The Sorcerer
oh wow...Xenforo!!!
As I've said on the previous Kingston review:
"We might/should see newer versions of V-series drives coming up with a better performance, hopefully with a good balance between sequential /random read and write tests."
......And see you shall.
Kingston India sent me a SSDNow V+ series 64 gigs Performance upgrade kit. Comes with the (almost) same bells and whistles but at the end of the day what matters is what can she do- give a goo stable sequential read/write and random read/write scores or will it be "Geronimo" jump between the tests we seen earlier?
Advertised specs, package and closer look:

This is a generation 2 SSDNow V+ series drive but their PR was kind enough to provide a 1st generation drive as well for comparison test.Advertised specs, package and closer look:
*img51.imageshack.us/img51/9967/advertisedspecs.jpg
Judging by the advertised specs alone, it has better sequential read but more than 2 times the write speed compared to the V series reviewed earlier. Power consumption is advertised to be low on active and load (most likely the SNVP325-S2B/64GB will be coming in desktop and laptop upgrade kits) with double the life expectancy. This is probably meant to be their mainstream SSD drive. Kingston's new teeth so far looks good- on paper.

With the usual connectors and the Kingston-labelled Acronis back-up disk, Kingston gave a plastic external enclosure with the really small USB cable.

There's always room for improvements, one of them being that the build quality need to be better.

After opening it up, all the NAND flash chip, controller and cache is on the other side of the casing protected by a really thick thermal pad. After removing the PCB, the drives is armed Toshiba T6UG1XG controller that supports TRIM but not NCQ, next to there's a Micron 128MB cache. The rest are Toshiba TH58NVG7D7EBAK0 flash NAND chips.

Atto Benchmark v2.41: Sequential Read and write with 8MB transfer.
The ATTO Disk Benchmark performance measurement tool is compatible with Microsoft Windows. Measure your storage systems performance with various transfer sizes and test lengths for reads and writes. Several options are available to customize your performance measurement including queue depth, overlapped I/O and even a comparison mode with the option to run continuously. Use ATTO Disk Benchmark to test any manufacturers RAID controllers, storage controllers, host adapters, hard drives and SSD drives and notice that ATTO products will consistently provide the highest level of performance to your storage.

HD Tach 3.0.4.0: Quick bench
HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.

In 3 tests (ATTO, HD tune's file benchmark and Crystal disk) it shows that it can around 200-230MB per second sequential read and 146-150 MB per second in sequential write. Sequential read/write tests shows a difference between the 1st and 2nd gen drive. 4K read performance could have been better.
Conclusion:
Furthermore, Kingston needs to make an improvement on their website. The first gen SSD drive has VBM1801Q firmware with the TRIM option disabled. I went to their website ( specifically- this link) to flash it with VBM19C1Q firmware to enable TRIM but it didn't come with any firmware update link whatsoever. They really need to have their own proprietary firmware updater like the Samsung SSDs with the same controller or provide the proper instructions to make a self-boot USB drive and download link for the firmware. It leaves a bad impression when companies don't support discontinued drives, specially which are not obsolete and within their warranty period.
it seems like a decent drive if it had NCQ support. No proper conclusion can be made as Kingston India recently informed that they don't have 64GB kits in retail, rather 80GB and 160GB kits are available for which they didn't provide any price for that as well. I've contacted my usual dealer but they don't stock anything from Kingston.
Conclusion:

Crystal Disk info detects SNVP 325-S2/64GB as SNV325-S2/64GB. This drive came as "Performance upgrade kit" so P stands for Performance I guess but if you are buying a SNV325-64GB SSD drive rather than the kit, wouldn't be suprised if both are the same drives. If you have checked the HD Tach benchmark above, that too detects the drive as SNV325-S2/64GB.*img255.imageshack.us/img255/6681/ssdpitch.th.jpg
Kingston V+ series is pitched as "Ideal for corporate environments" in their website (India and U.S.) but the second generation under this series is more like a second generation of the v series drive- and I say that for a good reason. *img3.imageshack.us/img3/3194/dsc02505gi.th.jpg
The first generation v+ SSD drive (now discontinued) came with a Samsung YK40 controller that supports NCQ and TRIM (you need to update the firmware to version VBM19C1Q to enable TRIM). The second generation drive comes with the same Toshiba T6UG1XG controller from V series I reviewed earlier which doesn't come with any NCQ support. NCQ is really important as its meant for random input-output performance and implementing this as a norm as this is happening for a pretty long time in mechanical hard drives. Moreover its rather strange to see a second generation drive meant for business and corporate use with no NCQ support while the first generation does.
