The Toshiba OCZ VX500 (256GB, 512GB, 1024GB) SSD Review
by Billy Tallis on September 13, 2016 9:00 AM ESTAnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage and unlike our Iometer tests, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test.
We quantify performance on this test by reporting the drive's average data throughput, a few data points about its latency, and the total energy used by the drive over the course of the test.
The 1TB VX500 delivers a slightly better average data rate than the Vector 180, but is still significantly slower than Samsung's 850 EVO, let alone the 850 Pro. The smaller two capacities of the VX500 are slower than the Vector 180, with the 256GB VX500 about 20% slower than the 240GB Vector 180.
The average service time of the VX500 is relatively poor for an MLC drive, but still significantly better than planar TLC drives. The Vector 180 had top-notch latency with little dependence on capacity.
The number of latency outliers above the 10ms threshold ranks the VX500 below almost all MLC drives. The Crucial MX200 also performed poorly here; in both cases it is likely due to the use of an SLC cache (which is relatively rare for MLC drives) that is swamped by this long-duration test.
At the 100ms threshold the VX500 has a typical number of latency outliers for a budget MLC drive, but this is a significant step back from what the Vector 180 could do.
In spite of mediocre performance, the VX500 has great energy efficiency that is competitive with 3D NAND and close to the record set by the Crucial BX100.

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.
