the two large shiny capacitors that provide just enough power in case of a power loss for the controller to write its data to flash.
by techPowerUp!
Two large capacitors provide a little bit of power for the SSD to write all its data to flash in case of a power failure.

Power

If the SSD detects that drive power has dropped below a predefined level, the SSD automatically transfers power draw to the supercapacitors on the SSD itself.
by PCMag (Jun, 2014)
The HK3R series includes on-board capacitors and firmware protections designed to ensure data in-flight is never lost, even in the event of power failure.
by PCMag (Jun, 2014)
The contents of every data write in progress are retained as well—meaning that if a write fails halfway through due to power loss, the original information is always kept in a backup location on the drive.

Like most recent SSDs, the Toshiba HK3R2 uses the SATA 6 Gbps interface.
by techPowerUp!
The Toshiba HK3R Series (480GB) ($648), a SATA SSD, is the fastest enterprise drive we've ever tested—and one with some fascinating data protection mechanisms.
