Among all its troubles, the Japanese company finds time to make a happy debut to its new BiCS technology with 64 layers of storage Compressed and advanced
It can not be said that the "SSD They managed to steal the success at the Computex 2017 exhibition, but they certainly provided us with quite a few interesting topics of conversation as part of it thanks to the premieres of new and advanced storage chips from a number of different manufacturers. We've already told you about the cool development of IMFT - and now it's time to turn to one of their competitors, Toshiba.
It could very well be that in a few months' time it will be heard that the entire NAND chip production division of the Japanese company, which is in huge debt, will be transferred to another company, with options such as Western Digital, Intel And even Apple being thrown into the air, but until that happens (if it does) there is an attempt here to broadcast business as usual - with the announcement of a plan to switch to chip use NAND 3-D in all products, with a new XG5 model designed for the various computer manufacturers, and may be the one you'll find on your next laptop.
The XG5 is intended to be successor to the XG3 and XG4 models, which were based on chips NAND Planar in MLC configuration and TLC configuration respectively, with the use of 3D TLC chips in the BiCS64 architecture (the third generation developed by Toshiba) with a 3 "storey" structure, which is a kind of alignment of technology with the capabilities presented by IMFT and Samsung in the field. We do not have specific information about the surface area of these chips, but we do know that Toshiba has BiCS256 chips with a volume of 512 GB in each layer and XNUMX GB in each layer - which could undoubtedly offer compression storage Double and even triple compared to the most advanced planar chips, thus providing identical and even better performance (according to the company) in power consumption, significantly better dimensions and price. We are holding fingers.
The new drives will be offered in an M.2 configuration with a common length of 80 millimeters in a single-sided configuration, with volumes of between 256 GB and one terabyte according to the manufacturer's preferences, guaranteeing impressive continuous transfer speeds of up to 3 GB per second in reading Up to 2.1 GB per second in writing, power consumption of no more than 4.6 watts per operation and only 3 milliwatts in sleep mode - and a reasonable MTTF (Mean Time To Failure) time of 1.5 million hours. We have no information about controller God-SSD Inside, but there is a good chance that this time, too, this is a self-developed controller Toshiba, And possibly the same controller we've seen on the XG3 and XG4 models with the latest firmware to support the new memory chips.
We have no details about the XG5's random performance, but we assume it will be at least as good as those of previous generations, with about 120,000 IOPS or 130,000IOPS for reading and writing small 4K files (in QD32 work of course). Does not break records in any way, but should suffice for most consumers - certainly if it will be combined with a fair cost.
The XG5 itself should not be available to home consumers officially, but it should definitely be coordinated for this market, probably under the brand OCZ - Just as the RD400 model that was and remains one of the most lucrative in the M.2 drive segment is actually the brother of that XG3. We are very much looking forward to these two new models, hoping that they will indeed be able to keep their promises and maintain the competitiveness of Toshiba, Before the seemingly inevitable transition to a new owner.
