OCZ Vector 150 240GB in Detail
After acquiring OCZ’s SSD business, Toshiba didn’t do much rebranding. The brand name has been slightly changed and the logotype has been updated, but overall things are the same as they used to be. The packaging design has been left intact, for example. So, the Vector 150 is shipped in OCZ’s conventional packaging painted the traditional blue colors of the Vector series. We can even see the old name and logo on the box:
The accessories are traditional, too. The box contains an adapter with screws for installing the 2.5-inch SSD into a 3.5-inch bay, an “I Love My SSD” sticker, and a license for the backup software Acronis True Image HD which can be used to easily move all data from your old disk to the new SSD. OCZ puts an emphasis on the fact that the bundled software would cost about $50 if purchased separately.
The Vector 150 has the same housing as its predecessor, which is good since the original Vector was okay in terms of exterior design. It is a neat and solid metal brick with rounded-off edges. Having a height of 7 millimeters, it can be easily installed not only in ordinary computers but also in ultrabooks. On the other hand, the Vector 150 is heavier than most other SSDs, so we wouldn’t really recommend it for ultra-portable computers.
The sticker on the top of the case has the same design and color as the original Vector’s, so OCZ maintains consistency of its Barefoot 3 based products even in terms of their appearances.
Inside the 240GB Vector 150 we can find a conventional-looking PCB with three types of chips.
First of all, we can see an Indilinx Barefoot 3 controller marked as IDX500M00-BC. It is manufactured on 65nm technology and has a peak heat dissipation of about 2 watts, therefore it contacts with the case via a thick thermal pad. We can note that the Vector 150 uses the same revision M00 controller as we saw in the old Vector released back in 2012.
Then, there are Toshiba’s TH58TEG7DDJBA4C memory chips (ABL Toggle mode 19nm MLC NAND). The 240GB version of the SSD contains 16 of them, each chip incorporating two 64-gigabit NAND devices. The 8-channel Indilinx Barefoot 3 controller can use 4-way interleaving on each memory channel, which is optimal in terms of performance.
And finally, the PCB carries a couple of 256MB DDR3-1600 SDRAM chips (Micron D9PFJ) which make up a 512MB buffer for caching data and for storing a copy of firmware and an address translation table.
When it comes to the internal design, the Vector 150 only differs from its predecessor in the type of flash memory and PCB component layout. This difference is reflected in its specs:
- Controller: Indilinx Barefoot 3
- Interface: SATA 6 Gbit/s
- Flash memory: Toshiba’s 19nm MLC NAND with Toggle Mode interface
- Storage capacity: 240 GB
- Cache memory: 512 MB
- Sequential read speed: 550 MB/s
- Sequential write speed: 530 MB/s
- Random read speed (in 4KB data blocks): 90,000 IOPS
- Random write speed (in 4KB data blocks): 95,000 IOPS
Frankly speaking, the specs are not impressive at all. They are actually worse than the specs of the original Vector which was specified to have a random read speed of 100,000 IOPS. It may be odd because Toshiba’s memory is known to be somewhat faster than IMFT’s. There’s a simple explanation, though. The small reduction in the specified parameters is due to the new firmware rather than to the new memory. The firmware focuses on achieving higher sustained performance for long periods of time instead of scoring records in brief speed benchmarks.
The higher reliability of the Vector 150 must also be mentioned. The product comes with a 5-year warranty, allowing the user to write a total of 91.2 terabytes of data. This is equivalent to writing up to 50 gigabytes daily, which is more than specified by other makers of consumer-class SSDs.
