Kingston's SSD lineup is as follows: They have HyperX-branded SSDs for enthusiasts and the mainstream market is catered by SSDNow brvà. The HyperX SSDs have sầu been fairly popular from what I've seen and we have sầu also reviewed the regular HyperX as well as the 3K variant of it.

However, the SSDNow lineup has always been a big mess in my opinion. There's V-Series, V+ Series, V100, V+100, V200 và V+200 -- but there is very little consistency in the products. The V100 and V200 are both JMicron based, but the V+100 is Toshitía & the V+200 is SandForce based. And the new V300 is also SandForce based. Add to the phối that HyperX SSDs are SandForce too and the lineup couldn't really get any more confusing.

Currently Kingston offers three SSDs with very little distinctiveness. I certainly hope that the V300 will simplify things và there won't be a V+300. The V+200 is still available (others are EOL) but I'm guessing it will be discontinued once Kingston has cleared their stocks. I don't have a problem with the SSDNow br& as a whole but I strongly dislike Kingston's naming system because the plus signs just don't make any sense. It would be okay if the plus sign stood for SandForce và the Vxxx was for example a budget Marvell-based drive, but currently the plus sign has no definite meaning. Considering Kingston has the HyperX lineup as well, I think the SSDNow should only consist of one Model at a time to lớn keep things neat and avoid hàng hóa overlaps; then the V+xxx wouldn't have sầu to lớn exist anymore.

Product branding criticism aside, let's look at the actual V300:

There's a question mark after the NAND because Kingston only told us that the NAND is 19nm MLC. However, Toshiba-SanDisk join-venture is the only NAND manufacturer who uses 19nm process (IMFT is 20nm, Samsung 21nm and Hynix is still 26nm as far as I know), so there really aren't any other options. Similarly to many other OEMs, Kingston buys NAND in wafers and then does the validation & packaging on their own. The sản phẩm numbers are also in-house and obviouslythere are no public datasheets, hence the info on the NAND is very limited.

Kingston branded NAND in the 120GB V300

Buying NAND seems lớn have become a trover ahy vọng SSD OEMs lately. If you go back a year, everyone was using pre-packaged NAND but now at least OCZ, ADATA, Kingston and Transcover are buying NAND in wafers. I believe sầu there's currently so much price competition (especially between SandForce OEMs) in the consumer SSD industry that costs need to lớn be cut wherever possible. Buying NAND in wafers is cheaper because there are no binning or packaging costs involved and you also get a ton of lower quality NAND. It's actually a rather small percentage of the NAND wafer that's suitable for SSDs và the lower quality NAND usually gets used in devices where endurance isn't as critical (USB flash sticks, lower-end smartphones/tablets).

You might have sầu noticed that most of the OEMs buying in wafers also make other NAND-based products. On the other hand, you also get the highest unique NAND dies that can be used in enterprise SSDs -- in the retail NAND market you would have lớn pay a hefty premium for those. The only concern I have sầu is that SSD OEMs won't give sầu us enough details about their NAND and its validation, which may result in lower quality NAND being used because the specifications are not public (for example Hãng Intel has always been very open about the endurance of their NAND, while Kingston wouldn't even tell us the original manufacturer). The price competition is very harsh & it can be tempting to use the lower chất lượng NAND but I hope this is just my pondering & we won't see this happening.

Kingston touted that they worked very closely with SandForce/LSI to lớn customize the SF-2281 platform for the V300. Now, even though the chip has Kingston's logo sản phẩm on it, it's the same SF-2281 that's available lớn everyone else. SandForce allows the client lớn customize the firmware by a certain degree but I don't know the exact level of customization that can be done (no straight access khổng lồ the source code, though). I suspect the bigger the client, the more customization SandForce is willing to offer because the client is also able to lớn put more resources into lớn customization. I spoke with one of Kingston's SSD engineers & he said Kingston's firmware is not stoông chồng SandForce (lượt thích for example Corsair's is), but a custom one where they have sầu tried to lớn piông chồng the best features from every firmware. What that really means in practice, I don't know, but let's see how it performs.
