OCZ Vertex 4 solid-state drive
This SSD is fast, but it’s also good value -- apart from the lowest capacity model
- Excellent read and write speeds
- Good value for mid-capacity drives
- Only higher capacity models are fastest
- Lowest capacity 64GB model is comparatively slow
OCZ’s premium solid-state drive would make an excellent upgrade for any notebook or PC running a spinning-disk hard drive. Super-fast flash storage and a carefully designed controller makes for a drive that’s a great performer for both reads and writes.
Price$ 115.00 (AUD)
OCZ is a flash memory company, with a solid history in enthusiast-level RAM since 2002. It’s since moved out of the RAM market, but has a great reputation for producing some of the best solid-state storage drives and USB flash drives available.
The Vertex 4 is the company’s mainstream, high-performance solid-state drive. It’s available in 64GB, 128GB, 256GB and 512GB un-formatted capacities, although formatted capacities will obviously be slightly lower. We tested a 128GB Vertex 4.
OCZ Vertex 4: Design, setup, and specifications
The Vertex 4 is a standard-size 2.5-inch drive, measuring 9.3mm thick, so it should fit in most non-Ultrabook notebooks as well as any desktop PC (it comes with a 3.5-inch desktop drive adapter).
Its performance figures do seem to aim it at the enthusiast-level, custom-built desktop PC, though, and as a result its price is slightly higher than you’d expect from a drop-in mainstream hard drive replacement.
The drive is a no-nonsense black, dark brushed metal on some surfaces. There’s a sticker that tells you the brand, model and capacity, and the requisite SATA and power connectors, and that’s it. No fancy aesthetic dalliances, just a black box that’s packed to the brim with high-end flash memory chips.
The OCZ Vertex 4 is a SATA III drive, although it’s fully backward compliant with SATA II as well. Being an SSD it’s got extremely low power requirements — 2.5W during operation and 1.3W while idling — so it’s much more efficient than a traditional hard drive.
OCZ Vertex 4: Performance
As the middling drive in storage capacity, the 128GB model is also middle of the pack in its quoted performance figures. OCZ claims sequential read and write speeds of up to 560MB/s and 430MB/s respectively, while the lesser 64GB makes more conservative claims at 460/220 and the higher-end 256GB and 512GB models are rated to 560/510. IOPS performance is identical between 128GB, 256GB and 512GB models but the 64GB lags behind again.
This is an interesting situation, since it clearly positions the more expensive and higher capacity drives as the ones to choose for maximum performance in a high-end system. If you don’t have the money, though, you’re forced to put up with (slightly) lesser performance. We wouldn’t choose the 64GB model, while the 256GB model offers the best price/performance figures with the 128GB trailing closely behind.
In our CrystalDiskMark benchmarks, we recorded performance figures of 508MBps and 317MBps for sequential read and write using 1GB data blocks, and HD Tune gave us an average transfer rate of 220MBps and 175MBps read/write. The SSD-optimised ATTO disk benchmark returned best-case figures of 542MBps and 208MBps read/write — excellent performance from a drive that generally bests the Crucial M4 256GB SSD.
OCZ Vertex 4: Conclusion
THe OCZ Vertex 4 can be found in online stores both locally and internationally for a reasonably small price premium over competitor drives like the aforementioned Crucial M4, and we think this price premium is worth paying to get noticeably increased performance.

If you’re looking to invest in your next work horse laptop for work or home use, you can’t go wrong with the MSI GE63.
If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
Touch screen visibility and operation was great and easy to navigate. Each menu and sub-menu was in an understandable order and category
The printer was convenient, produced clear and vibrant images and was very easy to use
I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.
It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.
