The async flash really loses a lot of performance in this test and this is the main reason why I dislike seeing asynchronous flash paired with SandForce controllers. Using the 50% of total flash capacity taken we get a better look at how a SSD performs in user systems.

SSDs also need time to recover, either with TRIM or onboard garbage collection methods.ĭrives with Data Testing - 25%, 50%, 75% Full States and Dirty / Empty Testįiles needed for 60 (64GB), 120 (128GB), 240 (256GB)Įmpty but Dirty - a test run just after the fill tests and shows if a drive needs time to recover or if performance is instantly restored. The purpose of the Drives with Data testing is to show how a drive performs in these 'dirty' states. SSDs perform differently when used for a period of time and when data is already present on the drive. You will be able to perform this test at home with the files provided in the article - full instructions are included. Benchmarks - PCMark Vantage - Drives with Data Testing PCMark Vantage - Drives with Data Testingįor a complete breakdown on the Drives with Data Testing please read this article. Let's go to the next page and see the advanced tests that we came up with to show this phenomenon. The drive performs very well here without data, but asynchronous flash slows greatly when data resides on the flash. For most users these are the tests that matter since many of the old hat ways to measure performance have become ineffective to measure true Windows performance. Windows users can count on Vantage to show them how a drive will perform in normal day to day usage scenarios. PCMark Vantage is easy enough for even the most casual enthusiast to use yet supports in-depth, professional industry grade testing.įutureMark has developed a good set of hard disk tests for their PCMark Vantage Suite.

Regardless of whether the benchmarker is an artist or an IT Professional, PCMark Vantage shows the user where their system soars or falls flat, and how to get the most performance possible out of their hardware.

PCMark Vantage is perfectly suited for benchmarking any type of Microsoft Windows Vista PC from multimedia home entertainment systems and laptops to dedicated workstations and high-end gaming rigs.

PCMark Vantage is the first objective hardware performance benchmark for PCs running 32 and 64 bit versions of Microsoft Windows Vista. When we tested the ADATA SP900, another 0-provision drive with asynchronous flash, we didn't have working TRIM. The third key feature, one that isn't really advertised, is TRIM working on the drive. I'd go as far as to say on an asynchronous drive you won't want to do that - we'll show you why later in the review. LSI SandForce controllers use all of the space you don't have occupied as spare area so this really doesn't affect performance until you get a lot of data on the drive and start taking up the last 7%. You may have noticed the full 256GB data capacity size and started thinking Marvell or another controller, but Transcend uses SandForce's 0-provision programming on both the SSD720 and the SSD320. Most companies are only using 7mm on flagship offerings. There are very few low cost asynchronous flash SSDs available in the 7mm package. The first is the 7mm z-height form factor. There are three key standout features on the SSD320. The sequential read performance is the same for both models, but the sequential write speed is 10MB/s slower on the SSD320.

The specifications list doesn't list any performance data, but we did find a 560MB/s read and 530MB/s write rating in a PDF file that covered both the SSD720 and SSD320 side-by-side. Please click here for more information.Transcend offers three capacity sizes for the SSD320 series of products, 64GB, 128GB and the 256GB model that we're testing today. Systems for use with the PCIe M.2 SSD must have an M.2 connector with only an M key.Warranty does not apply when SSD Scope's lifetime indicator displays 0% within the warranty coverage.Please click here for more information about the Transcend Warranty Policy.Some motherboards only provide PCIe x2 connections for the M.2 slot, creating a bottleneck on even the fastest drives.Terabytes Written (TBW) expresses the endurance under the highest capacity.The workload used to rate DWPD may be different from your actual workload, which may vary due to host hardware, software, usage, and storage capacity.Speed may vary due to host hardware, software, usage, and storage capacity.
