The Toshiba OCZ VX500 (256GB, 512GB, 1024GB) SSD Review
by Billy Tallis on September 13, 2016 9:00 AM ESTSequential Read Performance
The sequential read test requests 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.
The VX500 delivers very good sequential read performance, in the same league as the Samsung 850 EVO and SanDisk Extreme Pro. Because the spread of scores on this test is so small, this only represents a slight improvement over the Vector 180.
Power consumption is quite a bit lower than the competition and efficiency is again near record levels.

The VX500 starts out with very good QD1 performance and very little room for improvement. It reaches the limit of the SATA interface by QD4, and power consumption is nearly constant across the whole test.
Sequential Write Performance
The sequential write test writes 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.
The OCZ VX500 fares very poorly on this test. The drive is filled before the test is run, and apparently the VX500 did not finish flushing the SLC cache before the performance measurement began. These numbers thus represent the worst-case write performance for the VX500, while some TLC SSDs will continue to degrade under a longer write load.
In spite of the extra background work during this test as the VX500 copes with an already full SLC cache, it maintains very low power consumption. Efficiency is still a regression relative to the Vector 180 for the smaller two sizes, but the 1TB model manages a slight improvement.

Most drives exhibit little or no scaling with queue depth, and the smaller two VX500s follow this pattern. The above plot of the 1TB model's behavior looks very odd, but an inspection of the second-by-second performance data (below) reveals that it it periodically escaping from the low-performance state and delivering write speeds near the limit of the SATA interface. On a shorter test with less data written beforehand, the smaller models would likely also have shown their good side for some or all of the test.

How is the after sales service of these drives since Toshiba take over? I have heard some horror stories of RMA with OCZ in past.JebSpringfield - Tuesday, September 13, 2016 - link
I bought one OCZ drive a year after Toshiba took over. The SSD failed after one month, and they replaced it with a better model (I had to pay for the shipping), after another month or so, the new drive also failed. I contacted them again but this time I said I was not going to pay for shipping. They agreed, and sent me their top of the line model which has 5 year warranty and it's been working fine (knock on wood) for a bit longer than a year.Sorry but I don't remember the models.

While that doesn't speak to the quality of the drives, at least the customer service stepped up. The old OCZ days were just fraught with stories about the customer service affectively being MIA.StevoLincolnite - Tuesday, September 13, 2016 - link
...I'm still running a 64Gb OCZ Vertex 2 from 6-7 years ago... I WANT IT TO DIE SO I CAN UPGRADE.gammaray - Wednesday, September 14, 2016 - link
both my ocz vertex III and Agility III are still running fine lol. Meanwhile i bought an assorted battery of other SSDs, Main rig running Sandisk Extreme Pro.creed3020 - Wednesday, September 14, 2016 - link
Likewise! I have that same drive as my boot drive for my HTPC. Its definitely slower than it once was but thankfully it keeps on chugging. My next gen HTPC will include a newer, bigger boot drive. Not sure what will happen to the SATA II drive when I rebuild...Bullwinkle J Moose - Monday, October 3, 2016 - link
A Vertex 2 is Super Easy to KillJust follow OCZ recommendations on upgrading the firmware
(NO, I am NOT joking)
B.T.W.,
Anandtech really needs to update their testing procedure for SSD's
The original Vertex could copy and paste a 2GB file (to and from the same drive) at a blistering rate of 3.6 - 3.7 MB/sec
A Samsung 840 Pro can copy/paste the same file at 56.8 MB/sec
A Samsung 850 Pro can copy/paste the same file at 113.7 MB/sec
YES, AN 850 PRO IS TWICE AS FAST AS AN 840 PRO!
Disclaimer:
ALL tests made with XP-SP2 on SATA2 Ports using IDE protocol
Your results will vary depending on O.S. / Port Type and Protocol
Hardware and O.S. were kept identical to that used when testing the Vertex 1 & 2 which are no longer available for testing on newer hardware

Hi JebSpringfield,As this is my first post on this article please allow me to identify myself as a Toshiba America Electronic Components (TAEC) representative. Thank you for your comment and great to hear the current replacement drive is working well for you. We greatly appreciate both your business and support.

I won't be taking the risk. They refused to honor their warranty when my OCZ DDR2 sticks failed. Lifetime warranty my azz.....ocztaec - Thursday, September 15, 2016 - link
Hi fanofanand,Thank you for your comment and your business. I'm sorry to hear that you had issues in the past. We understand how you feel and hope that one day we will have the opportunity to demonstrate the reliability of our current Toshiba products. Thanks again for your feedback.
